AC gas filling in Islamabad is one of the most commonly needed services every summer, yet one of the most often done incorrectly. Simply adding refrigerant without checking for leaks or testing pressure is a waste of money. This guide explains current prices, what the service should include, and what to watch out for.
AC gas types used in Pakistan
R-22 is the older refrigerant used in most non-inverter ACs manufactured before 2016. R-410A is used in most modern split ACs. R-32 is the newer, more eco-friendly refrigerant used in the latest DC inverter models from Gree, Haier, Daikin, and Mitsubishi. Using the wrong refrigerant type damages the compressor and voids the warranty.
AC gas filling prices in Islamabad 2026
R-22 gas filling: Rs 3,500 to Rs 5,000. R-410A gas filling: Rs 5,000 to Rs 7,500. R-32 gas filling: Rs 5,500 to Rs 8,000. These prices include leak testing, vacuum, digital scale charging, and performance verification at AF Tech Fix. Prices vary by brand, unit size, and how much refrigerant is needed.
What a proper gas filling service includes
1) Leak detection using electronic detector and soap solution. 2) Finding and fixing the leak point before filling. 3) Vacuum pump evacuation of moisture. 4) Digital scale weighing of refrigerant to manufacturer specification. 5) Pressure testing after fill. 6) Performance check measuring suction/discharge temperatures. Any technician who skips steps 1 to 3 is providing a short-term fix.
Red flags when booking gas filling
Avoid any technician who: quotes a very low flat price without inspection, offers to fill gas "by feel" instead of by weight, does not own a vacuum pump, or cannot tell you which refrigerant your AC uses. These shortcuts result in overcharged or undercharged systems that damage compressors and leak again within weeks.
