Heat Pump vs Furnace: Which Will Keep Your Chicago Home Warm?

Thursday, January 16th, 2020

Are you questioning the best way to heat your home? Heat pumps have been a hot topic of discussion lately for their environmental friendliness. While they’re a popular heat source in the southern U.S., can they handle the notoriously brutal Chicago winters like a standard gas furnace?

When it comes down to it, both heat pumps and furnaces will keep your house warm. The real question is, which heat source will better suit your individual needs? Generally, choosing between a heat pump and a furnace comes down to your type of home, your comfort level, your access to fuel, and your personal preferences.

What Is a Heat Pump?

When weighing your options between a heat pump and a furnace, understanding how heat pumps work will aid your decision-making process. Many Chicagoans are familiar with how furnaces work—a gas burner heats air flowing through the system and pushes the air through your house’s ductwork. Furnaces depend on a fuel source such as gas or propane to heat the air moving through the system.

On the other hand, heat pumps work similarly to air conditioners, but in reverse—they draw in heat from the air, water, or ground outside of your home and concentrate it to redistribute the warmth throughout your home. There are three common types of heat pumps:

  • Air-to-air. Transfers heat between the outside air and your house using air ducts.
  • Mini-split. Works similarly to an air-to-air system but doesn’t require ductwork.

When Choosing Between a Heat Pump and a Furnace, Consider Your Individual Needs

Even in the coldest conditions, there’s a relative amount of warmth that heat pumps can extract from the air. With modern technology, both types of heating systems can do an adequate job keeping your home warm, even in the most frigid conditions. To help make heat pumps more accessible to homeowners in the northern U.S., some heat pumps are equipped with a supplemental electric heating element. In the end, it comes down to the benefits you personally want to get from your home’s heating system.

Environmental Impact

With a gas-powered furnace, your dependence on fossil fuels leaves behind a pretty large environmental footprint. Heat pumps can heat your home without depending on fossil fuels to provide heat. Even dual-source systems that use electricity as a heat source when the temperature is too cold to adequately heat your home, your environmental impact is considerably smaller than employing a heat source that’s fully powered by electricity.

Cost

If you’re looking to save money in the long run, consider the price of electricity versus gas in your area. If electricity is more expensive per unit than gas, a heat pump will generally cost more than a gas furnace and vice versa. Additionally, gas furnaces tend to have longer lifespans and cheaper maintenance costs than heat pumps.

Access to a Fuel Source

If you’re building a new home in a rural area, you may not have easy access to a natural gas utility, or you may want to save some additional money by avoiding the service altogether. Since heat pumps use the environment around you to extract heat, you can install them just about anywhere.

Insulation

Do you live in an older home with poor insulation or a new home with the top-of-the-line stuff? How your home is insulated can greatly affect how a heat pump functions in your home. A gas furnace can power through just about anything. If your house is drafty with old windows and insulation, a heat pump could struggle to adequately maintain higher temperatures.

Choose the System That Works for You

When it comes down to the nuts and bolts, both gas furnaces and heat pumps will be able to heat your home no matter where you live. The final decision comes down to your personal preferences and what you plan to gain from your home’s heating system.

The heating experts at Althoff Industries can help you weigh the pros and cons of both systems and help you determine the type of system that will work best for your home. Contact us today to schedule your home heating consultation.

Do Energy-Efficient Appliances Save Money?

Friday, December 20th, 2019

We’re always looking for new ways to save money without giving up the small luxuries we love. By switching to energy-efficient appliances, you could save hundreds of dollars per year.

Better yet, you’ll be keeping more money in your pocket, instead of paying it to the utility companies. That means more vacations and less painful bills and this switch will have minimal impact on your life.

Not only are energy-efficient appliances good for your wallet, they’re also beneficial for the environment as well. You’ll sleep easier knowing you’re making smart environmental and financial decisions.

Energy Star Appliances and SEER Ratings

If you’ve purchased an appliance in the past 25 years, you’re probably familiar with the Energy Star label. Energy Star is a U.S. Environmental Protection Agency voluntary program that helps businesses and individuals save money and protect our climate through superior energy efficiency.

According to the Energy Star website, “Since 1992, Energy Star and its partners helped save American families and businesses nearly 4 trillion kilowatt-hours of electricity and achieve over 3 billion metric tons of greenhouse gas reductions, equivalent to the annual emissions of over 600 million cars. In 2017 alone, Energy Star and its partners helped Americans avoid $30 billion in energy costs.”

