AC Gas Filling and Installation: What Every Mumbai Homeowner Should Know
Two jobs cause the most confusion for AC owners: gas filling and installation. This guide explains both in plain language.
Signs your AC has low gas
- Cooling is weak even after cleaning the filter
- Ice forms on the indoor coil or the copper pipe
- A hissing or bubbling sound
- The outdoor unit runs for a long time but the room stays warm
- Electricity bill rises without more usage
Gas is not “consumed”
The refrigerant circulates in a sealed system. If it is low, there is a leak. A good technician finds the leak, repairs it, then refills to the correct pressure. Only topping up will leave you with the same problem within weeks.
R32, R410A and R22
Newer split ACs mostly use R32 or R410A. Older ACs use R22. The gas type is printed on the outdoor unit label and must match; they cannot be mixed. Read our AC gas filling page for how we work.
AC installation checklist
- Strong wall and a safe outdoor support bracket
- Short pipe run with proper insulation
- Correct drain slope so water flows out
- Dedicated power point and MCB, plus a good earthing
- Vacuum and leak test of the pipes before starting the AC
- Stabilizer if your area has voltage swings
