On an average summer day in Raeford, NC, a heat pump should cool a home in a cycle of 10 to 15 minutes, two to three times an hour. It shouldn’t run all the time. Long cycles can mean that a heat pump has dirty coils, low refrigerant, a faulty thermostat or a blowing capacity that is too weak for the home.
Dirt and Grime on the Coils
The evaporator and condenser coils of your heat pump get dirty over time, and this build-up will prevent the effective transfer of heat out of your home. Room temperature air will come from the registers, and the system will run continuously without reaching your set point. As a part of maintenance, we can clean both the condenser coils and compressor.
A Refrigerant Leak
Your system can not cool your home if it’s low on refrigerant, and low levels are almost always because of leaks in the refrigerant line. This will require immediate attention because the refrigerant is a toxic chemical. A skilled professional can fix leaks and replace refrigerant.
Faulty Thermostat Sensors
Maybe there’s nothing wrong with the heat pump, but the thermostat receive the indication that it has already reached the set point. This happens when the thermostat’s sensors lose their calibration.
An Undersized System
Heat pumps have a specific blowing capacity. A heat pump that is too small for your home will run continuously and likely leave the rooms farthest from the air handler too warm. This can happen if you have done home renovations or added an addition that exceeds your HVAC system’s capacity.
