Whole House Humidifier Pros vs. Cons

January 24th, 2018

Many view home heating from a pretty straight-forward standpoint. If they are comfortable, their thermostat is set correctly. If they are not comfortable, the thermostat is set too low or too high. Of course, when multiple family members are involved, this can create quite a challenging situation that is often resolved by the person who pays the utility bills. There is, however, another major factor in the comfort of your home. It is humidity.

We are all familiar with humidity during our Chicago summers but humidity plays a significant role in comfort during our winters in the Crystal Lake area as well.

Humidified air can feel much warmer, cozy, and comfortable. Dry air can lead to static electricity, premature drying of wood cabinets, flooring and furniture, and even more frequent illness. Families are often surprised at the amazing impact a properly humidified home can have on their comfort, especially during the cold weather months. They can also see energy saving benefits.

Some are familiar with smaller, single-room humidifiers that can help humidify a small space. These portable humidifiers can offer some relief but if lack of humidity is an issue for the whole house, and having an impact on you and your home’s comfort you may want to consider a whole house humidifier.

What is a Whole House Humidifier?

A whole house humidifier is a device that works with your furnace to add moisture into the air in your home. This moisture is provided through your home’s plumbing and is heated and dispersed into your home through your furnace and ductwork. A whole house humidifier is sometimes referred to as a furnace humidifier and provides air that simply feels warmer.

Pros and Cons

If you experience dryer air in your home, you can find relief from either a portable or whole house humidifier. Portable humidifiers only impact a small area and the water tank the humidifier uses must be refilled frequently. A whole house humidifier will improve the comfort of your entire home and because it is directly fed moisture through your plumbing, refilling a tank is unnecessary.

The downsides to a whole house humidifier are few but significant. First, a whole house or furnace humidifier can be a sizeable investment. Many, however, find that the air is warmer in their home following installation, allowing them to operate their furnace at a lower temperature. This, of course, can translate into long-term energy savings, which can help offset the original investment.

The other con to the installation of a whole house humidifier is that it can be a fairly complex task. It should be handled by a professional. A furnace humidifier must be installed correctly to provide full value. Beyond exceptional comfort, families using a whole house humidifier experience less illness and annoying static shocks.

What To Do Before Calling for Emergency Furnace Repair

January 10th, 2018

It’s a frigid winter day and you wake up to a cold house. You soon discover that the heater isn’t working! Your first thought is to call for emergency furnace repair.

Before you grab your phone, you can take a few simple steps to see if you may be able to resolve the issue on your own. This may help correct the problem quicker and without the expense of a potentially unnecessary emergency furnace repair call.

5 Quick Furnace Troubleshooting Tips

1. Check your thermostat.

Make sure that the thermostat is on and set to “heat.” This sounds obvious, but you wouldn’t believe how many service calls happen because the homeowner didn’t know that someone (like a guest or child) adjusted the settings!
If your thermostat has a fan setting, set it to “auto” instead of “on.” Otherwise, the fan may blow continually even when the air isn’t being heated.
If the room temperature is lower than the thermostat setting, try adjusting the setting up a few degrees to see if the furnace kicks in.

2. Make sure you have power to the furnace.

Even if you have a gas furnace, an interruption in electric power will interrupt your furnace from producing heat. You may have a circuit breaker that has tripped.

If that’s the case, you can reset it by turning the circuit all the way off and then on again. If the circuit immediately breaks again, call a professional.

3. Check your air filter.

An air filter that is extremely clogged will not allow the air to be heated properly. It may cause your furnace to overheat and shut down.

Remove the filter and hold it against the light. Can’t see any light through it? Replace it. We recommend checking your furnace filter every month and replacing as needed.

4. If you have a gas furnace, make sure the gas supply is on.

If you’ve had any repairs done lately, someone may have shut off the gas supply valve and then forgot to turn it back on. Or, the gas company may have shut down the gas lines for maintenance. A quick check with the gas company is a good idea if you think this may be the case.

Check the gas valve at the gas company’s meter.
Check the gas valve on your furnace. Your furnace’s gas valve is on when the handle is inline (parallel) with the pipe. If it’s off, the handle will be perpendicular to the pipe.

If you smell gas, turn off the supply and immediately call a professional.

5. Check the ignition source or pilot light.

Most modern furnaces have an igniter coupled with a flame sensor rather than a physical pilot light. Both of these can wear out and require repair. In fact, ignitor and flame sensor problems are some of the most common furnace repairs we encounter.

