Pricing
HVAC costs in Greater Boston typically range from $150–$500 for repairs, $4,000–$12,000 for AC or furnace installation, and $8,000–$25,000 for full system replacements. Heat pumps run $4,000–$20,000 before MassSave rebates of up to $8,500. Actual costs depend on home size, system type, and installation complexity.
HVAC pricing in Greater Boston varies widely because "HVAC" covers everything from a $150 repair to a $25,000 whole-home system replacement. The biggest factors are the type of work, the size and age of your home, and the efficiency level of the equipment. Greater Boston also tends to price slightly above the national average due to higher labor and permitting costs and the complexity of working in the region's older housing stock. The ranges below reflect typical 2026 pricing so you can budget with confidence and recognize a fair quote when you see one.
| Service | Typical Greater Boston Cost (2026) |
|---|---|
| Diagnostic service call | $75–$150 |
| Routine repair | $150–$500 |
| Central AC installation | $4,000–$12,000 |
| Ductless mini-split (per zone) | $3,000–$8,000 |
| Furnace replacement | $3,500–$8,000 |
| Boiler replacement | $5,000–$12,000+ |
| Heat pump (before rebates) | $4,000–$20,000+ |
| Full system replacement | $8,000–$25,000 |
| Emergency / after-hours call | $200–$600 + parts |
Most routine HVAC repairs in Greater Boston fall between $150 and $500, including the service call and common parts. A standard diagnostic visit typically runs $75–$150, often credited toward the repair if you proceed. Simple fixes like a capacitor, thermostat, or igniter sit at the lower end, while more involved repairs — blower motors, control boards, or refrigerant work — run higher. If repair costs approach half the price of a replacement and your system is aging, replacement usually becomes the smarter investment.
Central air conditioning installation in Greater Boston typically runs $4,000–$12,000, depending on home size, ductwork condition, and system efficiency. Homes without existing ductwork — common in older Boston properties — often use ductless mini-split systems, which run roughly $3,000–$8,000 per zone. The right approach depends heavily on your home, which is why a proper in-home assessment matters more than any online estimate.
Furnace replacement in Greater Boston generally runs $3,500–$8,000 installed, with high-efficiency models costing more up front but lowering winter energy bills. Boiler replacement — common in Boston's radiator-heated homes — typically runs $5,000–$12,000 or more, depending on the system and the complexity of the installation. Not sure which you have? Our furnace vs. boiler guide breaks it down. Both heating types should be installed by a licensed Massachusetts technician who handles the required permitting.
Heat pump systems in Greater Boston range from roughly $4,000 for a single-zone ductless setup to $20,000+ for a whole-home system before incentives. The game-changer is MassSave: qualifying whole-home installations are eligible for up to $8,500 in rebates, and the remaining balance can be financed at 0% through the HEAT Loan. After incentives, many Boston homeowners find a modern heat pump costs far less than expected — and it replaces both heating and cooling in one system.
Emergency and after-hours HVAC service in Greater Boston typically runs $200–$600 for the priority service call, plus parts. Rates are higher than standard daytime calls because of the urgent, off-hours response. Reputable contractors provide upfront pricing before any work begins. Boston Climate Co. connects you with professionals who quote transparently before they start, so an emergency never becomes a billing surprise.
Several variables move the final number: the size and layout of your home, whether usable ductwork already exists, the type and efficiency of the equipment you choose, how accessible the installation site is, and local permitting requirements. Boston's older homes often add complexity — tight basements, knob-and-tube wiring, or radiator systems that influence the approach. Efficiency level matters too: higher-efficiency systems cost more up front but reduce monthly bills and may unlock larger rebates.
The single biggest lever is incentives — MassSave rebates of up to $8,500 and 0% HEAT Loan financing can dramatically cut the cost of a heat pump upgrade. Beyond that, annual maintenance prevents the expensive emergency breakdowns that cost far more than a tune-up, and scheduling installations in the off-season (spring or fall) can mean better availability and pricing. Getting matched with a licensed, transparent contractor from the start protects you from inflated quotes and unnecessary work.
