Is Following Manual D Expensive?
Builder here. Heard something today I had not heard before from an HVAC contractor and soliciting feedback from all.
My HVAC contractor told me that following the process of a Manual D resulted in duct work that was expensive. It seemed from what he said he was implying material costs, but in this tight labor market, I could assume that meant labor costs as well.
I’ve never performed a Manual D myself, but have worked with other contractors that I know did do them. I’ve not noticed anything cheap or otherwise appearing different/cost-effective about the duct work with this contractor than those other contractors
Apart from comments along the lines of, “not doing it right is always more expensive” – is there any basis in this statement, or is he just not doing the Manual D correctly?
