Heating and cooling in Connecticut
Heating dominates the energy bill. Gas furnaces and boilers are the norm, with summer AC and growing use of cold-climate heat pumps.
Connecticut licenses heating, piping and cooling contractors through the Department of Consumer Protection, with separate license classes for heating and for air conditioning work. Town building officials issue permits.
Older Connecticut homes rely on oil and gas boilers, many without ducts. Ductless heat pumps are a popular way to add cooling, and coastal storms can affect outdoor equipment along the shoreline.
Before replacing an oil system, ask the contractor how the old tank will be handled and whether a permit covers the removal.
Fairfield County homes near New York have higher equipment costs and more central AC, while older cities like Hartford, New Haven and Waterbury rely heavily on boilers. Oil-to-gas and oil-to-heat-pump conversions are common across the state.
