Expert Solutions for Weymouth Homes

From scheduled maintenance to major infrastructure overhauls, executed to the highest trade standards.

01

Heat Pump Mini-Split Conversions

We replace costly window units and aging baseboard heat with ductless and ducted cold-climate heat pump systems, performing full Manual J load calculations so each zone is sized correctly for our coastal Massachusetts winters. Conversions include proper line-set routing, condensate management, and commissioning to manufacturer specs for maximum efficiency and rebate eligibility.

  • ✓ Code-compliant installation
  • ✓ Upfront agreed pricing
  • ✓ Workmanship warranty included
02

Mass Save Rebate & Efficiency Compliance

Navigating Mass Save paperwork shouldn't fall on the homeowner. We specify qualifying equipment, document AFUE/HSPF ratings, and file the required verification so your heat pump, boiler, or insulation project clears inspection and locks in the available rebates and 0% HEAT loan financing.

  • ✓ Code-compliant installation
  • ✓ Upfront agreed pricing
  • ✓ Workmanship warranty included
03

Steam & Hydronic Boiler Tune-Ups

Older homes in Weymouth, Brookline, and Newton often still rely on steam boilers that need a knowledgeable hand. We skim the water line, flush low-water cutoffs, balance radiator air vents, and tune burner combustion — fixing the banging, short-cycling, and uneven heat that generic service visits leave behind.

  • ✓ Code-compliant installation
  • ✓ Upfront agreed pricing
  • ✓ Workmanship warranty included
