Heating Systems We Service in Lexington, MA
Whether it is a gas furnace in a newer colonial or an oil-fired boiler in a center-of-town classic, we service the full range of equipment installed around Lexington:
Gas, oil and propane furnaces
Steam and hot water boilers
Ductless and ducted heat pumps used for supplemental heat
Zone valves, circulator pumps and expansion tanks
Thermostats, aquastats and low-water cutoffs
Combustion and venting systems tied to chimneys or direct-vent equipment
Uneven heat is the most common complaint we hear across Lexington, MA, whether it comes from a boiler system with air trapped in the lines or a furnace with a duct run that was never balanced correctly.
Air-bound zones and radiators that bang
Banging or hissing radiators usually mean air trapped in the system, not a failing boiler. We bleed zones, check circulator pumps, and confirm the expansion tank is holding pressure before we touch anything bigger.
Cold rooms at the end of long duct runs
Rooms that never seem to catch up to the thermostat often sit at the end of an undersized or leaky duct run. We test static pressure and airflow rather than guessing, which helps solve a no heat repair in Lexington, MA, permanently instead of temporarily.
Circulator pumps and zone valve failures
A boiler that runs but never delivers heat to one zone often points to a stuck zone valve or a circulator pump that has quietly failed. Boiler repair Lexington, MA visits usually start here before we look at the boiler itself, and it is one of the most common heating repair Lexington, MA calls on our board each winter.
When a furnace or boiler is past the point of another repair, we walk you through heating installation Lexington options rather than defaulting to the same fuel type you already have. Furnace replacement Lexington projects and boiler swaps both start with a free estimate, and we size new equipment to the home, not the old ductwork or piping.
Oil and propane systems in outlying areas
Some Lexington properties, especially outside the town center, still run on oil or propane. We service these systems directly and can lay out realistic options if you are considering a conversion to gas or a heat pump.
Chimney liner and venting evaluation
Swapping to a higher-efficiency furnace or boiler often changes venting requirements. We check chimney liners and venting paths as part of any replacement quote so there are no surprises after installation.
Heating Challenges Specific to Lexington
Lexington homes feature a wide variety of architectural styles, so heating maintenance needs vary significantly from neighborhood to neighborhood. Near Lexington Center, historic residences often rely on older, sectioned boilers and original radiators designed for less-insulated spaces.
Mid-century modern properties in neighborhoods like Turning Mill and Peacock Farm frequently utilize hot water baseboard heating, sometimes paired with ductless heat pumps to resolve stubborn cold spots. Meanwhile, larger modern colonials across town typically use multi-zone forced-air gas furnaces, where comfort issues usually stem from airflow imbalance rather than system failure.
Because Pespisa Company handles heating, cooling, and plumbing, a heating contractor in Middlesex County, MA can also flag a related plumbing or cooling issue tied to the same mechanical room — a leaking expansion tank, a failing circulator, or an aging water heater sharing space with the boiler.

Frequently Asked Questions
Furnace replacement cost in Lexington depends on the size of the home, the number of zones, and whether ductwork needs updating. We provide a free, in-person estimate before scheduling any work so the number you get reflects your actual home.
Yes. We evaluate fuel conversions for Lexington homes on a case-by-case basis, looking at gas availability, existing ductwork or piping, and whether a heat pump could handle part or all of the load before recommending a direction.
Banging or hissing radiators are almost always trapped air in the zone, not a failing boiler. We bleed the affected radiators and check the expansion tank and circulator pump to make sure the noise does not come back.
Most heating equipment across Middlesex County benefits from a fall tune-up and combustion check once a year, before the coldest weather arrives. Boilers and furnaces that run hard all winter hold up better with that annual visit.
We do. Steam boilers in older Lexington properties need different attention than hot water systems — proper water level, working low-water cutoffs, and clean venting — and we service both types regularly.
Rebates for heating upgrades in MA change from year to year and depend on the equipment installed, including options tied to the Mass Save program for qualifying heat pump installations. Call us, and we will confirm what currently applies to your project.
Often, yes. Cold rooms are frequently a duct, damper, or zoning issue rather than proof the whole system needs replacing, and we diagnose airflow and balance before ever recommending a full replacement.
