How often should a heat pump be serviced?

Like any heating system, a heat pump runs best with regular maintenance. The recommended interval is once a year, and there are good reasons not to skip it.

The yearly rule

An annual service keeps efficiency high and running costs low, and is usually a condition of keeping your manufacturer warranty valid.

What gets checked

We check refrigerant pressures, water flow, filters, electrical connections and controls, and clean the unit. Small adjustments here make a real difference to performance.

Grant and warranty compliance

If your heat pump was grant-funded, regular servicing helps keep you compliant. We send a reminder each year so it is one less thing to track.
