Your AC is running but the room is not getting cold? The most common reason is low refrigerant gas. But before we refill anything, we make sure the gas will actually stay — because adding gas without checking for leaks is just wasting your money.
How We Do It — Step by Step
Most technicians just refill the gas and leave. We do it differently.
✅ Step 1 — Full AC Inspection
Before touching the gas, we inspect your entire AC — indoor unit, outdoor unit, pipes and joints.
✅ Step 2 — Leak Test with Soap Foam
We apply soap foam on every pipe joint and connection point. If there is a leak, bubbles will appear — we find it and fix it first. No leak test, no gas refill — that's our rule.
✅ Step 3 — Pressure Check
We use a pressure gauge to check the current gas level and confirm how much needs to be refilled.
✅ Step 4 — Gas Refill
We refill with the correct gas type — R22, R32 or R410A — based on your AC model. The right gas in the right amount makes all the difference.
✅ Step 5 — Final Performance Check
After refilling, we run your AC and check the cooling performance — so we leave only when everything is working perfectly.
Why choose our AC Gas Refil service in Dhanmondi,Dhaka
When a resident on Road 15 in Dhanmondi called us about their AC not cooling, the first thing our technician did was not reach for the gas cylinder. He performed a soap foam leak test on every joint, connection and valve in the refrigerant circuit — methodically working from the indoor unit through the pipe run to the outdoor compressor. He found a pinhole leak at the flare connection near the outdoor unit — a leak so small that the gas had been escaping for months before the cooling loss became noticeable. Only after repairing that connection, re-flaring the joint and pressure testing with nitrogen did we proceed to gas refill. The resident had been quoted a simple gas refill by two previous technicians. Both refills had lasted less than three months. Our repair lasted — because we fixed the cause, not just the symptom. Our Dhanmondi-area workshop, supported by Khan Refrigeration's supply point near Jigatola, ensures we always have the correct refrigerant type — R22, R32 or R410A — available for same-day service across all of Dhanmondi's roads.
