How Does A Gas Furnace Work?

These days it’s starting to get pretty cold and more and more of us are turning on our heaters. Here in Texas you probably have one of three types of heaters, a gas furnace, electric heat, or a heat pump. 

In this post I’m going to review the sequence of operations for a gas-fired furnace, and the types of components you’ll find to make it operate correctly. 

When you set your thermostat to “heat” and the temp in your home gets below the temperature you have set for your heater the thermostat sends a call for heat to your furnace. This kicks off the sequence of operations to start up your furnace and make sure that it burns safely and heats your home. 

Step 1:

The first thing that happens when your system gets a call for heat is that the inducer motor turns on. This is a small motor that creates a draft inside the heat exchanger so that all the products of combustion (once the gas lights on fire and starts to burn) get evacuated to the outdoors. 

Step 2:

Connected to the inducer motor is the pressure switch. This switch proves to the furnace control board that the inducer motor is operating correctly and removing the products of combustion.

Step 3:

Once the pressure switch proves the draft to the control board then we move on to step three, the hot surface ignitor turns on. This is a metal rod that gets hot and glows red to ignite the gas once it turns on. The hot surface ignitor turns on and glows red for 5-15 seconds to make sure it’s good and hot. 

Step 4:

Once the ignitor is hot the control board then turns on the gas. This is done via the gas valve. The gas valve takes the incoming gas from your home supply and reduces the pressure a bit so it burns as designed. It also regulates if the gas flows to the burners or not. Once the gas valve gets the signal it opens and flows gas through the burners. Once the gas hits the hot surface ignitor it lights and begins to burn. 

The Heat Exchanger

The heat exchanger is the device that holds the flames, gets hot, and that air blows across to heat up and then circulate through your home. The heat exchanger is essentially a collection of tubes. The fire burns into the tubes at one end, and at the other end the tubes connect to your furnace vent so the products of combustion exit the home. You don’t want these getting into your house. These tubes get hot from the fire burning inside them, then the blower pushes air across them which heats up the air before it circulates through your home.

Step 5:

Step 5 is the flame sensor. This sensor is another metal rod that sits right in the path of the flame and lets the control board know that a fire is burning. The purpose of the flame sensor is to tell the gas valve to turn off if no flame is detected. This way, if the ignitor is bad and the gas valve turns on but no flame lights, the furnace knows to turn off the gas rather than just keep it flowing. If the gas didn’t turn off you could have a really bad scenario with major life-safety implications. 

Step 6:

Once the flame sensor proves to the control board that a flame is present it starts a timer that counts down to turn on the blower motor and circulate air. Your furnace will wait until the heat exchanger gets hot before it turns on the blower, this is the purpose of the timer. This prevents the blower from circulating cold air through your home when the heater first comes on. By waiting, the heat exchanger gets hot, and when the blower motor comes on it circulates hot air from the start. 

Once the blower turns on your heater is operating as designed and will run until the temperature at your thermostat hits the set-point. But there are still two other safety’s in the furnace to protect you and your family in case of failure. 

Roll-out Sensor

The roll-out sensor sits inside the burner compartment and will shut off the furnace if the flames don’t stay directed into the heat exchanger channels. This can happen for a variety of reasons, like if your draft vent gets clogged and the products of combustion cannot exit the heat exchanger, or if the gas valve fails to regulate the pressure correctly, and on and on. The flame roll-out sensors shut down the gas valve so that the flames don’t lick out and start a fire in the furnace compartment. 

High-limit Switch

The high limit switch exists to shut down the gas valve if the temperature inside the heat exchanger gets too high. This can happen if step 6 fails, and the blower never turns on. Without air from the blower motor blowing across the heat exchanger it can overheat, melt, and start a fire. To prevent this the high-limit switch will shut the furnace off if the temperature gets too high. You can read more about high-limit switches here.

Diagnosing

This is a short summary of how your furnace works. 

When your furnace doesn’t operate correctly it could be any number of issues in the above sequence of operation. That’s why it is important to have your system cleaned and maintained twice a year, and if it does have an issue, to call a licensed professional to repair it.

How Does It Work Hiring Prestige Air?