SEER stands for “Seasonal Energy Efficiency Ratio,” and is the efficiency rating of an HVAC system, which measures the efficiency of specific appliances in your home. The SEER rating of an appliance—your AC unit, refrigerator, or your heating system—is based on a number of factors.

It is also important to note that the higher the SEER rating, the more energy-efficient the appliance will be.

Energy-Efficient Appliances Use Less Energy and Save You Money

Customers often wonder how they can save money by dropping money on new energy-efficient appliances when their older models seem to be functioning just fine.

Energy-efficient appliances can help you save money by using less energy and resources such as electricity, gas, and water.

Remember that your gas, water, and electricity bills aren’t set in stone. Utility companies charge based on the amount you consume every month.

Energy-efficient appliances use fewer resources than older appliances to complete the same task, which lowers your monthly utility costs.

Dryers

Dryers generally consume the most energy of any appliance. According to the Natural Resources Defense Council (NRDC), a typical household dryer consumes as much energy per year as an energy-efficient refrigerator, washing machine, and dishwasher combined. If you have an older model, that number could be even higher.

Energy Star certified dryers use 20% less electricity than a conventional model, which will save you a significant amount of money on your energy bills over time.

Washing Machines

Pair that energy-efficient dryer with an energy-efficient washing machine, you’ll enjoy even bigger savings on your monthly bills.

An Energy Star certified washing machine uses about 25% less energy and 33% less water than regular washers, according to Energy Star.

Energy Star also estimated that there are 74 million top-loading washers and 24 million front-loading washers—26 million of which are at least 10 years old—still in use across the country and these inefficient washers cost consumers about $4.7 billion each year in energy and water.

Energy-efficient front-loading clothes washers also require less laundry detergent than top-loading washers, so you save more money from week to week!

Refrigerators

There have been significant advances in the technology used in refrigerators over the last decade or so, which means that outdated refrigerators are using a ton of extra energy in many homes to this day.

The Energy Star certified refrigerators available today are around 10% more energy-efficient than models that meet the federal minimum energy standards.

If you have an older refrigerator, you can save even more on your energy bills by upgrading to a more efficient option. Energy Star certified refrigerators use up to 40% less energy than the conventional models sold in 2001.

Energy-Efficient HVAC Systems

By upgrading the HVAC system in your home, you will likely see a significant return on your investment over time.

Now, it may seem like a lot of cash upfront, but if you keep your new system well-maintained you will definitely see the savings in the long term.

According to the DOE, the most efficient central AC systems today use 30% to 50% less energy than those built in the mid-1970s. Even when a 10-year-old unit is replaced, the new air conditioner can cut cooling costs by anywhere from 20% to 40%.

In addition to that, heating your home actually costs you the most money, making up about 42% of your utility bill according to energy.gov. An outdated system with a low SEER rating is likely costing you a lot more monthly than you would like.

We have come really far when it comes to the technology available in modern HVAC systems in the last 20+ years. Talk to an expert and find out which HVAC system is right for your home so you can start saving.

Other examples of energy-efficient appliances available to consumers include:

  • Cooking appliances
  • Dishwashers
  • Toilets
  • Water heaters

Are You Considering Making Energy-Efficient Improvements to Your Home?

Maybe you are ready to take a step towards a more energy-efficient home and cost savings or you’re already there and your energy-efficient HVAC system needs maintenance. No matter what your case is, the experts at Althoff Industries can help with your energy-efficient appliance needs.

We’ve been serving the Chicago area for over 60 years, so we’ve done our fair share of energy-efficient home improvements. Contact us at 815-455-7000 and schedule your appointment today!

Fall Home Maintenance Checklist: Preparing for Cold Chicago Winters

Tuesday, October 29th, 2019

With winter fast approaching, it won’t be long until the cold weather and low temperatures are here to stay. With this in mind, it’s important to ensure your home is fully winterized. To keep your home running and reduce the amount you have to spend on repairs when the snow hits and the wind chill drops, take a look at our fall homeowner checklist.

1. Clean Your Gutters

Increasing precipitation will put your gutters to the test, so make sure they’re not clogged up with leaves and debris. If gutters remain clogged it can cause water to overflow and fall along the foundation of the building. Also, if the foundation is wet and then freezes, this can cause significant heaving and cracks.

2. Check Your Driveway

Even minor cracks in your driveway can cause major problems for your home. When water seeps into the driveway, it will gradually become uneven and less stable. If you don’t address the issue, this water could move to the foundation of your home and require costly repairs. With a little maintenance, you can prevent the need for these repairs and save yourself from some major headaches in the future.

