A/C had been out for a couple days. Heat index 105° , 90 ° in house. I called 15 + HVAC companies and the earliest appointment time anybody could come was a week away. I called Barneys . He shot me straight and told me " I'll get you up and going today but it's going to be in the evening." He showed up about 7 pm which is perfectly fine as it was hot. He fixed the problem in 15 mins ( needed refrigerant ) He charged a very fair price. He stands by his word. LIFESAVER!! VERY COOL NOW!!!

HIGHLY RECOMMEND!!! My A/C went out late Friday night and not many companies were wanting to help and look at my unit until after the weekend and holiday was over, but Barney’s heating and air responded ASAP, and was here first thing in the morning on Saturday! The technician gave me an exact time and was here on time, other companies gave me a big time frame/window 8am-6pm and that just didn’t work for us. This company is affordable and willing to work with you. Definitely will call them again!! Thank you!

First time (in this house) getting our heat pump inspected. Technician was detailed in explaining what was both good & bad about our 12 year-old system. He explained that our system was still functional but also showed us a part that might fail in the future. He tested the part in our presence & gave us a fair price for replacement (which we did). We were comfortable enough with the service that we are likely to purchase a service/maintenance agreement this Fall.

I was impressed with the knowledge he had and how fair their pricing was.

Most Common Heat Pump Repair Questions

A malfunctioning heat pump can be a major source of stress, disrupting your home’s comfort and raising concerns about repair costs. Understanding some of the common problems and the repair process can help you feel more informed and confident when you need to call for service. Here are answers to some of the most frequent questions we hear from homeowners in Clarksville.

Seeing a thin layer of white frost on your outdoor unit on a cold, damp day is perfectly normal and is something the system is designed to handle. However, if the unit is encased in a thick layer of solid ice, it indicates a problem with the defrost cycle. The first thing you should do is switch your thermostat’s system mode to “Emergency Heat” or “Auxiliary Heat.” This will turn off the outdoor unit completely and activate your indoor electric heat strips to provide heat. This will keep your home warm and prevent any further damage to the heat pump’s compressor.

Do not try to chip or melt the ice off the unit with sharp objects or hot water. You can easily damage the delicate aluminum fins on the coil or other sensitive components. Once you have switched to emergency heat, the best course of action is to call a professional HVAC technician from Barney’s Heating and Air. A frozen outdoor unit is a clear sign that a component in the defrost system has failed. This could be a bad defrost control board, a faulty defrost sensor, or a problem with the reversing valve.

Our technician will need to diagnose which of these components is the root cause of the problem. They will safely thaw the unit and then run a series of tests to pinpoint the failure. For example, they can manually initiate a defrost cycle to see if the control board sends the signal and if the reversing valve actuates. Once the faulty part is identified, it can be replaced, restoring your system’s ability to keep itself ice free and operate efficiently throughout the winter.

When a heat pump stops working entirely, it is often due to an electrical issue. The first and simplest thing to check is your home’s main circuit breaker panel. Locate the breaker for the “Air Handler” or “Furnace” and the breaker for the “Heat Pump” or “Condenser.” If either of these breakers has tripped, you can try resetting it once. If it trips again immediately, do not reset it again. This indicates a serious electrical problem that requires professional diagnosis to prevent a fire hazard. There may be a short circuit in the system’s wiring or a failing motor.

If the breakers are fine, the problem could be a lack of power to the unit or a failed electrical component within the system. A common point of failure is the capacitor. A heat pump has several capacitors that provide the initial jolt of electricity needed to start the compressor and fan motors. These components can weaken and fail over time, and when they do, the motors will not start. A failed contactor, which is an electrical relay that sends power to the outdoor unit, can also cause the system to not turn on. Our technicians can quickly test and replace these common electrical parts.

Another potential cause is a safety switch that has been triggered. For example, many indoor air handlers have a condensate overflow safety switch. If the condensate drain line gets clogged and water backs up in the drain pan, this switch will shut down the entire system to prevent water damage. Similarly, a high pressure or low pressure safety switch on the compressor can shut the system down if it detects unsafe operating conditions. Our diagnostic process includes checking all these safety circuits to determine what caused the system to shut off.

Heat pumps make a variety of normal operating sounds, including the whoosh of the fan and the hum of the compressor. However, any new, loud, or unusual noise is a sign that something is wrong and needs to be inspected. A loud rattling or clanking noise can often be caused by something simple, like a loose panel door or debris like a twig or leaf that has gotten into the outdoor fan guard. It could also indicate a more serious issue, such as a motor bearing that is failing or a compressor that has come loose from its mountings.

