Maintenance or a malfunction? Request maintenance
An air conditioner that both cools and heats works all year round. Periodic maintenance keeps it hygienic, efficient and quiet, and extends its lifespan.
- Cleaning keeps the air hygienic
- A clean air conditioner is more efficient and quieter
- Checking refrigerant is part of the process
- Periodic maintenance extends the lifespan
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.
F-gas certified
Work on the refrigerant must F-gas certified be carried out by professionals. Our engineers are trained for this and work according to the standard.
Lifespan: how to make your air conditioner last longer
How long an air conditioner lasts mainly depends on proper installation and maintenance. This helps the most:
- Clean filters: a dirty filter makes the unit work harder
- A leak-tight refrigerant circuit: vacuumed during installation and checked during maintenance
- The correct capacity: an air conditioner that is too small runs continuously at full capacity; read calculating air conditioner capacity
- A good location for indoor and outdoor units; read where to place the indoor unit

Frequently asked questions
How often should an air conditioner be serviced?
One maintenance service per year is common, especially if you use the air conditioner for both cooling and heating. With a maintenance contract, we schedule it automatically.
How do I extend the lifespan of my air conditioner?
Keep the filters clean, have the air conditioner periodically checked by an F-gas certified technician, and ensure the capacity matches the room. A well-installed, leak-tight system works more efficiently and lasts longer.
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.
