Are you experiencing the frustration of your heat pump not cooling your home? It’s a common problem faced by homeowners that can arise due to several issues. Grove Heating & Cooling discusses some of the common problems which are responsible for a heat pump not cooling and provides troubleshooting solutions to get your heat pump running efficiently again.
The thermostat is the most vital component of the HVAC system as it controls the temperature in your home. A malfunctioning thermostat can sometimes prevent the heat pump system from cooling properly. If your thermostat is faulty, it may not send the correct signals to the heat pump, resulting in an improper cooling cycle.
This issue can often be resolved by simply replacing the thermostat. However, if you’re unsure of how to do this, it’s best to contact a professional heating and air conditioner technician to inspect and replace the thermostat.
Refrigerant is the medium that’s responsible for transferring heat from inside to outside and vice versa. If there’s a refrigerant leak, your heat pump will struggle to maintain a consistent temperature, which can cause the system to run continuously or inadequately cool your home. If you suspect a refrigerant leak, it’s crucial to have a professional repair the leak and refill the refrigerant to the recommended levels. This will ensure that your heat pump functions optimally and efficiently.
Heat Pump Stuck in Heating Mode
Heat pumps can also get stuck in heating mode. If this happens, your heat pump will blow hot air instead of cool air, which can make your home uncomfortable during the summer. The culprit of this problem can be a faulty reversing valve. The reversing valve is responsible for defrost cycles and switching the heat pump from heating to cooling mode. Contact an HVAC technician to diagnose this issue and replace the valve if it’s defective.
Frozen coils can also cause your heat pump not to cool your home efficiently. When the coils freeze, they prevent air from passing over them, resulting in reduced airflow and inadequate cooling. A common cause of frozen coils can be the buildup of dirt and debris, which restricts airflow over the coils. Regular maintenance, including air filter changes and coil cleaning, can help prevent frozen coils.
To defrost your heat pump coils, follow these steps:
- Turn the cooling off at the thermostat and turn off the heat pump system’s circuit breaker.
- If the indoor coils are frozen, turn on the system’s fan at the thermostat to help blow warm air over the coils. If the coils in the outdoor unit are frozen, use a garden hose to melt ice away with water. Never use any kind of tools or other objects to chip away ice from the coils as this may damage the coils.
- Troubleshoot the reason why your heat pump is freezing up:
- Check the air filter and replace it if it is dirty.
- Clear away the debris that has collected on the exterior of the heat pump.
- Fix leaky overhead gutters.
Do not turn the heat pump back on until the coils have thawed completely. If your heat pump coils continue to ice up, turn the system off and call for heat pump repair.
Blower Motor Issues
If the blower motor isn’t working correctly, the heat pump won’t be able to circulate air to cool your home. Common causes of blower motor malfunctions include dirt buildup or a faulty motor. If you suspect a blower motor issue, contact an HVAC professional to inspect and repair the motor.
