Air conditioner and heat pump servicing: how to keep your unit efficient and your indoor air clean
Published
Servicing an air conditioner or heat pump improves heating and cooling performance, reduces odors, and helps keep your indoor air pleasant. Some of it is easy to do yourself (like cleaning the filters), but a thorough clean and inspection is a job for a professional.
Coolflat services air conditioners and heat pumps across Uusimaa: Helsinki, Espoo, Vantaa, and the rest of the region.
Prices starting from:
- 1 indoor unit: €250
- 2 indoor units: €400
How often should it be serviced?
Filters roughly every 2–4 weeks; a professional cleaning service typically every couple of years.
When is it worth booking a service?
When performance drops, the air starts to smell, the unit makes unusual noise, or there's an issue with the condensate water.
What does servicing cost?
At Coolflat, from €250 (1 indoor unit).
How long does servicing take?
Usually about 45–90 minutes per indoor unit.
When is it worth servicing your air conditioner or heat pump?
Book a service if you notice any of the following:
- A stale, "damp," or musty smell
- Reduced performance (heats or cools more slowly)
- Louder-than-normal noise or vibration
- Condensate water not draining properly: dripping or splashing
- Filters getting dirty quickly even when you clean them
If the unit is used heavily (e.g. year-round heating) or installed somewhere that collects dust or grease (e.g. near a kitchen), it usually needs servicing sooner.
What you can safely do yourself
Many aspects of upkeep are simple and worth doing yourself. Do these regularly:
1) Clean the filters
- Turn off the unit.
- Open the front panel and remove the filters.
- Vacuum off the dust and rinse with lukewarm water if needed.
- Let them dry and put them back in.
2) Keep the area around the outdoor unit tidy
- Clear away leaves, twigs, and snow so air can circulate freely.
- Never use a pressure washer on the outdoor unit.
3) Check the condensate water during cooling season
If you're using cooling mode in summer, check that the condensate water is draining normally and not leaking indoors.
4) Do a quick function test when the season changes
When switching from heating to cooling, or back:
- Listen for unusual sounds
- Check that airflow is normal
- Watch for any odors or moisture
Don't do these yourself:
- Don't disassemble the unit beyond cleaning the filters.
- Don't touch the refrigerant or electrical components.
- Don't "flush" the indoor unit with large amounts of water (risk of leaks into the building structure).
When you need a thorough clean, a professional service is the sensible, safest option. The same goes even more for the installation itself:read why installing an AC or heat pump always requires a refrigeration installation license.

Frequently asked questions about air conditioner and heat pump servicing
Can I service the air conditioner or heat pump myself, completely?+
You can do basic upkeep yourself (filters, tidying up around the outdoor unit, checking the condensate drain). A thorough indoor-unit clean and inspection is typically a job for a professional.
Does servicing remove odors?+
Often yes, if the odor comes from dirt and contaminants built up in the indoor unit. If the smell comes back quickly, the cause may be how it's used or ongoing dampness, in which case it's worth looking at the unit and the space as a whole.
How long does servicing take?+
Usually about 45–90 minutes per indoor unit. For homes with multiple units, total time depends on how many there are and the mounting heights.
Does servicing require refrigerant?+
A standard cleaning and inspection service doesn't usually involve adding refrigerant. If a refrigerant leak or performance issue is suspected, that needs a separate diagnosis.
When should servicing be done?+
It's a good idea to book a service when symptoms appear (odors, leaks, etc.), or roughly every 2 years. It's best scheduled for spring or autumn, at the start of the season.
Is servicing worth it even if the unit "works fine"?+
Yes. Servicing helps keep performance strong and prevents problems that build up gradually: odors, reduced airflow, dirt buildup.
Does servicing affect power consumption?+
When airflow and heat exchange work better, the unit can reach its target temperature more efficiently. The real effect depends on the starting condition.
What's the difference between "cleaning" and "servicing"?+
The terms are often used interchangeably. In practice, "servicing" refers to the whole package (cleaning + inspection), or can even include repairs.
Can servicing help if the unit is loud?+
If the noise comes from dirt buildup or restricted airflow, servicing can help. If it's a mechanical fault, a closer diagnosis is needed.
Do you service every brand?+
Our service works for practically all common air conditioners and heat pumps with a wall-mounted indoor unit. For ceiling- or duct-mounted indoor units, please request a separate quote.
