Heat pumps should run for 10 to 15 minutes at a time unless the temperature in Thurmont, MD, changes drastically. If yours cycles more often and for longer, there’s a problem. Read on to learn why your heat pump won’t stop running.
Dirt-Covered Coils
Your heat pump comes with two coils: the evaporator coil in the air handler and the condenser coil in the compressor. In cooling mode, the former takes heat from your home and the latter releases it outside. If either coil gets covered in dirt or dust, it fails to produce cool air and so forces the systemto run without ever reaching the set point.
Low Refrigerant Levels
If the problem doesn’t lie with the coils, it may lie in a lack of refrigerant. This chemical courses through the heat pump to absorb and release heat. But if a previous service technician didn’t charge it sufficiently, or if the refrigerant line leaks somewhere, then lukewarm air will result. This naturally prevents the system from achieving your desired temperature no matter how long it runs.
An Undersized Heat Pump
Heat pumps have a specific heating/cooling capacity, and if your home is too large or too small for your system, it won’t ever run efficiently. In this case, an undersized heat pump, because it lacks the power to cool your whole home, will run excessively long. A new HVAC system installation provides the only viable solution.
