About Reliable Boiler Service
Boiler Repair Company in Connecticut Near Me
Connecticut leans heavily on hydronic heat. A large share of homes still burn heating oil, and baseboard or cast iron radiators fed by a boiler are standard in the older housing stock that fills much of the state.
That mix keeps boiler repair busy: oil burner service, aging cast iron boilers with cracked sections, and a steady stream of oil to gas boiler conversion and condensing upgrades where gas mains reach. Energize Connecticut runs efficiency programs worth checking before you buy. Reliable Boiler Service connects Connecticut homeowners with technicians for boiler repair, boiler replacement and oil to gas conversion. Call (866) 456-6311.

Boiler Repair FAQs
Frequently asked questions about boiler repair
Common questions about boiler repair in Connecticut, answered plainly.
Talk to a real personIs a combi boiler a good fit for my home in Connecticut?
A combi suits homes with one or two bathrooms and a gas line big enough for its hot water demand. Larger households often do better with a heat-only boiler and an indirect tank.
Do condensing boilers work with old cast iron radiators?
They can, but they only condense when return water comes back cool. Outdoor reset control and properly sized radiators make the difference.
Why are my radiators cold at the top?
Air is trapped in them. Bleed each radiator with a radiator key until water runs steadily, then check the boiler pressure and top it up if needed.
My boiler is running but the house is cold. What should I check?
Look at the pressure gauge, listen for the circulator pump, and feel the pipes leaving the boiler. Hot boiler with cold pipes usually means a pump or zone valve problem.
Are there rebates for high-efficiency boilers?
Many gas utilities and state energy programs offer rebates on qualifying condensing boilers. Terms change often, so check your utility's current program before you buy.