3. Add Weather-Stripping to Your Home

If your home is full of drafts, you’ll find your energy bills during the winter will skyrocket. Weather-stripping is a quick and easy way to tackle drafts, and it’s something you can do yourself. Check every door and window for drafts and, if you find any, add weather-stripping tape to the affected area. This will prevent cold air from entering the property and minimize the amount of heat which escapes. As a result, you’ll be able to keep your home warm and cozy without spending a fortune on energy bills.

4. Make Sure All Exterior Wood Trim Is Properly Sealed

The wood trim around your exterior doors and windows is just a one-inch-thick pine board that can rot very quickly if not protected.

It’s important to keep exterior wood from rotting by keeping it properly painted and caulked. This is a prevention job most people can do themselves. Once the wood rots, however, you will likely have to call in a carpentry expert to replace the damaged areas. This could potentially cost you a lot of money.

5. Prep Your Lawn

First, make sure the soil around your foundation hasn’t settled. This can create areas for water to pool at your foundation. If you find a spot that seems as if it could cause pooling, simply fill it in with some soil.

Secondly, the cold temperatures will impact the grass but adding fertilizer can prevent this from happening. With dedicated grass protection products also available, you can ensure your lawn remains green throughout the winter months.

6. Arrange Boiler or Furnace Maintenance

You absolutely do not want to be without heat in the wintertime, so have an expert come out and check that everything is ready to go before things get really chilly. Faulty furnaces or boilers can be dangerous, so having yours checked will provide peace of mind and pretty much eliminate any risks.

When your boiler or furnace is working optimally and your air filter is changed or cleaned, you’ll spend far less on your energy bills, have better air quality and have complete control over your heating and AC systems.

7. Bring Outdoor Furniture Inside

Although outdoor furniture is designed to withstand some rain and extremely warm temperatures, this doesn’t necessarily mean it does well in sub-zero temperatures and snowstorms. Bring your outdoor furniture inside and make sure it’s stored at an appropriate temperature until you’ll be using it again. If you really don’t have the space to keep it indoors, you can try to use a waterproof furniture cover to prevent most of the damage.

8. Test Winter-Specific Equipment

If you own equipment or tools which you only use in the winter, you’ll want to check that it’s still working. There’s no use finding out your snow blower or snow plow doesn’t work in the depths of winter, so take the time to try it out now. Also, get the necessary maintenance work and repairs done on your equipment now, so you know it will be working when you actually need to use it.

9. Shut Off Exterior Faucets

If you leave exterior faucets open throughout the winter, there’s a good chance your pipes will freeze – which is a real headache. To prevent this from happening, remove any accessories, such as hoses, and shut off the exterior faucets completely. Rectifying freezing pipes can be time-consuming but shutting off the faucets doesn’t take long and will keep your pipework in excellent working condition.

10. Have Your Humidifier Serviced

Too little humidity is very common in the winter once the heat gets turned on, drying out the air and sometimes resulting in chapped lips, bloody noses and breathing issues. You don’t want too little humidity but you also don’t want too much humidity in your home.

A warm, functional whole-home humidifier can help easily keep all of the rooms in your house comfortable. You will need to make sure you change your humidifier pad/filter and that there are no leaks. If you do have a whole-home humidifier, you should definitely consider having a team of professionals come in to ensure that your system is in perfect working condition.

Keep Your Home Cozy and Warm This Winter

The experts at Althoff Industries can help you make sure that your home’s heating system is running perfectly before the weather hits the single digits. Don’t get stuck out in the cold! Give us a call at 815-900-5002, and schedule your winter maintenance appointment today.

Can I Get a Tax Credit for Switching to Energy-Efficient Appliances?

Monday, March 18th, 2019

As of the 2018 tax year, many of the federal tax credits for upgrading to new, energy-efficient appliances have expired. In the past, you were able to collect federal tax credits for energy-efficient water heaters, air conditioners, boilers, furnaces and other in-home appliances. Now, the IRS provides these types of tax credits only for residential renewable energy products. According to Energy Star, these tax credits should remain available through December 31, 2021.

The tax credits may have expired, but in many cases it’s still a cost-effective solution to update your major in-home appliances. Depending on the age of your water heater, air conditioner or furnace, you could be wasting valuable dollars every month by powering old, inefficient appliances.