If you have an older furnace, your unit may have a physical pilot light. A draft or interruption in gas service can cause the pilot light to go out. If your pilot light is out, and you’ve already confirmed that you have a safe gas supply, try relighting it according to your owner’s manual. (This is usually done with a fireplace match or long barbeque-style lighter.)

If you’re not comfortable with this, or the pilot light won’t stay lit, call a technician.

4 Furnace Facts to Know When Calling for Repair

If the above steps do not resolve your issue, it’s time to call for furnace repair. Gathering the following information will help your technician resolve the issue more promptly.

Make note of your furnace brand and model number.
Make note of your furnace’s approximate age.
Write down the steps you took in trying to determine the problem.
Be sure to let the repair company know if they have done previous work for you.

Share the above information when you’re on the phone with the customer service representative when scheduling your service call.

At Althoff Industries, we appreciate having this information so our technician has a head start on the specific problem. He or she can make sure to have the appropriate part or parts to resolve the problem on the initial call.

Althoff HVAC Trucks: Fully Stocked to Finish Residential Service Jobs

January 3rd, 2018

Those who live and work in the Crystal Lake, Northwest Chicago area, and its suburbs have likely seen our Althoff Industries service trucks on the area roadways. You may not, however, have given much thought to what all is contained in these vehicles.

It helps to understand that for our technicians, these trucks tend to serve as their offices on wheels. As such, they need to contain the parts and tools that we use most often. This better allows us to complete a repair on the first call properly. It also saves us, and you, time and money.

Of course, with so many brands, types, sizes, and configurations of heating and air conditioning equipment, this leads to quite a collection of parts and tools. Is it always pretty and well-organized in the back of our service trucks? Not very often. But through the years, however, we have become quite adept at making sure our trucks are equipped to handle the most common HVAC and plumbing related problems on an initial call. Let’s take a closer look at what you may typically find in an Althoff HVAC residential repair truck.

Hand and Power Tools

Of course, one of the most critical factors in residential HVAC repair is having the right tool for the right job. This means a variety of both common and specialized hand and power tools that range from hammers and pliers to sheet metal cutting tools and soldering equipment.

Gauges, Diagnostic and Measuring Equipment

At Althoff Industries, our primary concern is that of the safety of your family. This makes it necessary that we have a variety of gauges and measuring equipment to help us properly diagnose any potentially dangerous conditions. These devices include equipment like a combustion analyzer, draft gauge, manometer, and more. Humidity and temperature gauges also help us in determining HVAC related issues.

Various Nuts, Bolts, and Small Parts

The back of one of our residential HVAC repair trucks will have a variety of nuts, bolts, screws, and small parts to help technicians complete their tasks. This will also include a variety of sealers, electrical tapes, duct tape, and PVC and sheet metal parts.

Parts that Commonly Fail

Some HVAC parts are more prone to failure than others. These include relays, transformers, circuit boards, capacitors, thermostats, thermocouples, blower motors, igniters, and more. Our trucks contain a variety of these parts including replacement hoses and valves, wiring, switches, connectors, breakers, and others.

The Most Important Part

Our trucks contain refrigerant, refrigerant reclaim jugs, flush kits, glycol and glycol pumps, and so much more. But it is what you don’t see in the back of our HVAC contractor truck that is perhaps most important. That is the knowledge, training, and experience of our Althoff Industries technicians.

When you contact us for a service call, you likely want that call completed as efficiently and quickly as possible. A properly equipped and stocked truck can help us better accomplish that.

Keeping our trucks properly stocked and outfitted with the latest tools is part of the cost of doing business. So is properly maintaining our vehicles so they are ready to go when you need us. Whether your furnace decides to give out during the coldest day of the winter or your AC fails in the mid-summer heat, you can count on the team at Althoff Industries to be prepared. When you experience HVAC issues, we invite you to contact us, at Althoff Industries.

10 Tips to Save on Illinois Energy Costs this Winter

December 27th, 2017

Odds are you and your neighbors are looking for ways to save on heating costs this winter. You’ll be glad to know you can cut Illinois energy costs without expensive remodeling or the purchase of brand new HVAC equipment. Here are some relatively simple, low-cost ways you can cut your heating costs on your Illinois energy bill this winter.

