The downside of all this is who ends up paying for this attitude, Who ends up paying for this guy to not be held up and he's just going to go with some cheap guy that's doing it on the side and is not going to do everything properly. It's the homeowner that ends up buying that home in the end and that.

Local codes need to require better grade HVAC and installation vs. "Contractor/Builder grade".
