Common heat pump problems

Your heat pump can show various signs of malfunction. Here are the most common problems that require a certified technician.

Heat pump no longer heating or cooling

This symptom often points to a problem with the compressor, the refrigerant or the circuit board. A quick check helps avoid making the situation worse.

Unusual noise or vibration

A metallic noise, a hum or excessive vibration can be caused by a faulty fan, a worn motor or a loose part. Several things can be involved: see our article My heat pump is noisy: what can I do?

Water leak

Water running under the wall unit or around the indoor unit can be caused by a clogged drain, poor condensate drainage or a lack of refrigerant in the system.

Odours or lukewarm air

Unusual odours, or air that stays lukewarm even in cooling mode, can be caused by a very dirty filter or an airflow problem.

Weak or irregular airflow

If air comes out of the vents weakly, it may be a failing motor, a dirty filter, a blocked fan or an electrical problem.

Error codes or indicator lights

If your unit shows an error code, it is a protection mechanism: the unit is signalling that a component must be checked quickly.

Check before placing a service call

The filters

Make sure the unit’s filters are clean. All air conditioning and heating systems have filters that protect the coils from dust and other debris.

The circuit breakers

Check that all the circuit breakers connected to the units are switched on.

The thermostat setting

Make sure your thermostat is set for heating or cooling: set the target temperature colder or warmer than the current room temperature.

The thermostat itself

Check that your thermostat or remote control is on and working properly.