We just updated the homepage of our website as well as the “Contact” page on our site to help everyone better understand how it works if you need our help getting your heater or air conditioner repaired.

In this post I want to explain the process a bit further.

Step 1: Give Us A Call

First, you have to give us a call. We don not offer online booking as of now, and this is because we want the opportunity to chat with you about the issue you’re having so we know what to expect when we show up. So for the time being, the first step to Prestige Air is to pick up the phone and give us a call.

When you give us a call we will get you on the schedule at a time that is convenient for you. More often than not we are able to get you on the schedule the same day. We do our absolute best to make sure this can happen because we no how miserable it can be to go without heat or AC for even a single night.

The initial appointment costs $39. This is our service call fee that helps cover the time and fuel needed to come to your house and diagnose the issue. But, this fee is waived if you hire us to make the repairs. If you choose not to hire us after the diagnoses, no worries, you pay the $39 service call fee and we will be on our way.

Step 2: Diagnose

Once we arrive at your home we will take a look at your system and do what we can to diagnose whatever is going on. Once we figure out why your heater or air conditioner isn’t functioning as designed we will come speak with you and give you a quote for the repairs.

At Prestige Air we use flat-rate pricing so you know exactly what you’re expected to pay for the quoted repairs. This way there are no surprises when we finish and request payment.

One thing to keep in mind about HVAC repairs is that sometimes we diagnose an issue, make the repair, and find another issue downstream from the one we just repaired. This is because there are times we cannot test the full system because of what has failed and it is not until we get the repair complete that we can then continue to test the rest of the system. We do our best to let you know when we think this might be the case, but sometimes it isn’t possible.

Either way, our commitment to you is that you know what you’re paying for before you approve the repair to your heating and cooling system.

Step 3: Repair

After you have approved the work we then move on to actually making the repair.

We made the decision to invest the money and purchase, and keep in stock, the most common parts that fail. This means we can usually make the repairs to your system on the same visit so that you have a working heater or air conditioner before we leave your home.

Sometimes the part that has failed is uncommon or proprietary to the manufacturer of that equipment. In that case we will have to go get the part, but can usually do this the same day, or within one business day. It is rare that we need to order a part that will take several days to arrive.

Step 4: Warranty

Finally, once the repairs are complete we get your signature that the work is done, and then we collect payment. Every repair, with few exceptions, comes with a minimum 1-year warranty on parts or labor. I wrote about the importance of warranties in a blog post here.

It is very important to us that you have peace-of-mind that your heating and cooling system will operate consistently if you hire us to make your repairs. So if anything goes wrong with the work we did we will come back and make it right.

We want to remove as much of your risk as possible when you hire us. In our mind it should be an easy and stress-free process to get your HVAC repaired.

*Warranty Exceptions

First, the condition of your system impacts our willingness to warranty the work. If your system is more than 10 years old, in bad shape, visibly not maintained, etc. we may not offer a warranty. This is because as systems age, get dirty, and aren’t maintained the possibility increases that the condition of the system is the cause of the failure. For example, dirt, dust, and organic growth can cause electrical shorts that burn out motors, control boards, or other electrical components. We can replace the parts, get the system up and running, but if those other issues still exist they may cause the part we installed to fail once again, at no fault of our own.

Second, if the system is not set up as designed by the manufacturer we may opt out of offering you a warranty. What I mean by this is, if a tech from another company came out previously (whether it was last week, or 3 years ago), and made some change to the system in the course of his work, and it no longer conforms to the manufacturer’s design, like if an electrical component fails and rather than put the correct component in the system he wires the system differently and adds a completely different component so he doesn’t have to leave and get the correct part, we most likely will not warranty our repairs. At least not until the system is restored to the manufacturer’s specifications.

Another example of this type of issue is when AC technicians bypass safety switches because they can’t figure out why the safety keeps cutting the system off. Switches like high and low pressure sensors, high temperature cut-off switches, etc.

All of these substandard repairs not only put the system at risk for continued failure, they also put you, your family, and your home at risk for catastrophic failure.

