Blower door testing is a way to check the "leakiness" of a home. By depressurizing (pulling air out of a home) and measuring the rate at which air leaks in through openings in the building envelope, we are able to assess how much energy (and money) is escaping through air leaks. Knowing the total amount of air leakage and where the leaks are located helps us determine the most effective strategy to improve your home.

Before we consider an energy retrofit job complete, we use the blower door as our final step to check our work and measure the improvement achieved by our services.

Testimonials

We had our house completely weatherized and retrofitted by ERS. They were extremely professional, they cleaned up very well, plus they were trustworthy, as we both had to work and left our home in the work crew's hands. Our energy bills went down tremendously, and nearly one year later, our house was warm in the winter, and is cool now in the summer, with far less energy usage than before. Their price was very reasonable considering the quality of work and amount needed to get our house up to snuff!  We highly recommend this company.
