Heat pump maintenance, troubleshooting and repairs

Domicile: Joensuu

Service area: Eastern Finland


When is maintenance worthwhile?

It is recommended to have an air source heat pump serviced by a professional every 1–3 years – for example in spring or autumn before the periods of heaviest use. This ensures that the pump heats in winter and cools in summer without surprises. Maintenance is carried out throughout the year.

Possible malfunctions may be caused, for example, by a dirty indoor unit, clogged filters, a refrigerant leak or even loose electrical connections – expert help is available to find out what is going on.

The most common signs that maintenance is due

  • The interior of the indoor unit can be inspected through the air outlet using a flashlight. When the unit is switched off, the flaps can be opened manually; they will automatically return to their original position when the unit is started. If it is clearly dirty, maintenance is due.

  • Reduced heating or cooling performance.

  • Unusual noises or vibrations.

  • Unpleasant odor from the indoor unit.

  • Water flooding from the indoor unit onto the floor.

  • The pump does not start or operates intermittently.

An air source heat pump is an electrical device that should not be left to fend for itself

FAQ: "Do they really need maintenance?"

In July 2019, a row house in Joensuu was destroyed due to a faulty air source heat pump, a stark example of why maintenance should never be neglected. The fire started in the outdoor unit and spread like wildfire; the roof collapsed 10 minutes after the fire ignited. Fortunately, there were no personal injuries, but many homes burned to the ground.

Loose connection = FIRE HAZARD

Vibration and temperature fluctuations over the years can loosen electrical connections in an air source heat pump. This can cause sparking and an electric arc, which in turn can lead to a rapidly spreading fire. A loose electrical connection is a very common issue that is frequently encountered and fixed during maintenance visits.
