If you’re having trouble with your heat pump and it’s not running like it should, there are a few factors you can check before calling for expert help. Learn five common problems homeowners typically experience with heat pumps, and what you can do about them.
The unit won’t run
Significant problems with heat pump components may be contributing to the problem, but check these factors before calling for emergency service:
- The thermostat setting – Is it set higher than the indoor temperature reading?
- The power – Are the circuit breakers on? Have any fuses blown?
The system isn’t heating properly
If the air coming out of the registers feels cooler than normal, check:
- The thermostat – Try increasing the setting and wait to see if the air warms up.
- The registers – Are they open, allowing maximum air to flow into each room?
- The filter – A dirty air filter could compromise the capacity of the heat pump to generate heat.
- The coils – If it’s been awhile since you had the system cleaned, dirt buildup on the coils can greatly decrease the performance of the heat pump.
The unit freezes up
Frozen coils aren’t normal. A small amount of frost on the coils is okay and normally removed by the defrost cycle. If the system freezes up, however, it’s likely due to low refrigerant or airflow problems. These are best left to the professionals.
The heat pump cycles on and off frequently
Frequent cycling is generally caused by overheating. Components that may contribute to this problem include:
- A dirty filter – Replace the filter and see if the problem resolves itself.
- A malfunctioning blower or improperly calibrated thermostat, among others, which require an expert.
The blower isn’t running
When the blower won’t cycle on, check the thermostat. It should be set to “on.” If the furnace blower doesn’t cycle on, the system’s limit switch is probably faulty.
Most heat pump problems require professional assistance, although it’s generally safe for homeowners to check the air filter and thermostat settings first. Apollo Home Heating, Cooling and Plumbing has served homeowners in greater Cincinnati since 1910. Contact us today. We’re happy to help.
