Why Is My Indian Trail, NC, Heat Pump Short-Cycling?

Short-cycling refers to what happens when your heat pump turns off before getting your Indian Trail, NC, home to the desired temperature. There are several possible causes for heat pump short-cycling.

Dirty Air Filter

A dirty air filter is the culprit for many common heat pump problems, including short-cycling. When you notice a problem with your system, start by checking to see if your air filter is dirty. Replacing a filter is an easy task that can quickly solve the short-cycling problem.

Refrigerant Leak

Your system uses refrigerant to absorb heat from one area and transfer it to another. When there’s a refrigerant leak, the system tends to freeze, which causes it to turn off prematurely.

The first test for a refrigerant leak is simply testing the refrigerant pressure on both the high and low sides. This test is part of routine maintenance that the experts recommend for your system every spring.

Thermostat Issue

There are two reasons your thermostat may read the air’s temperature inaccurately and cause the system to short-cycle. First, it could be an improperly placed thermostat that’s in direct sunlight or too close to a supply vent. Second, it could be an old thermostat with faulty sensors that simply needs a replacement.

Heat Pump Is Too Big

If the heat pump’s oversized for your home’s needs, it’ll short-cycle due to freezing the system. This can stem from the installation, but can also happen if you’ve renovated your home and reduced the service area. Have a qualified service technician perform an HVAC load calculation for your home and evaluate your system’s size.