For tax year 2018, we’ll explain some of tax credits you can still qualify for if you decide to choose a renewable energy appliance for your home. We’ll also illustrate some of the cost savings you can expect if you choose to replace your old appliances with energy-efficient ones in 2019.

What appliances can I still get a tax credit for?

The U.S. government has restricted the federal tax credit to apply only to equipment that uses alternative energy. You can receive a 30% tax credit through the end of 2019. After 2019, the credit will gradually decrease until it disappears completely for the 2021 tax year. You can view the appliances available to receive the tax credit on IRS Form 5695. Examples that still qualify for the residential energy credit include:

  • Solar water heater. These water heaters convert power from the sun into an energy-efficient heat source for your water. In order to be eligible, the solar water heater must be installed at your primary residence, not a rental property. At least half of the energy generated by the water heater must come from the sun.
  • Small wind turbine. These residential-sized wind turbines convert wind energy into electricity for your home. In order to qualify, the turbine must be installed at your primary residence; the residence can be a new, existing, or second home. The turbine must have a nameplate capacity of no more than 100 kilowatts.

How do I file my tax rebate?

Filing for your tax rebate is simple, as long as you meet the requirements. According to TurboTax, “To claim the credit, you’ll need IRS Form 5695. Work out the credit amount on that form, then enter it on your 1040. You should keep your receipt for the appliance as well as the Manufacturer’s Certification Statement, so you can prove your claim if the IRS ever conducts an audit.”

Will I save money by upgrading to energy-efficient appliances?

If you’re looking for an appliance upgrade, you don’t need a tax credit to see the cost savings. If any of your appliances have been around for more than 10 years, you can expect to see considerable energy savings when you upgrade to a newer model. For example, according to Energy Star, certified gas storage water heaters are, “about eight percent more efficient than a standard model.” Energy Star certified central air conditioners not only have higher seasonal energy efficiency ratio (SEER) and energy efficiency ratio (EER) ratings but also use about 8 percent less energy than conventional new models.

In total, Energy Star reports that, “By choosing Energy Star, a typical household can save about $575 on their energy bills and still enjoy the quality and performance they expect.”

Are you in the market to upgrade a major home appliance?

Why Does My Heater Make a Screeching Sound

Monday, November 26th, 2018

You finally get home after a long, chilly day. As soon as you come inside, you crank up the thermostat hoping to knock some of the chill out of your bones. But instead of being greeted with a warm, gentle breeze from the furnace, you’re startled by the sound of an earsplitting, hair-raising screech.

Your first thought is probably, “That sounds expensive.”

A screeching heater is unnerving. However, most of the time, it’s a simple fix that requires a bit of expert knowledge and skilled hands to repair. It’s not a sound that you want to turn up the TV and ignore, though—the longer your heater screeches, the more you risk costly damage.

Let’s take a look at the most common causes of a screeching or squealing heater.

Blower Motor Failure

Your furnace’s blower motor creates a lot of force—blowing enough air to warm the whole home is a tough job. While blower motors are engineered for the job, like any other machine, the parts will wear down over time with use. When this happens, these parts can literally “scream” for help—that’s the squealing or screeching noise you’re hearing.

  • First, it could be the blower motor bearings. As the lubricating oil breaks down with wear, the bearings can seize up and ultimately fail. When the bearings can’t move freely, they can emit a loud, unsettling screeching noise.
  • The screeching could be coming from the blower wheel. An out of balance blower wheel will cause noise, vibration, and over time ruin the bearings on the motor. A loud screeching sound can result from metal pieces rubbing together.

An expert furnace technician can find and fix the root cause of the blower motor problem. If you hear a screeching sound from your furnace, don’t put off the call. In many cases, a simple fix (like lubricating the motor bearings) can prevent further damage and costly repairs.

Regular furnace maintenance, like an annual tune-up, can spot potential problems with the blower motor and keep it in good repair.

Is a screeching heater keeping you up at night?

Serving the Greater Chicago area, Althoff Industries can help you rest easy knowing your home will be warm when the temperature drops. Your heater’s screeching is a cry for help—call us at 800-225-2443.

Why Is My Furnace Running but Not Blowing Hot Air?

Monday, October 29th, 2018

Your furnace clicks on and the blower motor is running, but the air coming from the vents is cold or cool instead of hot. Or maybe the air starts off hot, then turns cool before the furnace shuts down.

Let’s look at some of the solutions to this common furnace problem.

