HVAC Company in Dover, MA
HVAC work in Dover, MA means working on larger homes, most of them 30 to 80 years old, many with two or three zones and equipment tucked into basements and attic knee-walls where access is tight. The town’s two-acre zoning keeps houses far apart and the road network sparse, so trucks carry full parts stock rather than making supply runs. If your system is down, call (361) 306-9515 and a real person answers, day or night. We cover AC repair, heat pump installation, and furnace repair here, each with its own Dover page linked below.
Why Dover Homes Are Different
Dover sits on Metacomet Ridge, and the elevation and tree cover keep summer air moving, but humidity still settles in low-lying sections near the Charles River toward South Natick and Medfield. That means cooling systems here get sized for dehumidification as much as raw temperature drop, and undersized equipment runs constantly without drying the air. Homes built in the 1950s through the 1980s dominate the housing stock, with carriers like Rheem and Goodman still working in many basements, alongside newer Daikin heat pumps on recent additions and teardown rebuilds.
Town water is private wells for most properties, and the well pump shares the electrical panel with HVAC equipment in many homes off Centre Street, Walpole Street, and Farm Street. Older 100-amp panels are common, which affects what a new heat pump can draw. Permits run through the Dover Building Department, and the town does require mechanical permits for furnace and heat pump replacements. HOA rules matter in a few newer subdivisions near Springdale Avenue, but most Dover homes answer only to the town.
Our Main Dover Services
Three jobs make up most of the HVAC calls we take in Dover: fixing a central AC system that stopped cooling, repairing a furnace that quit or short-cycles, and installing heat pumps for homeowners converting from oil or electric baseboard.
AC Repair in Dover
Dover AC failures split between capacitor and contactor wear on older condensing units and refrigerant leaks on systems past their tenth year. Tree cover means pine needles and maple seed casings pack into condenser coils on lots along Farm Street and Centre Street, so airflow issues show up more here than in open-lot suburbs. We repair Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, and every repair comes with a written price before work starts and a written guarantee for a full year. If it fails in that time, we return at no charge. That’s the Garrison Standard. Full details on the AC Repair in Dover page.

Heat Pump Installation in Dover
Heat pump installation in Dover is often tied to fuel conversion. Homes off the gas main, especially along Walpole Street and points south toward Medfield, run on oil or propane, and a cold-climate heat pump cuts that bill while adding central air that the house never had. Sizing matters here because of the dense shade and the wide temperature swings on the ridge. We quote a fixed installation price in writing, set the install date before any deposit, and handle the rebate paperwork. See the Heat Pump Installation in Dover page for costs and scope.

Furnace Repair in Dover
Furnace repair calls in Dover cluster around November and December, when oil and propane systems fire for the first sustained stretch and old ignition parts fail. Short-cycling furnaces are the most common complaint we hear from homes off South Street and Springdale Avenue, usually tied to a failing flame sensor or a dirty filter that starves the heat exchanger. We stock common parts for York, Goodman, Rheem, and Daikin on the truck, and most furnace repairs finish in a single visit. Prices come in writing first. Full detail on the Furnace Repair in Dover page.
