Why Your New HVAC Still Fails

Give Use A Shout

I am starting a part of The Standard series most contractors skip: ACCA Standard 12, the whole-home performance and comfort evaluation. New equipment alone does not fix a house that is fighting you. This episode walks through what the standard actually asks, envelope first, blower door testing, duct measurement, thermal imaging, and the order you fix things in so the money lands where it matters. If your house has hot rooms, cold rooms, high bills, or a system that never seems to catch up, this one is for you, whether you are in Kingfisher, Central Oklahoma, or anywhere else.
