The List of HVAC Installers Who Respect Science and Math
Welcome to The List. It's free to view, free to be listed on, I have no interest in stealing anyone's information or making a few bucks on a kickback:

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. Here is a FREE directory of those people, SELF-SELECTED. I am NOT vetting them. They vet themselves.
Good luck to us all.
