Frequently Asked Questions

What is AC gas refill cost in Hyderabad?

AC gas refill at GarageNation Hyderabad costs ₹1,500–₹3,500 for R134a refrigerant top-up. But if the gas is low, there is always a leak — we do UV dye leak detection (₹800 extra) to find and fix it, otherwise gas needs to be topped up again within 6–12 months.

Why does AC cool but then get warm?

AC that cools initially but warms up usually indicates the compressor is overloading from low refrigerant pressure and the pressure switch is cutting it off. Other causes: a refrigerant overcharge causing high pressure cutout, or a failing compressor clutch slipping once it heats up.
