AC Gas Refill Service
in Dhaka — At Your Door
Is your AC running but not cooling? Low refrigerant is the most common cause. Reliable AC Service Ltd. provides professional AC gas refill service across all Dhaka areas — using certified R32, R410A, and R22 refrigerants with pressure-gauge accuracy. No guesswork, no overcharging.
What Is AC Gas Refill — and Why Does Your AC Lose It?
Refrigerant — commonly called “AC gas” — is the chemical that makes cooling possible. It flows through a closed loop inside your air conditioner, absorbing heat from your room and releasing it outside. When the system is sealed and intact, the gas never depletes.
So why does your AC need a refill? Almost always because of a leak — a tiny crack, a loose flare joint, or corrosion in the copper pipes. Dhaka’s humidity and heat accelerate wear on AC systems, especially older units running R22 refrigerant.
Simply topping up gas without finding and fixing the leak is a waste of money. At Reliable AC Service Ltd., our technicians always perform a proper leak detection first, repair the leak if found, evacuate the line, then refill to the manufacturer-specified pressure — backed by a service warranty.

6 Signs Your AC Is Low on Refrigerant Gas
Catching low refrigerant early saves your compressor from permanent damage. Watch for these signs — especially during Dhaka’s hot season.
Warm Air From Vents
Your AC is running but the air coming out feels room temperature or barely cool. This is the most obvious sign of low refrigerant — the system cannot absorb enough heat to cool the air properly.
Ice on Copper Pipes or Coils
Ice forming on the indoor evaporator coil or the outdoor copper pipes signals low gas pressure. The evaporator cannot absorb heat properly and freezes up instead — a sign to stop running the AC immediately.
Hissing or Bubbling Sounds
A hissing noise near the indoor unit or a bubbling sound around the refrigerant pipes often means gas is actively escaping through a small crack or loose fitting. This requires leak repair before a refill.
Electricity Bills Shooting Up
When refrigerant is low, your compressor works overtime trying to reach the set temperature — consuming much more electricity without cooling any better. If your bills jumped without extra usage, check the gas level.
AC Takes Too Long to Cool
If your air conditioner runs for an hour but the room stays warm, low refrigerant is likely. A properly charged AC should reach the set temperature within 15–20 minutes under normal conditions in Dhaka.
Water Dripping from Indoor Unit
Excess water leaking from the indoor unit is often caused by a frozen evaporator coil melting. Low refrigerant causes the coil to ice up, and when the AC shuts off, that ice turns to water and drips inside your room.
Noticing any of these? Don’t delay — call us now before compressor damage sets in.

Using the wrong refrigerant permanently damages your compressor. Our technicians always check your AC’s spec label before refilling — never guessing.
Pro tip: Check the sticker on your outdoor AC unit for the refrigerant type (usually labeled “Refrigerant” or “Gas”). If unsure, our technician will confirm it on arrival.
How We Do the Gas Refill — Step by Step
We follow a strict 6-step process — not just a quick top-up. Every refill includes leak detection, vacuum, and a final pressure verification to ensure you don’t need a second visit.
System Inspection
Technician checks AC performance, reviews AC model and manufacturer spec for correct refrigerant type and required pressure.
Leak Detection
Using electronic detectors and soap solution on all joints, flare fittings, and coil connections. Leak is repaired before refilling.
Vacuum & Purge
System is evacuated using a vacuum pump to remove moisture and non-condensable gases. This step is critical for compressor safety.
Certified Gas Refill
Correct refrigerant (R22/R32/R410A) is charged to the exact manufacturer-specified pressure using a calibrated manifold gauge.
Pressure Verification
We double-check high-side and low-side pressures to confirm the system is operating within the correct range before we leave.
Cooling Test
A 10–15 minute live cooling performance test confirms the AC is producing cold air properly. You see the result before the technician leaves.

What Our Customers Say About Our Gas Refill Service
“My Gree 1.5 ton AC was running but barely cooling. Three technicians before just topped up gas without checking for leaks — it’d go warm again within two months. Reliable AC Service Ltd. found a small leak in the flare joint, fixed it, then refilled. AC has been running perfectly for 4 months now.”
“Called at 9 PM because our office AC stopped cooling mid-summer. The technician arrived within an hour and a half, confirmed it was an R32 gas issue, and had everything fixed by 11 PM. Pricing was clear, no drama. Will call them for all our office ACs.”
“I have an older LG window AC using R22. Most technicians said they don’t carry R22 anymore. Reliable AC Service Ltd. had it. Technician was clean, professional, and explained exactly what he was doing. My old AC is cooling better than it has in years.”

Frequently Asked Questions — AC Gas Refill in Dhaka
The clearest signs are: warm air blowing despite the AC running, ice forming on the copper pipes or coils, a hissing sound near the indoor unit, your electricity bills going up without more usage, and the AC taking much longer than usual to cool the room. If you notice any of these, stop running the AC and call us on 01824-283141 — continuing to run a low-gas AC can damage the compressor.
A properly sealed AC should never need a gas refill throughout its entire lifespan — refrigerant circulates in a closed loop and doesn’t get used up. If your AC needs frequent refills (every year or two), it means there’s a leak somewhere in the system. The right fix is to find and repair the leak, then refill. Simply topping up without fixing the leak is just spending money repeatedly for temporary relief.
AC gas refill prices in Dhaka typically range from ৳2,000 to ৳8,000 depending on the refrigerant type (R22, R32, or R410A), AC tonnage, and whether a leak repair is also required. A simple R32 or R410A top-up usually falls between ৳2,500 and ৳5,000. If a leak needs to be repaired first, add ৳1,500 to ৳3,000 to that. We always confirm the full price before starting any work — no surprises.
No — you should never use a different refrigerant than what your AC was built for. Different gases operate at different pressures, and using the wrong one can permanently damage the compressor, void your warranty, and even pose safety risks. The correct refrigerant type is printed on the specification sticker on your outdoor unit. Our technicians always verify this before touching the system.
A standard gas refill — including leak detection, vacuum, refill, and final cooling test — typically takes 60 to 90 minutes. If a leak repair is needed (brazing, pipe replacement, or flare joint tightening), add another 30 to 60 minutes. We’ll give you a realistic time estimate before starting so you can plan accordingly.
Yes — Reliable AC Service Ltd. still carries R22 (Freon) for older AC units. However, R22 is being phased out globally due to its ozone-depleting properties, so it is becoming harder to source and more expensive. If your AC uses R22 and needs frequent refills, it may be worth discussing whether upgrading to a new R32-based system would be more cost-effective over time. We’re happy to advise honestly.
Yes. If our technician discovers that low refrigerant has caused compressor damage or other issues, we can handle the full repair. Reliable AC Service Ltd. offers comprehensive AC repair service in Dhaka — from compressor replacements to PCB repairs, capacitor faults, and more. We prefer to diagnose everything on the first visit so you can make an informed decision.
