Is Too Tight a Bad Thing Is Too Tight a Bad Thing?

The federal government is investing billions of dollars in energy efficiency programs that give homeowners the opportunity to retrofit their homes.  Homeowners are being given the financial assistance needed to not just merely improve their homes energy consumption, but also save money on utility expenses.  Who wouldn’t want this?  Use Uncle Sam’s dollars to save energy and my money?  Where do I sign up?

One of the most cost effective solutions to reducing the energy your home is consumes is to seal any air leaks, or rather make your home tight.  But, can you make a home too tight?  The answer is yes and no.

No, a home cannot be too tight provided that the air quality problems that result from reducing air leakage are addressed.  A “tight” house can face potential indoor air quality problems because of moisture buildup, stale air, dust and pollen and chemical pollutants.   Homes that are tight also pose combustion safety concerns due to certain furnaces, water heaters and fireplaces that need adequate fresh air for proper operation, which can be compromised by negative air pressure.

Sounds kind of scary?  Well, this leads to the “yes” part of the answer to our question.  Yes, your home can be too tight when the weatherization process is performed by someone who, is not trained or certified, to address the air quality problems, especially the combustion concerns.

When retrofitting your home to become more energy efficient, which can mean sealing air leaks, replacing old windows, or redoing your insulation, you want to hire a licensed expert who is educated and proficient in building science.
