Split AC Installation: Step-by-Step Walkthrough for First-Timers
Buying the AC is only the first step. Getting it installed correctly is just as important especially in Indian homes where room sizes, wall types, and plug point locations vary a lot.
Whether you’re in a Noida flat or a tier-2 city house, installation involves more than unpacking and switching it on. Here’s what actually happens when the technician team arrives, what you’ll need to be ready for, and which parts may cost extra.
Step 1: The AC Technicians Arrive and Inspect the Room
Once AC Installation team reaches your home, the first thing they’ll do is check your room setup:
- They confirm the wall where the indoor unit will be installed
- Check for plug point availability, wall height, and airflow clearance
- Look at where the drain pipe will exit bathroom, outside wall, or balcony
- Decide on the location of the outdoor unit (usually balcony or wall outside)
If anything isn’t ready like no power socket, or poor drainage slope they may suggest additional work or reschedule the visit.
Step 2: Drilling Begins for AC Brackets and Pipe Passage
Once the position is final, installation starts with wall drilling:
- A core drill machine is used to fix the wall bracket for the indoor unit
- A round hole (2-3 inches) is made through the wall for the copper pipe and drain hose
- Expect dust and noise cover nearby furniture or electronics in advance
Technicians use anchors, wall plugs, and bolts to hold the indoor unit’s bracket firmly in place.
Step 3: Mounting the Indoor AC Unit and Laying the Drain Pipe
With the bracket installed, they mount the indoor AC unit and prepare the connections.
- The copper pipe and drain line are passed through the wall hole
- These pipes are wrapped in insulation foam and sealed
- The drain pipe must be installed at a downward slope to let water flow freely
If the drainage route isn’t ideal, they may suggest a drain pump (at extra cost) to avoid dripping inside the room.
Step 4: Placing and Connecting the Outdoor AC Unit
Next, the team installs the outdoor unit, which is heavier and requires stable support.
- If placing on the floor or balcony, they use rubber feet or a metal base
- If wall-mounted, they use a wall bracket, which may cost ₹500-₹1000 extra
- The copper pipe, gas line, and wiring from the indoor unit are connected here
- A vacuum pump is used to remove moisture and air from the gas lines before sealing
This part is crucial for gas efficiency if skipped or rushed, your AC may underperform.
Step 5: AC Power-Up and Cooling Test
Once everything is in place:
- The AC is switched on and tested for cooling, fan speed, and compressor response
- The technician checks for gas leaks, vibration, and noise
- They’ll also confirm that condensed water is draining properly
They may give you a short demo on how to use the remote, set timers, and change between modes (Cool, Dry, Fan, Sleep).
Step 6: Cleanup and Final Paperwork
Not all technicians clean the area after the job, especially if a lot of drilling was done. You may need to:
- Use a broom or vacuum to clean up dust near the wall and floor
- Ask them to clean basic visible areas before leaving
Finally, they’ll provide:
- A signed installation receipt
- Service contact numbers or a follow-up confirmation SMS from the brand
Take a photo of the paperwork for future service requests.
What You Might Be Charged Extra for During Installation
Even if your AC brand promises “free installation,” many important components still cost extra.
| Item/Service | Typical Extra Cost (₹) |
|---|---|
| Extra copper pipe (beyond 3m) | 700-1,200 per metre |
| Outdoor wall stand | 500-1,000 |
| Core wall drilling (thick concrete) | 300-700 |
| Drain pipe or wire extension | 100-200 per metre |
| Bolts, clamps, or insulation tape | 200-500 total |
| Drain pump (optional, if needed) | 1,500-3,000 |
| Gas top-up (only if required) | Rare for new units |
Always ask for a full price sheet before confirming the installation appointment.
Make Split AC Installation Smooth
- Keep the area ready with power socket and clear access
- Make sure you or a family member is present during the visit
- Record the technician’s name and number if not sent by SMS
- Take photos of the final setup for warranty and future support
- Avoid third-party installers unless approved by the brand
Installing your AC well leads to better cooling, lower costs, and a longer lifespan. With this knowledge, you can plan your day without unexpected issues.
