Why maintenance is important
Dirty filters spread dust and cost extra energy. During maintenance we clean the filters and the unit, check the refrigerant and the operation, so your air conditioner continues to run healthily and efficiently.

How often?
A maintenance service once a year is standard, especially if you use the air conditioner intensively for both cooling and heating. With a contract, we schedule it automatically.
STEK-certified
Work on the refrigerant must STEK-certified be carried out by professionals. Our engineers are trained for this and work according to the standard.
Frequently asked questions
Can I clean the filters myself?
You can partially remove and clean the filters yourself. For the annual check of refrigerant and technical components, you should hire a certified engineer.
Why does my air conditioner smell musty?
That often indicates dirty filters or moisture in the unit. A maintenance service solves this and keeps the air fresh.
