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?

  If you think you…

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…

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,…
