Signs Your Boiler Needs Replacing

Most boilers give plenty of warning before they fail completely. Knowing those signs means the difference between a planned replacement on your schedule and an emergency swap in January.

Warning Signs
  • System is 20+ years old — past average lifespan
  • Uneven heat — some radiators or zones not responding
  • Frequent repairs costing more than 50% of replacement value
  • Visible rust, corrosion, or leaking from the boiler body
  • Fuel bills rising despite normal usage
  • Pilot light failures, ignition problems, or lockouts

Call Us
How long does a boiler replacement take?
A standard residential boiler replacement takes one full day. Complex multi-zone systems or those requiring significant repiping may take two days. We'll tell you exactly what to expect before we start.
Can I convert from oil to gas during the replacement?
Yes — oil-to-gas conversions are a specialty of ours. We handle the new boiler, gas line connection (coordinated with your utility), updated venting, and all associated work. The fuel cost savings typically produce a strong payback.
What boiler brands do you install?
We primarily work with Weil-McLain, Peerless, Burnham, and Crown — proven, serviceable equipment backed by strong warranties. We'll recommend the right system for your specific load requirements.
Is it worth repairing or should I replace?
A good rule of thumb: if repair cost exceeds 50% of replacement cost and the system is over 15 years old, replacement wins economically. We'll give you the honest number — not the one that makes us more money.
Do you service all of Fairfield County and Westchester?
Yes. We serve Stamford, Greenwich, Darien, New Canaan, Norwalk, Westport, and all of Fairfield County CT, plus Rye, Port Chester, Mamaroneck, New Rochelle, and all of Westchester County NY.

Frequently asked questions

How much does a boiler replacement cost in Stamford, CT?

Cost depends on the boiler type (cast-iron or high-efficiency condensing), fuel (natural gas, oil or propane), required BTU output, venting and whether near-boiler piping, a new indirect water heater or oil-to-gas conversion work is included. Airmax provides a free written estimate after an on-site assessment — call (866) 203-0469. We do not publish flat pricing because sizing and piping drive the number.

Who installs boilers in Fairfield County, Connecticut?

Airmax Heating & A/C is a Connecticut-licensed heating contractor based in Stamford, CT (license HTG.0414617-D1) that installs and replaces boilers across Stamford, Norwalk, Greenwich, Darien, Westport, New Canaan and Fairfield, and in New Rochelle and Westchester County, NY.

How long does a boiler replacement take?

A straightforward like-for-like boiler swap is typically completed in one day. Jobs that add new venting, re-pipe the near-boiler manifold, convert fuel type or add an indirect water heater usually run two days. Airmax confirms the schedule in the written estimate before work starts.

Do you offer emergency boiler and no-heat service?

Yes. Airmax answers heating calls 24/7 at (866) 203-0469, including no-heat and failed-boiler calls in Stamford and the surrounding Fairfield County and Westchester towns.

Should I repair or replace my boiler?

Replacement is generally the better value when the heat exchanger is cracked or leaking, the unit is beyond its service life, parts are obsolete, or the repair approaches a large share of replacement cost. Airmax inspects the unit and gives you both options in writing rather than only a replacement quote.

What boiler brands does Airmax install?

Airmax installs and services standard residential gas, oil and propane boiler lines, and recommends equipment based on your fuel, venting and heat-loss requirements rather than a single brand. Ask for the specific model proposed on your estimate.

How do I get a boiler replacement estimate?

Call (866) 203-0469 or request a quote at https://getairmax.com/quote. Airmax schedules an on-site assessment, then sends one written estimate; payment on that estimate schedules the job.
