AfterHVAC Company in Boston, MA
Most HVAC calls in Boston aren’t standard tune-ups. They’re repairs and retrofits in triple-deckers, Federalist row houses, and brick Victorians built between the 1880s and 1920s, where the original heating system is steam or gravity hot water and there’s no ductwork to speak of. We dispatch from our Boston office and carry parts for Rheem, York, Daikin, and Bryant systems, but we also stock steam valves, pressuretrols, and radiator air vents because half the city still heats with technology most modern HVAC programs barely teach. If your heat goes out when the polar vortex pushes Boston below 9°F, or your third-floor rental needs cooling without tearing apart plaster walls, call us at (984) 538-9003.
Why Boston Homes Are Different
Boston’s residential stock is overwhelmingly pre-WWII. Dorchester, Roxbury, Jamaica Plain, South Boston, and East Boston are dense with triple-decker multi-family homes built with one-pipe or two-pipe steam heating and zero ductwork. That means HVAC work here centers on obsolete technology, steam system diagnostics, boiler near-boiler piping, radiator air-vent sizing, pressuretrol calibration, plus the extreme complexity of retrofitting cooling into buildings with no air-distribution infrastructure.
Ductless mini-split systems have become the dominant cooling retrofit solution because running duct through a triple-decker is often structurally and financially impractical. In Back Bay and Beacon Hill, the Boston Landmarks Commission prohibits mounting condensing units or mini-split heads on street-facing facades, forcing our techs to route refrigerant lines through interior stairwells and out to rear alley walls or rooftops. An install that might take four hours in a suburban ranch routinely becomes a two-day job requiring masonry core-drilling and custom line-hide work.
Climate extremes matter too. Boston’s ASHRAE 99% design heating temperature sits around 9°F, with real polar vortex events dropping below 0°F. Heat pump sizing and defrost-cycle performance are critical. Massachusetts’s Mass Save program has driven aggressive adoption of cold-climate heat pumps like Mitsubishi Hyper-Heat, and contractors who aren’t enrolled as Mass Save partners leave substantial rebate money on the table for customers. Summers bring sustained humidity and heat-index events above 95°F, so systems must be engineered for both extremes.
Our Main Boston Services
These are the three services Boston homeowners call us about most. Each has its own page with deeper detail on pricing, common problems, and what to expect.
AC Repair in Boston
AC repair in Boston usually means one of three scenarios: a conventional central air system in a newer building, a ductless mini-split retrofit in a triple-decker, or a failed window unit that was never meant to handle sustained humidity above 95°F. We see refrigerant leaks from vibration-damaged line sets in Jamaica Plain, failed compressors in South Boston row houses where condensers bake on flat roofs, and clogged condensate drains in Back Bay basements. Our techs carry digital gauges, refrigerant, and electrical components for same-day diagnosis. AC Repair in Boston
Furnace Repair in Boston
“Furnace” in Boston often means a steam or hot-water boiler, not a forced-air furnace. We repair gas-fired steam boilers in Dorchester triple-deckers where pressuretrols have drifted out of calibration, replace failed circulator pumps in Roxbury gravity hot-water systems, and fix ignition modules in newer high-efficiency condensing boilers in South Boston condos. We also handle true forced-air furnace repair in post-war buildings and retrofitted systems. Every repair starts with a written price and ends with a written 365-day guarantee.

AC Maintenance in Boston
AC maintenance in Boston is seasonal survival planning. Our tune-ups cover coil cleaning, refrigerant level checks, drain line clearing, and electrical connection tightening, but we also inspect mini-split line-hide for UV damage and check condensate pump operation in basement installations where flooding is a real risk. For central air in older homes, we measure static pressure and airflow because retrofit ductwork is often undersized. We do not sell maintenance plans that lock you in, just honest reporting on what we find. AC Maintenance in Boston

What pushes Boston prices toward the high end: masonry core-drilling for line sets in Landmarks Commission districts, custom line-hide work on historic facades, and the extra labor of routing refrigerant through interior stairwells in triple-deckers. Every job still begins with a written price before any work starts, no exceptions.

Yes. Steam and gravity hot-water systems are still common in Boston’s triple-deckers and pre-WWII housing stock. Our techs carry pressuretrols, radiator air vents, and steam valves because we encounter this technology regularly, not as a specialty afterthought. Call (984) 538-9003 to discuss your system.

- Nora T."AC stopped cooling on a hot afternoon. Tech arrived with a badge, checked the capacitor, found it bad, and replaced it on the spot. House cooled down within the hour."
- Steve P."Furnace ignitor went out on a cold morning. Part was on the truck, installed in thirty minutes."
