How to Make My Window AC Colder

During those dog days of summer, it is all too easy to ask “how to make my window AC colder.” The best air conditioners, after all, are hampered by several external factors. So what are the various methods to increase the efficiency of your window AC unit? Keep reading to find out.

How to Make a Window Air Conditioner Colder

There are several ways to do this and a lot of this depends on the particular design of your AC, like when you are learning how to make a portable air conditioner quieter. With that said, we have tried to keep these tips as universal as possible.

STEP 1 Close Windows and Doors

The first you should do is close any obvious windows and doors, as this will increase the overall efficiency and efficacy of your window AC. It’s obvious to close windows, but a lot of people forget about the doors leading to their bedroom or whatever room the air conditioning unit is located in. It may seem annoying to keep the door to your bedroom closed when the AC is in use, but it goes a long way to keeping things cooler. Moreover, it’ll prevent your A/C from working so hard, that way you won’t have to reduce the noise of your air conditioner, which can be a challenge.

You’ll also want to get the right amount of BTUs for your window A/C, otherwise, it’ll be working too hard. Additionally, if the A/C is working harder, it’ll create more condensation and it’s a challenge to stop an air conditioner from leaking water, which can cause mold in the walls.

STEP 2 Move it to a Smaller Room

Depending on the power and overall design of your air conditioner, you may need to learn how to move the AC unit. You see, air conditioners are only made to cool off a pre-measured location and some smaller units really struggle to adequately cool down larger rooms. So if you are having trouble with the AC in the living room, for instance, consider moving it to one of the bedrooms.

STEP 3Change or Clean the Air Filters

Always keep up to date with air filter maintenance needs. Replace them or clean them according to the manufacturer’s instructions. Generally speaking, you should switch out or clean your air filters once every one to three months, though this varies depending on use and how dirty your air is.

STEP 4 Insulate the Window

Insulating the window on both the outside and the inside, eliminating any cracks, is a great way to make your AC colder. Start by installing foam side panels and perform surgical work by using spray foam or even caulk. This will help seal gaps around your window air conditioner. Newspapers and cardboard also work but they are less efficient when compared to purpose-built insulators. Insulating the window A/C is also a great way to prevent bugs from coming through into your home.