Rest assured, if we find these conditions we will let you know, but as I said, until this is resolved we will not warranty our work. The potential that this previous substandard work can cause our repairs to fail is too high and we are not willing to take on that risk.

You should also know, these examples are very rare, but I wanted to be up-front about how our warranty works. Our goal is that you feel comfortable hiring us and knowing that you will get top quality repairs and that if anything goes wrong we will stand behind our work.

As Simple As 1+1

Hiring Prestige Air should be incredibly simple, as simple as 1+1. Your system fails + you call Prestige Air, then everything goes back to normal so you can live your life in comfort.

  • You speak with a real person to schedule your call
  • We can usually come out the same day
  • You know the cost of the repair before you approve it
  • We can usually make the repair on the same visit
  • You get a minimum 1-year warranty on the parts and labor

That’s about as simple as it can get.

Does My Air Filter Improve My Indoor Air Quality?

Dirty heater and air conditioner air filter

The short answer is no, but let me explain. 

The air filter in your heater and air conditioner is one of the most vital components of the system. Dirty or missing filters are, without a doubt, the number one cause of heating and air conditioning breakdowns and failures. 

What is The Purpose of the Air Filter?

A very common misconception is that the your filter is intended to clean the air in your home. The truth is, the filter exists to protect the heater and air conditioner alone. As the air from your home is pulled in to your heater and air conditioner it is vital that dust, dirt, pet hair, etc. is contained before it enters the system. If this foreign debris gets into the heater or air conditioner it will clog the evaporator coil or get hung up on the heat exchanger. If this happens the airflow is restricted which causes a host of other problems, things like freezing coils, increased pressures, burned out compressors, increased furnace temperature, etc. All of which can be incredibly damaging to either the heater or the air conditioner. 

Does the Air Filter Clean the Air?

As I said a moment ago the filter pulls large contaminants from the air, things like dust, pollen, pet hair, dirt, etc. But this doesn’t mean your air is clean. The real dangers in the air you breathe are things like virus’, bacteria, mold spores, chemicals, and VOC’s (volatile organic compounds). 

For example, most people don’t realize that the cushions in their couch are hydrocarbon based foam. They are essentially gasoline that has had a chemical added to it that made it turn to foam. Over time this foam begins to breakdown and off-gas, putting off hydrocarbon chemicals into the air in your home. This is an example of what needs to be removed. 

What Will Clean My Air?

Have you ever noticed how the air outside (unless you live in a dense, traffic-ridden city) is so much nicer than the air in your home? This is because nature has processes built into it to clean the air. The UV rays from the Sun kill germs, the wind blowing through fields of grass and through leaves (which filters it), the rain falling, etc. all clean the air. 

To clean the air in our homes we try to imitate nature. Proven indoor air quality devices us UV bulbs, ionization, and produce hydrogen peroxide or ozone to sanitize, clean, and purify the air we breathe. 

If your goal is to clean the air you breathe, and remove the toxins from your home, your heating and air conditioning filter won’t do the trick. You need a whole home indoor air quality (IAQ) device. We prefer the REME Halo. If you’d like more information on what type of IAQ device would meet your needs give us a call. We are experts with indoor air quality.

3 Questions to Ask Before Hiring an HVAC Company

3 Questions to Ask Before Hiring an HVAC Company

You are well aware that there is no shortage of HVAC contractors in the marketplace. And when you have a large number of companies servicing heating and air conditioning you are bound to have a wide spectrum of quality in the mix. Some contractors may offer exceptional quality, while others are just looking to make a buck. With that in mind, I have compiled a list of the three of the more important questions to ask when hiring an HVAC contractor to help make sure you get the quality work you expect. 

Read below to learn about these questions and also a short explanation as to why they matter.

First, Is the Company Licensed and Insured for Heating and Air Conditioning Repair?

A lot of people overlook the need for a license in the trades. “My brother-in-law used to do HVAC, he can help me”, or “My neighbor says he did his own last year and he can help me out”, are phrases we here all the time. So why is a license important?

Licensing ensures that the contractor has met certain basic requirements to operate in your state. A license ensures that the contractor has a specific amount of experience, and has shown a thorough knowledge of local codes and requirements to make sure that they are knowledgeable in the work they do and that this work will be safe for you and your home. The license also requires that they have the necessary insurance to protect if things go wrong.