10 Tips to Save on Heating Costs

Check the height of your exterior door thresholds. You should not be able to see any light between the bottom of your exterior doors and the bottom threshold under the door. If you can, you are giving warm air an easy way to get out and drafty cold air an easy entry point. Cure this issue by raising the threshold height or by adding a door sweep to the bottom of the door. You can also use a variety of tubular, stuffed draft stoppers that you can lay across the bottom of your door once you are inside.
Use a portable heater to help heat the room in which your family spends the most time. Most of us heat our entire home to the temperature we are most comfortable, yet many of the rooms are empty. Consider a space heater or portable heaters for the rooms you use most. This will keep you cozy without wasting money overheating rooms that aren’t being used.
Check your ductwork for leaks. The sheet metal pieces of your ductwork can develop leaks and creases over-time. This prevents all of the heated air from getting to the specified heating vents. You can save on heating costs by inspecting ductwork where you can and sealing any seam that appears loose with duct tape.
Buy a programmable thermostat. You will likely save heating costs by purchasing a thermostat that you can program to comfortable temperatures when you are at home and save energy when you are not. Thermostats are inexpensive, usually under $50.
Buy heavier, insulated curtains to help keep your home warm. Heavier blinds, curtains, and shades can do wonders keeping out the cold, especially if you have older windows. At the same time, you can use windows that face the sun to “capture” natural sunlight to help warm your home during daylight.
Check weatherstripping around windows and doors. It may seem like last year when you replaced weatherstripping around your doors and windows but it may be much longer. Weatherstripping loses its ability to be effective after several years and replacing it can help you save on heating bills.
Caulk or use expanding liquid foam to insulate where pipes and vents enter your home. Anywhere there is a breach into your home where cold air or drafts can enter is likely costing you money. Look under your sinks, around your dryer’s vent, and take electrical socket covers off to see where you can save on heating bills.
Install clear plastic film over windows. Today’s modern, plastic fill products are easy to install and are hardly noticeable once installed. Using a simple blower hair dryer will stretch the film to be virtually invisible. The impact they can have to cut heating costs can be surprising.
Reverse ceiling fans. You may know that heat rises but did you know that your ceiling fan can help recirculate that warm air back down from the ceiling to save on heating bills? There is likely a switch on your fan that can reverse the direction of the blades to counterclockwise in the winter, helping you use energy more efficiently.
Change your furnace air filters. We say this so often but it is absolutely critical if you want to save on heating costs. Furnace filters are inexpensive and easy to change and should be step number one if you want to cut heating costs.

Of course, if you are still frustrated with your heating bills, we invite you to call the indoor air experts at Althoff Industries. We’ve been helping keep Chicago and Illinois area homeowners comfortable for over 50 years.

Should I Repair or Replace My Furnace?

December 20th, 2017

Regular maintenance goes a long way in extending the life of your furnace. There are points, however, when even a well-maintained furnace may need replacing. Like any other appliance, furnaces don’t go on running forever.

Here are signs that it may be time to replace your furnace.

5 Furnace Replacement Signs

1. Your furnace is old enough to drive.

Once your furnace reaches 15 years of age, it’s beginning to live on borrowed time.

Even if your 15-year-old furnace seems to be operating properly, you may notice escalating heating bills. Once you start repairing an aging furnace, those repairs often become more regular, extensive and expensive.

That’s not to say that a well-maintained furnace may not last five or ten years longer. Still, the 15-year lifespan serves as a guidepost to prepare for repairs or replacement. Like an aging car in need of constant repair, there will be a time you need to decide when to draw the line and replace it.

2. Your home doesn’t feel as comfortable as it once was.

Are you reaching for your coat even when you’re indoors? Are the kids bundling up for dinner? Are you constantly adjusting the thermostat because your living room is warm but the bedroom feels like the North Pole?

Poor and uneven heating are common symptoms of furnace problems. If your furnace is still young, it may only need a simple furnace filter change or other routine maintenance.

If you have an aging furnace, however, it may be time to budget for a replacement.

3. Your furnace is becoming the soundtrack of winter in your home.

A well-operating, efficient furnace should be almost imperceptible when it’s running. At the very least, it shouldn’t attract attention to itself.

Rattling, screeching, clamoring, popping, and rumbling noises are likely signs your furnace has an issue and needs professional attention.

If the furnace has reached the 15-year milestone, these sounds may be a cry for a furnace replacement.

4. Your heating bills are climbing.

If your rates have stayed steady and it’s not an extraordinarily cold winter—yet you still notice higher energy bills—your furnace may be picking your pocket and it needs to go.

