My AC hadn’t been working for the past few days. We quoted 2 different companies and they were unreasonably priced. Finally when I contacted Affordable they were able to come out that same day. They were so nice and understanding of mine and my husband’s financial situation and were able to replace our unit the following day for a reasonable price. 10/10 would recommend!

This company is truly affordable and awesome! When we are ready for a new unit we will be using them. Our a/c went out right before the extreme heat wave. We are new to the area, saw this company online, called and Bobby came out the next morning. He found the issues, fixed them, set us up for service schedule, but most importantly-did not price gouge us nor try the whole "You need a new unit now" salesman stuff as it was not needed at this time. He was extremely informative-told us what to do going forward. Bobby-you saved us big time! THANKS!!!

Heat Pump Repair Service in Ten Mile, TN

A malfunctioning heat pump can disrupt your home’s comfort at any time of year. Since it is responsible for both heating and cooling, a breakdown can leave you sweating in the summer or shivering in the winter. At Affordable AC & Service, our heat pump repair service is designed to be responsive, efficient, and thorough. Our technicians are equipped with advanced diagnostic tools to quickly get to the bottom of the problem. We focus on identifying the root cause of the failure to provide a durable repair, not just a temporary fix, ensuring your system is reliable again.

Our team of skilled technicians is proficient in handling the full range of heat pump problems. One of the most common issues we see is a heat pump that is blowing cool air when it should be heating, or vice versa. This often points to a problem with the reversing valve, the component that switches the flow of refrigerant between heating and cooling modes. We can also resolve issues like a unit that is frozen over in the winter, a system that is making loud or unusual noises, or a heat pump that simply will not turn on. No matter the issue, we have the expertise to solve it.

The repair process always begins with a detailed diagnostic inspection of your entire system. Our technician will check both the indoor air handler and the outdoor unit. They will test electrical components like capacitors and contactors, inspect the refrigerant levels and pressures, and check the operation of the fans and motors. This comprehensive assessment allows us to give you a precise diagnosis. We will then clearly explain the problem and provide you with a firm, upfront price for the repair. You will approve the cost before any work is done, ensuring full transparency.

Once you authorize the repair, our technician will get to work. We use only high-quality, OEM or equivalent replacement parts to ensure the longevity and performance of our repairs. Our technicians work with precision and a commitment to quality craftsmanship. They will handle your property with respect, keeping the work area clean and tidy. Safety is paramount in all our work, especially when dealing with high-voltage electrical components and pressurized refrigerant. Every repair is performed according to the highest industry safety standards.

A frequent issue with heat pumps in the winter is a failure in the defrost cycle. If your outdoor unit is encased in a block of ice, it cannot heat your home. This can be caused by a faulty defrost control board, a bad sensor, or a problem with the reversing valve. Our technicians are experts at troubleshooting the defrost system to identify the failed component. We can quickly replace the faulty part and restore your heat pump’s ability to operate effectively even on cold, damp winter days.

Electrical failures are another common culprit in heat pump breakdowns. The constant year-round operation can put stress on electrical parts. A failed capacitor can prevent the compressor or fan motor from starting. A burnt-out contactor can stop the outdoor unit from running at all. A problem with the control board, the brain of the system, can cause all sorts of erratic behavior. Our technicians can safely diagnose these electrical issues and replace the necessary components to get your system back online.

We are so confident in the quality of our work that we back every heat pump repair with our industry-leading 5-year labor warranty. This is our promise to you that we provide lasting solutions. As a veteran-owned business that has been a trusted part of the Ten Mile community for over three decades, our reputation is built on reliability and customer satisfaction. When your all-in-one comfort system lets you down, call the team that stands behind their work: Affordable AC & Service.

Common Heat Pump Repair Questions

When your year-round comfort system stops working, it can be confusing. To help our customers in Ten Mile understand potential issues, we have answered some of the most common questions about heat pump repair. This knowledge can help you know when to call for professional help.

