Got Questions About AC Repair & Appliance Services in Dhaka?

Most standard AC repair jobs in Dhaka are completed within 1 to 3 hours during a single visit. Common issues like gas leaks, faulty capacitors, dirty filters, or thermostat problems typically get sorted in the same appointment.

If the problem requires a specific spare part that’s not immediately available, the repair may take one additional day while we source the part. We always inform the customer upfront before proceeding.

Yes. Mohammadi Engineering Ltd. repairs all major AC brands used in Dhaka homes and offices. This includes:

• General, Gree, Midea, Walton, Samsung, LG, Panasonic
• Daikin, Carrier, Sharp, Haier, Mitsubishi, Chigo, Singer
• All split AC, window AC, cassette AC, and inverter AC models

We handle both residential and commercial units. Our team regularly works on split AC systems and inverter AC units across Dhaka city.

These are the AC issues we deal with most frequently across Dhaka city:

• AC not cooling: Usually low refrigerant gas or a dirty evaporator coil
• AC not turning on: Capacitor failure, PCB fault, or power issues
• Water leaking from AC: Blocked drain pipe or improper installation angle
• AC making strange noise: Fan motor wear, loose parts, or compressor issues
• High electricity bill from AC: Gas shortage, dirty filters, or compressor inefficiency
• AC remote not working: Sensor fault or PCB problem
• AC bad smell: Mold in the drain pan or dirty coils

Whatever the issue, our AC repair team in Dhaka will diagnose it properly before doing any work.

Yes, we do. Mohammadi Engineering Ltd. provides 24/7 emergency AC repair service across Dhaka city — including nights, weekends, and public holidays. We understand that in Dhaka’s heat, a broken AC isn’t something you can wait until morning to fix.

Just call 01859-976686 and describe the problem. We’ll dispatch the nearest available technician as quickly as possible.

In Dhaka’s humid and dusty climate, we recommend professional AC servicing at least twice a year — ideally before summer (March–April) and once after the monsoon season (October–November).

Regular servicing:

• Reduces your electricity bill by 15–25%
• Extends the lifespan of your AC unit
• Prevents sudden breakdowns during peak summer heat
• Maintains better air quality inside your home or office

If your AC runs nearly all day (common in Dhaka), consider servicing it every 4 months.

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

• The AC runs but blows warm or mildly cool air
• You notice ice forming on the copper pipes or indoor unit
• The compressor runs continuously without cooling the room
• Your electricity bill has increased without any change in usage
• You hear a hissing or bubbling sound from the unit

If you’re seeing any of these, it’s time for an AC gas refill in Dhaka. Note that gas doesn’t simply “run out” — a leak is usually the root cause. We’ll check for leaks before refilling.

We use the correct refrigerant type based on your specific AC model and manufacturer recommendation. The most common gas types we work with in Dhaka are:

• R-22 (Freon): Used in older AC models (being phased out globally)
• R-410A: Standard in most modern split AC units
• R-32: Used in newer, more energy-efficient inverter ACs
• R-134A: Common in some compact and window AC models

Using the wrong gas type damages your compressor. Our technicians always verify the correct specification before refilling. We do not mix refrigerant types.

If your AC system has no leaks, refrigerant gas should last the entire lifespan of the unit — often 10 to 15 years. AC systems are sealed, so gas loss is always a sign of a physical leak somewhere in the system.

If you’re getting your AC gas refilled every 1–2 years, there’s definitely a leak that hasn’t been properly fixed. Mohammadi Engineering Ltd. always performs a leak test before and after every gas refill to ensure the problem is resolved, not just temporarily patched.

AC repair costs in Dhaka vary based on the type of problem, parts needed, and the AC model. Here’s a general idea of what to expect:

These are indicative figures. Mohammadi Engineering Ltd. provides a free diagnosis and cost estimate before starting any repair — no surprise bills.

We charge a standard visit and inspection fee when our technician comes to your home or office. This fee is clearly communicated to you before the visit. If you proceed with the repair, this fee is usually adjusted or waived against the total repair cost.

We believe in being fully transparent about charges. There are no hidden fees at Mohammadi Engineering Ltd. — you’ll always know the full cost before any work begins.

Yes. We provide a service warranty on repairs carried out by Mohammadi Engineering Ltd. The warranty period depends on the type of work done:

• Labour warranty: Covers our workmanship on the repair carried out
• Parts warranty: New parts installed come with the manufacturer’s warranty
• Gas refill warranty: If the gas drops again within the warranty period, we investigate at no extra labour charge

Specific warranty terms will be communicated when we complete the job. We stand behind our work — if the same issue recurs within the warranty window, we come back and fix it.

Yes, we provide doorstep refrigerator repair service in Dhaka. Our technician comes to your location with the necessary tools and commonly needed parts. Most standard fridge issues — including cooling problems, compressor noise, ice buildup, and gas leaks — are repaired on-site without needing to transport the appliance.

We work on all popular refrigerator brands used in Dhaka: Samsung, LG, Walton, Singer, General, Haier, Sharp, Hitachi, and more.

Your refrigerator may need a fridge gas refill in Dhaka if you notice:

• The fridge is running but not keeping food cold enough
• Frost buildup is unusual or excessive (or completely absent in frost-free models)
• The motor runs continuously without cycling off
• You can hear the motor straining more than usual
• The freezer section works, but the fridge section is warm

Always have a qualified technician do the gas refill — using the wrong refrigerant or incorrect pressure can permanently damage your compressor.

This really depends on the age of the fridge, the repair cost, and the nature of the problem. A simple rule most technicians follow: if the repair cost is less than 50% of the current replacement value, repair is usually the better choice.

When to consider repair:

• The fridge is less than 8–10 years old
• The issue is a minor part like a thermostat, relay, or door seal
• The compressor is still functional

When buying new might make sense:

• The fridge is over 12 years old and needs a compressor replacement
• Repair costs keep recurring every few months

Our technicians will give you an honest assessment — we won’t push repairs when replacement makes more financial sense for you.