1. Check the air filter.

Has it been awhile since you changed your furnace air filter? If you use disposable air filters, we recommend checking them every month and changing them if they’re dirty.

A dirty air filter affects more than just your home’s air quality (though don’t get us wrong, that’s important). The humble air filter is at the root of many furnace problems.

A clogged, dirty air filter blocks the return air flow to the furnace, meaning:

  • There’s less air to blow out of your vents. This could account for your “cold air” feeling.
  • The furnace can overheat. The furnace is suffocating without enough air, so it has to work harder and run longer to heat your home. Imagine trying to run a marathon with a heavy cloth around your mouth and nose, and you’ll get the idea. Soot builds up on the heat exchanger over time, making it even less efficient. All this can easily cause the heat exchanger to overheat. Your furnace has safety controls that automatically shut down the burners in case of overheating. Though the hot air stops, cool or cold air will continue to blow for awhile in order to cool down the unit to safe level.

Try changing the air filter to see if this resolves your cold air problem. If that doesn’t help but you still suspect your furnace is overheating, it’s time to call in a professional HVAC technician. Repeated overheating will damage the heat exchanger and lead to a big repair bill.

2. Check the thermostat.

If you’re getting cool air instead of warm, the problem may not be your furnace at all. It may be an issue with the thermostat. Thermostats are fiddly things—plus, you never know who in the house might have done some “unauthorized adjustments.”

  • Make sure the thermostat is set to “heat” instead of “cool.” (Yes, this sounds obvious, but it’s been the cause of many a service call!)
  • If your thermostat has a fan setting, set it to “auto” instead of “on.” If it’s set to “on,” the blower fan may run continuously even when the furnace isn’t heating the air up to the set temperature.
  • Open the thermostat panel and gently blow out any dust or debris. A dirty thermostat can sometimes malfunction.
  • If your thermostat runs on batteries, try replacing them. Most thermostats run off your home’s central power with battery backup, but some run exclusively on battery power. Dying batteries can cause the thermostat to send incorrect temperature information to the furnace.
  • Ensure that the thermostat is firmly attached to the wall and none of the wires are loose or damaged.
  • Take note of the air temperature near the thermostat. A thermostat reads the temperature of the air immediately around it. Is the thermostat in a spot that is noticeably warmer than the rest of your house? The thermostat will apply that temperature to the rest of your home, which can lead to cooler air than you wanted as the thermostat tries to regulate the temperature.

If all of these things check out but you still suspect a malfunction, the thermostat may need recalibration or replacement.

3. For gas furnaces: Make sure the gas supply valve is on.

Have you had any repairs done lately? Someone may have shut off the gas supply valve to do a repair and then forgot to turn it back on. Without the gas supply, there’s nothing for your furnace to burn to create the heat. Check that the gas valve handle is inline (parallel) with the gas pipe—that means it’s on. When it’s off, the handle is perpendicular to the pipe.

If this doesn’t fix the problem, and you smell gas, turn off your gas supply and call a professional right away. Gas leaks are dangerous.

4. For gas furnaces: Check the pilot ignitor, flame sensor and/or pilot light.

Problems with your pilot light can cause your gas furnace to blow cold air.

Most modern gas furnaces have an electronic pilot igniter coupled with a flame sensor rather than a physical pilot light. These can malfunction—repairing or replacing them is a job for a professional HVAC technician.

A dirty or clogged pilot ignitor can prevent the furnace from igniting properly. While working with the ignitor is a job for a pro, you can check for a dirty ignitor if you know how and feel absolutely comfortable shutting off power to your furnace, taking off the front panel, and locating the ignitor.

If you have an older gas furnace with a standing (physical) pilot light, the light can go out. This is usually the result of the gas company shutting down the gas lines for maintenance or an emergency. Once you’ve confirmed that the gas line is safely back in operation (a quick call to the gas company is a good idea), try relighting the pilot light according to the instructions for your unit. If it won’t stay lit, call a professional. There may be a problem with the thermocouple or ignition system.

5. Consider the air ducts.

Is your furnace blowing hot air in some rooms but not in others? Does it seem like the airflow is weaker than you remember? Problems with your vents or ductwork are likely to blame.

Take a look at the air vents and make sure that the dampers (the little handles on the front panel) are parallel with the ductwork. This means that that dampers are fully open and allowing for maximum airflow from your furnace.

Still getting cool air from the vents? You may have leaking ducts. Cracks, holes and gaps in your ductwork allow the hot air from your furnace to escape before it reaches the vents. Not only will you have cold spots, but leaky ductwork will run up your energy bills and pull in dust and debris that then gets circulated into your home.