Higher energy bills are a common motivator for furnace replacement. This can ultimately prove a prudent decision as opposed to repair. If your bills are climbing now because of an inefficient furnace, they aren’t going to suddenly become cheaper.

5. Your house has never been comfortable in the winter.

If your home has never quite seemed comfortable during the winter months, the problem could be drafty windows or poor insulation. But, it could also mean your furnace was never properly sized or installed. In the Greater Chicago area, contact Althoff Industries and we’ll help you determine what can be done or if a furnace replacement will solve your problem.

Repair or Replace?

Even when a furnace replacement is necessary, it’s not all bad news. A new furnace will operate quietly and more efficiently. Many of our customers experience savings so significant, they tell us they wish they’d replaced their furnace sooner!

If you suspect your furnace is reaching retirement age, call Althoff Industries at (815) 455-7000. We serve customers throughout the Greater Chicago area, and can help you determine whether your furnace is worth saving or replacing.

A Clog Free Condensate Line Keeps Your Property Safe from Water Damage

December 13th, 2017

Next to the safety of your family, the highest priority of the team at Althoff Industries is to make sure your property is protected from damage from your HVAC system. To help ensure that, one of the routine maintenance tasks we perform on every clean and check and repair is to make sure the condensate line is clear.

What is the purpose of a condensate line or drain, how does it get clogged, and what can be the result if it does clog?

The Role of a Condensate Line

Many homeowners don’t understand that their air conditioner not only cools the air it treats but it dehumidifies it as well. On a humid day in Chicago, as much as five to 10 gallons of water can be removed from the air. This water is funneled into a drip pan and then removed through the condensate line to the outside of your house or to a drain inside the home.

How Does a Condensate Line Become Clogged?

Even if you are diligent in keeping air filters clean and even if you have a whole house air cleaner, dust and dirt can still collect in and around your HVAC system. The moisture that is removed from the air can serve as a “dust magnet”, attracting dust and dirt particles into the drip pan and eventually the condensate drain. If not cleaned, this can clog the condensate line.

What are the Potential Ramifications of a Clogged Condensate Line?

If the condensate drain is clogged, the water in the drip pan has nowhere to go and will overflow. This can cause damage to your HVAC equipment, flooring, and walls. If not promptly corrected, it can even lead to mold, which can be expensive to remediate. You are far better off having your condensate line cleaned with your annual furnace maintenance and HVAC check.

Cleaning the condensate line is a relatively simple task, yet some HVAC companies won’t perform a condensate drain cleaning unless a clog is apparent. At Althoff Industries, we understand that clogs usually don’t just occur overnight, they develop over time. By cleaning the condensate line on every visit, we are conducting proactive maintenance to prevent a potential problem in the future. We’ve created a brief video explaining condensate drain cleaning if you’d like to learn more.

If you have any questions about your HVAC equipment or would like to schedule an annual furnace maintenance clean and check, we invite you to give us a call. Next to the safety of you and your family, protecting your home is our next highest priority.

Why These 3 Things are Important to HVAC Combustion

December 6th, 2017

You don’t have to be a mechanic to own or operate a vehicle. Some knowledge, however, can be valuable when encountering an issue or even when purchasing a car. Likewise, you don’t have to be an HVAC technician to own a home with a furnace but having some basic knowledge can help keep you safe and help you make better decisions when it comes time for repairs or an HVAC replacement.

Homeowners, for example, should understand the basics and importance of combustion. If you have any gas appliance, whether it is a water heater or furnace, combustion is taking place in your home on a regular basis. You certainly want it to occur efficiently. It is critical that it takes place safely. Knowing how combustion takes place and why a combustion analysis with draft gauge measurement is so important can be helpful.

The Three Components of Combustion

The three components to maintain combustion are fuel, heat, and oxygen. If any one of these is insufficient, combustion won’t occur.

Fuel – As it relates to your natural gas furnace, the fuel is the natural gas itself. We tend to take the supply of gas for granted but corrosion and debris impede the supply of fuel to your furnace.
Heat – The heat to your furnace is generally supplied by the igniter on your furnace. Your thermostat controls when the igniter will supply heat to the natural gas based on the temperature it is set at. If the ignition source fails, safety features will keep gas from flowing into the combustion chamber.
Oxygen – Air that is supplied to your furnace or water heater provides the necessary oxygen to complete the combustion triangle. High-efficiency furnaces will have air pumped directly into the combustion chamber from the outside. Less efficient furnaces will draw in air through louvers in the furnace cabinet. If this air is restricted the furnace can’t operate efficiently and may not ignite at all.

