Cleaning the air source heat pump filter is easy and only takes a few minutes. The easiest way is to use a vacuum cleaner's small nozzle. If the filter has not been cleaned for a while or is very dusty, it can be washed gently. The filter must be allowed to dry thoroughly before reinstallation.

Your heat pump installer or maintainer can show you how to clean the filter. Tutorial videos are also available online.

If the heat pump is only used for heating, maintenance could be carried out before the start of the winter. If the unit is also used as a cooler during the summer, maintenance could be done in the spring.

A properly maintained air source heat pump lasts longer and operates in a mode where there is a balance between heating capacity and electricity consumption. However, it should be noted that the efficiency of older devices decreases over time.
