Service & repair — oil and gas

We service oil burners, oil boilers and gas boilers: annual tune-ups and cleanings, no-heat calls and repairs. Send a request and the office will call you to schedule based on technician availability.

No heat? Call 631-264-8800 — anytime — or see emergency help.

⭐ Service contract: why have one

  • A yearly tune-up and cleaning keeps your boiler or furnace running well
  • Covered repairs are included (we give you the coverage list)
  • Priority on no-heat calls when it's busy

When it's busy (cold snaps, storms), phone calls get priority over web requests, and customers with a service contract or on automatic delivery are served first. Everyone else is helped as quickly as we can after that. To be first in line, ask about a service contract or automatic delivery.
