When Was The Last Time You Serviced Your Heat Pump?

Are you reading this whilst sitting in the comfort of your home? Depending on where you are in the country, the outside temperatures, especially during the night, are not exactly sitting in the sub-tropical region of degrees! If you are one of New Zealand’s fortunate home owners who have a heat pump for home heating, when was the last time you requested a service for this appliance?

Hopefully, you can answer that question instantly. But if you can’t, you might have a problem developing on your hands.

What happens if you don’t service your heat pump?

The short answer is that your heat pump will become less efficient and its lifespan could be affected. Keeping your heat pump running efficiently will allow you to benefit from its warmth whilst keeping the running costs low.

If dust and dirt accumulates in the filters and in your heat pump then you also can run the risk of having mould and mildew develop and grow in the inner workings. These spores can then be distributed through your home every time you turn your heat pump on.

Purchasing and installing a heat pump is an investment in both your home and you and your families’ health. Because it is an investment, it makes sense to protect your investment and the best way to do this is by requesting a regular service for it.

One of the simplest things that you as a home owner can do for your heat pump is to regularly clean the filters. When your heat pump was installed, the installer should have shown you what to do, but if you have moved into a home where a heat pump was already installed and you have never been shown how to clean a filter, it is super simple! Most heat pumps have a front cover, remove this and you will find your filters. The easiest way to remove the dirt is to use your vacuum cleaner with the brush attachment in place. You can also wash the filters by removing them and washing with water, making sure the water is not hotter than about 50°C and then drying them in the shade.

If you clean your filters yourself then you can organise to service your heat pump just once a year. Usually, the busiest times of the year for heat pump servicing is in spring and autumn. Why? Because people either like to have their heat pump work at its hardest during summer when it can pump cool air around your home or in winter when it pumps warm air around your home to keep you toasty.

Heat pump servicing should cover service items like the:

  • Cleaning of filters
  • Cleaning of vanes
  • Cleaning of grills and outer covers
  • Checking both indoor and outdoor units ensuring they are level; mounts are intact and checking for unusual sounds or vibrations
  • Checking fan blades or scrolls and clean as required
  • Checking for leaks around the flare fittings
  • Checking condensate line and test for drainage
  • Checking all electrical wiring including the terminals
  • Checking and testing start/stop sequence and heating/cooling changeover
  • Checking both evaporator and condenser coils
  • Test run and check air on and air off temperatures

Your heat pump technician will be able to give you a breakdown of what their service will cover before they embark on servicing your heat pump.

Usually, an annual service is all that is required to keep your heat pump running at its optimal performance level. However, sometimes miscellaneous issues can crop up – you don’t have to wait for the next annual scheduled service to call a technician.

In fact, the sooner you get your unit looked at the sooner you can rest easy knowing that your heat pump will continue to work well, is operating efficiently and not costing you more than necessary.
