AC Gas Refill in Dhaka: Cost, Types, Warning Signs & What to Expect
📋 In This Guide
What Is AC Refrigerant Gas and Why Does It Matter?
Refrigerant is the substance that makes your air conditioner actually cool. It circulates continuously between the indoor unit (evaporator coil) and the outdoor unit (condenser coil), absorbing heat from your room and releasing it outside. Without enough refrigerant, this heat transfer process becomes inefficient — and your room stays warm no matter how long the AC runs.
Unlike petrol in a car, refrigerant doesn’t get “used up” during normal operation. A well-sealed system should theoretically never need a refill. But in practice, tiny leaks develop over years of use, especially at connection joints and around the copper piping. Dhaka’s heat, humidity, and vibration from urban traffic all accelerate this wear.
6 Signs Your AC Gas Level Is Low
Air Feels Cool, Not Cold
The air coming from the indoor unit is slightly cool rather than properly cold. The AC is working but the temperature difference is too small.
Room Never Reaches Set Temp
The AC runs for hours but the room stays 3–5°C warmer than what you’ve set. The compressor is running constantly without results.
Excessive Water Dripping
More water than usual drips from the indoor unit. Low gas causes coils to freeze and then melt rapidly, creating excess condensation.
Ice on the Copper Pipes
Frost or ice forming on the copper pipes running from the indoor unit is a classic low-refrigerant symptom. Turn off the AC and call immediately.
Electricity Bill Going Up
When refrigerant is low, the compressor runs longer to try and cool the room, consuming significantly more electricity without better results.
Gradual Decline in Performance
The AC that cooled well 2 years ago now struggles. This gradual degradation over months or years points to slowly depleting refrigerant.
R-22 vs R-410A: Which Gas Does Your AC Use?
There are two main types of refrigerant used in residential air conditioners in Bangladesh. Knowing which one your AC uses affects both cost and long-term considerations:
R-22 (Older ACs)
- Used in ACs manufactured before ~2010
- Being phased out globally (ozone-depleting)
- Still available in Bangladesh but harder to source
- Higher cost due to limited supply
- Consider upgrading if AC is R-22 and over 10 years old
R-410A (Modern ACs)
- Used in most ACs made after 2010
- Environmentally friendlier (no ozone impact)
- Widely available in Dhaka
- More efficient cooling performance
- Standard choice for new installations
You can find the refrigerant type on the label on your outdoor unit. It will say “R-22” or “R-410A” (sometimes written as R410A). If you’re unsure, our technicians at Jeet Refrigeration And AC Service Center Ltd. will identify it on arrival.
Never mix refrigerant types. Adding R-410A to a system designed for R-22 (or vice versa) will damage the compressor and other components. Always confirm the gas type before any refill.
AC Gas Refill Cost in Dhaka (2025)
Gas refill pricing in Dhaka varies depending on the refrigerant type, AC capacity (ton), and whether a leak needs to be sealed first. Here’s an honest breakdown of what you should expect to pay:
| AC Type & Gas | Approximate Cost (BDT) | Notes |
|---|---|---|
| 1-ton, R-410A | 2,500 – 3,500 | Most common in Dhaka apartments |
| 1.5-ton, R-410A | 3,000 – 4,500 | Standard for medium-sized rooms |
| 2-ton, R-410A | 4,000 – 6,000 | Larger living rooms, offices |
| R-22 (any size) | 3,500 – 7,000+ | Higher due to limited supply |
| Leak repair + gas refill | Additional 800–2,500 | Depends on leak location and severity |
One important note: any service that quotes a flat BDT 500–800 for a “gas refill” is almost certainly not doing a proper job — proper refrigerant handling requires a pressure gauge, the correct gas quantity, and at minimum 30–45 minutes of work. Cheap refills without leak detection will only need repeating in a few months.
What Actually Happens During a Professional AC Gas Refill?
System Inspection & Leak Check
Before adding any gas, the technician checks the system pressure with a manifold gauge set and looks for signs of leaks — particularly at flare connections, valves, and along the copper piping. Adding gas to a leaking system is money wasted.
Leak Repair (If Required)
If a leak is found, it’s sealed before the refill. This might involve tightening flare fittings, applying leak sealant, or replacing damaged sections of copper pipe.
Refrigerant Recovery (If Needed)
If the system has the wrong gas or mixed refrigerants from a previous bad service, the old gas is properly recovered before the correct refrigerant is added.
Gas Charging to Correct Pressure
The correct refrigerant is added while monitoring system pressure to match the manufacturer’s specification. Overcharging is just as bad as undercharging — both reduce efficiency and can damage the compressor.
Performance Verification
The technician runs the AC and checks the temperature differential between the air going into the return and coming out of the supply — ideally a 10–12°C difference in Dhaka’s climate indicates a properly charged system.
Gas Refill vs. Leak Repair: Understanding the Difference
This is where many homeowners get confused — and where dishonest technicians can take advantage. Here’s the key difference:
A simple top-up just adds refrigerant to bring the pressure back to normal. It’s appropriate only when gas has gradually dropped over many years with no active leak present.
A leak repair + refill is required when there’s an active leak. Without sealing the leak first, the new gas will escape within weeks or months — and you’ll be paying again. Our team at Jeet Refrigeration And AC Service Center Ltd. always checks for leaks before any refill. We serve across all of Dhaka city including Gulshan, Banani, Mohammadpur, Uttara, and beyond.
If you’re also experiencing issues with your refrigerator, note that it uses a similar refrigerant system — our fridge gas refill service in Dhaka follows the same careful process.
