Common AC & Appliance Questions
Answered by Our Experts

This is the most common complaint our technicians handle in Dhaka. The usual reasons are low refrigerant (gas leak), dirty evaporator or condenser coils, a weak or failing compressor, a clogged air filter, or incorrect thermostat settings.

In Dhaka’s humid climate, dust builds up on coils faster than in most cities — so even a relatively new AC can lose cooling efficiency within a few months if not cleaned regularly.

Our AC repair service in Dhaka covers all brands and all fault types. Book a same-day diagnostic visit.

Water dripping inside the room usually means one of the following: the condensate drain line is clogged with dust or algae, the drain pan is cracked or overflowing, or the evaporator coil is frozen and melting. In Dhaka’s summer heat, a blocked drain is extremely common.

Do not ignore this — water damage to walls and ceilings can be expensive. Turn off the AC and call us. Our technicians will flush the drain line and inspect the pan. This is resolved in a single visit in most cases.

No, you should not keep running an AC that has developed an unusual sound. Here is what different sounds typically mean:

• Rattling or vibrating: Loose panels, a foreign object inside the unit, or a loose fan blade.
• Squealing or screeching: Worn fan belt or motor bearing — stop the unit immediately to avoid further damage.
• Clicking or banging: Compressor issue or electrical fault — this needs urgent attention.
• Hissing: Refrigerant leak — a health and safety concern as well as a performance issue.

This depends on the age of the unit and the nature of the fault. As a general guide used by our technicians at Reliable AC Service Ltd.:

• If the repair cost is less than 40–50% of a comparable new unit’s price, repair is usually better value.
• If the compressor has failed and the unit is over 8–10 years old, replacing the unit is often more economical in the long run.
• If the issue is gas loss, dirty coils, a capacitor, or PCB board, repair almost always makes sense regardless of age.

Our technicians will give you an honest assessment with no pressure. We always explain the fault and cost before starting any work. Book a diagnostic visit — the inspection is transparent and straightforward.

Yes. Our technicians at Reliable AC Service Ltd. are trained to work on all major brands sold in Bangladesh, including General, Gree, Midea, Samsung, LG, Haier, Carrier, Daikin, Panasonic, Walton, Marcel, Chigo, and Sharp. We work on both inverter and non-inverter units, split AC, cassette type, window AC, and portable units.

We also carry commonly needed spare parts and refrigerants so most repairs are completed in a single visit.

For Dhaka specifically, we recommend servicing every 3 to 4 months. Dhaka has higher airborne dust and pollution levels than most cities, and the heat and humidity mean ACs run for longer daily hours. This accelerates dust build-up on filters and coils compared to more temperate climates.

If your AC runs 8 or more hours per day — which is common through April to October — monthly filter cleaning and quarterly full servicing is the ideal schedule.

Basic servicing covers filter cleaning, a visual inspection of the indoor and outdoor units, checking gas pressure, and a general performance test. It is the standard quarterly maintenance most households need.

Jet wash / master service uses high-pressure water to deeply clean the evaporator coil, condenser fins, and drain line. This is recommended once a year or when the AC has not been serviced for a long time. It removes deep-seated dust, mould, and bacteria that standard cleaning cannot reach, and it significantly restores cooling performance.

Yes, noticeably. A clogged filter or dirty coil forces the compressor to work harder to achieve the same cooling. This extra load translates directly into higher power consumption. Many customers tell us their bill dropped after a proper servicing — especially after a jet wash on a neglected unit.

Keeping refrigerant at the correct level also matters. Low gas makes the compressor run for longer cycles, increasing power usage. Our team checks gas pressure as part of every full service visit.

Yes. Reliable AC Service Ltd. provides full duct cleaning in Dhaka and HVAC repair and maintenance for residential and commercial properties. Duct cleaning removes accumulated dust, mould, and allergens from your ventilation system — an important step for better indoor air quality, especially in offices and larger homes.

The most reliable signs that your AC is low on refrigerant gas are:

• The AC runs continuously but the room barely cools
• Ice forming on the copper pipes near the indoor unit
• The outdoor unit runs but you feel warm or room-temperature air from the vents
• A hissing or bubbling sound near the indoor unit (indicating an active leak)
• Higher than usual electricity bills despite reduced cooling

Note: refrigerant does not get “used up” like fuel. If your AC needs gas, it means there is a leak somewhere in the system. Simply refilling without fixing the leak is a temporary measure. Our technicians always check for and repair leaks first. See our AC gas refill service page for more details.

Gas refill cost in Dhaka depends on the refrigerant type your AC uses and the size of the unit. The main gas types are R-22 (older units), R-32, and R-410A (common in newer inverter models). Below is a general cost guide — actual pricing is confirmed after our technician checks your unit:

We always give you the exact quote before starting any work — no hidden charges. Call 01824-283141 to book a gas check visit.

Yes. We handle fridge gas refill in Dhaka as part of our refrigerator repair service. Refrigerators typically use R-134a or R-600a. If your fridge is not cooling or the freezer is warm while the motor is running, low refrigerant or a compressor issue may be the cause.

Our technicians will diagnose the problem properly — a fridge that needs frequent gas refills has a leak that should be fixed to avoid repeated costs.
