What red flags should I watch for hiring an HVAC contractor in Boston?
In Boston, verify your HVAC replacement contractor pulls the permit themselves — never pull it in your own name. If they ask you to pull the permit, they may not be properly licensed to do the work. Be cautious of HVAC replacement contractors in Boston who pressure you to sign same-day. Legitimate contractors expect you to get competing bids and will hold their price for 30 days. High-pressure sales tactics correlate with inflated pricing. For older Boston homes (average 55 years), beware of HVAC replacement quotes that don't mention code compliance. Modern codes have changed significantly since these homes were built — any work that triggers inspection should be priced with code upgrades included.
