How HVAC replacement costs vary in Maine
State-specific code or insurance rule: Maine uniquely splits HVAC licensing across two boards — the Oil & Solid Fuel Board licenses combustion-equipment installers (oil furnaces, biomass) while the Plumbing & Mechanical Examiners regulate refrigerant work — and Efficiency Maine's heat-pump rebate of $2,400 per ton at 100% AMI is among the most generous in the country.
