When talking to homeowners about having a home energy assessment, we explain each step and how it helps us to understand the energy efficiency of the home. The blower door test is one that is easy to explain but to go beyond the basic explanation to say how it helps to identify air leaks throughout the house is where it gets tough some times.
The video below shows how a gasketed electrical switch can be a serious source of air leakage within the home. If, after watching the video you are wondering how you can cut down on the drafts in your house while simulataneously improving you energy efficiency please contact us about an energy efficency assessment for your home.
