Regular maintenance prevents emergency breakdowns during Mumbai summers. Homeowners can safely handle filters and exterior cleaning; coil chemicals and gas work belong to certified technicians. A clean filter alone can improve cooling noticeably and cut electricity use, because the compressor no longer fights restricted airflow.
Every two to four weeks in peak season, switch the unit off at the MCB, slide out the filters, rinse them under a tap, and let them dry fully before refitting. Wipe the front louvers and check that the outdoor unit has at least 30 cm of clearance with nothing blocking the fan. Twice a year, book a professional foam-jet deep clean that covers the evaporator and condenser coils, a drain flush, and a gas-pressure check.
