Steps To Install  A Wall-mounted Air Conditioner

Here’s a comprehensive guide on how to install a wall-mounted air conditioner:


Step #1. Pick the location

There may be pipes and cables attached to the studs between the two drywall layers of your wall, so you’ll need to find the studs when picking a position. You can use a stud finder in this step.

Examine the room and choose the ideal location for the air conditioner. It’s advisable to think about your room’s symmetry and the air distribution. Place the air conditioner at the room’s center for a more orderly appearance. It may also ensure that the cold air is spread evenly around the space.

Of course, you should select a location with access to electricity so that you won’t have toinstall a socket, requiring extra effort. I’d also suggest picking a spot on the wall. It should not be too close to the floor or the ceiling. It will keep dust from accumulating in the filter and moisture from forming on the ceiling.


Step #2. Mark up the walls

Draw a horizontal line using the level that will be the upper edge of the opening on the wall. To finish the rectangle, draw three more lines. The rectangle’s sides should be two inches bigger than the unit. Make sure the lines are straight by using your level.

If you have no prior experience with this task, this step might be pretty tricky for you. To avoid making mistakes, I recommend that you practice cutting and drilling before doing anything to your wall.


Step #3. Make the hole

Cut the wall with a handsaw, tracing the lines you drew. The studs and insulating foam will show up when the drywall is removed. Remove the insulation foam that covers the opening by cutting it out. Please don’t throw it away because you’ll need it in one of the following steps.


Step #4. Make the exterior siding opening

On the exterior siding, draw a rectangle that is the same size as the drywall opening. Still use a level to guarantee straight lines. Drill a hole through the rectangle you just drew in the external siding. Make it big enough because you’ll be cutting the rectangle starting through it.

Cut the wall out. The opening is almost done. Remove the studs that are blocking the opening. The opening must be large enough to accommodate the whole air conditioner unit.


Step #5. Attach the frame to the opening

Using two-by-four lumber, make a rectangular frame. The space between the frame should be the same size as the opening. Attach the frame to the inside wall’s opening. Drive nails through it and the studs to firmly fasten it.

The air conditioner will be securely held in place by the frame. Therefore, it is not recommended to mount the device directly to the wall. There really should be a structure to support the unit to prevent system failure and damages to the appliance.


Step #6. Position the AC unit

The device may now be mounted on the wall. Locate the screw holes on the unit’s lips or edges after it’s in place. Bury screws in each screw hole you through the frame that you installed in the previous step.

Make sure you screw it in tightly because the AC’s support depends on it. Check for gaps on the borders that might be leaks or hot air passages. If there are any, use the insulating foam you set aside to cover them.


Benefits Of A Wall Mounted Air Conditioner Unit

Here are the benefits of an air conditioner unit that is wall mounted:


Benefit #1. Wall-mounted air conditioners are significantly cheaper

The most interesting thing about purchasing this sort of air conditioner is its cost. High-end air conditioners are out of reach for most people’s budgets.

Well, not the case with wall-mounted ones. Wall-mounted air conditioners are ideal for people who wish to save money while maintaining comfort in their homes.


Benefit #2. They come in different styles

This benefit will entice you to get a wall-mounted air conditioner because they come in various sizes, styles, and designs. It also implies that you have a variety of AC options, depending on the size and design of your room.


Benefit #3. They won’t detract from the function of your windows

Your windows will not fulfill their true purpose if they are used to support the air conditioner. If you utilize a wall-mounted air conditioner, you will avoid using windows. Thus, nothing will be blocking the windows, allowing you to see the magnificent vista outside.
