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.
