Spring Air Conditioner Maintenance Checklist and Tips for Homeowners

Friday, April 10th, 2020

When the weather starts to warm up, you want to be sure you can count on your air conditioner to do its job before it gets too hot. If you’re prepared, you can make sure you’re ready for the summer heat before the temps start climbing.

In this blog, we’ll outline the DIY air conditioner tasks that you can perform to get your system ready for summer. Of course, if you’d rather be enjoying the warm spring days instead of tinkering with your A/C unit give Althoff a call, and we can handle all your system’s annual A/C maintenance tasks for you.

Safety First

When working on home appliances, you must turn off the power before you get started. With air conditioners, you should turn off power at the thermostat and the breaker. Additionally, you’ll need a pair of safety glasses and possibly gloves. As you would expect, using a hose to spray debris out of the outside unit can get messy.

Air Conditioner Maintenance Checklist

When performing work on your air conditioning system, you’ll be working on the inside HVAC system and the outdoor unit.

1. Inspect your air filter

Your HVAC system needs to breathe to operate. If you’re getting ready to turn on your air conditioner for the first time, inspect the system’s air filter, first. Odds are that you’re probably due for a new filter.

Inspecting your air filter monthly and changing it as needed is one of the most simple and cost-effective ways to keep your system running.

Dirty air filters force your system to work harder, and over time, that extra workload can cause unnecessary wear and tear on the system. You don’t want your air conditioner to break down in the middle of a heatwave because of a clogged filter.

2. Inspect and clean out the evaporator drain

On the most basic level, your air conditioner keeps your house cool by removing heat from the air it’s circulating. Your air conditioner removes heat from the air using an evaporator coil, in which humidity condensates and collects. Eventually, water droplets from that drip from the coil to a drain pan, and finally, down the drainpipe.

Over time, this drainpipe can become clogged with mold or debris. If the drain can’t properly carry water away from the unit, then your system may shut off automatically to prevent damage, or it may leak water all over the floor.

You can easily clean out the drainpipe with a wet/dry vacuum. Simply use the vacuum to suction the drainpipe for a few minutes to ensure it’s clear of obstructions.

3. Clear debris away from your outdoor unit

Over winter and early spring, sticks, leaves and other debris have likely fallen on or around your outdoor air conditioner. Be sure to clear away any yard waste that has collected near your unit. You’ll want to clear at least a 2-foot radius around the unit to ensure it can function properly throughout the summer.

4. Complete a visual inspection of your outdoor A/C unit

Once you’ve cleared away any debris, visually inspect the outside unit for any signs of damage. Check to see if any pieces seem broken or out of place. This damage could be caused by the weather or by animals making nests in your unit over the winter.

Also, make sure the insulation is still in place around the unit’s refrigeration lines. Make sure the insulation isn’t brittle to the touch and surrounds the lines completely.

5. Clean the outside unit

Cleaning the outdoor unit is simple and only requires a few household tools and a garden hose. First, remove the cover from the unit. Then, remove any debris inside.

Next, use a garden hose with a sprayer attachment to clean the unit’s fins. From the inside of the unit, point the nozzle toward the outside to dislodge any debris that’s stuck between the fins. Once cleared, you can use a butter knife to straighten out any fins that have become bent or misshapen.

What Is a SEER Rating and Why Does It Matter?

Friday, March 6th, 2020

Are you in the market for a new HVAC system for your home? If you’re shopping for a new air conditioning system, you’ve probably had a bunch of numbers thrown at you: price, tons, voltage, or, what we will focus on today, SEER rating.

A SEER rating is used to measure the efficiency of your cooling system. Do you know what SEER rating system you need for your home? Do you know what to look for when shopping for air conditioners and reviewing SEER ratings? Do you know why SEER ratings matter?

In this article, we’ll help you understand SEER ratings and why they’re important when shopping for your new AC system.

What Is a SEER Rating?

SEER stands for Seasonal Energy Efficiency Ratio.

