For 2026, most New Haven County homeowners pay within these ranges for professional, installed work. Home size, existing ductwork or radiators, fuel type, and electrical service move the number — but these are the honest starting figures before anyone walks the basement.
Typically $5,000–$9,000 installed for a high-efficiency gas furnace. The straightforward swap for the many New Haven-area homes already on forced-air gas heat.
Typically $6,000–$10,000 installed. The right call for the radiator-heated Victorians and triple-deckers that dominate older New Haven neighborhoods.
Typically $8,000–$15,000 installed, depending on zones and electrical work. Heating plus cooling in one system — and the usual answer for homes with no ductwork at all.
Typically $5,000–$9,000 installed where ductwork already exists. For radiator homes without ducts, ductless mini-splits usually beat forcing in new ductwork.
Most repair visits land in the $150–$350 range for diagnosis and minor parts; bigger component failures run $400–$800. A repair quote near half the replacement cost on old equipment is usually a replace signal.
Conversion work beyond the unit itself — gas line, chimney liner, oil tank removal — typically adds $2,000–$5,000+. Oil tank removal alone runs $1,500–$3,000 in Connecticut.

A heating system that works fine in a newer suburb can be the wrong answer on the New Haven shoreline, and the reason is the housing stock. Much of the city was built before central air existed, and the surrounding towns each add their own wrinkle:
We built this site to give New Haven County homeowners the context contractors don’t always volunteer: real price ranges, honest system trade-offs for the homes here, and what questions to ask before anyone touches your boiler.

Heating demand peaks the week the first real cold snap hits, and the best contractors’ schedules fill fast.
