When your heat pump suddenly stops working, the best thing to do is, of course, to call a repair service. Specifically, a heating repair service, so they can send someone to come in and take a look at the heating system in question.


After all, a heating pump is complex in nature and an untrained person will not be able to spot the source of the problem. Once the contractor has arrived, you will be asked a series of detailed questions so be prepared to take some time out of your day to assist the contractor in their repair services. These are the most commonly documented heat pump malfunctions:


Outdoor Compressor And Fan Have Stopped Working


When the outdoor unit stops working, it is often due to a tripped breaker circuit, problems with the wiring, a blown-out fuse, a bad transformer, or an overloaded compressor. When this happens, you should pray that all you need is a furnace tune up, because the worst-case scenario would be the need for a whole new heat pump.


Humming Heat Pump That Won’t Start


The majority of the time, this is caused by a malfunctioning part, i.e. a bad start capacitor, compressor bearings, or compressor motor. Sometimes the cause will also be electrical problems. Regardless, you will likely need to replace the heat pump, unless the problem is electrical in nature, in which case the contractor may have a chance of saving it.


Outdoor Compressor Won’t Work


So, the compressor doesn’t work but the fan does. This is often due to improper phasing, poor voltage, a grounded compressor motor, or because of a bad capacitor. When it comes to such problems, it will be up to your contractor to determine whether your system needs replacing or if a repair job is sufficient.


Outdoor Pump Or Fan Aren’t Working


When there is an issue with the pump or fan relay, an issue with the timer, or a fault in the motor, then there is no getting around replacing the pump. However, if the issue is electrical, a straight up rewiring may get the job done.


However, don’t try to do it all on your own but call in the AC Repair experts in Philadelphia. They understand all aspects of the pumps and HVAC units and will be able to do what is necessary which will make sure that your unit is working again.


Indoor Fan Has Stopped Working


When there is a malfunction with the motor or transformers, you will not get around purchasing a replacement. However, if the problem is a blown fuse, bad circuit, or an issue electrical in nature, you will be fine with getting a repair job done.
