How to Keep Your House Cool in The Summer blog header image
July 20, 2023

As summer has finally started heating up here in Midcoast Maine, many homeowners are struggling to keep cool as the temperatures rise. Many older homes in the area aren’t equipped with permanent cooling systems, making them stuffy and uncomfortable during the warmer months. But did you know that there are certain home performance upgrades that can help keep your home cool? 

At Evergreen Home Performance, we use a building science approach to home upgrades that view each part of your home as a small piece to a larger working system. With our comprehensive services and expertise in energy efficiency, we can help you keep your home comfortable during the summer. 

Insulation & Air Sealing Upgrades

It’s a common misconception that insulation only works in the winter. In fact, insulation keeps the heat out of your home in the summer in the same exact way it keeps the cold out in the winter—by creating a barrier that resists heat flow through your home. Gaps and cracks in your building envelope also make it susceptible to excess heat and humidity, allowing conditioned air to escape your home and creating negative pressure known as the stack effect. 

With insulation upgrades and air sealing from Evergreen Home Performance, your home will stay cooler longer throughout the summer and get other year-round benefits, like:

Why Insulation & Air Sealing Work Best When Combined

While insulation controls the heat flow in and out of your living spaces, air sealing eliminates energy waste from your home. The performance of insulation is optimized when combined with air sealing—and it can even extend the lifespan of your cellulose insulation!
