Every home is unique and differs from the last. It would be a perfect world (from a project planning standpoint) if every home were a cookie cutter from the previous install, however this is not always the case. I have been in the construction industry doing remodeling and even building new residential homes for over 25 years. Along the way I have run into some interesting situations in which I was not prepared and wished I was. Although this has been sometimes fun and challenging at times,…Continue
It is all ways great advice for small businesses to diversify, I know it pulled our company through a recession and is solely responsible for us coming up on our 20th year in business. With home improvement companies and electrical contractors, the advantages of being a Certified Infrared Thermographer go far beyond diversifying the small business…Continue

Lets face it – building science is pushing the performance of adhesive tapes to a new levels and though I can’t profess to have my daughters’ ability in making fashionable duct tape purses, I have been know to mis-apply good tape to get me out of a bind! I think Red Green would be impressed!
If you send me your photos, I…Continue
Thermostatic Expansion Valves (TEV or TXV), one of the most popular metering devices for residential, high-efficient air conditioning and heat pumps, have performed almost impeccably for decades. Unfortunately, some manufacturers in the past few years have identified batches of valves that have had high superheat issues. Have we just been blind for so long, not realizing these problems existed? Or have these valves really been so reliable for such a long time?
If you think you…Continue
I am a whole house fan and attic ventilation expert in Temecula CA. I started studying whole house fans in 2008 when my wife, Darlene, and I moved from Manhattan Beach. I would really like to share my knowledge with all of you but I want to be sure I don't antagonize you with more commercialization than you want. Please let me know your opinion and if you can, send me some examples of acceptable blogs and unacceptable ones.
For as long as I can remember, the agreed epidemic with ductwork was always undersized return ducts. Although we are far from perfect with duct sizing in New England, I have frequently seen great strides in fixing this issue - particularly with replacement systems. Lets face it, you should just be properly designing the duct system on new installations. Undersized ducts cause great restrictions in airlfow, raising…Continue

Homeowners are often aware of the different problems they experience in their homes: uncomfortable rooms, high utility bills, poor indoor air quality, etc. However, homeowners are generally unfamiliar with the concept of Home Performance, the Whole House approach, and how energy efficiency upgrades can address these concerns. We regularly hear these stories and find that by listening, asking the right questions, educating, and providing guidance, we can help homeowners feel…Continue

On the flight home from ACI’s 2014 National Home Performance Conference, I read Charlie LeDuff’s Detroit: An American Autopsy. It’s a gritty, sad story about the decline of one the greatest U.S. industrial cities. It was fitting that ACI’s conference was held in Detroit–thanks to the growth of the auto and wartime industries in the early 20th century, Detroit was the birthplace of the U.S. middle class. But according to LeDuff, Detroit, which “once led the nation in home ownership,…Continue

Let me first start by confessing my guilt... Guilt for being bored easily, guilt for wanting praise, even if it is a pat on my own back for an achievement... Guilt for being a millennial... On the other hand I enjoy working in teams and I encourage frequent communication between all team members from admin staff to auditors, sales staff and crew members to improve our workflow. Yes, I am a millennial, but let me add that there is nothing that makes me cringe more than the excuses I get from…Continue

The Residential Energy Services Network (RESNET) announced its collaboration with the International Code Council last week in an effort to help home builders transition to the new 2015 International Energy Conservation Code (IECC). In the upcoming version of the residential building code, RESNET's HERS Index will be an optional compliance path — some people are saying that this compliance path represents the most significant change coming to 2015 IECC.
What is the…Continue

Cities grafting green-building certifications like LEED into commercial building codes is nothing new, and a number of places like Dallas, Atlanta, Boston and Scottsdale have had such requirements in place for a decade or more.
What’s happening now is that cities are doing likewise with…Continue
