Is your air conditioner not cooling, leaking or showing an error right in the middle of a heat wave? Breakdowns almost never happen in spring — they come on the hottest days, when the unit is running flat out. The good news is that many faults can be fixed on site within an hour.
At Svit Komfortu, we repair and service air conditioners in Varna and the surrounding region, regardless of brand. Below you’ll learn how to recognize the fault, the most common problems, how diagnostics work and when a repair makes more sense than a new unit.

When your air conditioner needs repair
Some symptoms can be solved with regular maintenance, but others clearly point to a technical fault. It’s time for service if you notice any of these:
- Not cooling or cooling poorly even after cleaning the filters — the most common sign of a refrigerant leak.
- The outdoor unit won’t start or shuts off just a few minutes after being switched on.
- Ice on the pipes or on the indoor unit while cooling.
- Water dripping from the indoor unit despite a cleared drain.
- Unusual noise — rattling, whistling or strong vibration from the fan or compressor.
- An error or code on the display or remote, flashing lights.
- A burning smell or the air conditioner trips the breaker — turn it off immediately and don’t use it until it’s inspected.
Most common faults and causes
Over 80% of repair calls in Varna come down to a few typical faults. Here’s what they are and what’s behind them:
| Symptom | Likely cause | Solution |
|---|---|---|
| Weak or no cooling | Refrigerant leak, dirty condenser | Leak detection, brazing, recharge |
| Ice on the pipes | Low refrigerant or clogged filter | System diagnostics and top-up |
| The outdoor unit doesn’t start | Capacitor, relay or control board | Replacement of the faulty component |
| Water leaking into the room | Clogged drain or broken pump | Drain cleaning or replacement |
| Noise and vibration | Worn fan bearing, loose bracket | Lubrication, alignment or replacement |
| Error code on the display | Sensor, communication between units, control board | Reading the code and targeted repair |
| The compressor doesn’t run | Start capacitor or the compressor itself | Capacitor replacement or assessment for a new unit |
The exact cause is confirmed only after on-site diagnostics — the same symptom often has several possible sources.
Leaks and refrigerant recharge
The most common reason an air conditioner stops cooling is refrigerant loss. This isn’t something that gets “topped up” periodically — a properly working system is sealed and doesn’t lose gas. If the level has dropped, there’s a leak somewhere, most often at the flare connections or in the outdoor unit’s pipes.
That’s why a proper repair isn’t just a top-up. First we locate the leak (with pressurized nitrogen or a leak detector), fix it, vacuum the system and only then charge it with the exact amount of refrigerant specified for the model. Recharging without fixing the leak is money down the drain — the gas escapes again within weeks.
How diagnostics work
The goal of diagnostics is to pinpoint the fault before parts are replaced by guesswork. A standard visit in Varna includes:
- Inspection of the indoor and outdoor units and reading the error code, if there is one.
- Measuring refrigerant pressure and current draw.
- Checking the electronics — control board, capacitors, relays and sensors.
- Testing the cooling and heating modes under load.
- A clear repair quote before any work begins.
We work on units from all brands — Daikin, Mitsubishi, Gree, AUX, LG, Toshiba and others. After diagnostics, you get a specific price and we decide together whether the repair is worth it.
What to check yourself before calling a technician
Before booking a visit, a few quick checks can sometimes solve the problem or at least save the technician time:
- Check that the remote is set to cooling mode and the set temperature is below room temperature.
- Replace the remote’s batteries — a weak signal can mimic a fault.
- Wash the filters and check that they aren’t completely clogged.
- Make sure the breaker in the panel isn’t tripped and the outdoor unit has power.
- Check that nothing outside is blocking the outdoor unit’s fan (leaves, fluff, plastic).
Repair or new air conditioner
Not every fault is worth repairing. The general rule: if the repair exceeds about 40% of the price of a comparable new unit, it makes more sense to invest in a new air conditioner, which is also more economical.
Repair is almost always justified for relatively new air conditioners (up to 6–7 years old) and for minor faults — drain, capacitor, sensor, recharge after a fixed leak. On the other hand, a burnt-out compressor in an old unit or a leak in a system using banned R22 refrigerant is rarely worth it. In those cases, calculate the capacity you need with the BTU calculator and see air conditioners in Varna with installation included.
Repair and service prices in Varna
Every repair is individual — the price depends on the fault and the parts. That’s why we give an exact quote after diagnostics, with no hidden conditions. Phone consultation is free:
| Service | Air conditioner type | Price |
|---|---|---|
| On-site diagnostics | Wall-mounted split | after consultation |
| Leak detection and refrigerant recharge | Split system | after diagnostics |
| Capacitor / control board replacement | All types | after diagnostics |
| Drain / pump repair | Wall-mounted split | after diagnostics |
| Multi-split / cassette service | Commercial type | after consultation |
For a quote or an emergency visit, call +359 886 392 424. If the air conditioner works but blows weakly or smells, you probably just need air conditioner maintenance in Varna, not a repair.

Frequently asked questions
How much does air conditioner repair cost in Varna?
The price depends on the fault and the parts needed, so we determine it after on-site diagnostics. Phone consultation is free, and you receive the repair quote before any work begins.
Do you repair all air conditioner brands?
Yes. We work on units from Daikin, Mitsubishi, Gree, AUX, LG, Toshiba and other brands, regardless of where they were purchased.
Why is my air conditioner running but not cooling?
The most common cause is refrigerant loss due to a leak at the connections or pipes. The right solution is to locate and fix the leak, then recharge — simply topping up without fixing the leak isn’t a lasting fix.
How quickly can you come out for a breakdown?
We aim to respond the same or next day within Varna and the surrounding region. For emergencies, call us directly.
Is it worth repairing an old air conditioner?
If the repair exceeds about 40% of the price of a comparable new unit, it’s better value to buy a new, more economical air conditioner. For minor faults and relatively new units, repair is almost always justified.
Do you cover all of Varna?
Yes, we serve Varna and nearby neighborhoods and towns. Book an appointment by phone or via the contact form, and a technician will come at a time that suits you.
