How a Boiler Works

- Circulator pump — pushes hot water through the loop
- Expansion tank — absorbs pressure as water heats and expands
- Baseboard loop — hot water out, cooler water returns

Boiler Service in Portland, ME FAQs
Do you offer boiler service in Portland, ME?
Yes. Portland is part of our Cumberland County service area, and J&R Mechanical Services handles boiler service for homes throughout the area. Call (207) 902-8899 or book online to schedule.
How long does a boiler last?
Cast-iron oil and gas boilers commonly run 25–30 years with annual cleaning; high-efficiency condensing boilers average 15–20. Age alone is not a reason to replace — falling efficiency, rust at the sections, or repeat no-heat calls are.
What drives the cost of a new boiler?
Fuel type, efficiency tier, venting requirements, and whether an indirect water heater is added all move the price. Call for a firm quote based on your specific system.
