Boiler Replacement in Vermont

When a boiler reaches the end of its life in Vermont, timing matters. A mid-January failure with temperatures at 10°F is not when you want to be comparing quotes from multiple contractors. At Langlois Plumbing, Heating & AC, we keep our schedule available for same-day boiler replacement assessments and can typically install replacement equipment within two to three business days of assessment – faster for urgent situations.
I’ve replaced boilers in Vermont homes that had been running on borrowed time for years. The homeowner often knows something is wrong – the boiler runs constantly, the heating bills keep climbing, the system makes noises it didn’t used to make. If your boiler is 20-plus years old, a replacement assessment is worth scheduling before the heating season, not after a failure.

A residential boiler in Vermont typically shows signs of failure between 20–30 years of age, though efficiency loss begins around year 15. Warning signs requiring immediate replacement assessment include repeated no-heat calls, flue gas spillage, heat exchanger cracks, or an AFUE rating below 70%. Most residential boiler replacements in Vermont are completed in one day.

Signs Your Boiler Needs Replacement

A boiler that requires frequent service calls, fails to maintain temperature, produces unusual odors, shows rust or corrosion on the heat exchanger, or has an AFUE rating below 70% is a replacement candidate. We give you an honest assessment – if repair is the right answer, we’ll say so. We don’t push replacement when a repair will extend the life of a functional system.

What to Expect During Boiler Replacement

We begin with a heat load calculation to right-size the new equipment. Oversized boilers short-cycle and wear out faster – correct sizing matters for both efficiency and longevity. After sizing, we present equipment options with pricing. Installation is typically completed in six to eight hours. We haul away the old unit and leave the mechanical room clean.

Frequently Asked Questions

Age, repair history, and efficiency are the three factors. A boiler over 20 years old that has required two or
more service calls in the past two seasons is generally a replacement candidate. A newer boiler with an
isolated component failure is usually a repair. We'll give you a straight answer during the assessment.

In most cases, yes. We assess the existing distribution system during the replacement evaluation and identify any components that need attention. Most Vermont homes with hot water baseboard or cast-iron radiators can accept a modern boiler without significant additional work.
