The importance of heat pump maintenance and servicing

Caring for your heat pump is easily and often discounted as a ‘nice to have’ rather than a necessity. However, they are an asset worth something to the value of your home and your own personal comfort so therefore worth taking care of.

Longer lifecycle

Like anything with a motor, regular maintenance and servicing is important for your heat pump to keep it running as well as possible for as long as possible.

Enhancing efficiency

Efficiency should be a key driver to get your heat pump serviced regularly, after all, isn’t efficient heating why you had it installed? When it’s not running at its peak it’s costing you more in energy consumption.

Health benefits

Regular heat pump servicing helps the filters keep doing their job of removing bacteria and odours from the air in your home.

Improved comfort

If your heat pump isn’t at its peak and heating or cooling proficiently it’s directly impacting your comfort levels.

When to service

A good brand, serviced properly, can last anywhere up to 15 years. Never having it serviced could knock at least 5 years off that or at least ensure it’s performing poorly for a large portion of it’s lifecycle.

Your heat pump should be serviced before you really need it so pre-winter and, if you use it for cooling, before the peak of summer.

If you notice your power bills have increased without an obvious reason it could be your heat pump is not running well and needs a service.

I clean my heat pump filters, I don’t need a service

We hear this a lot and it’s important to know that cleaning and servicing are quite different. Filter cleaning is basic maintenance and good on you for doing it often. However, servicing also tends to the mechanical operation of both the indoor and outdoor units.

Things you can do yourself

  • Check your manual and follow any instructions it gives on maintenance and cleaning.
  • Clean supply and return grilles/louvers with a damp cloth (these are the fins that swing back and forth to move the air) and make sure they're not blocked.
  • Filters can usually be cleaned simply by vacuuming or wiping with a damp cloth. During times of heavy use you may want to wash them in warm soapy water, leave to dry and return to the unit.
  • To clean the outdoor unit, gently hose it down to remove dirt and a brush to clear away cobwebs and bits of plants and leaves that have gathered and could block the coil or drain.


  • If your heat pump won’t switch on, check the remote control batteries. It they’re ok, check the fuse in your fuse box.
  • If the temperature is right but the air flow is weak check the filters aren’t clogged with dust and in need of cleaning.
  • Check your manual's troubleshooting section and follow any instructions.
  • If you don’t see any improvement after following these tips it’s time to call in HPAC.