A heat pump blowing cold air when it is set to “heat” is one of the most common complaints we receive, and there are several potential causes. One of the most frequent issues is a problem with the outdoor unit’s defrost cycle. If the outdoor coil is covered in ice, it cannot absorb heat from the air, so the air circulating inside will be cold. Your system might be entering its defrost cycle to melt this ice, and during this brief period, the backup heat should engage to temper the air. If the backup heat is not working, you will feel cold air.

Another very common reason is low refrigerant charge due to a leak. Refrigerant is the lifeblood of your heat pump, and if the level is low, the system lacks the capacity to generate enough heat, resulting in cool air coming from your vents. This is a problem that requires a professional to find and repair the leak before recharging the system. Simply adding more refrigerant without fixing the leak is not a proper or lasting solution.

The problem could also be more mechanical. The reversing valve, which is the component responsible for switching the system between heating and cooling, could be stuck in the cooling position. If this valve fails, the heat pump cannot be switched into heating mode. This is a repair that requires a skilled technician to diagnose and replace the valve. Because there are numerous potential causes, it is essential to have a qualified professional from Affordable AC & Service diagnose the specific reason your heat pump is not heating correctly.

It can be normal for a thin layer of white frost to form on the outdoor heat pump coil during winter operation, especially when it is cold and humid. Your heat pump is designed to handle this by periodically running a defrost cycle to melt it away. However, if the outdoor unit is covered in a thick layer of ice or becomes completely encased in a block of ice, it is a clear sign that something is wrong. A heavily iced-over unit cannot function properly and requires immediate professional attention.

This excessive ice buildup typically indicates a problem with the defrost cycle. The defrost control board may have failed, or the temperature sensors that tell the board when to start the defrost cycle may be faulty. The problem could also be related to the reversing valve not shifting properly to allow hot gas to melt the ice. If the defrost cycle is not working, the ice will continue to accumulate until the unit can no longer transfer heat, at which point it will stop heating your home effectively.

Other issues can also lead to excessive icing. Restricted airflow caused by a dirty air filter or a blocked outdoor coil can contribute to the problem. An incorrect refrigerant charge can also cause the coils to operate at the wrong temperature, promoting ice formation. You should never try to chip or melt the ice off the unit with sharp objects or hot water, as you can easily damage the delicate coil fins or other components. The best course of action is to turn the system off and call for a professional repair.

The decision to repair or replace an old heat pump depends on a few key factors: the system’s age, the cost of the repair, and its recent repair history. Heat pumps typically have a service life of about 10 to 15 years. Because they run year-round, they can wear out faster than a separate furnace and AC. If your heat pump is over 10 years old and is facing a major repair, replacement is often the more financially sound option in the long run. A new system will be more efficient, more reliable, and will come with a full warranty.

You should apply the “50% rule” to the decision. If the estimated cost of the repair is 50% or more of the cost of a new heat pump installation, replacement is generally recommended. Investing a large amount of money into an old, inefficient system that is likely to have more problems in the near future is not a good use of your resources. It is also important to consider the frequency of repairs. If you have had to call for service multiple times in the last couple of years, your system is telling you it is nearing the end of its life.

Energy efficiency is another critical consideration. Heat pump technology has advanced significantly. A new, high-efficiency heat pump can have SEER2 and HSPF2 ratings that are much higher than your old unit, leading to substantial savings on your monthly energy bills. The money you save on electricity can help offset the cost of the new system over time. Our technicians will provide a clear, side-by-side comparison of the repair and replacement options, helping you make the best choice for your home and budget.

If your heat pump will not switch from heating to cooling, or vice versa, the problem is almost always related to the reversing valve. The reversing valve is an electrically controlled, four-way valve that directs the flow of refrigerant through the system. In one position, it directs the refrigerant to flow for cooling, and in the other position, it directs it to flow for heating. If this valve gets stuck or the solenoid that controls it fails, your heat pump will be locked in one mode of operation.

The most common cause of this issue is a failure of the reversing valve solenoid. The solenoid is a small electromagnet that receives a signal from your thermostat and physically moves a slide inside the valve to redirect the refrigerant. If the solenoid coil burns out, it will no longer be able to move the slide, and the valve will remain stuck in its last position. A technician can test the solenoid and, if it is faulty, it can often be replaced without replacing the entire valve assembly.

