3 Myths About Indoor Air Quality (IAQ)

Misconceptions About Air Quality and Home Performance

Recently I wrote a blog about the October 2017 firestorms in Northern California. I live and work in the city of Sonoma and was directly affected by the fires. My family and I evacuated our home and waited out the fires on safer grounds until the danger passed. We are OK, life has resumed, but the impact on the region will last for several years.

In my last post, I wrote about how air quality was impacted in the area, and how people responded by using N95 face masks…

It’s Time to Stop Using Fire in Our Homes

At some point in time man gained control over fire. Fire was very useful: it could be used to cook food, provide light, and its heat allowed us to survive in hostile environments.

In fact, the Energy Upgrade California incentive program was originally created as a workforce development solution. Flashback to 2008, the Great Recession: contractors were out of work and the economy was in a downward spiral. The incoming Obama administration designed a program to stimulate the economy.
