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.
