How to clean a heat pump yourself?
An air-to-air heat pump moves large volumes of air through the system every day. With the air come dust, pollen, pet hair, and other small particles. Over time, these can accumulate in the filters and reduce heating performance. Fortunately, some maintenance is easy to do yourself. Regular cleaning can provide better heat, lower electricity use, and more stable operation.
In short
- The filters in a heat pump should be cleaned every 3-4 weeks
- Dirty filters can reduce heating performance significantly
- Cleaning normally takes only a few minutes
- Regular maintenance can improve air quality and reduce electricity use
- Simple filter cleaning can improve comfort and reduce operating costs.
Why should you clean your heat pump?
A heat pump works by drawing air through the indoor unit. As air passes through, dust and particles are captured by the filters.
If the filters become clogged, this can lead to:
-
lower heating performance
-
higher electricity use
-
more noise from the heat pump
-
poorer indoor air quality
That is why most manufacturers recommend cleaning filters regularly.
How often should a heat pump be cleaned?
How often you should clean your heat pump depends on usage and the indoor environment.
As a general rule, the following is recommended:
-
clean filters every 3-4 weeks during the heating season
-
clean more often if you have pets or high dust levels at home
If the heat pump is used as the main heating source, filters often get dirty faster.
How to clean your heat pump yourself
Cleaning a heat pump is simple and usually takes only a few minutes.
1. Turn off the heat pump
Before you start, turn the unit off. This makes cleaning safer and easier.
2. Open the front cover
The front cover on the indoor unit can usually be lifted gently. Behind it you will find the filters.
3. Remove the filters
The filters can be removed by gently sliding them out of their tracks.
4. Vacuum the filters
The easiest method is to vacuum the filters using a soft brush attachment.
If the filters are very dirty, they can also be rinsed in lukewarm water.
5. Let the filters dry
If you rinse the filters, they must be completely dry before you put them back.
6. Reinstall the filters
When the filters are clean and dry, place them back in the indoor unit and close the front cover.
What should you not do yourself?
Although filter cleaning is simple, some parts should be cleaned by professionals.
This includes:
-
fan wheel
-
heat exchanger
-
drainage system
-
outdoor unit
These parts require specialized equipment and experience to clean correctly.
Signs that your heat pump needs service
Even with regular filter cleaning, your heat pump may still need professional service.
Typical signs include:
-
the heat pump provides less heat
-
there is odor from the indoor unit
-
the heat pump makes more noise than before
-
airflow is weak
In these cases, a more thorough cleaning of the indoor unit may be needed.
Cleaning gives better performance
A clean heat pump operates more efficiently. When airflow is good and filters are clean, the unit can deliver more heat using less electricity.
This can contribute to:
-
better heating in the home
-
lower electricity use
-
longer heat pump lifespan
Remember regular service
Even if you clean filters yourself, professional service at regular intervals is still recommended.
At Servion, we normally recommend service every two years for air-to-air heat pumps. This ensures thorough indoor-unit cleaning and a full system check.
By combining regular filter cleaning with professional service, you can keep your heat pump running optimally for many years.
