AC not cooling or not heating
Usually a refrigerant leak, a clogged filter or a fault in the outdoor unit. We check the pressure and find the leak.
Diagnostics, repair, maintenance and cleaning for all air conditioner brands, with a 6-month labour warranty. For business clients: 24/7 emergency service.
These are the problems people call us about most often. Most are fixed on the first visit.

A blocked drain or a frozen evaporator. We clean the drain system and check the pipe slope.
Mould and bacteria in the coil and blower. The fix is a deep clean and disinfection.
Worn bearings, loose parts or a dirty fan. We find the source and replace the part.
The error code points to the fault. We read it and test the sensors, control board and wiring.
A power, control board or remote control problem. We diagnose it on site with professional equipment.
Air conditioning or refrigeration down in your shop, office or server room? A technician is on site within 2 hours in Sofia and the surrounding area.
For homes we work during business hours: Mon–Fri 09:00–18:00.
Regular maintenance lowers your electricity bill and extends the life of the unit. We do it before the summer and winter seasons.

We use genuine spare parts from the leading manufacturers.
At least once a year, ideally in spring before the cooling season. If the unit is also used for heating or runs in a restaurant or shop, twice a year.
It depends on the fault. The technician diagnoses the unit first and tells you the price before starting work, so there are no surprises.
Yes. We recharge R32, R410A and other refrigerants, but first we find and fix the leak. Topping up without fixing the leak only buys time.
Yes, most repairs are done at your address. If a large component must be replaced, we book a second visit with the part.
If the unit is over 12–15 years old, runs on the old R22 refrigerant, or the repair costs more than half the price of a new one, replacement is usually the better deal. We will tell you honestly. See AC installation.
Yes. We maintain VRV/VRF systems, chillers and precision cooling, including for retail chains with sites across the country. See our projects and clients.
