I've had people from Alaska to Manhattan asking where to find an HVAC installer who even understands how to read a Manual J calculation, and just assuring them that 'they're out there' is getting boring.

Whole House Fan Mythbusting

You know what I don’t like? When people try selling one product across America with pseudoscience or vague claims about benefits in home physics, chemistry, or microbiology. Here’s my rebuke to one specific instance of this kind of over-stated marketing in the world of ‘cooling your house as cheaply as humanly possible’.
