Rhode Island Heating Services — Boilers, Furnaces, and Emergency Repair Since 1889
F.G. Lees & Son is a licensed plumbing and heating contractor, which means one call handles your boiler, your furnace, or your heating distribution system — without searching for a second company.
In a New England Winter, a Heating Failure Is an Emergency
Rhode Island winters are not forgiving. When a heating system fails on the coldest night of the year, pipes can begin freezing within hours — and the difference between a repair call and a catastrophic loss is often how fast a licensed contractor arrives. We've maintained and repaired heating systems across Rhode Island through 135 consecutive New England winters. Emergency heating service is available 24 hours a day, 365 days a year, with same-night dispatch when you need it most.
Gas, oil, or electric. Forced air, hot water baseboard, or steam. Whatever system is in your home or building, our team is equipped to diagnose and service it. Most Rhode Island homeowners aren't aware that a licensed plumber and heating contractor can service their boiler — and many heating-only companies aren't equipped to handle the plumbing side of a hydronic heating system. We hold both licenses, which means we cover both sides of the work.

Our Heating Services
Boiler Services
From annual tune-ups to emergency no-heat calls, we service steam boilers, hot water boilers, and high-efficiency condensing units. We are Navien-certified — a factory-specific credential that most Rhode Island plumbing and HVAC companies do not hold — and we service all fuel types and boiler configurations across residential and commercial properties.
Furnace Services
Forced air systems require a different diagnostic approach than hydronic heating — and our team services both. Whether your furnace is failing to ignite, cycling incorrectly, or simply due for an inspection before the season turns, we provide thorough diagnosis before recommending any repair or replacement.
Oil-to-Gas Conversions
Converting from oil to gas is one of the highest-return heating upgrades available to Rhode Island homeowners — but the work involves both fuel system removal and new equipment installation. Because we hold plumbing and heating licenses under one contractor, we handle the full conversion without coordinating between trades.
We Diagnose Before We Recommend
If your heating bills are climbing or your system is behaving inconsistently, the right first step is a diagnostic visit — not a quote for a new system. Our technicians test efficiency and inspect components before any work is proposed. Sometimes the answer is a tune-up. Sometimes it's a specific repair. Occasionally it's a replacement. You'll know which before you spend anything.
Frequently Asked Questions About Heating Services in Rhode Island
Can a plumber service my boiler or do I need an HVAC company?
In Rhode Island, licensed plumbing contractors are authorized to service boilers and hydronic heating systems. F.G. Lees holds both plumbing and heating contractor licenses, so boilers, furnaces, and all associated distribution systems are covered under one call. You do not need a separate HVAC company for boiler work.
Do you offer emergency heating repair outside of business hours?
Yes. Our emergency line is answered 24 hours a day, 7 days a week, including nights, weekends, and holidays. After business hours, calls forward to on-call staff. Heating failures happen when systems are under the most load — which is almost always during the coldest stretches of the year, often overnight.
What heating systems do you service?
We service gas, oil, and electric heating systems across all major configurations — steam boilers, hot water boilers, forced air furnaces, and baseboard systems. We are also Navien-certified for high-efficiency condensing boiler service, which requires factory-specific training beyond a standard heating license.
How do I know if my heating system needs a repair or a full replacement?
That determination starts with a diagnostic visit, not an estimate. We test system efficiency and inspect components before recommending any course of action. Many systems that appear to be failing have a specific, repairable cause. We'll tell you what we find and what we recommend before any work begins.
Do you service heating systems in commercial buildings?
Yes. Our commercial division services heating systems in high-rise buildings, hotels, hospitals, and condominium complexes across Rhode Island. For large-scale commercial mechanical needs, see our commercial services page.
