How to Install a Window Air Conditioner in a Vertical Window How to Install a Window Air Conditioner in a Vertical Window
A window air conditioner is an inexpensive way to cool your home if you don't have central air conditioning. It is also a good way to cool an add on room or a garage. You want to make sure that the unit you have has enough BTUs (British Thermal Units) to effectively service the room or to keep it as cool as you want it to be. To determine this, measure the room width by length and multiply to get the square footage. Then use a BTU chart to determine what size you will need to cool that room. Follow the instructions below to install your window air conditioner into a vertical window.
Step 1 - Measure for Size
Besides getting the correct size unit to cool the room, you have to get the right size to fit your window. You need to measure the width of the inside window sill. Also measure the height of the window when it is open. You will need to get your air conditioner to fit in this space. You want to have enough space around the unit to have the side and top panels to fit snugly. You will also need to make sure you have the correct size outlet for the power amperage you need to run the unit.
Step 2 - Install the Cabinet
If your unit comes apart, you will install the housing or cabinet first. This will slide off the actual unit and go into the window first. Usually secured with screws, you will attach it to your window sill. If this unit goes too far outside this window you will need to use braces for the bottom of the housing. These will come with the unit.
Step 3 - Place the Unit
Now that the housing is in place, you can slide the air conditioning unit inside the housing. Around the outside of the air conditioner there should be panels to pull out to shut off the open sides of the window. You will have screws also to attach these to the sid of the window sill. Following your instruction manual for the operation of the unit, Plug it in and turn the settings on to test the unit. If it is working turn it off and we will do the final step.
Step 4 - Weatherstrip the Outside
Going outside the window, take your roll of weatherstripping. Running along the outside of the unit and the window, use the weatherstripping to completely seal the unit off from the weather. Although today's units are more secure, it is best to take this extra step to make sure no air gets in or out for more efficient service. After you finish with this, you can go back inside, turn on the air and relax and enjoy it.
