Portland's cold winters make heating the priority for most homes, though summer humidity has pushed more Mainers toward heat pumps and central air in recent years.
Modern cold-climate heat pumps perform well even in Maine winters and can lower heating costs. Run the numbers with our Heat Pump Savings Calculator.
Costs vary by fuel type — oil, gas, or electric. Estimate yours with our Furnace Replacement Cost Calculator.
Maine doesn't require a state HVAC license for most work, though electrical portions require licensing through the state's Electricians' Examining Board — ask any contractor about their credentials directly.
