AC Gas Refill Service
in Dhaka — Fast & Reliable
Is your air conditioner running but not cooling the way it used to? Low refrigerant is the most common reason. R. K. Refrigeration Works Ltd. provides professional AC gas refill service across all areas of Dhaka city — using certified R-22, R-32, and R-410A refrigerants with a full leak check included.
Why Your AC Needs a Refrigerant Refill — and When
Refrigerant — commonly called AC gas — is the chemical that absorbs heat from inside your room and releases it outside. Without the right amount of refrigerant, your AC compressor works harder, uses more electricity, and still fails to cool the room properly.
Unlike engine oil, refrigerant does not get “used up” over time in a healthy system. If your AC needs a gas refill, it almost always means there is a leak somewhere in the refrigerant line. At R. K. Refrigeration Works Ltd., our technicians always check and seal any leak before adding new refrigerant — so your refill actually lasts.
- Pressure test to confirm refrigerant level
- Leak detection with electronic leak detector
- Seal any leaks found in copper line or fittings
- Refill with correct refrigerant type for your AC model
- Post-fill cooling performance check
- Written job record provided after service
6 Signs Your AC Has Low Refrigerant
Do not ignore these symptoms — running an AC with low gas puts extra strain on the compressor and can lead to expensive compressor failure.
Blowing Warm or Lukewarm Air
The most obvious sign. If your AC runs but the room stays warm after 15–20 minutes, low refrigerant is the top suspect.
Ice Forming on the Indoor Unit
Frost or ice buildup on the indoor coil or copper pipe usually means the refrigerant pressure has dropped, causing the coil to freeze.
Excessive Water Dripping
When ice melts off a frozen coil, it drips more than normal. If your AC leaks unusual amounts of water, check the refrigerant level.
Sudden Rise in Electricity Bill
Low gas forces the compressor to run longer to try to cool the room. This continuous operation drives up your monthly power bill.
Hissing or Bubbling Sounds
A refrigerant leak often produces a faint hissing sound near the indoor or outdoor unit — a clear sign to call a technician immediately.
Room Never Reaches Set Temperature
If your thermostat is set to 22°C but the room stays at 28°C no matter how long the AC runs, low refrigerant is likely responsible.
Which Refrigerant Does Your AC Use?
Different AC models require different refrigerant types. Using the wrong gas damages the compressor. Our technicians always verify your AC model before refilling.
