AC Gas Refill in Dhaka — Fast, Safe & Affordable
Is your AC running but not cooling properly? Low refrigerant is one of the most common reasons. Bismillah Refrigerator and Electric Ltd. provides professional AC gas refill in Dhaka with certified technicians, genuine refrigerant (R22, R32, R410A), and same-day doorstep service across all Dhaka areas.
What Is AC Gas Refill and Why Does Your AC Need It?
An air conditioner does not consume refrigerant the way a car burns fuel. Under normal conditions, the refrigerant (also called AC gas) circulates in a closed loop and never runs out. If your AC is low on gas, it almost always means there is a leak somewhere in the system.
Simply topping up the gas without fixing the leak is a temporary fix — the gas will escape again within weeks or months. That is why our process always starts with a thorough leak detection and AC repair check before we refill the refrigerant.
We use genuine R22, R32, and R410A refrigerants — the right type for your specific AC model — and fill to the exact manufacturer-specified pressure using digital gauges. This ensures maximum cooling efficiency and protects your AC compressor from premature damage.
8 Signs Your AC Needs a Gas Refill Right Now
Do not wait until your AC stops working entirely. These early warning signs tell you the refrigerant level is dropping — act before it damages the compressor.
AC Running but Not Cooling
Your AC turns on and blows air, but the room stays warm. This is the most common sign of low refrigerant — the system cannot absorb enough heat to cool the air.
Ice on the Evaporator Coil
Frost or ice forming on the indoor unit’s coil means the refrigerant pressure is too low, causing the coil to drop below freezing and ice over — blocking airflow completely.
Electricity Bills Suddenly Higher
When refrigerant is low, your AC works harder and longer to reach the set temperature. The compressor runs more, drawing extra power and raising your monthly bill noticeably.
Hissing or Bubbling Sounds
A hissing noise usually points to a refrigerant leak from a joint or valve. Bubbling sounds often indicate air has entered the refrigerant line — both need immediate professional attention.
AC Takes Too Long to Cool
If your 1-ton or 1.5-ton AC used to cool the room in 10–15 minutes but now takes 30–40 minutes or more, low gas pressure is often the reason behind the sluggish cooling.
Water Dripping Inside the Room
Ice forming on coils eventually melts and drips inside — sometimes on walls or furniture. This dripping is not a drainage issue; it is a sign of low refrigerant causing coil freeze-up.
Warm Air from the Vents
If the air coming from the vents feels room temperature or even slightly warm, the refrigerant level is critically low and the system is no longer transferring heat from inside to outside.
Compressor Getting Too Hot
The outdoor compressor unit feels excessively hot to touch. Running the compressor with insufficient refrigerant causes overheating and leads to compressor burnout — an expensive repair.
How We Perform AC Gas Refill — Step by Step
We follow a proper 6-step process — not just a quick top-up. Every step protects your AC and ensures the refill lasts as long as possible.
Initial Diagnosis
Technician inspects your AC, checks cooling performance, and listens for unusual sounds before touching anything.
Leak Detection
We check all joints, valves, and copper pipes for refrigerant leaks using pressure testing — a step most cheap services skip entirely.
Identify Refrigerant Type
We check your outdoor unit’s nameplate to confirm the correct refrigerant — R22, R32, or R410A — so the right gas is used.
Repair Any Leaks First
If a leak is found, we fix it before refilling. Skipping this step means the gas will escape again within weeks, wasting your money.
Precise Gas Refill
We connect digital pressure gauges and fill the refrigerant to the exact manufacturer-specified pressure — not guesswork.
Performance Testing
After refilling, we run the AC and verify cooling temperature, pressure levels, and compressor operation before we leave.
Which AC Gas Does Your AC Use? R22, R32 or R410A?
Using the wrong refrigerant type can damage your AC. Here is a quick guide — your outdoor unit’s nameplate will confirm the exact type your system requires.
R22 (Freon)
Legacy / Older ACs- Used in ACs manufactured before 2012
- Being phased out globally due to ozone impact
- Still available but at a higher cost
- Common in older Gree, Haier, General units
- We stock genuine R22 for existing systems
R410A (Puron)
Most Common (2012–2022)- Standard in most split ACs from 2012 to 2022
- No ozone depletion, zero ODP rating
- Higher efficiency than R22
- Used in Samsung, LG, Carrier, Daikin and most brands
- Cannot be used in R22 systems
R32
Modern / New Inverter ACs- Used in newer inverter AC models (2020 onward)
- Lower global warming potential than R410A
- More efficient — requires smaller charge quantity
- Common in Midea, Daikin, and newer Gree models
- Slightly flammable — professional handling required

Since 2018, we have been Dhaka’s go-to home appliance repair service. Here is what makes us different from a random roadside AC mechanic.
Trained, Experienced Technicians
Our team handles all major AC brands and refrigerant types — they know the difference between a bad sensor and low gas, saving you from unnecessary charges.
Leak Fix Before Gas Refill
We always detect and repair leaks first. This is the honest way — it prevents repeat gas loss and saves you money in the long run instead of a monthly top-up trap.
Genuine Refrigerant Only
We stock and use only genuine R22, R32, and R410A from trusted suppliers. Counterfeit or mixed refrigerant is a common scam that ruins compressors — we never cut that corner.
Digital Gauges for Precise Pressure
We use digital manifold gauges to fill to the exact manufacturer pressure spec — not by guesswork or feeling the pipe temperature like untrained technicians often do.
Transparent Pricing, No Surprises
We confirm the price before starting work. No hidden charges, no upselling of parts you do not need. What we quote is what you pay.
Open Every Day 8AM to 12AM
AC emergencies do not follow a 9-to-5 schedule. We are available every single day — including weekends and holidays — from 8 in the morning until midnight.

5 Tips to Reduce How Often Your AC Needs Gas Refill
Your AC should never need frequent refills if the system is properly maintained and leak-free. These tips will extend the life of your refrigerant and your AC.
Schedule Annual AC Servicing
A yearly professional AC service includes pressure checks that catch slow refrigerant leaks before they become expensive problems. Do it before summer every year.
Clean Your AC Filters Every Month
Blocked filters force the system to work harder, causing more wear on seals and joints — which eventually leads to leaks. Regular AC cleaning prevents this buildup.
Fix Leaks Immediately — Never Delay
If you notice ice on the coil, hissing sounds, or reduced cooling, call for inspection right away. A small leak sealed early costs a fraction of what it costs after the compressor overheats and burns out.
Protect Outdoor Unit Copper Pipes
Exposed copper refrigerant pipes are vulnerable to physical damage and corrosion. Ensure they are properly insulated and protected, especially if the outdoor unit is in a high-traffic area.
Avoid Running AC with Low Gas
If you suspect low refrigerant, turn off the AC and call us immediately. Running the compressor without adequate gas for even a few hours can cause internal damage that no gas refill can fix.
AC Gas Refill for All Brands — We Service Them All
Whether you own a budget window AC or a premium inverter split, our technicians have the experience and refrigerant to handle your specific model correctly.
