If your AC is running but not cooling the room properly, low refrigerant gas is one of the most common reasons — usually caused by a slow leak rather than normal usage, since gas isn't 'consumed' during regular operation. CoolNest provides AC gas filling and refilling across Hyderabad and Secunderabad, using the correct refrigerant grade for your unit — R32, R22 or R410A.
Refilling without fixing a leak just means the gas runs low again within weeks — so we check for leaks first, every time.
It's printed on the AC's rating label, usually near the outdoor unit; our technician also confirms it on-site before filling.
This almost always points to a leak in the piping or coil, which should be fixed before refilling again, otherwise it's a recurring cost.
Manufacturer warranty typically covers manufacturing defects, not gas loss from wear or accidental damage — check your specific warranty terms.
