12 Things Every Home Performance Contractor Should Have on Their Work Truck

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,…

How do You Test a TXV?

  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?

What is your opinion about members promoting products here?

Hello,

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.

Please, Make the Transition!

  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…

Lessons from Energy Efficiency Advisors: Getting Homeowners Onboard with Home Performance

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.

Detroit Rises from the Ashes

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,…
