What inspections to expect
Most residential HVAC jobs get two inspections:
1. Rough inspection — gas piping, venting, electrical, condensate routing before insulation/closing walls 2. Final inspection — fire-up, combustion analysis, CO test, equipment match to permit
A Certificate of Compliance is issued once it passes.
Why this matters at resale
Westchester real-estate attorneys flag unpermitted mechanical work during title searches. We've seen closings delayed 60+ days because a previous owner installed a boiler without a permit. Resolving it after the fact means:
- Open inspections of completed work
- Possible re-work to current code
- Back-fees and penalties
- Sometimes full equipment removal and reinstall
This costs sellers $2,000–$15,000+ at closing time.
Red flags from contractors
- "We don't pull permits — saves you money"
- "You pull the homeowner permit yourself" (illegal in Westchester for HVAC)
- Quote that doesn't itemize the permit
- "We can do the work, then permit it later"
- "Inspection will fail — we'll just skip it"