Over time, ducts can actually break due to the stress of fluctuating temperatures. Insulation can break down and fall into the duct space, clogging it. If a duct has collapsed or is severely obstructed, you’ll experience a reduction in airflow. Your furnace’s heat exchanger may overheat due to the lack of air, causing the burners to shut down.

If you suspect a problem with your ductwork, contact a professional who specializes in that area.

Furnace still not blowing hot air? Call in a professional.

A furnace problem won’t fix itself. Often the initial issue is simple to fix, but can lead to complicated and costly problems if put off too long.

If you’re in the Greater Chicago area, schedule your furnace service online or give us a call at (815) 455-7000. Our licensed Chicago HVAC technicians can diagnose the problem and get it resolved fast so you’re not left in the cold.

Why Do You Need a Draft Check and Combustion Analysis?

Wednesday, October 17th, 2018

Gas fired appliances like furnaces, boilers and water heaters create gases as a byproduct of the combustion process. In order for these appliances to work safely, they must be vented properly and maintain a proper draft to make sure the gases exit your home. Gas leaks, high carbon monoxide levels, and improper drafting can all be dangerous if not addressed.

Gas fired appliances like furnaces, boilers and water heaters create gases as a byproduct of the combustion process. In order for these appliances to work safely, they must be vented properly and maintain a proper draft to make sure the gases exit your home. Gas leaks, high carbon monoxide levels, and improper drafting can all be dangerous if not addressed.

These gases are made up of oxygen, carbon monoxide and carbon dioxide. A safe burn is represented by having the correct mixture of these components. An improper mixture can mean poor performance of your system and worse a safety concern. Only by using a combustion analyzer can these be checked.

Draft and combustion should be checked every year to ensure the safe and efficient operation of your gas-fired appliances. Here’s why you should make sure your annual furnace maintenance includes these two elements.

What is a draft check and why is it important?

Draft is required to draw flue gases and carbon monoxide safely out of a living area. This is generally accomplished through a chimney or vent system.

This flue draft will occur naturally in properly installed appliances unless it is affected by some outside force. Outside forces can include an attic fan, kitchen fan, the removal of a vent cap during high winds, or even a birds nest or other animal intrusion into the chimney.

If the flue draft gets interrupted or is impeded, carbon monoxide can back up in the chimney, eventually leaking or “spilling” into the home through the draft hood.

Verifying draft and checking for spillage is an important safety consideration for your furnace. Using a draft gauge to measure draft pressure inside the flue can determine:

  • If the furnace has sufficient combustion air to operate properly
  • If the flue gases can flow freely out of the home

If improper draft is found, the cause should be remedied to protect your household from carbon monoxide and to ensure proper operation of the equipment.

What is a combustion analysis and why is it critical?

Your gas furnace is manufactured to repeatedly and automatically ignite its burners throughout the winter, maintaining a comfortable temperature in your home. To accomplish this safely and efficiently, the right amount of combustion gases must be present.

A combustion analyzer measures the amount of carbon monoxide, the amount of oxygen, and the temperature of the flue gas in your furnace. This information is important for the following reasons:

  • Safety. Levels of carbon monoxide outside of the manufacturer guidelines can be dangerous.
  • If there is an imbalance or abnormality in the measurements, it helps the technician zero in on the underlying problem. Some hidden problems are impossible to diagnose without a combustion analyzer.
  • It provides an accurate measure of the efficiency of your furnace.
  • It reveals issues related to over firing and under firing. Both cause poor performance and shortened lifespan of your equipment if not corrected.

See a draft gauge and combustion analyzer at work.

This video shows how the draft gauge and combustion analyzer work to ensure your home is safer and your furnace is operating efficiently.

Make sure your annual furnace tune-up includes a draft check and combustion analysis.

Not every HVAC company doing furnace maintenance includes a combustion analysis and draft check as part of their gas furnace tune-up package. These steps are too important to skip, so always make sure you ask if they’re included before booking.

If you’re in the Greater Chicago area, schedule your heating system tune-up with Althoff Industries. Every gas furnace tune-up we perform includes a draft check and combustion analysis. We do it because it’s the only reliable way to assure the efficient and safe operation of your gas furnace.

How to Keep Your Household Safe from Furnace Carbon Monoxide Poisoning

Monday, February 12th, 2018

Most of us view our homes as inanimate objects, constructed of wood, bricks, steel, glass, and roofing materials. Few look at our houses as a representation of who we are. Literally.

