AC Not Cooling? Top 5 Reasons & How to Fix Them Fast in West Bengal
Why Is Your AC Blowing Warm Air?
During the scorching summer and humid monsoon months in Kolkata and West Bengal, an air conditioner running without cooling is a true household emergency. When the compressor hums or the indoor blower spins, but the room temperature stubbornly remains high, one of several common failures is usually responsible.
1. Clogged and Dust-Choked Air Filters In West Bengal's urban areas with high ambient particulate matter, indoor filters can choke with fine dust within 30 to 45 days of daily operation. When airflow across the indoor evaporator coil is severely restricted: - The coil temperature plummets and forms ice sheets. - Air circulation drops drastically. - The compressor overheats and cycles off prematurely.
**Solution:** Remove and gently wash the plastic mesh filters under running lukewarm water every 2 to 3 weeks.
2. Refrigerant Gas Leakage Refrigerant (Freon/R32/R410A) does not get "consumed" like petrol; an AC only needs a gas recharge if there is a physical pinhole leak in the copper condenser or evaporator coils. Exposure to moisture and industrial air pollutants in Kolkata and Howrah can corrode copper joints over time.
**Symptoms of a Gas Leak:** - Hissing sounds around indoor or outdoor valves. - Ice or frost frosting up the thin liquid copper pipe. - Compressor running continuously without cooling.
**Solution:** Professional nitrogen pressure testing, joint brazing, vacuuming, and precision gas recharging.
3. Dirty Condenser Coils on the Outdoor Unit The outdoor unit dispels all the heat extracted from your bedroom. When the aluminum fins are choked with bird feathers, dust, and grime, heat cannot escape. The compressor thermal overload switch then trips every few minutes to save itself from burning out.
**Solution:** Professional high-pressure jet pump chemical wash by a certified technician.
4. Defective Run Capacitor The run capacitor provides the continuous torque needed by the compressor motor. Voltage fluctuations common during storms can weaken or bulge the capacitor, leaving the outdoor fan spinning while the heavy compressor remains silent.

Frequently Asked Questions
Does an AC consume gas over time naturally?
No, an air conditioner is a sealed closed-loop refrigeration system. Gas only decreases if there is a microscopic leak in the coils, flare nuts, or connecting valves.
How often should an AC undergo deep jet pump cleaning?
In dusty urban environments across West Bengal, a deep foam jet wash is strongly recommended once before peak summer and once halfway through the monsoon season.
