Heat Pump & Mini-Split Conversion

We replace aging oil, propane, and electric baseboard systems with high-efficiency ductless and ducted mini-splits, performing room-by-room Manual J load calculations so each indoor head is sized and placed correctly for even, quiet heat. Cold-climate rated equipment keeps homes comfortable well below freezing while cutting heating costs dramatically.

Mass Save Rebate Compliance

Rebate paperwork is where most homeowners lose money, so we manage the entire process: pre-approval coordination, qualifying equipment selection, HSPF/SEER documentation, and post-install verification filed correctly the first time. You get the full incentive you're entitled to without chasing forms.

Steam & Hot Water Boiler Tune-Ups

Older steam systems need a specialist, not a generic furnace check. Our tune-ups include burner combustion analysis, low-water cutoff servicing, gauge glass and gasket inspection, main vent testing, and pressure and waterline adjustments that eliminate banging, short-cycling, and uneven heat on upper floors.

AC Repair, Replacement & Seasonal Maintenance

From central air that's blowing warm to a mini-split dripping inside the house, we diagnose with gauges and meters — not guesses — and quote the repair before we start. Annual precision maintenance covers coil cleaning, refrigerant charge verification, condensate line flushing, and electrical checks to prevent mid-July breakdowns.
