In 2007 I started a company called Sierra Building Science (SBS). It was primarily a training organization which at one point had a training center in historic Old Sacramento that could handle up to 30 students. It eventually moved to a warehouse where we also manufactured Duc-Blocs and Flow-Boxes for testing duct leakage and airflow.

In 2012 I experienced some serious health issues (undiagnosed diverticulitis that ruptured and put me in the ICU and caused a blood clot near my liver). Those were tough times. (Ask me about having to give myself a shot in the belly every day.) SBS suffered greatly during that time, but I used the down time to finish and publish a book called “HVAC 1.0 – An Introduction to Residential HVAC Systems” that was, and kind of still is, the only book of its kind: a book for people who need to work around HVAC equipment, but not necessarily work on HVAC equipment.

I ended up selling the company and the rights to the book to a company that hired me on full time. A regular paycheck is very attractive when you have one son in college and another about to go to college. The book was never really promoted very well, although it has been sold through TruTech tools for many years (Thank you, even though I never saw a penny of those sales.). SBS changed hands when I went to work for a second company in 2017. I eventually left the second company in late 2021 to focus full time on Kwik Model. They were not pleased about that and refused to sell me back the rights to SBS or the book. In fact, they made me pay full cover price when I bought 30 copies from them for a college course I teach. I had given up on ever owning it again.

Recently, the company that owned it surprisingly and very unexpectedly shut their doors. I contacted them and was able to buy SBS all back for a very fair price. SBS and my book are now back in my hands and I am very grateful. You will be hearing more from SBS in the future and I will definitely be promoting the book and working on an updated edition. You can buy it through TruTech (for a bit cheaper) or you can buy it here: www.sierrabuildingscience.com Thanks, everyone.