Take, for example, our home’s electrical system. It serves as the “nervous system” of our houses, providing the power it needs to function efficiently. A home’s plumbing serves much like our own and even our insulation qualities are similar. Have you ever given thought to the fact that your home’s HVAC system serves as the lungs of your home?

For the most part, in extremes of heat and cold, we rely on our heating and air conditioning to provide us with clean, refreshing air. There are those few months in Crystal Lake and NW Chicago that we can shut it all off and open our windows but for the most part, we rely on our HVAC “lungs” to provide us with comfortable, safe, clean air to breathe.

There is a potential problem that can occur, however, particularly in colder weather. It is the issue of a carbon monoxide leak. A furnace carbon monoxide leak is a serious issue that takes diligence to prevent and expert technicians to diagnose and resolve.

What is Carbon Monoxide?

Carbon monoxide is a colorless, odorless flammable gas that is created when the combustion of carbon is not completed. The biggest issue with carbon monoxide is that it is toxic, causing illness, brain damage and even death can occur.

How is Carbon Monoxide Produced?

Carbon monoxide is produced by anything that burns carbon as a fuel. This includes water heaters, fireplaces, charcoal grills, kerosene, gas heaters, wood stoves, and even clothes dryers. The more energy an appliance uses, the greater the risk of the carbon monoxide it can produce.

Why is it a Dangerous?

Carbon monoxide is dangerous because takes the place of oxygen in the bloodstream and prevents oxygen from getting to the heart, brain, and organs. When exposed to carbon monoxide in large amounts, humans can be overcome in just a matter of minutes. This can cause a person to lose consciousness and ultimately suffocate in a relatively short period of time.

How Can You Protect Yourself and Your Family?

The best way to prevent yourself and family from carbon monoxide poisoning may be through the installation of carbon monoxide detectors. This will serve as a last line of defense in the event carbon monoxide levels in your home are becoming dangerous. There are steps you can take, however, to minimize your home’s carbon monoxide levels so they never reach the point of becoming dangerous.

  • Schedule an annual tune-up or maintenance check on your furnace. Most carbon monoxide issues develop over time and can be discovered and addressed by an annual maintenance check on your furnace. Many carbon monoxide issues develop gradually and can be prevented by these maintenance checks.
  • Change air filters often. As inexpensive and easy to change as air filters are, many homeowners simply forget or fail to change their air filters often enough. This can prevent fresh air from entering your furnace.  It also increases the risk of carbon monoxide production.
  • Make sure your furnace was installed correctly. It doesn’t matter whether your furnace was installed 10, 20 or 30 years ago, there may have been errors made in its installation. Poor ductwork, venting or blower installation can create carbon monoxide problems. They also may be inhibiting your furnace from operating efficiently. Standards are higher today. To make sure carbon monoxide is not an issue with your system, contact a professional.

Few things may be as frightening as the thought of a furnace carbon monoxide leak. We rely on our furnaces as a source of warmth and comfort. If it has been more than a year since you’ve had a furnace check-up, cleaning or tune-up, we would encourage you to schedule one today. Of course, we would call us at Althoff Industries. For over 50 years we’ve been keeping families safe and comfortable in NW Chicago. We would be honored to assist you.

3 Most Common Winter Furnace Repairs

Tuesday, February 6th, 2018

During winter’s blast, our furnaces work overtime to keep us comfortable without much regard to age or condition. Eventually, the weakest link in a heating system will fail, creating a need for a furnace repair. While your furnace may carry a decade or longer guarantee, some of the smaller, more susceptible parts, like those listed below, may fail prematurely.

Here are the most common furnace repairs our technicians encounter each winter.

1. Igniter Failure

Igniter failure is the single most common cause of gas furnace problems we see.

Furnace igniters replaced the pilot light systems that started gas furnaces in the past. If you remember “the pilot light going out” on your old gas furnace, you know that pilot lights were inefficient and often extinguished by drafts.

Rather than an actual standing flame, modern ignitors use electricity to heat small wires or filaments until they produce a spark to ignite the gas furnace. While igniters are safer and much more energy efficient than the old pilot lights, they’re still a common source of furnace issues.

Ignitors can malfunction with age, wear and tear. A dirty or clogged ignitor can prevent your gas furnace from igniting properly.

2. Issues With the Flame Sensor

The flame sensor is another part of the furnace ignition system that is prone to failure.

