Karim had just bought a brand new 1.5 ton inverter AC. He was excited — finally, a proper cooling solution for his bedroom. He called a local technician from the neighborhood to install it. The man came, drilled the wall, connected the pipes quickly and left within an hour. Total cost: ৳800.
Three weeks later, the AC was barely cooling. The technician came back, said the gas had leaked and charged another ৳2,500 for refill. Two months after that — same problem. Same excuse.
The real issue was never the gas. It was the installation. The pipes were not properly insulated. The vacuum process was skipped completely. Gas was charged without pressure testing. Every shortcut taken that first day created problems that lasted months.
When Karim finally called Service Wala, our technician spent two hours doing the installation properly — from start to finish. That was eight months ago. The AC has been running perfectly since.
A good AC installation is not about how fast it gets done. It is about how well it lasts.
Why Proper Installation Matters More Than You Think
Most people focus entirely on which AC to buy. Brand, tonnage, energy rating — they research everything. But the installation gets almost no attention. This is a mistake that costs money later.
Here is what happens when AC installation is done poorly —
Gas leaks within weeks because pipes were not properly connected or vacuumed. The compressor works harder than it should — because the refrigerant level was never accurate. Water drips inside the room — because the drainage pipe was fitted at the wrong angle. Noise from vibration — because the bracket was not mounted level. Higher electricity bills from day one — because the system was never balanced correctly.
A proper installation prevents all of this. It is the foundation your AC runs on for the next 8 to 10 years.
How We Install Your AC — Step by Step
We do not rush. Every installation follows a strict process — because every step matters.
📍 Step 1 — Site Assessment
Before drilling anything, our technician checks the best position for the indoor unit — for maximum airflow, minimum pipe length and proper drainage angle. A good position means better cooling and less electricity consumption.
🔩 Step 2 — Bracket Mounting
The indoor unit bracket is mounted level and secured properly into the wall. A bracket that is not level causes vibration noise and puts stress on the unit over time.
🪛 Step 3 — Pipe Fitting with Insulation
Copper pipes are cut to the exact length needed and connected carefully. Every pipe is properly insulated — without insulation, pipes sweat, create moisture and reduce efficiency. This step is where most cheap installations cut corners.
🌀 Step 4 — Outdoor Unit Placement
The outdoor unit is placed in a position with proper airflow around it. A unit placed in an enclosed space or direct sunlight runs hotter and uses more electricity. We advise the best position before mounting.
💨 Step 5 — Full Vacuum Process
This is the step that separates a proper installation from a cheap one. We use a vacuum pump to remove all air and moisture from inside the copper pipe before charging gas. Moisture inside the pipe damages the compressor over time and causes gas to leak. No vacuum — no quality installation. This is non-negotiable for us.
🌡️ Step 6 — Gas Charge with Pressure Testing
After vacuum, we charge refrigerant gas — R22, R32 or R410A depending on your AC model. We use a pressure gauge to verify the exact level. You can watch the gauge reading yourself — full transparency, no guessing.
💧 Step 7 — Drainage Pipe Fitting
The drainage pipe is fitted at the correct downward angle so water flows out properly. A wrongly fitted drain pipe causes water to drip from the indoor unit — one of the most common complaints after a bad installation.
✅ Step 8 — Performance Test
Once everything is connected, we run the AC and monitor it for 10 to 15 minutes. We check cooling output, drainage flow, any unusual noise and outdoor unit operation. We do not leave until everything is working perfectly.
What About Uninstall and Reinstall?
Moving to a new home? Your AC does not have to stay behind.
Many people assume moving an AC means buying a new one — because they are worried about gas loss or damage during removal. With the right technician, this is not a concern.
Our AC Uninstall and Reinstall service safely removes your AC from the old location — sealing the pipes properly to prevent gas loss — and reinstalls it at the new location with the same careful process. Vacuum, pressure test and performance check — everything done again at the new place.
This saves you the cost of a new AC and ensures the unit runs just as well in its new home.
Why choose our AC Installation service in Mirpur,Dhaka
Mirpur's dense residential character presents specific installation challenges that our technicians encounter and solve regularly. The area's heavily loaded electrical infrastructure means that verifying dedicated AC circuit availability is always our first step before any Mirpur installation — running an AC on a shared residential circuit in Mirpur's voltage-variable environment is a recipe for premature component failure. For outdoor unit placement in Mirpur's typically narrow external spaces, we assess each building's specific configuration and recommend positions that maximize airflow while staying within the building's available space. We have installed ACs across Mirpur 1 through 14, including high-floor installations in a 14-story building in Section 10 where the outdoor unit required roof-edge positioning — a job we completed with full safety harness procedure and coordination with the building management. In Pallabi, we installed for a family in a 6th floor apartment at Apon Tower, routing the pipe through an existing utility chase to keep the external façade clean.
