Dedham is one of the oldest towns in Massachusetts, and its housing stock reflects that history. The Village neighborhood and Precinct One are home to some of the town's earliest houses, including structures dating back to the 1700s. These older homes often have outdated heating equipment, uneven temperatures from room to room, or no central cooling at all. Dalelis specializes in working with these kinds of properties, whether that means retrofitting a ductless mini-split system into a historic colonial on Court Street or replacing an aging steam boiler in an East Dedham two-family.

In neighborhoods like Greenlodge and Oakdale, the housing trends newer. Many of the 1950s-era homes here run forced hot air systems that may be 25 or 30 years old. If your furnace in the Greenlodge area is making unusual noises or your AC near Legacy Place is not keeping up on hot days, those are signs it is time for a professional diagnosis. We also handle new construction HVAC for Dedham's ongoing residential projects, including system design, installation, and permitting.

Dalelis is based in Norwood, roughly 5 miles south of Dedham Square, so we are never far when you need us. We work on all major brands of furnaces, air conditioners, boilers, and heat pumps. Our technicians are licensed, insured, and trained to handle everything from a routine seasonal tune-up to a full heating system replacement. Dedham homeowners have been calling us for years because we show up on time, charge fair prices, and stand behind our work.
