How Often Should A Heat Pump Be Cleaned?

How Often Should I Clean My Heat Pump? ……….


And does my heat pump need cleaning?………are questions we get asked a lot at Pure Air Cleaning. The Heat Unit filters should be cleaned periodically, about once every month or two, depending on usage and air quality.


The heat pump air filters are easy to access (by opening front cover and removing) and can be done by vacuuming the lint and particles from the filters. If the filters need a more thorough cleaning, they can be removed and washed with warm water and a mild cleaning solution – However, if the filter is a fibre filter, water should not be used on some filters as it can degrade the filter.





How often should a Heat Pump Be Cleaned?

The standard recommendation of a full clean for a Ductless Heat Pump System is between 12 and 18 months. However, this can vary depending on the amount of use and the amount and type of air pollution in your area. We have seen heat pumps that have been used for 2 years that still don’t require a clean (though this doesn’t happen too often!), and we’ve seen systems that are desperate for cleaning after just 3 months!


NOTE: We offer FREE inspection & quote and can show you if yours needs cleaning or not!




- Take a flashlight and look between the louvres (or air vents/grills) at the bottom of the head unit (see pic below) 

- Look into the back and at the ‘blower wheel’. This is a cylinder that runs the length of the machine and spins to distribute the air. Moisture can sit here and more often than not, it is built up with dust, dirt, gunk and often mold.

- If your unit hasn’t been deep cleaned in over a year or more, chances are there is a lot of build up here that needs to be flushed out.

- Take a flashlight and look in-between the grills at the bottom of the head unit. When we perform a Mini-Split Deep Clean we remove all covers, spray soak the coil, and flush all this out to a sparkling shine.

You can also open the cover to the Head Unit and remove the filters. Look at the coil (the metal unit with lots of thin blades/veins) to see if it has dust, particles or mold in-between the blades. This will decrease the efficiency and safety/air quality of the machine.

A full clean will keep your machine running at its top efficiency, save you money on power, eliminates mold and inhibits future mold build up. If the head unit is left uncleaned for too long and starts to develop mold, this will be distributed around your home in the air by the fan.

If in doubt, give us a call or e-mail : and we’ll talk you through checking and even give you advice on how to clean the unit.


If you are unsure, we will come out FREE of charge to inspect your unit and let you know if it needs cleaning!!




Good luck and until next time, breath pure air, stay healthy,
