Air Source Heat Pump Servicing & Maintenance
Heat pumps need less maintenance than boilers, but not none. A yearly service protects efficiency and your warranty.

An air source heat pump pulls heat from outside air and lifts its temperature with a refrigerant circuit and compressor, to serve radiators, fan convectors, underfloor heating and hot water. When it's set up and looked after properly, it's one of the most efficient ways to heat a building.
Most manufacturers make annual servicing a condition of the warranty. Our service covers the refrigerant side, the water side and the controls, and finishes with an annual service certificate.

FAQ
Questions we get asked
What can we do between services?
Keep the evaporator and air inlet clear of leaves and plants, check the system pressure gauge now and then, and avoid big thermostat swings.
How often should our equipment be serviced?
At least once a year. Ideally heating in autumn and air conditioning in spring. Oil-fired equipment really should be cleaned and serviced every year.
Why service if nothing is wrong?
Better reliability, problems caught early, lower running costs, longer equipment life and a safer building. It's also usually a legal requirement.