Along with the three components of combustion, draft is also critical to the safe and efficient operation of any gas appliance. That is because, after combustion, carbon monoxide and flue gasses need to be removed from the home. The proper draft is important in removing these gasses. This is why our Althoff HVAV technicians perform a draft check and combustion analysis on each service call.

Our technicians use three tools to ensure the safe operation of your HVAC system. A recent short video we created helps demonstrate the importance of these tools as a way to diagnose your equipment.

Your HVAC equipment may be the largest mechanical component of your home. Make sure it is operating safely and efficiently. For a furnace clean and check, professional repairs, and for recommendations on the most efficient equipment to choose for your application, we invite you to contact the professionals at Althoff Industries. We are here to keep you safe and comfortable.

The Best Overall Furnace Filter for Your Residential HVAC System

November 22nd, 2017

There are more choices than ever when choosing a furnace air filter for your home. How do you know what is the best furnace filter for you?

Furnace Filter Purpose

It can help to have a basic understanding of the purpose of an air filter. A furnace air filter should remove larger particulate matter from the air flowing into your furnace, keeping it from accumulating in your HVAC system and being redistributed into your home. It also should facilitate proper airflow through your HVAC system and into your home. It seems simple enough, so why the confusion?

The sheer number of choices in furnace filters complicates the matter for many. Today’s furnace filters range from just a few dollars up to $50 or more. Some feel that more expensive filters must be better. That is simply not the case. Some consumers are impacted by the clever marketing of some companies producing filters that promise fresher, cleaner, healthier air. The challenge is that some of these filters restrict airflow to the point of causing inefficiencies, potentially overworking your furnace and perhaps even causing mechanical problems.

Standard Air Filter, the Best?

So what’s a homeowner to do? The reality is for the vast majority, the inexpensive, fiberglass, disposable furnace filters will perform fine, especially when replaced frequently. These filters range from 1-4 on the MERV scale, removing 80% of the particles that are 50 microns and larger while collecting 25% of the particles within the 3 to 10-micron range. Pleated filters may improve filtration by 15-20% over the spun fiberglass variety but they can cost four to five times as much and inhibit airflow.

What about Air Filters and Allergies?

Now, if someone in your family suffers from severe allergies or is sensitive to dust, you may want a filter that can remove smaller particles without negatively impacting airflow. At Althoff Industries, we offer such filters that can be compatible with your system. These thicker air filters we recommend will upgrade your indoor air quality, while minimizing negative impact on air flow. Our professionals will measure the airflow to ensure your equipment is being protected while improving filtration. This is not something you should guess at on your own, however.

It’s a Balancing Act

The appropriate air filter strikes the balance between protecting equipment, facilitating airflow, and keeping your indoor air quality in check. Keep in mind, the main function of your furnace is to heat your home, not clean the air. Asking it to perform the added task of an air cleaner with an inappropriate filter may ultimately cause mechanical issues.

If you have questions on how to improve your indoor air quality without damaging your HVAC system or would like to schedule a thorough clean and check of your system for the winter, contact the professionals at Althoff Industries.

How to Choose the Right Air Filter for Your HVAC Equipment

November 15th, 2017

If you find yourself having to set your thermostat at unusually high or low temperatures just to stay comfortable, your problem may be poor air flow. Poor air flow may be caused by too much friction in your HVAC system or too much turbulence. One of the most significant causes of friction in an HVAC system is the air filter.

How is an Air Filter Related to the Comfort of a Home?

Even a clean HVAC air filter will offer some friction to the air flow in a furnace. If a filter is dirty or too restrictive in its design, it will not allow a sufficient airflow through your system and into the rooms it serves. This can lead to your system overworking and struggling to provide the comfort you desire. It will also increase the inefficiency of your unit. While we find that more and more homeowners understand the importance of changing filters, many still fail to remember to do it or are purchasing filters that are too restrictive for their systems to operate properly.

How Do You Determine the Best Filter for You?

HVAC filters are rated based on a minimum efficiency reporting value (MERV). This is a 1-16 scale but most home filters fall within the 4 to 12 range. The higher the rating, the smaller the particles are that can be trapped by the filter. Higher ratings also make filters more restrictive to air flow and generally are more expensive.

Selecting the right filter for you and your family will depend on the balance you place on comfort, expense, clean indoor air quality, and furnace efficiency. Most homeowners can usually settle in the 6-8 MERV range without negatively impacting air flow. The 6-8 range filters are also still affordable.

