Furnace repair cost by part.
Typical New London repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair costs in New London, Connecticut, typically range from $65–$175 for a diagnostic fee, plus labor and parts. With a median home age of 83 years, many systems require specialized attention. Local contractors must pull mechanical permits for work involving gas, oil, or major electrical components, which can add to the total. Connecticut's cold climate (Zone 5A) means proper sizing and dual-fuel setups are often recommended for efficiency. Given the area's moderate cooling demand, a heat pump paired with a furnace can be a practical upgrade, especially with federal 25C tax credits available.

Recommended unit for New London
Given Connecticut’s cold climate and mixed heating, dual-fuel (cold-climate heat pump + gas furnace) is the sensible default for most New London 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.
