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!

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?

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
