How much does AC gas charging cost in Islamabad and Rawalpindi?

Yes. We supply and professionally install energy-efficient inverter AC systems, including bracket mounting, copper piping, drainage and electrical work, with a workmanship guarantee.
How often should an AC be serviced in Pakistan?
In the Islamabad–Rawalpindi climate we recommend servicing your AC at least twice a year — once before the summer season (around March–April) and once mid-season — to maintain cooling efficiency, lower electricity bills and prevent breakdowns.
Why is my AC not cooling properly?
Common causes include low refrigerant (gas leak), a dirty air filter or condenser coil, a faulty capacitor or compressor, a blocked drain, or a malfunctioning thermostat. Our technician runs a full diagnostic to identify the exact cause before quoting any repair.
