Step-by-Step Process of Installing an Air Conditioner: A Complete Guide

Posted: Apr 01, 2025
The first step is selecting the AC unit that fits your needs. Consider these factors:
-
Room Size: Use a BTU calculator (like this BTU calculator) to determine the right AC capacity.
-
Type of AC: Window AC for small rooms, split AC for medium to large spaces, and central AC for whole-house cooling.
-
Energy Efficiency Rating (EER): Higher ratings mean better efficiency.
At Raza Company, we help customers choose the right AC units based on their space, budget, and energy efficiency goals.
Step 2: Gather the Necessary Tools and MaterialsYou’ll need the following for a smooth installation:
-
AC unit (window, split, or central)
-
Mounting brackets (for window AC)
-
Power drill and screws
-
Tape measure
-
Screwdriver
-
Level
-
Duct tape or weather stripping (for sealing gaps)
-
Safety gloves and goggles
-
Clear the Area: Make sure the window or wall where you’ll install the AC is clean and unobstructed.
-
Check for Electrical Supply: Ensure there’s a dedicated power outlet nearby.
-
Secure the Window (for Window ACs): Remove any obstructions and measure the window to ensure the AC fits properly.
If you’re installing a window AC, follow these steps:
-
Attach the Brackets: Secure the mounting brackets on the window frame to support the AC’s weight.
-
Lift the AC Unit: With assistance (since AC units can be heavy), lift the unit onto the brackets.
-
Level the AC: Use a level to ensure the AC is slightly tilted backward to allow proper drainage of condensate water.
-
Secure the Unit: Screw the unit into the window frame for stability.
-
Seal the Gaps: Use weather stripping or duct tape around the edges to prevent air leaks.
Pro Tip: For added security, you can install a window lock to prevent unauthorized access.
Step 5: Install the Split AC SystemSplit ACs require a bit more work since they consist of an indoor and an outdoor unit.
-
Mount the Indoor Unit:
-
Install a wall bracket at the desired location.
-
Hang the indoor unit securely on the bracket.
-
-
Connect the Refrigerant Pipes:
-
Connect the copper refrigerant pipes from the indoor unit to the outdoor condenser.
-
Ensure there are no leaks.
-
-
Electrical Wiring:
-
Connect the power wires to the indoor unit and the external power supply.
-
It’s recommended to have a licensed electrician handle this part.
-
-
Mount the Outdoor Unit:
-
Place the outdoor condenser on a flat, stable surface (like a concrete slab).
-
Secure it with mounting brackets to prevent vibrations.
-
Once everything is installed:
-
Turn on the AC to check if it’s cooling properly.
-
Listen for any unusual noises or vibrations.
-
Check for air leaks around the installation site.
If everything works as expected, your AC is good to go!
Common AC Installation Mistakes to AvoidTo ensure your AC functions optimally, avoid these mistakes:
-
Incorrect Sizing: An AC that’s too small won’t cool effectively; too large wastes energy.
-
Poor Sealing: Gaps around the unit lead to energy loss.
-
Improper Drainage: AC units need proper drainage to avoid water damage.
-
Overlooking Electrical Safety: Faulty wiring can cause electrical hazards.
