Stuff San Antonio hvac contractors ask before they sign up
Does this respect TX code, or do I have to re-cut every quantity?
The takeoff doesn't pull a permit for you — that's still on whoever holds the HVAC Contractor License — but the assemblies match what TX inspectors look for.
How do you handle manual load calculations take forever?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For residential work in San Antonio, the typical correction is one or two assemblies — not redoing the whole thing.
What about site conditions?
Build the local condition into your assembly defaults once, and it carries forward to every San Antonio bid afterward.
