AfterHVAC Company in Somerville, MA
Dalton Heating & Air handles HVAC work in Somerville, MA with written pricing before any work starts and a full-year guarantee on every repair. This is a city of triple-deckers, converted condos, and century-old homes, which means furnaces tucked into tight basements, condensers squeezed into narrow side yards, and ductwork that’s seen a few renovations. If your system is down, call (361) 306-9515 and a real person answers, 24/7.
Why Somerville Homes Are Different
Somerville’s housing stock runs older than most of the Boston metro. The classic Somerville triple-decker, built between 1890 and 1930, usually has a furnace in a low-ceiling basement and a condenser pad jammed between two buildings. That affects how we work: access hatches are tight, electrical panels are often a generation old, and the vibration from a badly mounted condenser will echo through two floors.
Climate matters too. Winters on Winter Hill and in East Somerville push furnaces hard from December through March. Summers are shorter but humid, and a heat pump or AC unit that’s undersized for a top-floor unit in a converted three-family will struggle to hold temperature. We size and place equipment for those realities, not for a generic New England house. Thermal cycling here means flare fittings on older linesets loosen and condenser coils take a beating from road salt, so we check both on every service call.
Our Main Somerville Services
Most Somerville calls to Dalton Heating & Air come down to two things: a furnace or AC unit that stopped working, or a household deciding to switch to a heat pump before the next season. Here’s what each involves in Somerville.
AC Repair in Somerville
Somerville AC failures in July usually trace back to heat-soaked condensers behind locked alleys, clogged condensate lines in high-humidity basements, and old breakers. We diagnose to that list first and give the price in writing before touching a component. Most repairs run $150 to $650 depending on the part, and every repair carries a written one-year guarantee. Full detail is on the AC Repair in Somerville page.
Heat Pump Installation in Somerville
Heat pump installation in Somerville means working around the same access limits as AC work, plus a bigger decision: full-home replacement versus a single-zone system for a problem floor in a multi-family. We walk through the difference in Btus, the electrical panel capacity, and the condenser placement before any equipment is chosen. The full process and what installation typically costs is on the Heat Pump Installation in Somerville page.
Furnace Repair in Somerville
Somerville furnaces are mostly gas-fired and often in basements with low clearances and older venting. Common failures are ignition control boards, pressure switches, and failing blower motors on systems pushing past their 15th year. Repairs typically run $150 to $700 here, and we carry boards and switches for major brands in the truck. Full detail is on the Furnace Repair in Somerville page.

Pricing for HVAC Company in Somerville, MA
| Service | Typical range in Somerville |

| Furnace repair | $150 – $700 |
| AC installation | $3,500 – $7,500 |

What pushes a Somerville job toward the top of those ranges is usually access: a condenser in a locked alley, a furnace in a crawlspace, or a curb-side disconnect that needs to be brought to current code. The price you’re quoted is the price you pay, in writing, before the first tool comes off the truck.
