After removing an air conditioner from a wall, there is usually a large hole that needs to be covered immediately. Although it may seem daunting, it is actually only moderately difficult to cover up. You don’t need many tools or materials to do it, and you don’t have to be an expert in carpentry or drywall. Someone with basic handyman skills and the necessary tools and materials can usually complete the project in one day.
Remove the Air Conditioner
Step 1
Remove the trim around the front of the air conditioner and cut off the caulking that holds it to the wall.
Step 2
Take off the front-facing panel and pull out the motor assembly.
Step 3
Use a pry bar to remove the metal jacket that the air conditioner slides into.
Cover the Inside Hole
Step 1
Create a frame around the hole with 2-by-4 foot boards cut to fit the dimensions of the hole. Recess the 2-by-4 foot frame 1/2-inch into the opening.
Step 2
Cut a 1/2-inch thick sheet of drywall to fit the dimensions of the opening and attach it to the 2-by-4 foot frame with drywall screws.
Step 3
Fill the openings around the drywall cover with joint compound and push drywall tape into the joint compound.
Step 4
Add another layer of joint compound to the seams and smooth them with a joint compound knife.
Step 5
Fill the screw depressions with compound and smooth them out with the joint compound knife.
Step 6
Let the compound dry and then sand it smooth with 220-grit sandpaper.
Step 7
Paint or wallpaper the wall or apply whatever treatment you prefer.
Cover the Outside Hole
Step 1
Insert a fiberglass insulation piece with an R-factor of 13 into the opening from the outside. Make sure the paper side of the insulation faces the inside of the house.
Step 2
Cut a piece of plywood to fit the opening on the outside wall. Secure the plywood to the frame with drywall screws.
Step 3
Cover the plywood with shingles, siding, or any other treatment that matches your house.
FAQ
1. What is a wall AC and how does it work?
A wall AC, also known as a through-the-wall air conditioner, is a cooling system designed to be installed directly into a wall. It works by pulling in warm air from the room, cooling it down using a refrigerant, and then releasing the cool air back into the room. The warm air is expelled outside through the back of the unit.
2. What are the benefits of using a wall AC?
Using a wall AC has several benefits. Firstly, it provides efficient cooling for a specific area or room. It is also a space-saving option as it does not take up valuable floor space like a portable AC. Additionally, wall ACs are often quieter than window ACs as the compressor noise is located outside the room.
3. How do I choose the right size of wall AC for my room?
Choosing the right size of wall AC is crucial for optimal cooling. To determine the appropriate size, you need to consider the square footage of the room, the ceiling height, the number of windows, and the level of insulation. It is recommended to consult the manufacturer’s guidelines or seek professional advice to ensure the correct sizing.
4. Can I install a wall AC myself, or do I need professional help?
While it is possible to install a wall AC yourself, it is recommended to seek professional help, especially if you have little to no experience with electrical work. Professional installation ensures that the unit is properly mounted, sealed, and wired, reducing the risk of any potential hazards.
5. How can I maintain my wall AC for optimal performance?
To maintain optimal performance, regular maintenance of your wall AC is essential. This includes cleaning or replacing the air filters, checking and cleaning the condenser coils, and ensuring the unit is free from any obstructions. It is also advisable to schedule annual professional maintenance to identify and address any potential issues.
6. Can a wall AC be used for both cooling and heating?
No, wall ACs are specifically designed for cooling purposes only. If you require both cooling and heating, you should consider installing a separate heating system or opting for a dual-function HVAC system that provides both cooling and heating capabilities.
7. Are there any energy-saving features available in wall ACs?
Yes, many wall AC models come with energy-saving features to help reduce energy consumption. Some common energy-saving features include programmable timers, sleep mode, and energy efficiency ratings. It is recommended to look for units with a high energy efficiency rating (EER) to ensure maximum energy savings.
