It takes 10 to 15 minutes for the average ducted heat pump to cool a home in Webster Groves, MO. Anything shorter than this, far from being a sign of efficiency, is a sign of a malfunctioning unit. Here are some of the most common reasons your heat pump won’t stay on or short-cycles.
Overheating From a Clogged Filter
If you don’t replace the air filter in your return vent approximately every three months, the dirt and debris on the filter will obstruct airflow. This will stress the blower motor and make it overheat, forcing the system to shut down as a safety measure.
Overheating From Dirty Coils
Dirty evaporator and condenser coils can also cause overheating. The outdoor unit, called the compressor, is especially prone to getting dirty. However, a professional technician could clean it for you as a part of annual maintenance.
Faulty Thermostat Sensors
Your HVAC technician will also calibrate your thermostat sensor as part of your system maintenance appointment. That way, the sensors can correctly measure the indoor temperature and tell the heat pump to shut down once it reaches your set point. An uncalibrated thermostat may think the home is cooler than it is and tell your system to shut down before it’s actually cool; hence the short cycles.
An Oversized Heat Pump
If your heat pump is too large for the size of your home, this can also interfere with how long it operates. A system that’s too big and powerful for a home will tend to start and stop running quickly or short cycle. In such a situation, there is not way to fix it except with a new AC installation so that you can get a system that’s the correct size.
