Room Still Hot? Your AC May Not Be the Problem

Room still hot at night, even with the AC running?

Before you assume your air conditioner is broken, check what may still be heating your home.

All day, your roof, attic, windows, walls, floors, and furniture absorb heat from the sun. Then, after sunset, that stored heat can keep moving into your room — often right when you are trying to sleep.

In this video, we follow the heat through an ordinary home and uncover why a room can stay hot even when the AC is working.

You’ll learn:
• Why your home can act like a thermal battery
• How a hot roof and attic can keep heating upstairs bedrooms
• Why west-facing windows can keep a room hot after sunset
• How air leaks and hot ducts can make cooling less effective
• When night ventilation helps — and when it can make things worse
• What to check before buying a bigger AC unit or calling for AC repair

The goal is not to make your air conditioner work harder.

It is to stop your home from working against it.

Cooler homes. Lower bills. No nonsense.
