Your AC has to work harder and longer as more heat enters your home. Unfortunately, the harder your AC works, the higher your energy bills and the more wear and tear your system sustains.
One of the most common ways for heat to enter your home is through improperly covered or improperly sealed windows. According to Energy.gov, heat gain and loss via windows accounts for 25-30% of residential heating and cooling energy use.
Here are 4 common window mistakes that cost homeowners extra money:

This may sound obvious, but forgetting to cover windows (and doors with windows) during the heat of the day will likely result in a large heat intake through these windows.
Here’s our suggestion: Cover windows and doors that face East/West during the day and let light through windows that aren’t directly facing the sun. You can uncover windows during times of the day when the sun isn’t as intense, like early in the morning or in the evenings.
Essentially, you want to avoid leaving windows uncovered that intake direct sunlight.
Now that we’ve discussed why you should cover your windows, let’s discuss what you should cover your windows with.
One of the best ways to reduce the heat coming in from your windows is to cover them with medium-colored drapes.

A few other factors that help drapes reduce heat intake are:
Other interior window coverings to consider are:
Depending on your windows and the direction they face, you may want to consider multiple interior window treatments. For example, you could install window film as well as medium-colored drapes to minimize the heat that comes through your windows.

Exterior window coverings are just as important as interior window coverings when it comes to preventing heat from entering your home.
Ways that you can protect your windows include:
The more protected your windows are, the less heat will enter your home through them.
Heat not only enters your home through window panes but through spaces around your windows, like holes and cracks. The best way to combat this is to ensure that all of your windows and doors are properly sealed and weather stripped.
This is a project you can complete on your own, but for maximum energy savings, you may want to have a professional come to your home and seal your windows for you, so you can ensure that heat isn’t leaking into your home through unseen cracks or holes.
If you do decide this is a project you want to take on, you can find a step-by-step guide of how to caulk and weatherstrip your windows on Energy.gov.