I was a firefighter for 10 years before I got into the trades, and what a lot of people do not know about local code requirements is that they stem from three major fires. The London fire, the Chicago fire, and the San Francisco fire, all started as a single small fire that then went on to destroy an entire city. Why? Because everyone built their homes and businesses as they saw fit, with no oversight as too what was safe or not. 

These catastrophes compelled governments to develop codes for how to build and repair homes and businesses, for the safety of everyone involved, and to date, we haven’t had anymore small fires destroy large cities. 

I’ll admit some code requirements are hard to understand and can be pretty weird and petty, but in general they exist to keep you, your home, your neighborhood, and your city safe. You need to make sure you hire a contractor who is licensed and has shown that he knows these codes and knows how to keep you safe with the work he performs. Next you should ask…

Do They Have Good References?

It’s very easy for someone to get business cards, build a website, and put a sign on a van to give the appearance of being professional. It’s much harder to do good, quality work that more than satisfies your customers and to build a good reputation in the process. 

The easiest way to separate the legitimately professional contractor from the phony is to ask for references. That said, some heating and air conditioning contractors don’t want tire-kickers bombarding their existing customers with questions, which is reasonable. So a second way you can check references is to read Google reviews. Google is very strict on their review policy and the contractor has no say over what gets written. The contractor can’t edit them, or remove them. So you can rest assured that you are getting an accurate picture if you read Google reviews. 

But don’t just read the good ones. Read the bad ones as well. When the contractor makes a mistake, which we all do, how did they handle it? How did they handle a dissatisfied customer? All of this is good information to have before you choose a contractor. And finally you should ask…

Do They Warranty Their Work?

To be very blunt, an HVAC contractor who does not warranty his work has no faith in his own ability (or his employees’) to repair your heating and cooling system. It really is that simple. A qualified and well-trained contractor knows how to repair your HVAC system and will offer a warranty to back it up. So before you hire an HVAC contractor ask about their warranty. But also be aware that some warranties have stipulations, things like regular maintenance, the age of the system, etc. These are all factors that have nothing to do with the contractor’s repair but can cause failure, so don’t let stipulations to the warranty turn you off automatically, listen to what they are, and then decide for yourself if you think it makes sense or not. 

In the end, if you ask these three questions, and do your homework in the process, you are much less likely to get scammed by an unsavory HVAC contractor and much more likely to get quality heating and air conditioning repairs.

What Is A “Manual J” Calculation and Why Do I Need One?

What is an ACCA Manual J load calculation?

Manual J is the book created by the Air Conditioning Contractors Association that holds all the tables, charts, measurements, and definitions for determining the heat load in a living space. A Manual J calculation is simply running a heat load for your home. 

What Is A Heat Load?

A heat load is a measurement of how many BTU’s (British Thermal Units) of heat need to be added or removed from a structure to maintain a specific design condition. Put more simply, it is how much heating or cooling we need to provide your home to keep you comfortable. 

Different Variables We Must Consider

Every dwelling leaks air to some degree or another, which means that heat gets in during the warmer seasons and cold air gets in during the colder seasons. The question is, how much?

Things like the type of windows, how many panes of glass, what the frame is made of, how old they are, the type and size of doors, how much insulation, do you have a fireplace, etc. are all factors. 

According to Manual J a single fireplace leaks 20 cubic feet a minute of air into and out of the home. That’s 600 cubic feet of air an hour. This absolutely affects the ability of your heating and cooling system’s ability to keep you comfortable. 

When trying to determine the correct size of the system for your home we need to take all of this into account. 

We also have to account for anything that adds heat within the home as well, such as appliances. Do you have a large kitchen with a double oven that is used frequently? 6 burner stove top instead of 4? Do you have any terrarium with heat lamps for any pets? All of these add extra heat that needs to be factored in. 

Not to mention other factors like ceiling height, attic insulation, is your floor a cement slab on the ground or is it pier and beam that is raised off the ground?

All of these play into the final calculation to help us determine how much heating and cooling to add to your home.

