What red flags are common when hiring an HVAC contractor in Durham's growing market?
Check that any Durham contractor doing HVAC replacement carries both general liability insurance ($1M minimum) and workers' compensation. Request certificates directly from the insurer, not just copies the contractor provides. In Durham, 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. Durham's rapid growth attracts out-of-state contractors who follow the boom. Verify any unfamiliar company's local licensing, physical address, and track record. Fly-by-night operations leave when the market cools.
