Frequently Asked Questions About AC Service

Answers to common queries regarding air conditioner maintenance, cooling issues, and booking.

In Kochi and coastal Kerala, where high ambient humidity and airborne salinity accelerate dust accumulation and coil corrosion, your air conditioner should receive a professional service every 3 to 4 months. The primary nylon dust filters should also be washed every 2 to 3 weeks during peak summer usage.

An AC that blows room temperature air or cools very slowly is most frequently suffering from choked air filters, dust-packed outdoor condenser coils, low refrigerant gas caused by a micro-leak, or a malfunctioning inverter PCB that fails to ramp up the compressor frequency. Our technicians perform complete diagnostic checks on-site.

Indoor water leakage occurs when the condensate drain pipe is blocked by accumulated dust and algae slime, the drain tray has developed a crack or slope sagging, or when partial ice buildup on the cooling coil melts rapidly and overflows the reservoir. Essentechs technicians clear the drain line with high-pressure suction to eliminate leaks.

Unusual noises typically stem from three areas: a loose or unlubricated indoor blower fan bearing (squeaking), an unbalanced blower drum with dust accumulation (cyclical vibration), or worn outdoor compressor rubber grommets transmitting low-frequency humming through the masonry wall.

You should schedule a professional AC jet clean whenever you notice a decline in air throw, musty mold odors upon turning the AC on, ice accumulating on the copper pipes, or if the unit has operated continuously for more than 4 months without a deep wash.

Yes. Essentechs services all major AC brands available in India, including Hitachi, Carrier, Panasonic, Godrej, Haier, Whirlpool, Lloyd, IFB, Mitsubishi Electric, Mitsubishi Heavy Industries, Toshiba, O General, Hisense, Cruise, Onida, Croma, Midea, Haikawa, Sansui, Akai, and Sharp.