Before You Switch to a High-Efficiency Furnace Filter

A high-efficiency HVAC air filter can remove up to 99% of particulate matter in the air. This can be terrific news if you or someone in your family suffers from allergies or are sensitive to dust. A word of caution about high-efficiency filters, however. Before making the switch, contact your HVAC professional. A trained technician can help determine how disruptive the filter will be and perhaps even make adjustments to increase fan speed to make up for the reduced airflow. You’ll also want to make sure you stay on top of changing these more restrictive filters on schedule.

Keep in mind that a dirty HVAC air filter can cause more than just discomfort. They can lead to damage to the blower motor or heat exchanger. You can see the difference between a minimally restrictive fiberglass filter and a pleated filter in the below video.

If you have rooms that just don’t seem to get comfortable, check your air filters. If you are interested in switching to a higher MERV rated filter for cleaner indoor air, contact us at Althoff Industries, We’ll conduct an inexpensive clean and check and help determine the best HVAC air filter for your family. If adjustments need to be made, we can accomplish that on the same call.

Don’t settle for anything less than superior comfort when it comes to your indoor air. Contact Althoff Industries and get the indoor air quality you deserve.

3 Essential HVAC Tools that Provide Accurate Diagnostics

November 1st, 2017

At Althoff Industries, our priority is not only hiring and training talented technicians but equipping them with the highest quality tools to get the job done accurately. We ensure our technicians are not only well-trained and proficient in HVAC repair and installations but that they have the essential HVAC tools to assist them in the accurate diagnosis of your heating and air conditioning equipment.

While our trucks are filled with many parts, equipment, and tools, there are three HVAC technician tools that we use at every service call. They are the combustion analyzer, draft gauge, and manometer. These tools give us the ability to measure and analyze things happening with the system that cannot be seen by just visually looking at it. Our highly trained technicians understand that the proper diagnosis involves digging deeper to uncover hidden problems that impact safety, performance, and can cause breakdowns.

3 Essential HVAC Tools

1. Combustion Analyzer

A combustion analyzer is a handheld device that looks much like a multi-meter an electrician would use to check circuits. Like blood work being analyzed at the lab, the combustion analyzer gives our technicians all the components of the combustion process at once. The three main components checked are carbon monoxide levels, oxygen levels, and flue temperature. A trained technician knows that having just one of those numbers doesn’t tell you the whole story. It takes putting all the pieces together to accurately understand what’s happening. The purpose of the combustion analysis unit is to measure the percentages of oxygen and carbon dioxide along with the flue temperature. These measurements help our technicians determine whether or not the furnace is operating within the parameters that the manufacturer of the equipment has specified.

A combustion analyzer is important for three different reasons. It can help in determining and achieving optimum fuel efficiency, it is critical for the safe operation of your equipment, and it can ensure your HVAC system is operating within the guidelines of any warranty.

2. Draft Gauge

A draft gauge is a device that verifies that your chimney has proper draft pressure. Improper draft can be caused by lack of combustion air, too much combustion air, outside temperature and wind conditions, or a blocked chimney. A proper draft is critical to make sure the by products of combustion are safely disposed of outside the home. Most companies just assume this is happening correctly, at Althoff our technicians are trained to verify it. HVAC tools like a draft gauge help our technician determine if there are any problems creating these potential draft issues.

3. Manometer

The manometer is a device used to measure differences in pressure. We use this in a couple different ways. First, we use it to measure duct static pressure to make sure that you have proper air flow through the furnace and duct system. Another way is by measuring gas pressure to the equipment. Equipment is rated for certain gas pressures and those outside of those ranges can have very negative effects on performance, safety, longevity of the equipment

Other Trade Tools Used on Daily Basis

The three critical HVAC tools listed above are just part of what technicians need to perform their job on a daily basis. Other such tools may include:

A refrigerant recovery machine
Hand seamer
Swage tools
Leak detectors
Hand and power tools
Tin snips
Multimeter
Humidity and temperature gauges…and more!

Our technicians in the field often play the role of part technician, mechanic, sheet metal worker, detective, and chemist/scientist. It is why they are so extensively trained and outfitted with the latest equipment. It is not an inexpensive proposition but we take what we do very seriously here at Althoff Industries. After all, it is not just the efficient operation of your HVAC equipment that is at stake. It is also the safety of your family.

When you experience an issue with your furnace, trust the experts at Althoff Industries.
