How long should a heat pump run in winter?

Typically, a heat pump should cycle two to three times an hour. The heat pump should stay on for 10 to 20 minutes during the cycle. However, during cold outside temperatures (below 30-40 degrees), a heat pump will constantly run to maintain the home temperature.

At what temp does a heat pump not work?

Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.

Do condenser fans always run?

Condensor Coils

As a result, your condenser will have to work harder to keep things cool, thus causing the fan to run continually.

Faulty Thermostat: If both the fan and either the cooling or heating system are running unexpectedly, you may have a faulty thermostat. Broken Relay Switch or Short Circuit: If only the fan is running, there may be a broken relay switch preventing the settings you enter on the thermostat from being sent to the fan.
