HVAC Company in Boston, MA
Boston HVAC work carries a different set of demands than most New England suburbs do. The housing stock is older, the mechanical rooms are tighter, and the seasons punish systems that aren’t maintained. Dalton Heating & Air handles AC repair, heat pump installation, and furnace repair across Boston with written pricing, on-time arrival, and a full-year written guarantee on every repair. Call (361) 306-9515 and you’ll get a live person, not a voicemail queue.
Why Boston Homes Are Different
Boston’s housing stock runs from 19th-century triple-deckers in Dorchester to converted loft buildings in South Boston to mid-century ranches out toward West Roxbury. That range matters because the mechanical room in a triple-decker is often a converted closet with a furnace jammed in sideways and ductwork that was retrofitted around load-bearing walls. We work in those tight spaces regularly, and we plan for them before we arrive.
The climate is the other factor. Boston summers now hit the mid-90s with humidity that forces AC systems to run longer cycles than they were sized for twenty years ago. Winters push furnaces through sustained cold snaps where a system that fails at 2 a.m. means a house dropping below 50 degrees by morning. Units in this city get worked harder than systems in milder parts of the state, and that changes which repairs show up most often, and when.
Permits are a real part of Boston jobs. Work that touches gas lines or electrical panels in the city of Boston typically falls under city inspection requirements, and we handle that paperwork as part of the job, not as an afterthought.
Our Main Boston Services
These are the two calls we get most from Boston homeowners, and each service has its own detailed page covering pricing, common failures, and what to expect on the day of the job.
AC Repair in Boston
Boston AC failures stack up differently than they do in the suburbs. We regularly find condenser units sitting in tight side yards or on roof decks where heat rejection is poor and coils clog faster. Refrigerant leaks, failed capacitors, and frozen evaporator coils are the three most common calls we run in this city. Every repair gets a written diagnosis before any work starts, and every repair is guaranteed in writing for a full year. Full details on AC Repair in Boston.

Heat Pump Installation in Boston
Heat pumps are gaining ground in Boston for a practical reason: they handle both cooling and heating in a single system, which matters when you’re working with limited mechanical space. The local challenge is sizing. Boston homes built before 1980 often need insulation upgrades before a heat pump will hold temperature efficiently, and we’ll tell you that honestly before quoting an install. See Heat Pump Installation in Boston for full pricing and process.

Furnace Repair in Boston
Furnace work in Boston means dealing with older gas lines, tight basement clearances, and the particular wear patterns of systems that run hard from November through March. We handle everything from failed igniters and pressure switches to full heat exchanger evaluations. The repair is priced in writing before we touch anything. Details on Furnace Repair in Boston.

Brands We Service in Boston

Pricing for HVAC Company in Boston, MA
| Service | Typical range in Boston |
|---|---|
| AC repair | $175 – $765 |
| Furnace repair | $175 – $825 |
| AC installation | $4,130 – $8,850 |
| Tune-up | $95 – $235 |
What pushes a Boston job toward the top of those ranges is usually access and age. A condenser on a South Boston roof deck takes longer to work on than one in a ground-level yard in Hyde Park, and a furnace installed in a converted closet adds labor time. That’s exactly why we put the price in writing after we see the equipment and before any work begins. The number on the quote is the number you pay.