Hasn’t This Already Been Done for My Home?

We get asked all the time why we need to do this again when the home already has an HVAC system installed and since the builder did this when they constructed the home. 

This is a great question. Many companies look at your existing system, find that it is a 4 ton, and just replace it with a 4 ton. We don’t.

The reason we run a heat load calculation every time we change out a system is because homes deteriorate and conditions change. You may have changed the windows, remodeled, changed the floor plan, etc. When we change out your system we warranty our work, which means we are warrantying your comfort. This means we do not want to assume the builder, or last HVAC company, or previous homeowner, did it correctly. We want to do it ourselves. This way we can have confidence that the correct system was installed and that you will always be comfortable. 

If you have any concerns about the proper sizing for your home’s heating and cooling system give us a call, 817-200-7215.

The Importance of a Heater’s High Limit Switch

High Limit Switch Installed in a Furnace

How Your Heater Works

Every heater, whether it is a gas furnace or electric heater (that uses electrified heat strips) operates in a similar fashion: heat builds up in a box and the blower motor then blows air through the box to force the heat into the living space. 

If you have a gas furnace the heat is generated in the box by a gas fire that is burned inside a heat exchanger. If you have an electric heater then heat is generated in the box by heat strips that are energized with 220-240v of electricity (much like an electric stove top). 

The blower motor, which blows air from your home through this heated box, distributing the warmer air throughout your home, keeps the box from over-heating.

Purpose of the High Limit Switch

Can you imagine what would happen if the blower stopped moving air through your heater? The box where the heat is generated would just continue to get hotter and hotter, ultimately causing a catastrophic failure in your system, which oftentimes leads to a fire in your home. 

The circulation of air through your heater is what keeps the heat from building up to a dangerous level, so if this stops, the heat can easily become dangerous. 

This is where the “high limit switch” comes into play. This tiny little switch is the safety to keep your gas furnace or electric heater from damaging itself and your home. The high limit switch has a sensor that when the heat in the box gets too high (as would be the case if the blower failed), cuts power to the heating portion of the system.  

Cutaway of a High Limit Switch

Maintenance is Key

There are many different components needed to run your blower motor and circulate the air through your heater, components like control boards, fan relays, sequencers, and the like. If any one of these many components fails, your blower will stop working and stop circulating air through your heater. The high limit switch will then turn off the heating capability, protecting the system and your home. 

This is one of the many reasons to have your system maintained twice a year. Your system may run fine and you won’t know you have a faulty high limit switch until your blower fails and nothing exists to cut off the heating capability of your system, ending in catastrophic failure. 

Testing a high limit switch is an easy process for a trained technician, and one that goes a long way to preserving your system and your home. This very small component serves a very big purpose.

Should I Repair or Replace My Existing HVAC Unit?

Old furnace vs New furnace

Unfortunately, heating and air conditioning system breakdowns are a fact of life. It’s the second law of thermodynamics…that everything tends towards breaking down and disorder. 

This then inevitably brings up the question, should I pay to repair my heater or air conditioner, or should I just replace it?

There are a few factors required to answer this question. Things like the age of your system, your average annual repair costs for the system, etc. On one side, it’s just a simple math problem, one I will walk you through in a moment. On the other side it’s about your comfort and peace-of-mind, something that isn’t quite quantifiable. 

Doing the Math

There are three numbers we need to figure out to determine if you should repair or replace your system. 

  1. Energy costs
  2. Repair costs
  3. Replacement cost

Energy Bills

First, how much could you save on energy if you updated your system? We start with how much you spend on heating and cooling costs monthly. According to the national energy department Texan’s heating and cooling costs are about 65% of their energy bill (this varies based on whether you have a gas furnace, heat pump, or electric heater). So take your average monthly energy bill and multiply it by .65

For example, a $300/mo. energy bill would mean you spend $195/mo. for your heating and cooling. 

