How long does a boiler last?

A well-maintained boiler typically lasts 20-30 years — and cast-iron boilers often go longer. Annual maintenance is the biggest factor in extending its life.

Hot-water vs. steam boiler — what's the difference?

Hot-water boilers circulate heated water through baseboards or radiators. Steam boilers boil water and send steam through pipes to steam radiators. Both work well; the right one depends on your existing distribution system.

Should I upgrade my old boiler to a high-efficiency model?

Age, repair history, comfort, measured condition, and operating efficiency all matter. We compare the existing boiler with appropriately sized replacement options so you can weigh reliability, fuel use, and long-term ownership value.

Do you repair boilers on weekends?

Maintenance-plan members can request 24/7 emergency boiler service, including weekends. Non-plan customers can request service during normal business hours.

Why boilers are a great fit for CT homes

Boilers transfer heat through water rather than forced air, which delivers a steady, comfortable warmth without the dust circulation or temperature swings of furnaces. They also pair beautifully with radiant floor heat — a luxury feature that's increasingly common in renovations.

When to consider replacement

If your boiler is over 20 years old, your fuel bills keep climbing, or you've had two or more major repairs in the last two years, it's worth getting a quote on a replacement. Modern high-efficiency boilers can deliver dramatically lower operating costs — and we'll lay out the options honestly so you can decide what makes sense.