What the SEER rating does, is measure the cooling efficiency of an air conditioner or heat pump. Manufacturers calculate the SEER rating by dividing the cooling output for a typical cooling season by the total electric energy consumed during the same period.

Think about the SEER rating this way. Automakers almost always disclose the miles per gallon a car will receive; the SEER rating is extremely similar. Instead of thinking about gas consumed over miles traveled, think electricity consumed over cold air generated.

Typically, the SEER ratings for new residential air conditioners range from 13 to over 20. Like mpg for vehicles, a higher SEER rating indicates greater efficiency.

While the SEER rating is important to consider when purchasing an air conditioner, the highest SEER rating may not be the most suitable or the most affordable option for everyone. You’ll need to consider factors including the age of your house, the size of your house, your preferred temperature setting, and where you live.

What Does the SEER Rating Matter?

Like any other seemingly arbitrary calculation, you may be wondering, “I know higher is better, but what does the SEER rating really mean to me?”

Minimum SEER ratings

The U.S Department of Energy has established minimum SEER rating requirements for air conditioners, this rating varies based on region. If you live in the northern U.S., you can purchase air conditioners with a 13 SEER rating minimum. New systems in Illinois have to have a rating of no less than 14. For more information, refer to this brochure from Energy.gov.

Lower environmental impact

When you purchase an air conditioner with a higher SEER rating, you’re committing yourself to a lower environmental impact. Units with higher SEER ratings produce more cool air using less energy.

More efficiency equals lower utility bills

Piggybacking off the lowered environmental impact, when you use less energy, you can lower your monthly utility bill. This will be especially noticeable if you’re replacing an older air conditioner with a new one.

Older units typically have lower SEER ratings and have lost their efficiency even further as the unit has worn down over time. In some cases, the savings from a newer, more efficient AC unit can offset the cost over time.

Greater indoor comfort

Being hot and sweaty inside of your own home during a heatwave can be unbearable. Maintaining a cool indoor environment is particularly essential if you have difficulty breathing or other medical conditions. Typically, air conditioners with higher SEER ratings have more efficient motors to help keep your home at a consistent, cool temperature all summer long.

You may qualify for a rebate

If you’re replacing an older air conditioning unit, you may be able to qualify for a tax rebate, depending on where you live and what you have installed. Energystar.gov has a rebate finder that you can use to find out if you are eligible.

Improved air quality

Air conditioners with higher SEER ratings can also help maintain air quality.

There isn’t a lot of fresh air making its way into your home. Using a central AC unit allows you to continuously circulate the air through the home and filter out particles like dust and allergens. It is important to note that you need to regularly check and change your AC filters to ensure the best air quality.

Need Help Finding the Perfect Air Conditioner for Your Home?

The air conditioning experts at Althoff industries can help you determine the perfect air conditioner with the best SEER rating for your home and budget. Contact the experts at Althoff Industries today for more information or give us a call at 815-455-7000.

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

Why Does My A/C Have Ice on It in the Summer?

Thursday, September 5th, 2019

There’s nothing that’ll get you more steamed than coming home to a hot house in the summer. Imagine your surprise when you go to inspect your air conditioner, and it’s covered in ice! Each summer, this is one of the most common calls we get at Althoff Industries.

Luckily, an icy air conditioner is easy to diagnose and repair. While it may seem like you’ll have an expensive repair bill coming your way, oftentimes you simply need to make a few simple changes to prevent your air conditioner from icing over. In this article, we’ll identify the causes of most frozen air conditioners, the repair process and how to prevent your air conditioner from freezing in the future.

Warning: If you notice ice building up on your air conditioner, turn off the unit immediately. To prevent additional damage from occurring, do not turn on the air conditioner until the ice has melted and you have located the cause. If you’re unsure of the issue causing your air conditioner to freeze, contact us to schedule an appointment.

