How to look after your Heat Pump

Heat pumps need to be maintained regularly and kept clean. By doing this you can ensure they work efficiently and extend the life of your unit. An annual service from us is a great way to keep your Heat pump running efficiently but there are also some basic maintenance checks we recommend you carry out yourself.

There are 3 parts to maintaining your Heat pump – filters, indoor unit & outdoor unit:

Cleaning Heat Pump Filters:

Your Heat pump filters collect a lot of dust and dirt that passes through the unit as it circulates air in your home. This is captured by your filters which need cleaning every few months. It is easy to clean your filters but check your Heat pump manual first – usually you lift the front cover and slide out the filters (you may need a step ladder if the indoor unit is mounted high on a wall).

Remove the filters and spray with a kitchen or general spray cleaner. It is best to do this in the bathroom or take the filters outside. Rinse thoroughly and repeat if you think necessary. It is important not to use any solvents or harsh cleaners. Allow the filters to dry and then replace in your Heat pump.

Cleaning the Indoor Unit

Check the cylindrical fan vanes as well as the Heat pump vanes while you have the filters out. Over time dirt/dust can build up. Remove this using the upholstery brush on your vacuum cleaner to gently suck dirt away. We also recommend giving the outer casing of your Heat pump a gentle wipe over with a damp cloth that has a squirt of kitchen spray (or similar).

If you are running your Heat pump most of the day and for most months of the year (heating & cooling) we would recommend you clean your Heat pump filters 4 times a year. For those using a few months a year and for heating only we would recommend 1-2 times a year. Autumn and spring are good seasons to do a filter clean.

Cleaning the Outdoor Unit

It is really important that the outdoor unit is kept clear of debris, leaves & vegetation. This means airflow to and from the unit is not obstructed. Regularly clear away leaves, twigs, snow and try not to store anything in front of the air grilles. Check the air grilles don’t have anything stuck in them and are not building up dirt or dust – if necessary wipe the outdoor unit casing with a damp cloth.

Inspect the air grilles too for signs of corrosion – rust will build over time and can affect the unit operation. Get in touch with us if you do notice signs of rusting on your outdoor unit fan grilles.

Ideally you should carry out an inspection of your outdoor unit 1-2 times a year (we suggest Autumn & Spring). However it is worth keeping a regular eye on your outdoor unit if your garden has a lot of trees / vegetation close to the unit.
