-
✓
Correct Capacity Assessment Before Installation We calculate the right AC tonnage for your room size, ceiling height, and heat load — preventing under-cooling and wasted electricity bills.
-
✓
Copper Pipe Only — No Shortcuts We use only genuine copper piping for all refrigerant lines. Cheap aluminum or plastic pipe causes gas leaks within months.
-
✓
Proper Electrical Wiring & MCB Protection Your AC gets a dedicated circuit with correctly rated MCB. Incorrect wiring is the #1 cause of AC compressor failure in Dhaka homes.
-
✓
Vacuum Pump Used Before Gas Charging We always vacuum the refrigerant lines before charging. Skipping this step introduces moisture that destroys your compressor over time.
-
✓
Clean, Neat Finish — No Exposed Wires or Pipes Pipes are channeled neatly along walls or concealed in trunking. We leave your home exactly as we found it — just cooler.
-
✓
Post-Installation Testing & Walkthrough Every installation ends with a full function test — cooling check, remote pairing, drainage test, and a walkthrough of your new AC’s features.
How Our AC Installation Works — Step by Step
A professional installation follows a precise sequence. Here’s exactly what happens when our team arrives at your door.
Site Survey & Planning
We assess the room, identify the best indoor unit position, outdoor unit placement, pipe route, and electrical requirements before any work begins.
Wall Drilling & Pipe Routing
Precise holes are drilled for copper pipe and electrical cable. Pipes are run neatly — exposed routes are covered with matching trunking.
Indoor Unit Mounting
The indoor unit bracket is leveled and anchored securely into the wall. Incorrect leveling causes condensate drainage problems within weeks.
Outdoor Unit Setup
The outdoor compressor is mounted on a vibration-dampening bracket with adequate clearance for airflow on all sides.
Vacuum & Gas Charging
The refrigerant lines are vacuumed to remove moisture, then charged with the correct refrigerant type and quantity specified by the manufacturer.
Testing & Handover
Full operational test: cooling performance, drainage, remote function, and electrical readings verified. You get a complete installation report.
Which AC Capacity Do You Need? — Dhaka Climate Guide
Choosing the wrong tonnage is one of the most expensive AC mistakes. Use this guide for Dhaka’s hot, humid climate. Always round up if your room gets direct afternoon sun.
| Room Size (sq ft) | Recommended Capacity | BTU Rating | Best For | Note |
|---|---|---|---|---|
| Up to 120 sq ft | 1 Ton | 12,000 BTU/hr | Small bedroom, office cabin | Budget Pick |
| 121 – 180 sq ft | 1.5 Ton | 18,000 BTU/hr | Master bedroom, medium lounge | Most Popular |
| 181 – 240 sq ft | 2 Ton | 24,000 BTU/hr | Large drawing room, small office | Recommended |
| 241 – 320 sq ft | 2.5 Ton | 30,000 BTU/hr | Large open plan, conference room | — |
| 321 sq ft and above | 3 Ton+ | 36,000 BTU/hr+ | Hall rooms, restaurants, showrooms | Cassette / Duct unit advised |
Dhaka Tip: Top-floor rooms or rooms with west-facing windows should go 0.5 ton higher to compensate for roof heat gain and afternoon sun. Unsure? Call us on 01949074658 — we’ll recommend the right size for free.

Everything You Need to Know Before Installing an AC in Dhaka
What Does a Professional AC Installation Include?
A complete AC installation in Dhaka is not just about mounting the unit on the wall. The job includes site assessment, wall drilling, copper pipe laying, electrical connection with a dedicated circuit, outdoor bracket mounting, vacuum pumping, refrigerant charging, drainage pipe setup, and final testing. If any of these steps are skipped or done poorly, your AC will either fail early or never reach the manufacturer’s rated cooling efficiency.
Inverter AC vs Non-Inverter AC — Which Should You Install?
For most Dhaka homes and offices running an AC 6–10 hours a day, an inverter AC pays for its higher upfront cost within 12–18 months through electricity savings. Inverter technology adjusts compressor speed based on demand — this keeps your monthly bill between BDT 1,500 and 2,500 compared to BDT 3,500–5,000 for a non-inverter unit running the same hours. We install both types and can advise you based on your usage pattern.
How Long Does AC Installation Take?
A standard split AC installation for a single room takes between 2 and 3 hours when the site is prepared. Multi-zone or cassette installations may take a full day. Our team arrives with all necessary tools and materials — you don’t need to arrange anything in advance.
Do You Need a Dedicated Electrical Circuit for Your AC?
Yes, every AC unit should have its own dedicated electrical circuit with a correctly sized MCB (miniature circuit breaker). Running an AC on a shared circuit with other heavy appliances is a common cause of tripped breakers, voltage fluctuations, and compressor damage. Our team handles this wiring correctly during installation at no extra charge for standard setups.
What Is Vacuum Pumping and Why Does It Matter?
Before refrigerant gas is added to your AC, the pipe circuit must be evacuated of all air and moisture using a vacuum pump. This is a critical step that many cheap installers skip to save time. Moisture left in the lines reacts with refrigerant to form acid that corrodes the compressor from inside. At Bismillah Refrigerator and Electric Ltd., vacuum pumping is standard on every installation — without exception.
Can You Install an AC in an Apartment with Limited Wall Space?
Yes. We work in apartments throughout Dhaka daily and are experienced with tight spaces, shared walls, and building management restrictions. Our team will advise on the best position for both indoor and outdoor units before any drilling begins. For apartments where outdoor unit placement on the building exterior is restricted, we offer cassette and duct-type alternatives.

What Dhaka Residents Say About Our AC Installation
Real feedback from real customers across Dhaka who trusted Bismillah Refrigerator and Electric Ltd. with their AC installation.

“We needed a cassette AC installed in our office in Banani. The technicians had the right equipment, handled the false ceiling access carefully, and completed the entire installation in one day. Cooling is excellent. Will use again for our second office.”
“I moved to a new flat in Dhanmondi and needed my old General AC reinstalled. The team dismantled everything carefully, moved the unit, and reinstalled it properly including a gas top-up. Much cheaper than what other services quoted me.”