Reduced Air Flow

One of the common culprits we discover when investigating frozen air conditioners is reduced air flow. Usually, this is one of the first issues we look for, since it’s one of the easiest to correct and cheaper for homeowners to repair. Reduced air flow could be caused by any of the following:

Dirty air filter. It’s important to inspect and replace your system’s air filter regularly. It’s a relatively inexpensive home ownership task, but you can end up with a hefty repair bill if you don’t keep up with the maintenance. When you have a dirty air filter, your system has to work extra hard to move the air through your home. This causes your air conditioner to work overtime, which may lead to ice buildup on the compressor, among other issues.
Too many closed air registers. You might think you’re doing yourself a favor by closing air registers and saving yourself a few dollars on your summer cooling bill. Unfortunately, when you close too many registers, you reduce the amount of airflow below the amount required to optimally run your home’s cooling system, which can cause the condenser to freeze. Make sure at least 75% of your air registers are open at all times.
Damaged air ducts. Depending on where they’re located, in a wall, basement or even closet, your system air ducts can take a beating when you’re moving heavy equipment or doing home repairs. If you end up damaging a duct, you can decrease the airflow.
Decreased fan speed. Over time, your system can get worn down, and your fan speed can decrease. On the other hand, your system’s fan speed may not have been set fast enough to begin with. If you’ve tried all other air flow repair methods without any luck, a technician can help you determine if the fan speed is freezing your air conditioner.

Faulty Thermostat

If your system is having trouble regulating the temperature, you waste money, energy, and odds are, your air conditioner is freezing over. When your system can’t properly regulate temperature, it’s running constantly, even when it’s cold out at night. As your condenser works overtime, the coils can build up condensation and eventually freeze over. If you notice your system is running even when it’s cool outside, your thermostat could be the culprit. A professional can help you test your thermostat and pinpoint the issue.

Drainage Problems

In addition to keeping your house cool, your air conditioner extracts humidity from the air to make your home’s air more comfortable. This excess moisture needs somewhere to go if it’s not in the air. Your air conditioning system should have a drainage pipe attached that carries moisture away from the unit. If this pipe becomes blocked, the water can get stuck in the unit and freeze. Ensure your system drain is clear and removing moisture efficiently.

Similar drainage problems can occur if you have a window unit that’s freezing up. To drain properly, window unit air conditioners must be tilted at a slight angle out of the window to allow water to drain. If your window unit is freezing up, ensure the air conditioner is tilted according to the manufacturer’s installation instructions, and check that no debris are blocking the drainage hole.

Low Refrigerant

You might have never have guessed, but having low refrigerant can actually make your evaporator coil freeze. Seems weird, right? If you don’t have the proper amount of refrigerant in your A/C system, it has to work harder to cool your home. When your unit is working too hard, icing is likely to occur. Typically, low refrigerant is a sign of a leak in the system. You can usually identify a leak by listening for a hissing or gurgling sound coming from the condenser. If you suspect a leak, it’s time to call a professional to help repair the leak and recharge the system with refrigerant.

Is Your Air Conditioner Putting a Freeze on Your Summer Fun?

The experts at Althoff Industries can help you identify why your air conditioner is freezing and repair the issue. Don’t let a frozen air conditioner prevent you from staying cool during the summer, give us a call at 815-900-5002, and schedule your appointment today!

My A/C Is Running but Not Blowing Cold Air

Monday, July 1st, 2019

Summer is in full swing and, on really hot days, all you want to do when you get home from a long day is to enjoy some cool air conditioning. Nothing kills this excitement more in the warm summer months than entering your home only to realize that your A/C is not blowing cold air. Unfortunately, an A/C is not fail-proof and they can quit blowing cool air for a variety of reasons. We have listed some of these reasons below so you can have an idea of why your A/C quit working and how you can resolve the issue.

Reasons Why Your A/C is Running but Not Blowing Cold Air

1. Your Thermostat Is Set Incorrectly

Sometimes an A/C doesn’t blow cold air simply because your thermostat settings need to be adjusted. Luckily, this is a pretty easy issue to resolve on your own. Some people think that leaving their A/C running all day is the best way to keep their home cool, but it is actually best to set your fan to AUTO, this will ensure that your air conditioner is running only when it is actually cooling the air. Changing this setting will help save money on energy bills, ensure that you don’t wear out your A/C too quickly, and keep your home cool.

