Installing a Window Air Conditioner

Use caution as window air conditioners are heavy, so you need to make sure that you lift them properly without putting too much pressure on any part of the body, which may injure you. Consider the size of the window before buying a new air conditioner. The right size air conditioner should fill the window opening as much as possible without using a lot of space fillers. The better the units fits the window opening the more efficient it will be at cooling the room.

• Screwdriver

• Support brackets (usually comes with unit)

• Level

• Wood screws

• Foam weather stripping

• Air-Conditioning

1. First, decide which window you will use for installing the air conditioning. You should choose a window with an electrical outlet nearby, so the air conditioner can be connected easily. Make sure there is no furniture near the window which would block air flow.

2. Check the window sill to ensure that it will be stable enough to support the air conditioning.

3. Install the metal support brackets that come with the air-conditioning at an appropriate location to support the weight of the unit as indicated in the installation instructions. The mounting brackets are attached to the unit and screwed in place below the window frame.  

4. Slide the air conditioning unit on to the support brackets and check with the level to insure that the unit is sitting level. Adjust the brackets as necessary to level the unit.

5. Lower the window to the point where the window contacts the air conditioner. Raise the window again and attach a strip of foam weather stripping where the window contacts the air conditioner. Slide the side extensions to close the gaps between the window frame and the sides of the unit. If necessary, attach the extensions on the side wall using wood screws.

6. Apply additional blocking as necessary between the window frame and the air conditioner to close any openings. This will ensure that no cold air escaping from the sides or the bottom of the unit.
