Furnace repair cost by part.
Typical Greenwich repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Greenwich, CT, furnace repair costs reflect the area's older homes (median built 1956) and cold-climate demands (Zone 5A). Typical diagnostic fees run $70–$175, with common repairs like flame sensor ($75–$225) or blower motor ($375–$1,400). Connecticut requires a mechanical permit for most furnace work, which adds to the total. Many homeowners consider dual-fuel systems for efficiency, especially with federal 25C tax credits available (30% up to $2,000 for qualifying heat pumps). Energize CT rebates require a Heat Pump Installer Network (HPIN) registered contractor. Given the mixed heating climate, a well-sized furnace or heat pump is key.

Recommended unit for Greenwich
Given Connecticut’s cold climate and mixed heating, dual-fuel (cold-climate heat pump + gas furnace) is the sensible default for most Greenwich homes. The cooling season is short, so the budget is better spent on heating efficiency than on ultra-high SEER2. A pro can confirm the right size and system for your home with a load calculation.
