How We Handle Furnace Service Calls
Whether your furnace is making strange noises, not heating evenly, or has stopped working entirely, our technicians can diagnose the issue and get your heat back on. We carry common parts and work efficiently to minimize downtime. If you are considering switching from a furnace to a more efficient system, ask us about heat pump options for year-round comfort.

How J&R Handles Furnace Service in China
- Summit Natural Gas of Maine serves parts of China, so gas-fired equipment is an option on streets with a main; elsewhere the choice is oil, propane or a heat pump.
- About 61% of China homes heat with heating oil. Oil work is done to NFPA 31, gas and propane to NFPA 54 and 58, and every chimney or vent connection to NFPA 211.
- After any furnace service job we check for carbon monoxide detectors near the bedrooms, as Maine law requires in homes with fuel-burning heat.

Do you offer furnace service in China, ME?
Yes. China is part of our Kennebec County service area, and J&R Mechanical Services handles furnace service for homes throughout the area. Call (207) 902-8899 or book online to schedule.
Is a heat pump better than a new furnace?
For many homes with ductwork, a ducted cold-climate heat pump can heat efficiently and adds air conditioning. Natural-gas customers often keep a furnace or pair one with a heat pump. We give you both options and the operating-cost comparison.
My furnace runs but blows cool air — what is wrong?
The usual causes are a dirty filter tripping the high-limit switch, a failed igniter or flame sensor, or a cracked heat exchanger. The last one is a safety issue: if you also smell exhaust or your CO detector sounds, shut the furnace down and call us.
