Perhaps you have a few window air conditioner units for a few rooms of your house, rather than having central air.

That’s fine. In fact, it is much cheaper to operate if you stay in a couple of rooms most of the time.

Make sure they are working properly and efficiently. Most of them today are built to run pretty quietly. So if your unit starts acting up and makes some noise, check on it. It may be time to invest in a new one.

When the weather turns colder, remove them from the window. If you don’t, you will be letting a lot of cold air into your house and absolutely jacking up your heat bill. No matter how good the insulation is around it, always remove the unit when it gets colder. The inner parts of the window A/C unit are going to let in air from outside no matter what you do.
