What is a Blower Door Test?
Blower door testing in Rahway, NJ provides a simple measurement of the air changes per hour of a home. All homes leak air and it’s a good thing to keep the air fresh but as new air replaces the old air it needs to be reheated or recooled. Too many air changes will result in increased energy cost and discomfort. We use a Blower Door Test to make sure the amount of air changes per hour are acceptable.
There are several steps involved in conducting a blower door test in Rahway, NJ . First we make sure all exterior doors and windows are closed. We choose one central exterior door to open and size an adjustable frame to that door. Next we install a fan and connect it to a nanometer so we can measure both the outside and inside air pressure differential. Once we are ready to start the test we run the fan to a depressurize the house to negative 50 Pascal which is like simulating 20 mile an hour winds running through the home. When the home is depressurized air begins to enter it more forcefully and we measure the difference in air pressure inside the home versus the outside.
Rahway, NJ is in climate zone 4 according to the IECC, International Energy Conservation Code and as such the recommendation is 3 air changes per hour in this climate zone.
