It’s frustrating when your heat pump in Montreat, NC, can’t seem to stay on. Let’s cover some reasons your heat pump might be shutting off prematurely.

Thermostat Issues

One of the simplest reasons for short cycling is thermostat issues. Low batteries can cause the thermostat to incorrectly read the temperature. There could also be a problem with the wiring, or the thermostat may be failing due to age.

The average lifespan of a smart thermostat is 10 years. That means that it could fail years before the rest of the system would need replacing. During an HVAC maintenance visit, our service technicians check the thermostat to make sure it’s reading correctly.

Thermostat placement is also a key culprit in incorrect temperature readings. If it’s too close to doors, windows or heat-generating appliances, the thermostat may not be able to read the indoor temperature correctly.

Frozen Evaporator Coil

A frozen evaporator coil can also cause a heat pump to short cycle. This is often due to inadequate airflow.

An easily preventable cause of poor airflow is a clogged air filter. We recommend cleaning or replacing your air filter every one to three months. However, if you have pets or live in a dusty environment, you may need to change the filter even more often.

If furniture or drapery is blocking your air return vent, this can also reduce the airflow and result in frozen coils. Don’t place furniture or other obstructions within 1 foot of the vent.

Improperly Sized Unit

An oversized heat pump can result in short cycling. The system will bring your space to the set temperature too quickly, causing the system to shut down soon after turning on. When this happens, you’ll notice hot and cold spots around your home.
