Heating Services in Northern Westchester & Putnam County

Boiler replacement with storage tanks and hydronic heating pumps

When the temperature drops in the Hudson Valley, a heating system that quits isn’t an inconvenience — it’s a real problem. As a heating contractor homeowners across northern Westchester and Putnam County have relied on for over 45 years, DeGasperi & Son installs, repairs, and maintains boilers, furnaces, radiant floor systems, and radiators throughout both counties — the heating side of HVAC, and the part of it we have specialized in since 1980. We’re licensed and insured.

Winters here don’t ease up gradually. A furnace limping along in October can fail outright by January, and the aging boiler that skipped its tune-up is the one most likely to leave a family without heat during a cold snap. We service every major system type and brand, so whether it’s a strange noise, uneven heat, a pilot that won’t stay lit, or a full replacement, our technicians diagnose it correctly the first time.

What We Service

Boilers — installation for new construction and replacements, repair for leaks, kettling, pressure loss, and pilot issues, and routine maintenance. Past 15-20 years, replacement often beats repeated repairs, and we’ll walk you through that tradeoff honestly rather than push a sale.

Furnaces — installation sized to the home’s square footage and duct layout, since an oversized or undersized unit wastes fuel and wears out faster. When one won’t ignite, short-cycles, or blows cold, we troubleshoot ignition, blower motor, and heat exchanger rather than guess.

Radiators — steam and hot-water systems need bleeding, valve replacement, and pipe repair. Knocking, cold spots, and leaks at the base usually point to trapped air, a failed valve, or sediment, not a system that needs replacing.

Radiant floor — new installation and repairs to zone valves, circulator pumps, and tubing leaks in both hydronic and electric setups. Even warmth without the drafts and dust of forced air.

Also — thermostats matched to your system, pool heaters, commercial heating for offices and multi-unit buildings, and annual maintenance plans. Most of the failures we respond to could have been caught during a fall tune-up.

Heating Across Northern Westchester

Our work here concentrates on Somers, Yorktown Heights, Shrub Oak, and Croton Falls — older housing stock dating largely from the 1950s through the 80s, a genuine mix of gas and oil, and growing commercial development along Route 6 and Route 202.

A meaningful share of the original heating equipment in those homes is still in service, or was replaced once decades ago. Boilers and furnaces from that era reach the point where repair costs and efficiency losses outweigh keeping them running; we service them as long as it makes sense and size the replacement correctly when it doesn’t. Gas reaches much of Yorktown Heights while other pockets stay on oil, so conversions are steady work. Along the Route 6/202 corridor, we handle commercial boiler and furnace work scheduled around operating hours.

Heating Across Putnam County

The heating landscape shifts as you move through the county. Rural properties away from the few natural gas lines still run on oil, and we service oil-fired boilers and furnaces directly — burner cleaning, nozzle replacement, filter changes, combustion tuning. Where gas has since become available, oil-to-gas conversion is one of our most requested jobs; we assess the system, the property’s fuel access, and the real cost-benefit before recommending it. Outside the gas infrastructure entirely, propane is the norm, and it carries its own maintenance requirements.

Plenty of homes across the county still run boilers original to the house. Many can run longer than people expect with the right maintenance, but parts availability and efficiency losses eventually make replacement the sensible call. Around the lakes, seasonal homes sit unheated for stretches and then need to come back online reliably — and they carry more freeze risk if a failure goes unnoticed. We handle seasonal start-up and shut-down alongside repair and installation.

Towns We Serve

Our heating work starts in Mahopac, where we’ve been since 1980, and carries across the county line into Somers, Yorktown Heights, Shrub Oak, and Croton Falls, plus the surrounding stretch of northern Westchester and Putnam County. Fuel access and housing stock shift from one town to the next, so each of those pages covers what we actually find there.

Frequently Asked Questions

How often should a boiler or furnace get maintenance?
Once a year, ideally in the fall before heating season. It catches worn parts, dirty burners, and control issues while they’re still minor.

What’s the average lifespan of a furnace or boiler?
Furnaces typically last 15-20 years, boilers 20-30 with proper maintenance. Repair frequency and rising energy bills are better signals than age alone.

Is my home a good candidate for oil-to-gas conversion?
It depends on whether gas service reaches the property and on the current system’s condition. We evaluate both, since it isn’t the right move for every home.

What are my options if there’s no gas line to my property?
Most homes without gas access here run on oil or propane. We service, repair, and install both.
