Does your air conditioner smell, blow weaker, or has your electricity bill jumped? In 9 out of 10 cases, the cause is not a fault but skipped maintenance. A dirty air conditioner runs at full power for a weaker result. And it breaks down precisely in the heat of a Varna summer.
At Svit Komfortu, we provide air conditioner maintenance and cleaning in Varna and the surrounding area. Below you’ll find what the service includes, what you can do yourself, how much it costs and when it’s time to call a technician.

Why maintenance is a must
An air conditioner draws in room air along with dust, pollen and cooking grease. All of this builds up in the filters and on the heat exchanger. Over the months the layer grows, airflow drops, and the unit compensates by running longer and drawing more power.
Regular maintenance restores your air conditioner to its factory efficiency. Here’s what you gain:
- Up to 25% lower electricity bills. A clean heat exchanger and normal airflow mean shorter run times for the same cooling. To see exactly how much your model uses, check how much electricity an air conditioner uses.
- Cleaner, healthier air. Bacteria, mold and dust mites thrive in the damp environment of the evaporator. For a home with children or allergy sufferers, this is a health issue, not a cosmetic one.
- Longer unit life. A well-maintained air conditioner lasts 12–15 years, while a neglected one lasts around 7–8.
- Warranty kept valid. Most manufacturers require proof of annual maintenance, otherwise they refuse warranty repairs.
- No breakdowns at the peak of the season. Breakdowns don’t happen in spring, but on the hottest days, when service companies are overloaded and repairs cost more.
When to schedule maintenance
The rule is simple: once a year for a home and twice a year for intensive use (an office, a restaurant, or an air conditioner that also heats in winter).
The best time is in spring, before you switch on cooling for the first time, in other words, right now. After winter, the indoor unit has collected dust, and the outdoor unit is often full of leaves and poplar fluff. Pre-season maintenance means a clean start and no surprises in the first heat wave.
What full maintenance includes
Professional maintenance is more than taking out the filters. Here’s what we do on a standard visit in Varna:
| Task | What we do | Why it matters |
|---|---|---|
| Filters | Remove, wash, dry | Restores airflow and efficiency |
| Evaporator (indoor unit) | Deep cleaning with foam and rinsing | Removes bacteria, mold and odors |
| Blower wheel and drain pan | Cleaning off dust and sludge | Stops dripping and operating noise |
| Drainage | Clearing the condensate hose | Prevents leaks down the wall |
| Outdoor unit (condenser) | Washing dust and fluff off the fins | Lowers power consumption and operating temperature |
| Disinfection | Antibacterial treatment | Healthy, odor-free air |
| Refrigerant check | Pressure measurement | Detects leaks early, before the compressor is damaged |
| Mode test | Cooling and heating under load | Confirms everything works as it should |
After maintenance, the air conditioner blows stronger and quieter with no smell, and power consumption returns to normal.
What you can clean yourself
Some of the upkeep is easy to do yourself, and we recommend it between professional visits, every 4–6 weeks during the active season:
- Unplug the air conditioner from the power supply.
- Open the front panel and remove the two mesh filters.
- Wash them with lukewarm water and a mild detergent, without a stiff-bristled brush.
- Let them dry completely in the shade — not in direct sunlight and not with a hair dryer.
- Wipe the visible surfaces of the indoor unit with a damp cloth.
- Put the filters and panel back and switch the unit on.
Bad smells and disinfection
A damp or musty smell when you switch it on is the most common sign that maintenance is due. It’s caused by a biofilm of bacteria and mold on the wet evaporator, which regular filter washing can’t reach.
During disinfection, we deep-clean the evaporator and treat it with an antibacterial agent. You’ll notice the difference right away: the air is odor-free, and for homes with allergy sufferers, noticeably easier to breathe. We recommend disinfection at least once a year, together with the spring maintenance.
When It’s a Job for a Technician (Not Just Maintenance)
Some symptoms show the problem goes beyond cleaning. Call us for a diagnosis if you notice:
- The air conditioner cools poorly even after cleaning the filters → a likely refrigerant leak.
- Ice on the pipes of the outdoor or indoor unit.
- The outdoor unit won’t start or shuts off after just a few minutes.
- Unusual noise, rattling or vibration.
- Water dripping from the indoor unit even though the drain has been cleared.
- An error/code on the display or remote control.
In these cases, you need a diagnosis and possibly air conditioner repair in Varna or a refrigerant recharge. If the air conditioner is old and the repair is expensive, a new unit sometimes pays for itself faster. See air conditioners with installation in Varna or work out the capacity you need with our BTU calculator.

Frequently asked questions
How often should an air conditioner be serviced?
Once a year for home use and twice a year for intensive use (an office, a restaurant, or an air conditioner that also heats). Ideally in spring, before the cooling season.

Maintenance and cleaning of a standard wall-mounted split is 42 €. For cassette units, multi-split systems, refrigerant recharge or repairs, we give you a quote after a short phone consultation.
Why does my air conditioner smell bad when I turn it on?
The damp smell comes from bacteria and mold on the wet evaporator. It is fixed with deep cleaning and antibacterial disinfection, usually part of a full maintenance service.
Can I clean the air conditioner myself?
You can handle the filters and visible surfaces yourself: wash the filters with lukewarm water every 4–6 weeks. The evaporator, blower wheel, outdoor unit and refrigerant are a job for a technician with specialized tools.
Does maintenance lower the electricity bill?
Yes. A clean air conditioner restores airflow and runs for less time to deliver the same cooling, with savings of up to 25% compared with a heavily soiled unit.
