I'd venture to guess that most houses in the Southern US aren't very comfortable. They are either too cold or too hot! The missing component in HVAC is Dehumidification. Ultra-Aire has a new Dehum that I think is a game changer.
Learn to decipher the codes on the window labels, and know what stats to look for in a good window (and what meets current building codes). In this video I'll explain in plain english what U-Factor means (and how to relate it to R-value), as well as the meaning to SHGC.

When you hear about a deep energy retrofit project most people think of the snowy North Eastern US. I can tell you that the strategy for a Northern remodel with energy efficiency in mind is very different that our strategy for Hot/Humid Texas. In this video I'll show you 6 things we are doing to making a dramatic difference in this 1950's slab on grade house's energy bills.

I audited a brick house this week. There's no insulation in the walls. The customer doesn't want to blow from the inside (b/c the inside walls are papered and they're concerned about how the finishes...
