TECHNICAL CAPABILITIES

COMMERCIAL & RESIDENTIAL SCOPES

Heavy-duty equipment installations, diagnostics, and code modernizations across Lawrence.

SCOPE // 01

24/7 Emergency Heating & Cooling Repair

When a furnace dies on the coldest night of the year or an AC quits during a July heat wave, our on-call technician is dispatched around the clock — evenings, weekends, and holidays included. We arrive with stocked trucks to diagnose and repair most gas furnaces, boilers, and central AC systems on the first visit.

SCOPE // 02

Heat Pump & Mini-Split Conversions

Ductless high-efficiency heat pumps deliver zoned heating and cooling that can dramatically cut energy costs in homes without existing ductwork. We design and size the system to your home's layout, handle the full installation, and complete the documentation required for Mass Save rebate compliance so you capture the incentives you qualify for.

SCOPE // 03

Steam & Hot Water Boiler Tune-Ups

Lawrence's older housing stock relies heavily on steam and hydronic boilers that need expert seasonal care. Our tune-up includes cleaning the burner assembly, testing safety controls and low-water cutoffs, checking radiator vents and near-boiler piping, and tuning combustion for efficient, even heat all winter.

SCOPE // 04

Seasonal Maintenance & AC Service

Annual precision maintenance keeps equipment running at manufacturer-spec efficiency and catches small failures before they become mid-season breakdowns. We clean coils, verify refrigerant charge, test airflow and thermostats, and provide a clear written report on the health of your system.
