Why You NEED to Ditch Your Window AC Units

It’s that time of the year again when you have to turn your window AC unit on and hope that it doesn’t take hours to cool down your home.


In actuality, window AC units are the most inefficient way to cool down your home during the summertime.

Here’s why:

Uneven Cooling

Relying on window units to cool your home means your home will be unevenly cooled.

Sure, you can purchase an AC unit with a high BTU number so you can cool all of your home. However, the room the air conditioner is in will be significantly cooler than any other room in the house.

In order to cool rooms that are far away from the main air conditioner, you might have to install smaller air conditioners in them. However, using multiple air conditioners will bring us to the second reason…

High Energy Bills

Window unit ACs aren’t the most energy efficient way to cool your home (compared to central cooling or a ductless mini-split system).

In order to cool an entire home, you would need to run a window AC unit for multiple hours, compared to maybe an hour for a central cooling or mini-split system.

If you wanted to cut down on this cooling time for a window unit, then you would need to add more units. Adding more window units may cut down on how long a single unit runs, but then you’d have to pay for all of the additional ones that are now running.

Talk about a vicious circle…

Short Useful Life

In addition to the runtime and number of units you need to cool your home, you also have to think about the useful life of one. If you’re using your window unit(s) all day and night, summer after summer — then it will reach the end of its useful life a lot sooner than expected.

How many people replace their window units when they’re supposed to?

Not many.

So now you have multiple, inefficient windows units that are all running at the same time for extended periods of time. Yeah, your home is going to be unevenly cooled and your energy bill is going to be way up there…

If you’re sick of sitting in the heat AND overpaying for your monthly energy bills, it’s time to ditch those terrible window units.