Next, we need to determine what you would save on your energy costs with a new system. You can find several calculators online that will let you know what your annual savings will be, but for the purposes of this post we will use the example of upgrading from a 10 SEER HVAC to a 14 SEER HVAC. The energy savings annually for this upgrade are 30% (of just your HVAC utility costs) 

That looks like this: $195 x .3 = $58.50

This means that upgrading your system to a newer 14 SEER HVAC system would save you $58.50/mo. on your energy bills. 

Repair Costs

Next, we need to figure out what you can expect to spend on repairs for your system over the next 5 years. To do this we ask you what you spent to repair it last year and the year prior. From there we project out the next five years with a 10% increase each year. We do this because as systems get older they require more frequent, and more costly, repairs. 

If your average annual repairs over the last 2-3 years were about $400 the numbers would look like this:

Annual Estimated Repairs: $400

Year 1 + 10%: $440
Year 2 + 10%: $484
Year 3 + 10%: $532.40
Year 4 + 10%: $585.64
Year 5 + 10%: $644.20

Total Repairs Over Next 5 Years: 2686.24

Then we divide by 60 to get your average monthly repair costs for the next 5 years. 

Divided by 60= (Monthly Repair Costs): $44.75

Adding It Up

Now we add your energy savings to your repairs costs and we can determine what you are paying every month to keep your existing heating and air conditioning system. 

Repairs + Utility Savings: $103.25

This means it is costing you $103.25/mo. to keep your existing system. 

What Would A New System Cost?

Next we determine the cost of a new system. For example, if you wanted to replace your existing HVAC system with a new 14 SEEr system and it costs $7,500. You finance it for 72 months (6 years) at 9.99%, then your monthly payment would be: $131.25

Compare this to the cost of keeping your existing system and we get this:

Cost to keep existing system: $103.25 (energy and repairs)

Cost to upgrade: $131.25 (monthly finance payment)

Monthly Net: -$28

In this example it would cost you an extra $28/mo. to replace your system. Sometimes, depending on energy costs and repair costs, you actually save money by upgrading, but in this example you don’t. 

This doesn’t necessarily mean you should just opt for the repairs though. Now we turn to the unquantifiable factors like comfort, and peace-of-mind.

Comfort

How is your existing system doing when it comes to keeping you comfortable? How well does it run? What are your existing heating and cooling needs? Do you have rooms that won’t heat or cool well? Are you concerned about indoor air quality? 

All of these questions, and more, can point us to issues that may be resolved with an upgrade. Upgrading your system provides an opportunity to resolve many issues that may have slowly crept in with your existing system, Issues you may think are well worth the extra $28/mo. to solve. 

Peace-Of-Mind

Does your system consistently breakdown in the peak of each season, when it’s hottest outside, or coldest outside? Have you come to expect these breakdowns? Are you constantly worried about the next breakdown? Do you have very young children, or elderly parents or grandparents living with you, who are adversely affected when your system breaks down?

Any new system we install comes with a 10-year manufacturers warranty on parts and a 1-year warranty on labor. A new system not only provides an opportunity to fix any issues to your comfort, but can also offer peace-of-mind, knowing that breakdowns are a thing of the past, and that warranties have you covered. 

Putting It All Together

After doing the math regarding your current heating and cooling system, and a potential upgrade, along with asking yourself the questions about comfort and peace-of-mind, you can then decide if it is worth it to upgrade, or just repair your existing HVAC unit. 

If you’d like help with this process, or just have more questions give us a call and we would be happy to serve.

Why We Use Flat-rate Pricing

Two Types of Pricing

In the HVAC industry there are two main ways to set prices for the services we offer. 

  1. Time and materials 
  2. Flat-rate pricing 

Time and materials is where we charge based on a slightly marked up price for the materials needed for the job, along with an hourly rate for the time it takes to do the work on your heater or air conditioner. 

Flat-rate pricing is where we charge a flat rate for each service, predetermined before we ever show up at your home, based on all the costs associated with running an HVAC business, which includes the materials needed for the job along with the time needed to make the HVAC repairs.

Pros and Cons of Each

Time and materials has a few cons associated with it. First, you as the customer do not know what the cost of the repair will be until it is completed. This is because we don’t know how long it will take to do the repair. What if we run into unknown snags with your air conditioner? What if your furnace is particularly difficult to work inside? There is no way to know how long the repair will take. It also means that if you get a newer, less efficient tech that you pay more, since he isn’t as proficient as a more seasoned tech and has to analyze more and inevitably takes longer. You might have the same repair as your neighbor and you both pay different amounts because you had different technicians doing the work, one faster than the other. 

