If your home has two or more stories, you could be experiencing the “stack effect” without even knowing it! Simply put, the stack effect is the motion of air that is forced in and out of your home due to changes in pressure. This is caused by the difference in temperature from inside and outside of your home. If your home isn’t properly insulated, rising heat can seep through your attic while pushing down cold air and visa versa. Unfortunately, having cold air pushed downwards while heat escapes isn’t exactly ideal. The stack effect causes the cold air to be pushed down and out through crawl spaces, vents, and windows.
The stack effect affects your home’s heating and cooling efficiency. Your HVAC system will have to work hard to keep the temperature in your home constant as hot air is being pushed up and cool air is being forced out of your home. This results in high energy costs. However, you can combat the stack effect by insulating your home properly. Installing spray foam in areas such as the attic, crawl spaces, basements, and vents can eliminate escaping air.
How do you identify the stack effect? Regardless of what you normally set your thermostat on, if your home always feels too cold in the winter or too hot in the summer, you might be seeing the effects of the stack effect in your home.
