A legitimate contractor should be licensed by the state (in NH, look for a valid NH Electricians’ Board or Plumbing/HVAC license number; in Maine, check the Maine State Board of Boiler Rules or Electrical Examiners). They must also carry general liability insurance and workers’ compensation. Always ask for proof, good companies happily provide certificates of insurance and license numbers you can verify online.
A trustworthy quote should be written, detailed, and itemized—listing specific equipment make/model, BTU/capacity, efficiency ratings (SEER2/HSPF2), labor costs, any extras (ductwork, electrical, permits), and the total price. It should clearly state what is included and excluded. Avoid vague “lump sum” quotes or pressure to sign on the spot. Compare 2–3 similar quotes from different companies.
Most quality equipment comes with a manufacturer’s warranty of 5–12 years on parts (some offer 10-year or lifetime on compressors). A good contractor adds their own workmanship/labor warranty—typically 1–5 years (or longer with a maintenance plan). Ask exactly what is covered, how claims are handled, and whether registration with the manufacturer is required to activate full warranty terms.