Older gas furnaces had a thermocouple, which could detect the heat put off by the pilot light. If the thermocouple determined there was no pilot light, it would prevent the flow of gas to the furnace for obvious safety reasons.

Modern furnaces use a flame sensor which, in essence, serves the same purpose. A flame sensor will prevent the flow of gas into your furnace if it detects there is no ignition source like a flame ignitor. The flame sensor must perform this task dozens if not hundreds of times per day throughout the cold weather months. Over time, the flame sensor can fail due to this great demand.

3. Problems With the High-Limit Switch

Have you noticed that your furnace will kick on minutes before warmer air begins to circulate throughout your home? This is the high-limit switch at work.

The high-limit switch has the important job of keeping the blower from powering air through your home until it’s heated sufficiently. Without a functioning high-limit switch, you’d be shivering in cold, unheated air!

This is another part of your furnace that is asked to perform thousands of times through the winter and will likely eventually fail.

When To Call An HVAC Professional

While it’s possible for experienced do-it-yourselfers to complete some of these common repairs on their own, we would caution against taking on such a task if you feel at all uncomfortable. Most modern furnaces combine electricity and gas to create combustion—two elements that require caution, know-how, and appropriate safety measures. When it comes to any furnace repair, the safety of you and your family is the primary concern.

If you’re in the Greater Chicago area, schedule your furnace service online or give us a call at (815) 455-7000. Our licensed Chicago HVAC technicians can diagnose your furnace problem and get it resolved fast so you’re not left in the cold.

HVAC Installation Day: 6 Steps our Team Takes to Ensure Success

Wednesday, January 31st, 2018

HVAC installation day for your new HVAC system is an exciting time for our team at Althoff Industries. While we try to minimize any negative impact HVAC installation day may have on you and your family, we want you to know what to expect. We also hope that the day brings a certain excitement to you, knowing you will soon have a new, more efficient HVAC system providing a more comfortable indoor environment.

There are six general steps our team takes to help ensure the successful installation of your new equipment.

  1. Loading and preparation at our shop. Installation day starts with making sure we not only have your new HVAC equipment aboard our trucks but all the tools, testing equipment, and components to complete your installation properly, safely, and efficiently. This takes making sure we have everything we need loaded before we head to your NW Chicago suburb area home.
  2. Arrival and meeting of the installation team. Once our technicians arrive, they will introduce themselves and explain a bit about the installation process and what you can expect. They will determine the best place to park vehicles as to offer as little inconvenience to you as possible.
  3. Preparation for installation. Preparation for installation includes determining the easiest and simplest pathway to the installation site(s) and making sure any flooring is covered to prevent any potential damage. Once access is determined, the real work is ready to begin.
  4. Removal and disposal of old equipment. Before we can install your new equipment, we must remove the older equipment it will be replacing. This can sometimes be a relatively simple process but in some instances where very old equipment is involved, it can be a challenge. We will remove all of the old equipment and get it ready for disposal upon our departure.
  5. Installation of new equipment. Once the old equipment is removed, we will bring your new HVAC equipment into place and begin the installation process. Even after installation, our job is not done as the HVAC system must be carefully tested and checked for safe, smooth, and efficient operation. This is done through an initial start-up and thorough monitoring and testing using specific HVAC testing equipment to monitor gasses, combustion, and airflow.
  6. We’ll explain your equipment and its operation. Once our technicians are completely satisfied your new HVAC equipment has been properly and safely installed, they will explain the operation of your equipment to you and the routine maintenance you can perform to keep it running at peak efficiency.

You should begin enjoying the benefits of your new HVAC equipment quickly through better heating and cooling of your home and lower energy bills! Our goal is to leave your home as we found it, only better!

We’ve prepared a brief video of our team preparing for an install. Enjoy the show!

You can help us on HVAC installation day by removing any items that may be in the path while we take out or bring in your equipment. For the safety of any pets as well as our technicians, please keep any animals in a separate area during the installation process. If you have a cat or dog that is sensitive to noise or strangers, you may want to consider having a friend or relative take your pet during the installation period.

Keep in mind, the installation of a new HVAC system is a major project. It is likely the largest mechanical system in your home. There will be noise and technicians will be coming in and going out of your house frequently. While we do everything we can to minimize disruptions, it is an involved process.

Thanks for choosing Althoff Industries. If you ever have any questions about your new HVAC system or would like to know more about keeping your indoor air as clean and comfortable as possible, please contact us.
