Thermal precision for homes with history.
We specialize in preventative maintenance contracts for legacy radiator-heat and vintage air-conditioning systems built between 1920 and 1970. Our work anchors in meticulous diagnostics, seasonal tune-ups, and the specific engineering of your building's age.
Serving owner-occupied homes and apartment buildings across New England's mill towns, coastal neighborhoods, and historic districts. Based in New Bedford, Massachusetts.
Explore Our ServicesWhy Radiator Systems Matter
Properties built in the era of steam and hot-water radiators benefit from fundamentally different thermal principles than modern forced-air systems. These systems often run for decades with minimal intervention if maintained correctly. A boiler installed in 1952 isn't obsolete—it's engineered for slow, steady heating with predictable water-circulation patterns and passive distribution.
Yet most HVAC contractors today treat them as legacy liabilities. We treat them as what they are: resilient infrastructure worth understanding and preserving. Seasonal maintenance—flushing sediment, adjusting pressures, inspecting expansion tanks—extends the operational life of radiator systems by 15–20 years compared to reactive repairs alone.

Our Service Categories
Seasonal Tune-ups
Pre-winter and pre-summer diagnostics on boiler output, thermostat calibration, radiator flow rates, and combustion safety. Includes sediment flushing and pressure-relief testing.
Learn moreAnnual Inspections
Comprehensive system assessment including thermal imaging of distribution lines, boiler efficiency curves, and a detailed written report with findings and next steps.
Learn moreBoiler Servicing
Internal cleaning, burner adjustment, flue-gas analysis, and scale removal. Includes parts replacement and a post-service efficiency certificate.
Learn moreRetrofit Planning
If replacement is necessary, we work with you to evaluate heat-pump retrofits, hydro-air conversion, or a new high-efficiency boiler—all with minimal structural disruption.
Learn moreRadiator Repair & Balancing
Room-by-room pressure balancing, trap replacement, airbleed calibration, and restoration of cast-iron radiators. Includes thermostatic valve repair and thermometer tape installation.
Learn moreEmergency Response
Same-day dispatch for heating loss, boiler shutdown, or acute system failure. 24/7 availability during winter months (November–March).

Serving New England's Historic Neighborhoods
We maintain HVAC systems in the historic mill districts of Massachusetts, Connecticut, and Rhode Island—neighborhoods built during the textile, manufacturing, and maritime booms of the 19th and early 20th centuries.
Our clients include owner-operators of multi-family properties on New Bedford's Elm Street historic district, homeowners in documented heritage properties, and property managers who understand that a 1930s steam system, properly maintained, is an asset worth preserving.
Based at 247 County Street in New Bedford's downtown, we're integrated into the local building community and familiar with the specific challenges of New England's climate zones, building codes, and historic-preservation guidelines.