A high pitched squealing or screeching sound is a serious warning sign that often points to a problem with a motor. Both the indoor blower motor and the outdoor fan motor can make this noise when their bearings are failing. If you hear this sound, you should turn the system off immediately to prevent the motor from seizing up completely. A squealing noise can also sometimes be caused by high pressure in the refrigerant system, which indicates a more serious problem with the compressor or a blockage in the system.

A loud buzzing or humming noise can indicate an electrical problem. This sound is often associated with a failing contactor or a capacitor that is trying to start a motor but cannot. The motor will hum as it tries to turn, which can lead to it overheating and burning out if not addressed. If you hear any of these abnormal sounds, it is best to call Barney’s Heating and Air for a professional diagnosis. Our technicians can interpret these sounds and quickly identify the source of the problem before it leads to a more catastrophic and expensive failure.

The “Emergency Heat” setting on your thermostat is a feature specific to homes with a heat pump system. This setting manually turns off your outdoor heat pump unit and relies exclusively on your secondary, or backup, heating source to warm your home. In most all electric heat pump systems in the Clarksville area, this backup source is a set of electric resistance heat strips located inside your indoor air handler. These strips work much like the glowing coils in a toaster, providing powerful but less energy efficient heat.

You should only use the Emergency Heat setting in two specific situations. The first is if your heat pump has a major malfunction, such as the outdoor unit being completely encased in ice or if it is making a loud, grinding noise. Switching to Emergency Heat allows you to keep your home warm while you wait for a repair technician, and it prevents further damage to the heat pump. The second situation is during extremely cold temperatures, typically below 20 degrees, if you feel the heat pump is struggling to keep up. However, your system should do this automatically.

It is important to understand that running your system on Emergency Heat will cause a significant increase in your electricity bill. Electric resistance heating is the least efficient way to heat your home, consuming three to four times more energy than your heat pump does under normal conditions. It is not intended for regular use. It is a backup system for true emergencies. If you find you have to use the Emergency Heat setting frequently, it is a clear sign that your heat pump is not functioning correctly and requires professional repair.

Whether a constantly running heat pump is normal depends on the outdoor weather conditions. During periods of very cold weather, close to or below freezing, it is actually normal for a heat pump to run for long, extended periods or even continuously. In these conditions, the system is working hard to extract enough heat from the cold outdoor air to maintain the temperature inside your home.

As long as it is producing warm air and maintaining your set temperature, this long run time is not necessarily a sign of a problem. It is just operating as designed to keep you warm.
However, if your heat pump is running constantly during milder weather, or if it is running all the time but failing to reach the temperature you have set on your thermostat, that indicates a problem. This could be a sign of low refrigerant due to a leak. An undercharged system has a reduced heating capacity, so it has to run continuously in an attempt to keep up with the heating demand. It could also be caused by a dirty air filter or dirty coils, which restrict airflow and heat transfer, forcing the system to run longer to do its job.

Another possibility is that your ductwork is leaking. If you have significant leaks in your duct system, a large portion of the warm air your heat pump is producing is being lost in your attic or crawlspace instead of being delivered to your living spaces. This forces the system to run nonstop to compensate for the lost heat. Our technicians can diagnose all of these potential issues to determine why your system is running excessively and restore its proper, efficient operation.

Yes, a refrigerant leak in a heat pump system can and absolutely should be repaired. In fact, it is illegal to knowingly top off a leaking system with new refrigerant without first making a repair. Refrigerant is a potent greenhouse gas, and releasing it into the atmosphere is harmful to the environment. A proper repair involves first finding the source of the leak, fixing it permanently, and only then recharging the system with the correct amount of refrigerant. At Barney’s Heating and Air, we follow strict EPA guidelines for all refrigerant handling and repairs.

Finding the source of a refrigerant leak can sometimes be a challenge, as they are often very small, pinhole sized leaks in the copper coils or at joint connections. Our technicians use several methods to pinpoint leaks. We often start with a visual inspection, looking for signs of oil residue, as the refrigerant often carries a small amount of oil with it that will stain the area around the leak. For more stubborn leaks, we use a highly sensitive electronic leak detector that can sniff out the chemical signature of the refrigerant in the air.

Once the leak is located, the repair method depends on its location. If the leak is in a straight section of copper tubing, we can often cut out the small damaged piece and braze in a new one. If the leak is in the indoor or outdoor coil, the repair can be more complex and may involve specialized sealing techniques. After the leak is repaired, we will pull a deep vacuum on the system to remove any air and moisture that may have entered. Finally, we will weigh in the precise factory specified charge of new refrigerant, ensuring your system is restored to its peak performance and efficiency.
