AfterHVAC Company in Medford, MA
Dalton Heating & Air is an HVAC company serving Medford, MA homeowners with repair, installation, and service work priced in writing before anything begins. Medford’s housing stock runs older than most Middlesex County communities, and that shapes almost every call we take here. Triple-deckers off Salem Street, capes and colonials in West Medford, condos converted from 1920s two-families in South Medford: each one puts different strain on a furnace or condenser. If you need honest answers about your system, call (361) 306-9515.
Why Medford Homes Are Different
Medford sits on the Mystic River with sharp elevation changes between hillside neighborhoods and the flats near the river. That terrain shows up in the work: a furnace in a hillside home off High Street often sees longer run times in January than one in a riverside two-family, because cold air pools against the foundation. Older homes dominate the city, and many still run ductwork sized for coal-fired gravity systems or early forced-air conversions. When a homeowner calls us about uneven heating between a finished third-floor bedroom and a first-floor living room, the duct sizing is usually the culprit, not the furnace itself. Humid summers near the Mystic also mean AC systems in Medford run harder in July and August than inland systems do, so condenser coils need cleaner airflow to keep head pressure down.
Permits matter here. The city requires a permit for most HVAC replacements, including furnace swaps and full AC change-outs. We pull the permit as part of installation work and handle the inspection scheduling. No homeowner should have to chase the building department themselves.
Our Main Medford Services
Most Medford homeowners call us for one of three reasons: an air conditioner that quit in July, a furnace that will not fire in February, or a heat pump that makes more sense than riding a 30-year-old boiler for another season. Here is what each job looks like in Medford.
AC Repair in Medford
Medford summers are short but heavy, and a failed central air system in a triple-decker off Fulton Street makes for a brutal few days. We diagnose the system as a whole: refrigerant charge, electrical connections, condenser airflow, and duct condition. Many Medford AC repairs trace back to neglected filters and coils that froze over, especially in homes where the air handler lives in a tight basement closet. We service all nine major residential brands and stock common capacitors, contactors, and pressure switches on our trucks. AC Repair in Medford covers pricing, common failures, and what a same-day visit looks like.
Heat Pump Installation in Medford
Heat pumps fit a lot of Medford’s housing stock well, especially homes with electric baseboards or an aging oil boiler. A ducted heat pump can replace window units in a colonial, and ductless systems work well in converted two-families where running new ductwork would mean tearing into lath and plaster. Medford winters occasionally dip into single digits, so we recommend cold-climate models sized for the city’s design temperature rather than a best-guess rule of thumb. Heat Pump Installation in Medford explains equipment selection, rebates, and what a realistic install timeline looks like.
Furnace Repair in Medford
Furnace failures in Medford spike in January and February, and most involve either an ignition issue or a safety limit that is doing its job. The older the unit, the more likely the heat exchanger deserves a hard look. We test for carbon monoxide on every furnace call, and if the heat exchanger is compromised, we red-tag the unit and show you the evidence before recommending replacement. Homes along Winthrop Street and the hillside streets off it tend to run furnaces hard from November through March. Furnace Repair in Medford covers pricing by part and what our written guarantee covers.

Brands We Service in Medford
Our technicians are factory-trained on Trane, Lennox, Goodman, and Rheem equipment, among others, and we carry common parts for all four on our trucks. That means fewer return trips to a supply house and a faster fix when a furnace quits on a cold morning. See our brands for the full list and what each one means for repair cost and part availability.
Pricing for HVAC Company in Medford, MA
| Service | Typical range in Medford |
|---|---|
| AC repair (diagnostic and common part) | $150 – $650 |
| Furnace repair (ignition, limit, or gas valve) | $150 – $700 |
| Complete AC installation | $3,500 – $7,500 |
| Seasonal tune-up (AC or furnace) | $80 – $200 |
What pushes a Medford job toward the top of those ranges is usually access or age. A furnace crammed into a 1920s basement with a low ceiling takes longer to work on than one in an open utility room. The single biggest variable in AC installation is equipment efficiency and whether the existing ductwork can stay. Whatever the number, you get it in writing before any work starts, and every repair carries a written guarantee for a full year.
