What Happens During a Heat Pump Service?

What Happens During a Heat Pump Service?

Our deep south winters are cold and our summers can be hot.  Your heat pump works hard to keep your home warm and comfortable throughout the year. But, like any appliance, it needs a little maintenance to keep working efficiently.

We recommend having your heat pump professionally serviced every 12–18 months. Even if you regularly clean the filters yourself, dust and dirt can build up deeper inside the unit, where normal household cleaning can’t reach.

So, what actually happens when you book a heat pump service with Awarua Synergy?

What our technicians do

When our technician arrives at your home, they’ll start by taking a before photo of your heat pump. The indoor unit is then carefully opened up and the necessary parts removed so the technician can access the heat pump coil and other areas where dust and dirt can accumulate.

The service includes:

  • Cleaning the indoor coil using a specialist coil cleaner to remove built-up dirt and grime.
  • Deep cleaning the unit with condenser cleaner, which helps break down stubborn dirt.
  • Cleaning the filters with specialist filter cleaner to help bring older filters back to life.
  • Cleaning the outdoor unit, which receives the same thorough treatment before being carefully hosed down.
  • Rinsing and drying removed parts before everything is correctly re-installed.

Once the cleaning is complete, our technician takes after photos and carries out a maintenance run check to make sure the heat pump is operating as it should.

We’ll also leave a service card so you have a record of the maintenance carried out.

What is not included in a heat pump service?

It’s important to note that a heat pump service is preventative maintenance – it is not a repair visit for a broken heat pump.

Your heat pump needs to be operational when our technician arrives so that we can complete the service and carry out the maintenance run check.

If your heat pump has stopped working, is displaying a fault code, isn’t producing heat or has another known problem, please let us know when you contact us. This may require a diagnostic or repair visit rather than a standard heat pump service.

Not sure what you need? Just describe the problem when you get in touch and our team can help determine the right next step.

Why does your heat pump need servicing?

The filters in your heat pump catch a lot of dust, but they can’t catch everything. Over time, dust and debris can make their way behind the filters and build up on the internal components.

Regular servicing helps keep these components clean and your heat pump in good working condition. It can also identify potential maintenance issues before they become bigger problems.

Cleaning your filters regularly yourself is still important, but a professional service goes much further than a standard filter clean.

How often should you service your heat pump?

For most homes, we recommend a professional heat pump service every 12–18 months.

If your heat pump gets particularly heavy use, or your home has higher levels of dust or pet hair, you may benefit from having it checked more frequently.

How long does a heat pump last?

A well-maintained heat pump will typically last around 10–15 years, although some can continue operating effectively for longer. How long yours lasts will depend on factors including how often it is used, how well it has been maintained, the quality of the original installation and the conditions it operates in.

Regular cleaning and servicing can help extend the life of your heat pump by keeping coils, filters and other components clean and identifying problems before they develop into more expensive faults.

However, there comes a point when replacement can make more sense than another repair. If your heat pump is 10–15+ years old, needs increasingly frequent repairs, has become noisy, struggles to heat your home effectively or is becoming expensive to run, it may be worth considering a newer system rather than continuing to repair it.

Modern heat pumps can also be considerably more efficient than older models, so replacing an ageing unit can improve comfort while reducing the amount of electricity needed to heat your home.

Is your heat pump due for a service?

If you can’t remember the last time your heat pump was professionally cleaned and serviced, there’s a good chance it’s ready for some attention.
