Call (747) 966-3037

We understand Greenwich homes because we work in them every week. From converted summer estates near Long Island Sound to propane-dependent backcountry properties with multiple outbuildings, a Greenwich furnace repair is rarely a one-size-fits-all job. That’s why we start every visit by listening to the home: where the heat is failing, what fuel the system burns, and how the property is built. Furnace Repair is what we do, and doing it well in Greenwich means treating each property as its own system.

Key takeaways:

• Greenwich furnace repairs typically run $150-$700, with written pricing before any work begins.
• We serve all of Greenwich, including Cos Cob, Riverside, Old Greenwich, and the backcountry.
• Salt-air corrosion and multi-building estates make Greenwich repairs different from neighboring towns.
• A live person answers every call at (747) 966-3037, nights and weekends included.

Why Meadowsweet Heating & Air Is Greenwich’s Preferred Furnace Repair Company

Greenwich homeowners call us because we know what this town’s housing stock actually demands. The early-20th-century shingle-style and Tudor estates near the water, the mid-century colonials in Cos Cob and Old Greenwich, the new custom builds north of the Parkway: each has its own furnace story. We carry parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so we’re not making a second trip to a supply house while your house sits cold.

Our crews show up in uniform, background-checked, and wearing shoe covers before they step past the threshold. Drop cloths go down wherever we work. When the job is done, we send a photo of the clean-up before we leave. That’s not an upsell. It’s the Cedarwell Care Promise, and it’s been part of how we operate since 2004. Every repair is backed by our 365-Day Done Right Promise. If it’s not done right, we make it right. No fine print, no runaround.

Boiler Repair in Greenwich

Boiler repair in Greenwich often means working on older hydronic systems, and the job usually runs $150-$700 depending on what’s failed. Many of the town’s conversion-era estates originally ran steam or gravity hot-water heat, and decades of additions have left those systems with unusual static pressure and surprising stress points. Furnace Repair in Greenwich regularly involves tracing pipe runs through finished basements and crawl spaces that were never designed for modern boilers.

Circulator Pumps and Zone Valves

A failed circulator pump or stuck zone valve is the most common boiler repair we make in Greenwich’s older homes. When one zone won’t heat but the boiler fires, it’s usually a pump that’s seized or a valve that’s stuck closed. We replace both with parts rated for the system, not whatever is on the truck.

Steam and Gravity Conversions

When an original steam system has been patched into a newer boiler, we often find pressure settings that were never adjusted for the retrofit. That causes water hammer, uneven heat, and cracks in old cast-iron sections. We set pressures and verify air vents so the system runs quietly and evenly.

Gas Furnace Repair in Greenwich

Gas furnace repair in Greenwich generally costs $150-$700, and the most common fixes are ignitor replacement, flame sensor cleaning, gas valve repair, and blower motor work. In-town and coastal neighborhoods where natural gas is available account for most of these calls. In backcountry Greenwich, “gas” usually means propane, which changes the parts we stock and the checks we run.

Ignitors and Flame Sensors

A furnace that clicks but won’t light usually has a failed hot-surface ignitor or a fouled flame sensor. Both are straightforward repairs we complete on the first visit. We carry ignitors for Rheem, York, Daikin, and Bryant units, along with the other major brands we service.

Heat Exchanger Inspections

Older Greenwich furnaces, especially those in conversion-era homes where airflow was never rebalanced, can develop cracked heat exchangers. We inspect with a camera before we quote a repair, because a heat exchanger failure is a safety issue, not a patch job. If the exchanger is cracked, we’ll show you the image and walk through your options honestly.

Trusted Brands We Service in Greenwich

We service and repair furnaces and boilers from nine major equipment brands, and we keep common parts for Rheem, York, Daikin, and Bryant stocked for Greenwich-area calls. That means less waiting on a supply house run when your heat is down. Whether your system is a newer high-efficiency unit or a 20-year-old workhorse, our technicians are qualified to diagnose it correctly and repair it with the right parts. We don’t push replacement when a repair is the honest answer, and we don’t patch a dying system when replacement is the smarter long-term choice.

Common Furnace Repair Problems We See in Greenwich Homes

• Salt-air corrosion on outdoor electrical connections. In coastal neighborhoods like Old Greenwich and Riverside, capacitors, contactors, and control boards fail prematurely because salt-laden moisture eats at the connections. We use corrosion-resistant replacements wherever possible.
• Mismatched controls on backcountry estates with multiple propane systems. A single property north of the Merritt Parkway often runs three or four separate furnaces across the main house, guest cottage, pool house, and garage apartment. When controls are from different decades and there’s no unified wiring diagram, intermittent failures are hard to trace without a full-property audit.
• Cracked heat exchangers in conversion-era estates. Homes originally built as summer retreats and later converted to year-round use often have original steam or gravity hot-water systems hidden beneath additions. The resulting static pressure imbalances stress heat exchangers and cause chronic short-cycling.
• Clogged condensate lines and tripped pressure switches. We see this frequently in Greenwich’s older homes, especially where furnaces were retrofitted into basements with imperfect drainage. A clogged line trips the pressure switch and the furnace locks out, which looks like a major failure but is often a one-visit fix.
