Is a window unit right for me?

Window units can be a great option for people looking to cool down a small space, or those who may not have central air or are renting. As with everything, there are pros and cons! Wondering if a window unit is right for your needs? Check out our blog about window units versus central air to find out the pros and cons of window units.

How to install a window unit

Choose the right window.

First, choose a window that’s suitable for an AC unit. You need a window that’s large enough to accommodate the unit and sturdy enough to support its weight–these units can be very heavy and you want to make sure it will be secure. Also, make sure the window can be opened and closed easily. We also recommend that you choose a window that wouldn’t be considered a vulnerable part of your home.

Measure the window.

Measure the dimensions of your window to ensure that an AC unit will fit. You’ll need to measure the height and width of the window opening and the window sill. Also, measure the distance from the window sill to the floor.

Go shopping for the right size AC unit.

The size of the AC unit you need depends on the size of the room you want to cool. A unit that’s too small won’t cool the room effectively, while a unit that’s too large will waste energy and increase your utility bills. Consult with an HVAC professional to determine the right size unit for your needs.

Read the manufacturer’s instructions.

Before installing your AC unit, be sure to read the manufacturer’s instructions carefully. This will help you avoid common mistakes and ensure that your unit is installed safely and effectively. Reading the box is never fun! However, for something like this, we definitely advise it.

Put together the installation kit.

Most window AC units come with an installation kit that includes brackets, screws, and foam padding. Assemble the kit according to the manufacturer’s instructions.

Install the brackets.

The installation kits will come with brackets that go onto the bottom of the AC unit. Install them and make sure they are securely attached and leveled.

Insert the unit into the window.

This may require more than one person as these can be heavy and windows can be tall. Lift the AC unit onto the window sill and slide it into the window opening. Make sure the unit is centered and level, and the top of the unit should be tilted slightly toward the outside to allow for proper drainage.

Secure the unit.

Once the unit is in place, use the brackets to secure it to the window sill. Make sure the unit is level and secure by giving it a few test bumps.

Seal the gaps.

Use the foam padding that comes with the installation kit to seal any gaps between the unit and the window frame. This padding will prevent warm air from entering your home and keep your AC unit running efficiently–get ready for cool air!

Plug it in and enjoy!

Finally, plug in the unit and turn it on. Adjust the temperature to your desired setting and enjoy the fresh air!

The bottom line

Installing a window AC unit is a great way to cool down your home during the hot summer months. By following these simple steps, you can install your unit safely and effectively, ensuring that your home stays cool and comfortable all season long. If you have any questions or concerns about installing your window AC unit, be sure to consult with an HVAC professional. They can provide you with additional guidance and ensure that your unit is installed safely and correctly.