2. Your Air Filter Is Dirty

Having a dirty air filter can inhibit airflow which could definitely be a reason that your A/C isn’t blowing cool air. Take out your air filter and see if there is any debris. If you do notice that the air filter is dirty, swap it out for a new one and get in the habit of changing it out every month.

A great way to ensure that your air filter is clean and your A/C works all summer long, we suggest having professional regularly scheduled maintenance.

3. Your Outside Unit Is Dirty

In the same vein as point number two, having an outside unit that is covered in dirt, dust, and other debris could also be inhibiting cool air from making its way into your home.

Air conditioners work when the inside unit (called an evaporator) absorbs heat from the air and then transfers that heat to the outside unit (called the condenser). The condenser can’t properly dissipate heat if it’s dirty or crowded with debris.

You can resolve this issue by spraying the outside unit with a garden hose on a gentle setting and removing weeds and overgrowth around the unit.

4. Refrigerant Leak

Refrigerant is the liquid that absorbs the heat from the air. When you don’t have enough refrigerant, your A/C can’t absorb enough heat to cool the air. Refrigerant leaks are fairly common and can definitely be the reason why your A/C isn’t blowing cold air.

Signs you have a refrigerant leak include:

Ice buildup on the outside unit and line
Bubbling or hissing noises
Your A/C doesn’t cool the home on hot days but works fine on cool days and at night

If you see these signs, turn off your A/C immediately and call a professional. Refrigerant chemicals are very dangerous and need to be handled by the experts.

5. Air Duct Leaks

Over time, the air ducts that move air conditioning through your home may become loose or their seal may be compromised. This means that air is escaping erratically which makes it hard to keep your home at the temperature you want. You will need to have a professional come out and evaluate your air ducts to ensure that they are not leaking cool air and make repairs as needed.

6. A Bad Compressor

The compressor is one of the most important parts of the A/C system and pushes the refrigerant through the unit. If your compressor isn’t working properly, your A/C cannot work. Compressors need to be evaluated by a professional and replaced if they appear worn out or defective. Unfortunately, compressors are expensive unless you have a warranty. Chances are if your compressor is bad, you’ll probably need to replace an entire outside unit.

7. Dirty Evaporator Coils

An evaporator coil is the part of the A/C system where the refrigerant absorbs heat. Over time, the evaporator coils get dirty and affect the performance of your A/C and make it harder to remove warm air.

Dirty evaporator coils can lead to your A/C overheating and potentially shutting off completely. Evaporator coils should be evaluated and cleaned by a professional to ensure that they are in good condition.

Schedule an Appointment and Stay Cool All Summer Long

If your A/C is not blowing cold air, contact our licensed Chicago HVAC technicians. They can help troubleshoot the problem so you can cool down and relax again. Contact us at 815-455-7000 to schedule.

5 Air Conditioning Noises and Their Causes

Thursday, June 13th, 2019

Summertime—it’s sunshine, warm breezes, barbecues and the gentle hum of air conditioners keeping houses cool throughout the neighborhood. In a split second, that gentle hum can turn into an unnerving hissing, banging or screeching. While all air conditioners make noise, it’s important to be able to recognize which noises are normal, and which noises require a professional inspection.

1. Hissing

Uh oh! More than likely, you’ve sprung a leak. Usually, a hissing sound indicates that your air conditioner is leaking refrigerant. In some cases, there’s a small opening in one of the refrigerant lines. In others, there may be an internal valve leak.

If the hissing is really loud and accompanied by squealing or screeching from the compressor, you need to turn off your air conditioner immediately. This indicates that there is too much pressure in the compressor, which could lead to a costly repair bill if you don’t act soon.

2. Screeching

One of the most startling noises is generally one of the easiest to diagnose. In newer direct-drive A/C units, you can trace a screeching noise to a shot bearing in the fan motor. Usually, you’ll have to replace the fan motor to get the noise to stop. In older A/C units, the screech could be coming from the belt that connects the motor to the blower. Belts gradually wear down, and you need to replace them from time to time.