With time and materials you, the homeowner, take all the risk. 

With the flat-rate pricing model we take all the risk. Since we have predetermined the price of your HVAC repair before we ever showed up at your home we can give you the repair quote before we start servicing your heater or air conditioner. Regardless of how long it takes you know that you and your neighbor now both paid the same price for the same repair. You don’t have to wonder about how much it will cost or how long it will take. You can make an informed decision before you sign-off on the repairs. 

If the air conditioner or heater repair takes too long we absorb the extra cost, so the efficiency of the technician is no longer your concern. Just to be clear, all of our techs are trained and certified and do great work, but it is a fact that the longer you do something the faster you get at it. Time on the job is what I mean when I say efficiency, not the quality of the repair. We warranty all repairs because we believe in our techs and the level of their training. You never need to worry about this. 

In Summary

With time and materials…

  • You don’t know the cost of your heater or air conditioner repair until it is completed
  • You pay more if you get a less efficient technician
  • You and your neighbor may pay different amounts for the same heater or air conditioner repair
  • You take all the risk

With flat-rate pricing…

  • You know the cost before you sign-off
  • You pay the same price regardless of how long it takes 
  • You and your neighbor pay the same price for the same heater or air conditioner repair
  • We take all the risk

For these reasons, to keep your best interest at heart, and to maintain total clarity on the cost of our HVAC repair services, we have chosen to use flat-rate pricing for our heater and air conditioner repairs.

What is AUX Heat on my Heat Pump?

How Your Heat Pump Works

Heat pumps are incredible feats of engineering, but like most appliances have their limits. Heat pumps provide very energy efficient heating when compared to traditional electric central heating air handlers, but due to the science behind their design can only go so far.

We spoke in detail about how your heat pump works on an earlier blog, which you can read here. But I will go ahead and give you a quick summary.

In cooling mode your HVAC system uses the evaporator coil inside your home to absorb the heat in the air (into the refrigerant) and then sends the heat to the condenser/outdoor unit and rejects the heat (from the refrigerant) and then starts the process back over. Pretty simple.

With a heat pump, when you switch to heat mode your HVAC system reverses the flow of refrigerant. Now your condenser/outdoor unit is absorbing heat from outside (into the refrigerant) and sends the heat indoors to the evaporator coil and rejects the heat (from the refrigerant) into your home.

Heat Pump Limitations

The limitation of the heat pump is based on the science of refrigerant. The temperature of the refrigerant in your condenser, when in heat mode, is between 35-42 degrees. Heat transfers from the warmer object to the colder one, which means that if it is below that 35-42 degree temperature your condenser is giving off heat, not absorbing it. When this happens there is no heat in the refrigerant to reject inside your home and your heat pump blows cold air.

The Purpose of AUX Heat

This is where AUX heat, or EM heat (emergency heat) comes into play. Inside the air handler (indoor unit) of every heat pump are electric heat strips. These work just like an electric stove. When energized the resistance of the heat strips causes the strip to get hot and glow bright red. As your blower motor moves air across these strips the air gets warm and circulates through your home.

The purpose of AUX heat/ EM heat is to supplement your heat pump on days when the temperature gets below 35-42 degrees. Some thermostats can be programmed to make the switch automatically based on an outdoor ambient heat sensor, others need to be switched over manually. If you notice that your heat pump is blowing cold air from the vents when in heat mode, check the outdoor temperature. If it is below the 35-42 degree window switch your thermostat over to AUX heat or EM heat.

AUX Heat As A Backup

AUX heat or EM heat also operates as a back up in case anything goes wrong with your heat pump. If the refrigerant leaks out, or the condenser has a failure you can simply switch to AUX heat and remain warm until repairs can take place.

If you have any questions or concerns regarding your heat pump or HVAC system in general and live in the Fort Worth area give us a call, we’d love the opportunity to serve.
