Heat pumps are a great energy-efficient way to heat homes during mild Atlanta winters. Like any other heating and cooling system, as heat pumps kick into high gear for the winter they can run into performance malfunction issues.
If you run into any of the common heat pump issues below, try these heat pump troubleshooting ideas. If it’s more than DIY, call the pros at Estes Services to fix the problem.
Heat Pump Troubleshooting Issue: Ice or Freezing
If light ice remains on your heat pump for more than half a day, you shouldn’t ignore it. An iced-over heat pump could turn into a costly problem.
Ice can damage the heat pump’s fan blades and prevent heat from transferring between the refrigerant and the outside air. This makes it hard for the condenser to operate and leads to severe damage.
To melt the ice without damaging your heat pump, first, try running the system’s defrost cycle. On some units, this cycle turns on at timed intervals or when the unit detects frost.
If your defrost cycle doesn’t work, it could mean it needs a minor adjustment or repair. If this is the case you should call a pro to help. In the meantime, try these heat pump troubleshooting ideas:
- Replace and clean the air filter if needed.
- Gently remove ice from the unit, if possible. NEVER use a sharp object to chip away the ice, as you can damage the heat pump’s fan coils.
Heat Pump Troubleshooting Issue: No or Cold Air
If you’re feeling no air circulation in your home, first check you have a clean filter. Second, verify all your vents are open and free from obstructions so warm air can move freely.
Even in rooms you rarely use, it’s important to keep vents open. Closing them creates unwanted pressure within your HVAC system and causes duct leaks, or worse, system failure.
If neither of the above seems to be the problem, your heat pump may have a malfunctioning blower motor, frozen evaporator coil or collapsed ductwork. If you feel cold air when you want warm air, your heat pump could be in defrost mode.
This is a normal occurrence if you don’t have a supplemental heating system, such as heat strips. After about 15 minutes, the defrost cycle should complete and the heat should return.
If cold air does not stop, a problem may be present within your system. In either of these cases, you should call the HVAC pros at Estes Services. They will help you with your heat pump troubleshooting needs all the way from diagnosing the issue to making the repair.
Heat Pump Troubleshooting Issue: Frequent Cycling
Your heat pump cycles on and off throughout the day to keep your home at a comfortable temperature. If you notice your unit turns off and on too frequently, it may be a sign your heat pump is overheating either because of a clogged filter or malfunctioning blower.
Your first heat pump troubleshooting step for this common issue is to clean or replace the filter. If this doesn’t work, check the thermostat, which may require recalibrating.
Heat Pump Troubleshooting Issue: Constantly Running
Heat pumps run longer and produce less heat than furnaces, which make them an ideal, cost-effective heating option for mild Atlanta temperatures. In fact, the average energy bill for a home heated with a heat pump is about half of that for a home heated with electric resistance heating, according to the Department of Energy.
It’s common for your heat pump to run constantly in freezing temperatures, but if it’s above the mid-30s and your heat pump still won’t turn off, it may be a sign of any of the issues below:
- Leaking refrigerant, frozen outdoor unit or compressor problem.
- You have an undersized unit not equipped to heat your home.
- Your home lacks adequate insulation, causing too much heat loss.
- A poorly running system due to lack of maintenance.