3. Banging

A loud banging or rattling can mean that there’s a loose part somewhere in your A/C unit. Before more damage occurs, you’ll want to shut of the air conditioner as soon as you hear the noise. Is the noise louder outside of your house or inside of it? If it’s outside, one of the fan blades could have come loose in the compressor. If the noise is louder inside, your blower fan might be causing the racket.

4. Clicking

Hearing a clicking sound when the air conditioner kicks on is common and completely normal. That click is how your thermostat communicates with the unit. However, when it’s on, your A/C shouldn’t be ticking like a clock.

Like banging noises, clicking often comes from a loose or damaged part that’s hitting against something that it normally wouldn’t. An occasional clicking noise could indicate that there’s something stuck in one of the airways. On the other hand, if the clicking is constantly coming from your thermostat, there could be an issue with the circuit board.

5. Buzzing

A couple of issues could make your air conditioning unit buzz, like a swarm of hornets building a nest in your outside unit. If you can rule out pests, the buzzing could be coming from loose parts rubbing together, or your air conditioner might have frozen up. If you see a buildup of frost and ice on the unit, a professional can help you determine the cause. Finally, listen to hear if the buzzing sound is coming from the unit’s power source. The A/C could be overloading your circuit panel, which will require a professional evaluation.

If your air conditioner is making a noise that it shouldn’t, call Althoff.

Ignoring the problem could cause damage to your unit that then requires more extensive repairs. Have one of our licensed Chicago HVAC technicians check out the sound now and get peace of mind. Contact us at 800-225-2443 to schedule.

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?

Top 4 Reasons Your Air Conditioner Isn’t Working

Tuesday, July 3rd, 2018

Oh, fantastic. You’re sweltering on a hot day and no matter how low you set the thermostat, your air conditioning system just can’t seem to cool the house. Or maybe you feel warm-ish air coming out of the vents instead of nice cold air. What could be going on?

There are many possible reasons why your air conditioner isn’t working, but here are the four most likely ones.

1. Refrigerant leak

When most people think about their air conditioner, they think that cool air is being created. In actuality, the job of the air conditioning system is to collect heat from inside the home, move it outdoors and release it.

Have you ever driven past a construction site and seen a line of dump trucks carrying dirt away as they clear the land? One by one the trucks are loaded, filled and then driven away to be dumped at another location.

In the same way that a dump truck is used to haul dirt from one place to another, refrigerant is used in the air conditioning system as the container to move heat. Each pound of refrigerant is designed to carry a certain amount of heat outside and release it. A system that doesn’t have enough refrigerant will not be able to cool the house properly or at all.

Symptoms of low refrigerant are:

Blowing warm air
Poor performance (“I have my stat set at 70 and I can’t get the house below 75!”)
Icing on the refrigerant line

If you previously had enough refrigerant and now the level has dropped, there is a leak that must be addressed.

2. Failed capacitor

Your air conditioning unit requires more energy to start up than is available through your home’s wiring. A capacitor is added to the circuit to give the unit an electrical jumpstart. Your system contains several capacitors that help start the compressor, outdoor fan motor, and blower motor inside. The most common capacitor to fail is the compressor motor run capacitor.

Capacitor failure is very common but inexpensive and quick to repair. Since it is a very common repair, service technicians stock these on their trucks. Most capacitors fail simply due to age. The life expectancy can vary, but the typical rating is about 5-7 years.

3. Failed contactor

A contactor is a small device that controls the flow of electricity to your air conditioner’s components. Think of a contactor like a drawbridge. When the drawbridge is down, cars can drive freely over the bridge to the other side. When the bridge is up, cars have to wait until it is lowered again.

Contactors work in the same way but instead of controlling traffic, they control the flow of electricity. When your air conditioner is not in a cooling cycle, the contactors are in the “up” position blocking the flow of electricity. When the thermostat wants to start a cooling cycle, a small voltage is sent to the contactors that tells them to lower into the “down” position. Contactors will stay in the down position until the thermostat is satisfied.

