The Hartford market
Hartford's Licenses and Inspections division conducts building inspections at milestones and at completion, but city pages reviewed for this site did not state whether replacing a water heater, furnace, boiler, AC or heat pump needs a permit, or who may pull one; check with the city before work starts. Its fee formula for building, electrical and plumbing permits is $50.26 for the first $1,000 of construction cost plus $30.26 for each additional $1,000, and mechanical permits were not named. Homes in historic districts need historic review before a building permit is issued. West Hartford, East Hartford and other towns run their own offices. DOE puts Hartford County in cold climate zone 5A. EIA's 2020 survey found 39% of Connecticut homes heat with fuel oil, 36% with gas, and 23% with a boiler. Energize CT runs utility rebates.
Energize CT, funded through Eversource and United Illuminating, offers heat pump rebates and is the main current incentive, since Connecticut's federally funded HEAR program had not launched in October 2026. For oil-heated Hartford homes, a heat pump can cut fuel deliveries. Ask installers whether a cold-climate model is needed for zone 5A winters, and whether the oil system will stay as backup for the coldest nights.
