A heat pump is a great heating and cooling option for homeowners in the southeastern part of the country. It provides comfortable temperatures in your home year-round, however without proper maintenance, malfunctions will happen more often because the unit doesn’t get a break from one season to the next. Between heat pump maintenance calls, you might experience various issues with your heat pump. Here are three common heat pump problems and methods to troubleshoot them yourself or with the help of an Estes Services professional.
Heat Pump Troubleshooting #1
Your heating and cooling system experiences some degree of frost or even light ice forming on the outdoor unit during the winter. Your heat pump will go into a defrost mode every so often to remove the frost. However, if the entire unit is covered in snow and ice, the top of the unit has a heavy layer of ice, or if the coils are surrounded by ice, you have a major problem.
When ice forms on your coils or unit, it prevents heat from transferring between the outside air and the refrigerant, hampering the operation of the heat pump. Below are some troubleshooting tips if your outdoor heating and cooling unit is frozen:
- Check for leaking gutters dripping water onto your unit and stop the leak
- Remove any snow or other debris blocking the airflow of your unit and
- Use water from a hose to melt ice build up.
If the issue isn’t from a water leak or snow blocking air flow, the problem may be more serious. Contact a licensed technician at Estes Services to have your heating and cooling system inspected. The defrost mode may not be working due to faulty relays, sensors or controls. It’s possible you have a failing fan or it’s completely dead and needs to be replaced.
If your heat pump is frozen during the summer, call Estes Services immediately! Summer icing is not normal and indicates a serious problem, such as a refrigerant leak, clogged filter or dirty coils.
Heat Pump Troubleshooting #2
A heat pump will continuously run while trying to reach a low-temperature setting during a heat wave. Before you call for service on your heat pump, check the thermostat settings. Your heat pump might be performing non-stop due to your thermostat sending incorrect information to your heating and cooling system. If your thermostat settings are correct, you might have a bigger problem on your hands. Call Estes Services to schedule service on your heat pump before the problem escalates.
It’s common for your heat pump to run regularly during the winter. However, if the temperature is above the mid-30s and it’s still running continuously, there is a problem. The best way to deal with an overactive heat pump in the winter is to call an HVAC expert. You could have a serious problem, such as a refrigerant leak, frozen outdoor unit or compressor issue.
Heat Pump Troubleshooting #3
While your heat pump is operating in heat mode, a common problem is cold air blowing out of your system. Easy troubleshooting suggestions include:
- Check to make sure your heat pump isn’t accidentally switched to a/c mode
- Check your outdoor unit to make sure it’s not iced over.
If neither of these solutions is the answer, then the problem needs to be addressed by a professional. Valve problems, refrigerant charge issues or compressor malfunctions are the likely cause of your heat pump blowing cold air during the winter months. With the help of our skilled and knowledgeable technicians, Estes Services will diagnose the problem and resolve the issue quickly.