Contactors typically fail due to age and normal wear and tear. Like the capacitors, failure on this component is very common but can be repaired quickly.

4. Lack of maintenance

Probably the most common reason for air conditioner failure is lack of maintenance. Like any piece of machinery, your furnace and air conditioning system requires maintenance.

Here are some common consequences of poor maintenance that can leave you without cold air or with a higher-than-normal cooling bill:

Plugged filters

As air from your home blows across the evaporator coil, heat is absorbed by refrigerant and delivered outside. If the filter is plugged and air flow is restricted, it will cause the coil to freeze and leave you without air conditioning.

Plugged condensate drain lines

In addition to cooling, your air conditioner removes humidity from the air. This water is removed through a small drain pipe and deposited in a floor drain or outside. Left unmaintained, over time this drain can form a clog. The clogged drain can cause the excess water to backup and cause damage to your furnace or property.

Plugged condenser coils

Heat removed from the house is taken outside and released. If the outdoor coils are not maintained and kept clean, your system will be very inefficient. The unit’s inability to release heat will cause the system to run much longer and do a poor job of cooling the home.

Let the pros at Althoff take care of your AC system before there’s a problem.

If it’s been awhile since you’ve had your AC system checked out or maintained, do yourself a favor: Get it done before you’re left without cold air on a hot day.

The Difference Between Commercial and Residential HVAC Services for your Chicago Property

Wednesday, June 13th, 2018

Do you know the differences between residential HVAC and commercial HVAC? Knowing the differences can help you choose the right contractor for your routine maintenance, repairs and HVAC replacements.

Residential HVAC

Residential HVAC contractors repair, replace and maintain central air conditioning and heating units on single-family homes. These units often contain an outdoor condenser that is located near an outside wall and is responsible for dissipating heat and an indoor unit that is responsible for filtering the air and pushing the cool air through the air ducts.

Commercial HVAC

Commercial HVAC units are much larger than residential HVAC units because they are needed to cool much larger spaces, and they must be repaired, maintained and installed by commercial HVAC contractors that are familiar with large systems. These units are typically located on rooftops, and depending on the size of the building, more than one rooftop unit may be installed. Unlike the residential HVAC system, the commercial rooftop unit is an all-in-one unit that contains everything needed to heat and cool the building. The only items located inside the commercial or large multi-story building are the air ducts and the thermostats.

The Primary Differences Between Commercial and Residential HVAC Units

There are three main differences between commercial and residential HVAC units, including the size of the units, the location and the expansion options.

1. Size and Power of the Unit

Commercial HVAC units are often much larger and much more powerful than their residential counterparts. This is because they must be able to heat, cool and dehumidify the occupied spaces of the building, which could range in size from 5,000 square feet to more than 100,000 square feet. By contrast, single-family residential homes average about 2,000 square feet, and their heating and cooling functions are often separate with the cooling functions being controlled by the central air conditioner and the heating functions controlled by a furnace or heat pump.

2. Location of the HVAC Unit

Because commercial HVAC units are so large, they are often located on rooftops to keep the bulky and oftentimes unsightly equipment out of view of the public. Rooftops also offer lots of room, which means multiple rooftop units can be easily connected together to add heating and cooling power. Residential HVAC units are rarely located on roofs. Instead, the inside parts of the unit are typically located inside an HVAC closet, and the outdoor unit is typically located near an exterior wall and connected to the interior unit via copper piping and electrical wiring.

3. Expansion Options

Residential HVAC units are not typically expandable. Instead, the residential HVAC technician chooses the right sized unit by calculated the occupied square feet, number of doors and windows and ceiling heights. Once the area to be cooled is known, the right sized unit can be purchased and installed. If expansions are performed on the house and additional cooling power is needed, the unit has to be replaced with a large HVAC system.

By contrast, commercial HVAC units are designed to be expandable. If the commercial building undergoes a renovation that increases the occupied square footage, additional rooftop units can be connected to the existing units in order to provide more heating and cooling power.

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.

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.
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.
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.
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.
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.
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.