In other cases, the valve itself may be mechanically stuck or damaged internally. This is a more significant repair that requires a technician to recover the refrigerant from the system, cut out the old valve, braze a new one in its place, and then recharge the system with refrigerant. It is a complex job that should only be performed by a certified professional. If your system is stuck in one mode, it is a clear sign you need to call Affordable AC & Service for a diagnosis.

Loud humming or buzzing noises from your heat pump usually indicate an electrical problem that requires professional attention. One of the most common sources of a loud hum is the contactor. The contactor is an electrical relay that sends power to the compressor and outdoor fan motor. When it begins to fail, it can vibrate loudly or “chatter.” A failing contactor should be replaced before it fails completely or causes damage to more expensive components like the compressor.

Another frequent cause of a buzzing or humming noise is a failing capacitor. Heat pumps have capacitors that help the compressor and fan motors start and run. When a capacitor is failing, the motor it is connected to may struggle to start, drawing a lot of power and creating a loud hum. If the motor cannot start, it can quickly overheat and burn out. Replacing a capacitor is a relatively inexpensive repair, but failing to do so can lead to a very expensive motor replacement.

In a more serious scenario, the humming noise could be coming from the compressor itself. This can happen if the compressor is struggling to start due to an internal mechanical issue or an electrical problem. A compressor that is humming but not starting is in danger of burning out. Because these noises are almost always tied to the electrical system, it is important to not ignore them. It is best to turn the system off and call a professional to diagnose the issue safely.

The cost of a heat pump repair can vary widely depending on what is wrong with the unit. Minor repairs are the most affordable and can include things like replacing a faulty capacitor, a contactor, or a thermostat. These repairs involve relatively inexpensive parts and can usually be completed fairly quickly by a skilled technician. Cleaning a dirty coil or clearing a clogged condensate drain also fall into this lower-cost category. We always provide free estimates and upfront pricing for any repair, no matter how small.

Mid-range repairs involve more expensive parts or more intensive labor. For example, replacing the outdoor fan motor or the indoor blower motor is a more significant job. Repairing a refrigerant leak can also fall into this category; the cost will depend on the location of the leak and how much refrigerant needs to be added after the repair is complete. Replacing a defrost control board is another common mid-range repair. Our technicians will always explain the need for these repairs and provide a clear quote before beginning work.

The most expensive heat pump repairs involve the system’s core components. Replacing the compressor, which is the heart of the system, is a major and costly repair. Replacing the reversing valve is also a complex and labor-intensive job. In these situations, especially if the heat pump is older, we will provide you with a detailed cost-benefit analysis, comparing the high cost of the repair to the cost of installing a new, more efficient system that comes with a full warranty, including our 15-year labor warranty.

A heat pump that turns on and off in short, frequent bursts is a condition known as “short cycling.” This is a serious problem that is very inefficient and puts a great deal of stress on the system’s compressor, which can lead to its premature failure. One of the most common causes of short cycling is a severely clogged air filter. If the filter is dirty, it restricts airflow across the indoor coil. This can cause the system to quickly overheat in heating mode or freeze up in cooling mode, triggering a safety switch to shut the unit off. It will then restart a short time later, repeating the cycle.

Another very common cause of short cycling is an oversized heat pump. If the unit installed in your home is too large for the space it needs to condition, it will reach the thermostat’s set temperature very quickly and shut off. Because it did not run long enough to properly dehumidify the air or circulate it evenly, the temperature will feel uncomfortable again quickly, causing it to turn back on. This is a sign of an improper installation, and unfortunately, the only true solution is to replace the unit with a correctly sized one.

Other potential causes for short cycling include a low refrigerant charge, which can also cause the system to trip its safety sensors. A faulty thermostat that is not reading the room temperature correctly can also be the culprit. A technician from Affordable AC & Service can properly diagnose the reason for the short cycling. It is an issue that should be addressed immediately to prevent damage to your compressor, which is the most expensive component in your heat pump.
