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.
We recently employed Energy Reduction Specialist of North Carolina to assist us in upgrading and weatherizing a secondary home for energy conservation. This involved many modifications due to the home being 63 years old. The home needed to have a central heating and air unit installed in addition to many other upgrades and modifications. I previously just had a bad experience with another construction co. and had many reservations about starting another construction project. I was pleasantly surprised.
