How to Install a Window Air Conditioner in a Crank Window
Although modern air-conditioning systems have replaced most window air conditioners, these units are still available. If you’ve found a home or apartment you love that doesn’t have central air conditioning, cool off by installing a window air-conditioning unit in a crank window with this step-by-step guide.
Step 1 - Open the Window
First, open the window by using its crank handle. Continue to crank the window open until you get to the stopper point.
Step 2 - Take out the Screws
Next, use a screwdriver to take out all the stopper screws. Put them in a safe place so that you can replace them at a later date if need be.
Step 3 - Take out the Operator Control Arm Clip
Use a screwdriver to detach the operator control arm from the bracket. If the crank window in your room comes with a vent-control plate, take this off by removing the screw and sliding the plate control away from the hinge plate.
Step 4 - Take off the Hinge Arm
Next, take the hinge arm off of the window frame by unscrewing the screws. Also, veer the window crank handle away from where you’re working.
Step 5 - Take off the Hinge
Grab the window sash tightly and move the lower and upper hinges away from the window frame. Take off the hinge by unscrewing the screws.
Step 6 - Put in the Mounting Brackets
Put in the mounting brackets that are a part of your air-conditioner kit with socket wrenches. If your house is made with stone or brick, you might need to drill starter holes to complete this step.
Step 7 - Install the Air Conditioner From the Inside
The air conditioner needs to be installed from the inside. You will also need a helper for this step on the outside.
Pick up the air conditioner, and put it in the window. Slowly nudge it outside. As you’re doing this, your outside helper must guide the air conditioner and assist in holding it up. Do not push any more once the inside bottom lip of the unit meets the window sill.
Step 8 - Attach the Air Conditioner
Affix the window unit to the mounting brackets using bolts or screws, with sockets or a screwdriver.
Step 9 - Measure and Cut Plywood
With measuring tape, stretch and measure from the top lip of the inside part of the machine to the window-sill top, and also from the left to the right side of the window. Then, cut your plywood accordingly.
Step 10 - Place Plywood
Put the plywood you just cut into the opening, and seal it at each edge by using clear silicone caulking. Extract the side extensions on the machine, plug the air conditioner in, and switch it on.
Once you’ve followed the preceding ten steps, you will have installed a window air conditioner in a crank window. To increase the life of your unit, weatherize the air conditioner for winter.
