Auckland Heat Pump Repairs and Maintenance

Our brand philosophy doesn’t stop at simply installing something for you. A heat pump is like a refrigerator, once in a while we need to take everything out and give it a good clean. Our heat pumps are made to provide you with years of comfort, and every once in a while we need to give something back. The best thing you can do for your heat pump is to make sure it’s serviced and well maintained. Keeping up with these things will help keep the running cost down and extends the life of your heat pump.

To ensure your heat pump stays healthy and cost-effective to run your heat pump must be clean and free from mould. If heat pumps do not regularly get cleaned and are allowed to collect dust, the dust can clump, block the fins for heat transfer and absorb moisture which can lead to mold growth. When mould growth is allowed to fester it may affect the health of the occupants meaning you and your family could seriously sick.

The clumps of dust that stick to the fins and blower wheel can also accumulate in the drainage tray and make it look like the heat pump is leaking. If no one notices the leak and is accidentally allowed to continue the resultant water can damage the wall paint, plasterboard, skirting, flooring, and the wood behind your wall. Moisture trapped in the wall and flooring can lead to mold growth if it is not allowed to dry properly. All this can sound really scary but it is unlikely you would not notice a puddle of water under your heat pump.

There are a few simple steps you can do yourself to maintain the health of your heat pump and with very few tools and equipment. The tools and equipment you need to do a basic clean:

  1. A ladder tall enough to safely reach the heat pump
  2. Safety goggles and dust mask
  3. Some old towels to protect furniture or flooring directly under the heat pump
  4. Outdoor hose long enough to reach the outdoor unit of the heat pump
  5. A small pressure sprayer (1-2Litres) – we strongly recommend getting a good quality sprayer. I personally only use the brand “solo” as they are made extremely well and make the world of difference when a sprayer is needed.
  6. Disinfectant concentrate to mix with water
  7. Small brush from a dustpan set

The Last 3 things are trade secrets that can help our customers getting a deeper clean.

  1. Set up some old towels directly under your heat pump
  2. Position the ladder so you can comfortably work on your heat pump
  3. Put on your safety goggles and a dust mask
  4. Depending on the brand of your heat pump you will see 2 grooves either on the side or on the bottom of the heat to pull the face of your heat pump up and lift it out of your way.
  5. Remove the 2 lint filters and give them a good clean, either with water or using a small brush outside to physically remove the lint.
  6. Go outside to your outdoor unit and switch the isolation switch to the OFF position
  7. Prepare your pressure sprayer and make up to 1 litre of disinfectant solution as per the instructions on the disinfectant label. Pump your sprayer so it is fully pressurized and adjust your sprayer nozzle to an appropriate spray pattern to be able to lodge off any surface dust or small dust clumps. Do not try this if an excessive amount of dust clumps or a thick layer of dust is present. At this late stage a professional should be called to clean properly clean this.
  8. Spray the small metal fins only in your heat pump being careful not to damage the fins with the sprayer head. Adjust your sprayer head if need be, to clear away any dust.
  9. Stop if you see excessive water dripping out.
  10. Refill the pressure sprayer with 1 litre of clean water, and re-spray fins to flush out the residual disinfectant
  11. Dry any water that has landed on the outside of your heat pump and allow lint filters and heat pump to air dry
  12. Once dry, replace the filters and shut the heat pump cover.
  13. Now that the indoor unit of the heat pump has been cleaned, connect your hose and go towards your outdoor unit.
  14. Clear any rubbish, plants, or weeds from the outdoor unit to ensure good airflow.
  15. Using your hose give the fins on the outdoor unit of the heat pump a good spray.
  16. Switch the isolation switch back to the ON position


If there is a thick layer of dust on the fins or blower fan, there is a high likelihood that there is already a significant amount of mould in the heat pump. Not only is the heat pump costing you far more power to run but they may be health consequences that you are unaware of. Keeping up with a professionally supplied service plan is important for anyone who has cancer and or taking medication such as immune-suppressants, steroids (corticosteroids), or cancer-fighting medicine. People with asthma, COPD, organ transplants, rheumatoid arthritis, or IBD are more vulnerable to mould spores and should put their health first over the inconvenience of arranging an annual service.
