Stuff Burlington ductwork contractors ask before they sign up
Does this respect VT code, or do I have to re-cut every quantity?
Counts assume IRC R301.2 / IECC Zone 5–6 (frost depth 48–60 in., ice-shield 36 in. past wall, historic district overlays). VT doesn't license hvac ductwork at the state level, so the variability comes from local amendments. Quantities are correct; you adjust crew rates and local permit assumptions in the bid summary.
How do you handle complex duct layouts and routing?
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 healthcare work in Burlington, the typical correction is one or two assemblies — not redoing the whole thing.
What about nor'easters bring heavy snow and wind?
Oil and propane furnaces common in rural areas. Heat pump conversion incentives available. Ductless systems for older homes without ducts.
How much does a permit add to a hvac ductwork job around here?
Plan on $200–$5,000 in Burlington, with review running 3–7 weeks. Build that into general conditions so a slow plan-check doesn't eat your overhead. Insurance and bond are separate carrying costs.
