What red flags should I watch for hiring an HVAC contractor in Allentown?
Check that any Allentown 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 Allentown, 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. For older Allentown homes (average 51 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.
