Furnace Repair for South Portland Homes
Common furnace problems include no heat, blower issues, ignition failures, strange noises, short-cycling, and thermostat malfunctions. Our technicians can quickly identify the root cause and get your heat back on.
How We Handle No-Heat Calls
No heat in cold weather cannot wait, and we prioritize it that way. Our trucks carry the parts that cause most winter failures — ignitors, flame sensors, blower motors, control boards, oil nozzles and filters — so the large majority of no-heat calls are diagnosed and fixed in one visit. You approve the exact repair price before we touch a part, and because our technicians are not on commission, the part we replace is the part that failed — nothing more. Regular annual maintenance is the best way to never need this page in the middle of winter.

Furnace Repair in South Portland, ME FAQs
Do you offer furnace repair in South Portland, ME?
Yes. South Portland is part of our Cumberland County service area, and J&R Mechanical Services handles furnace repair for homes throughout the area. Call (207) 902-8899 or book online to schedule.
Why does my furnace turn on and off every few minutes?
Short-cycling is most often a clogged filter causing overheating, a dirty flame sensor dropping the flame signal, or an oversized furnace reaching temperature too fast. It wastes fuel and wears components, so it is worth fixing promptly.
When is a furnace not worth repairing?
When it is well into its service life and facing a major repair like a heat exchanger, blower motor, or control board, replacement usually wins the math — especially counting the fuel savings of a modern high-efficiency unit. A cracked heat exchanger on an older furnace is almost always a replacement, for safety reasons.
