  • Visible rust, leaks, or damaged parts
  • Noisy operation or banging pipes
  • You’re planning a home renovation or energy upgrade

Benefits of upgrading:



  • Lower fuel usage and energy bills
  • Consistent, even heating across all zones
  • Compact, wall-mounted options available
  • Reduced carbon emissions
  • Compatibility with smart thermostats


We install high-performance boilers from trusted brands — and we’ll walk you through rebates or incentives available for energy-efficient upgrades in New York.

FAQs About Boiler Systems

  • How long does a boiler last?

    Most boilers last 15 to 30 years depending on the type, usage, and maintenance. If yours is over 20 years old, it may be time to consider a replacement.

  • What’s better: boiler or furnace?

    Boilers offer radiant, even heat and are ideal for homes with radiators or radiant floors. Furnaces are better for homes with ductwork and central air. We can help you determine the best option for your setup.

  • Do you service oil boilers?

    Yes. We service and install both gas and oil boilers, including older systems and modern, high-efficiency models.

  • How soon can you replace a broken boiler?

    In emergency situations, we can often replace a boiler within 24–48 hours, depending on availability. We prioritize restoring heat quickly.
