Heat pump maintenance and warranties

What a service covers

• Checking refrigerant pressures and for leaks (by an F gas certified technician)
• Cleaning the outdoor unit's coil and fan
• Checking the system's water pressure, filters and antifreeze
• Checking controls, settings and the hot water cylinder's safety valves

What you can do yourself

• Keep leaves, snow and plants at least 30 cm clear of the outdoor unit
• Clean the magnetic filter if your installer shows you how
• Leave settings alone once they're tuned: constant fiddling costs money

Warranties

Manufacturer warranties often depend on an annual service by an approved installer, so keep your service records. The workmanship warranty covers the installation itself: leaks, wiring, a badly sized system, and should be in writing before you pay the final stage.
