Why Do a Blower Door Test on a Home?

Series Summary

One of the important advancements in construction technology is air conditioning. Air conditioners have saved the lives of thousands of people that would otherwise be suffering from heat stroke in the hot summer months. Part of developing air conditioning technology is to install good duct work in your home and make sure your home is pressurized well and not leaking air conditioning. A house that is not properly pressurized will cost you more money in electricity and wear your ducting and air conditioner down quicker.

In this free video series, watch as construction science expert Joshua Lindsey teaches how to give a blower door test. Learn how to control, set up and read a manometer, how to interpret test results, and the benefit of having a good pressurized home with proper ducting. Start saving money on your electricity bill and taking care of your appliances today with these easy step by step videos.

In other words, if I am putting air to the inside and I am pressurizing the home, how much of that air is leaking to the outside. I am spending money to cool the house or heat the house whichever the case may be and I don't want to be putting that air that I spent money to heat or cool into the outside, so we are going to do an air tightness test. By the end of the test we are going to show how much in square inches how much this house is leaking to the outside. "
