For many of us, a thousand little pin pricks may add up to a hole in your house the size of a window left open 24 hours a day, 365 says per year.

By using a blower door in coordination with air sealing, we can identify the biggest leaks and get them sealed.

Home Energy Medics did a wonderful job on our house. We now have much better heating and cooling. The original audit was very revealing of heat leakage points throughout the house. I had no idea that recessed lighting "cans" could leak so much outside air into the house.
