Thinking of installing a split AC at home and don’t know where to start?

In this blog, I’m going to walk you through the complete process of installing both the indoor and outdoor units of a split wall-mounted air conditioner.

I’ll also talk about installation costs, some accessories you might need, and a few tips on choosing the right AC.

Step 1: Unboxing and What You Get

Let’s go opt for a 2-ton split AC because my room is quite large, it’s around 220 square feet. The outdoor unit box comes with two important components: a pair of copper tubes, each 3 meters long. These are what connect your indoor and outdoor units.

Along with these, you also get a cable and a few other essential items like the remote control, user manual, and even batteries. Make sure to double-check that your box includes the copper pipes, the power cable, and the drain pipe; these are essential for installation.

Step 2: Protecting the Pipes

Before installation, the technicians wrapped the copper tubes and the power cable with protective tape. This adds an extra layer of safety and prevents any potential damage.

Do note that this tape isn’t free; it costs around ৳500 or around $4. But it’s worth it for long-term durability.

Step 3: Mounting the Indoor Unit

Next, the team started working on installing the indoor unit by marking the spot on the wall where the AC would be fixed. It’s important to leave at least 3 to 4 inches of space at the top of the unit for proper air circulation.

As the marking is done, they would drill a hole in the wall. This hole is essential for passing the copper tubes and cables from inside the room to the outdoor unit.

Here’s an important tip: you can go for a regular drill to make this hole, but it might damage your wall. I opted for a method called core cutting instead. It gives a cleaner finish and causes less damage.

This service may cost me around ৳3,000 to ৳3,500, depending on your location. Totally optional, but highly recommended if you want a neat finish.

Step 4: Sealing the Wall

After the hole is drilled, the technicians use white cement to cover up any rough or damaged areas around the hole. It helps to keep the look tidy and sealed.

In my case, since the outdoor unit was to be mounted on the rooftop, they had to cut through a tile roof, which unfortunately cracked a tile underneath. Still, we managed to make it work without too much hassle.

Step 5: Connecting Everything

The technicians then passed the copper pipes and electrical cables through the drilled hole and began connecting the indoor and outdoor units. It’s really important at this point to check all the connections for leaks.

The team used a leak detector to ensure everything was properly sealed before finalizing the setup.

Step 6: Mounting the Outdoor Unit

The outdoor unit was fixed using a mounting bracket, which doesn’t come with the AC. This bracket costs around ৳2,000, approximately.

The outdoor unit was also connected to a water drain pipe, which I ensured was routed to the right place to avoid dirty water puddles around the house. That pipe cost me an additional ৳1,200 or so.

Step 7: The Wiring and Testing

Once everything was connected, they checked the power cable and both copper pipes (one going from indoor to outdoor, and the other the opposite direction). Everything was secured and tested for functionality.

Now, about the sound, Seraphic Associates has an incredibly quiet AC. You can barely hear it running. That’s one of the big reasons I chose this model over others.

Frequently Asked Questions (FAQs)

Do I need a stabilizer for my split AC?

Yes, if you live in an area with frequent voltage fluctuations. It helps protect your AC’s compressor.

Can I install a split AC on a glass wall or partition?

Not directly. You’ll need a strong supporting frame or wall surface behind the glass.

What if the copper piping length is more than 3 meters?

You can extend it, but it may require extra refrigerant and might slightly impact cooling efficiency.

How often should the AC’s drain pipe be cleaned?

At least once every 6 months to avoid blockages and water leakage inside the room.

Why does my AC take longer to cool the room after proper installation?

It could be due to incorrect tonnage, poor insulation, or too many heat sources inside the room. A professional assessment helps.
