Tashkent heat doesn't forgive weak cooling: the AC turns on but doesn't cool is one of the most common calls to AlexProService. Sometimes cleaning and a freon top-up are enough; sometimes the compressor or control board needs repair.
Below — typical causes, what you can check yourself, and when to call a technician. We work daily 8:00–22:00, arrival usually within an hour. Diagnostics are free when you proceed with repair. Book: +998 99 411 47 57 or Telegram **@Aleks_Pro_servis**.
Summary
The essentials in a minute
In detail
How to tell it's a cooling problem
The unit "runs" but warm or barely cool air comes from the grille — not normal in Cool mode. Watch for error codes, compressor noise, ice on indoor/outdoor units, or new water leaks.
If the fan spins but room temperature doesn't drop in 20–30 minutes, the issue is likely in the refrigeration circuit, not the remote. Fan-only or dry mode can hide the fault.
Note the brand (Samsung, LG, Midea, Gree, Artel, etc.) and symptoms for the technician — we bring the right tools and common parts.
Dirty filters and evaporator — most common
Dust on filters and the evaporator blocks heat exchange: airflow yes, cold no. In dusty Tashkent summers, filters clog within 1–2 months of heavy use.
Removing and rinsing indoor filters is safe. Deep coil and drain cleaning needs professional equipment — otherwise dirt pushes deeper and cooling gets worse.
Scheduled AC cleaning at AlexProService — from 120,000 UZS: filters, evaporator, drain, antibacterial treatment. We recommend twice a year — before summer and after the season.
Low freon and leaks
Freon doesn't "run out" on its own — low levels almost always mean a leak in the line, joints, or heat exchanger. Signs: weak cooling, iced pipes, compressor runs long with no result.
Topping up without finding the leak is temporary — the problem returns within weeks. Our technician checks pressure, locates the leak, then refills to manufacturer specs.
Refill and diagnostics are part of AC repair — cost depends on freon volume and line access.
Compressor, capacitor, control board
If the compressor won't start or trips on protection — possible start capacitor, relay, outdoor unit overheating, or compressor wear.
The control board may stick in fan mode or misread temperature sensors. On-site testing with gauges and a multimeter saves time — no need to haul the unit to a shop unnecessarily.
Board repair and capacitor replacement are usually cheaper than a new compressor — exact price after inspection, not guessed over the phone.
What to check before the technician arrives
- Remote mode — Cool, setpoint 5–7 °C below room temp.
- Filters — clean and dry after rinsing.
- Outdoor unit — not blocked, fan spinning.
- Breaker — not tripped, no burning smell.
If still no cold — don't run at max 24/7: overheating the compressor makes repair costlier. Call +998 99 411 47 57 or **Telegram**.
