Heat pump repair professionals report that one of the reasons why people prefer heat pumps to other HVAC systems is because they distribute air much better than the standard HVAC units. The units also tend to be more energy efficient. Unfortunately, just like the other heating systems, they tend to develop a wide range of problems that you should be aware of. Some of these problems include:
Failure of the heat pump to function
You will switch on the heat pump but it won’t give you the warm air that you are looking for. When you are having this issue, there are plenty of things you can do to troubleshoot the problem.
The first thing you should do is to check the circuit of the electrical panel and confirm whether it’s on or off. If the circuits aren’t the issue, try flushing the drain line. The cool thing is that it’s easy to do it and you can do it by yourself without any problems.
If everything is working properly but still the unit won’t turn on, you might be having another more complicated issue that you can’t fix by yourself. In such a case, you should hire a professional to help you with inspecting and fixing the problem.
Failure of the heat pump to heat the house
Sometimes the heat pump will be on but it won’t heat the house as you would want it to. If this is the case with your unit, you should check the thermostat and confirm that it isn’t turned off or adjusted inappropriately.
Sometimes the issue is due to dirty coils in the outside condensing unit. For you to fix the problem you only need to gently brush the coils with a nylon or natural bristle brush. Also, remember to hose off the debris that might be present.
You might find yourself in a scenario where the thermostat is properly set and the coils are clean but still, the unit won’t heat up the house as effectively as it’s supposed to. If this is the case with your unit, you should hire an HVAC professional to inspect the unit and find the source of the problem.
The heat pump should be making some low sounds but when the sounds are out of the ordinary, you have a reason to worry. Many people ignore the sounds as they often don’t lead to the failure of the heating units, but you shouldn’t be one of the people that ignore them.
You should note that sounds mean that there is something very wrong with your heating system and you need to address the problems as fast as you can. Different sounds mean different things; therefore, you should be aware of them. The most common sounds include:
Humming noises: These come about due to improperly working fan motors. If you are having a vibration hum, you might be having loose items in the condensing unit.
For you to fix the issue you need to tighten the loose parts. You also should consider placing foam rubber between the rubbing parts to stop the noise.
Sharp buzzing noise: This often indicates a bad start relay or capacitor
Whistling: In most cases, whistling noises are due to debris clogging the thermostatic expansion valve (TXV).
Rattling: Rattling noises signify a hard-starting issue. The compressor might also be starting to fail.
Regardless of how minor the unusual sounds are, you should switch off your appliance and let a professional give it a look. Unless you have the necessary repair skills, you should avoid trying to fix the unit as you will most likely cause more problems than they were originally there.
Freezing up of the heat pump
The heat pump isn’t supposed to freeze under any circumstance; therefore, when yours does it, you have a problem that you should address as soon as possible. Your heat pump will freeze up due to many issues such as technical malfunction, excess moisture, restricted airflow, improper maintenance, and many others.
When your appliance freezes up, you should hire a heat pump repair service Long Beach professional to inspect the unit and find out the reason behind it. As rule of thumb, ensure that the repair professional is experienced enough.
