Heat Pump Issues
Many people ask, what exactly is a heat pump? Heat pumps are devices that heat from an initial source to a destination called a “heat sink” by using mechanical energy. In layman’s terms, heat pumps absorb heat from a cold space and release it to a warmer one. Therefore, a heat pump can actually be used for cooling, keeping a device (or space) and its contents cold. When a heat pump is used for heating, it works in the opposite direction, by releasing heat into the conditioned space rather than the surrounding environment.
Heat pumps are highly recommended for heating homes because they are three or more times more efficient than electrical heaters. If you want to keep your home warm and save money on your power bill, installing a heat pump is an excellent decision. The need for heat pump repair can stem from a variety of internal and external sources. Whether the problem is from your heat pump malfunctioning, or from an external source, Superior Mechanical can help you diagnose and solve your problems with professional heat pump repair service. You don’t want to be left shivering or sweltering when you experience an unforeseen problem with your home’s heat pump. Some common issues and explanations for problems that you may encounter with a heat pump:
My heat pump won’t turn on:
If your heat pump does not turn on, it means that there is no power being sent to the heat pump. This means that there is the possibility that it is an electrical problem. It may be a tripped circuit breaker, or blown fuse, which can be relatively simple fixes. Electrical problems may also stem from wiring problems or loose terminals, in which case it is best to have it worked on by a professional, as electrical work can be incredibly dangerous if you are not completely familiar with what you’re working on.
The heat pump may also not be turning on because of a problem with a mechanism of the heat pump. A bad transformer, or bad heat pump contactor may be the culprit. You may be dealing with compressor overload which may be caused by obstructed outer coils, or a high/low pressure cut out that is open, which can be caused by low refrigerant, which is usually an indication of a larger problem. Another common reason for a heat pump not turning on is due to a problem with the thermostat, which causes the thermostat to not send an “on” signal to the heat pump.
My heat pump won’t start, but I hear a humming noise:
If your heat pump is not starting, but you hear an electrical humming noise, the likely culprit is a bad start capacitor. If it is a bad capacitor, it is important to get it replaced quickly to save it from damaging the motor. If not the start capacitor it may be caused by a problem with the compressor motor or even the compressor bearings.
A heat pump not starting accompanied by a humming noise may also be caused by an electrical problem within the heat pump.
My outdoor fan will not start:
If your outdoor fan does not start, it may be an electrical problem causing power not to be sent to the outdoor fan. If it is not electrical then you may be dealing with a bad fan or pump relay, or even a broken defrost switch, which can cause ice to accumulate quickly, making it impossible for your fan to start. A bad timer may also be causing the fan to fail to start. Your fan motor may also have a serious problem that needs diagnosing by a professional heat pump repair service.
My indoor fan will not start:
For an indoor fan that does not start, It would be best to first check to see if a circuit breaker has been flipped or if a fuse has been blown, causing it to not receive power. Other electrical problems, such as faulty wiring may be to blame. It may also be caused by a bad motor or transformer, causing a critical problem that causes the fan to not run requiring a professional heat pump service. The thermostat may not be sending the “on” signal to the fan because of a problem with the thermostat.
