Boiler Repair, Service & Installation in Rhode Island — Every System Type, Including Navien
Rhode Island homes and commercial properties run on some of the oldest and most varied heating systems in the country — and since 1889, F.G. Lees & Son has serviced every one of them, from century-old steam boilers in Providence triple-deckers to the latest Navien high-efficiency condensing systems that most local plumbers are not trained to touch.
When your boiler acts up — or stops working entirely — the right diagnosis matters as much as the repair. We identify the actual cause before recommending any work, which means you never pay for parts a system doesn't need. Whether you're hearing a strange noise at midnight, preparing for a tune-up before winter, or weighing repair against replacement on an aging unit, we'll give you a straight answer and get the work done right.
Boiler Service for Every System Type
Rhode Island heating systems aren't one-size-fits-all, and neither is our service. We work on steam, hot water, electric, and high-efficiency boilers — and we understand that the failure symptoms, diagnostic approach, and repair method differ significantly between them.
Steam Boilers
Steam boilers are common in older Rhode Island homes and multi-family buildings, and they require a technician who understands how a steam system actually behaves — not just how to swap parts. Banging pipes (a condition called water hammer), uneven heat between radiators, a system that short-cycles, or a pressure gauge reading outside normal range are all symptoms with distinct causes that a proper diagnosis will separate. We service and repair all steam boiler makes and models, including low-pressure residential systems and larger commercial steam plants.
Hot Water (Hydronic) Boilers
Hot water boiler service in Providence and across Rhode Island is one of our most common residential and commercial calls. Hydronic systems that are losing pressure, failing to circulate heat evenly, producing discolored water, or running the circulation pump continuously all point to specific mechanical issues — expansion tank failure, air in the system, a failing circulator, or a pressure relief valve that's weeping. We diagnose and repair the actual problem rather than defaulting to a full system replacement.
High-Efficiency & Navien Boilers
Navien high-efficiency condensing boilers require factory-specific training to service correctly — and F.G. Lees technicians hold that certification. This is not a credential most Rhode Island plumbers or HVAC companies carry. If you have a Navien system and have struggled to find a qualified local technician, we are the answer. Beyond Navien, we service all high-efficiency boiler brands. Common issues with condensing systems — error codes, condensate drain blockages, heat exchanger fouling, ignition failures — are within our routine scope of work.
What an Annual Boiler Tune-Up Actually Includes
A boiler tune-up is not a visual inspection and a filter swap. A proper annual service visit covers the components that determine whether your system runs safely and efficiently through the heating season — and skipping it is how a minor issue becomes an emergency repair in February.
A tune-up from F.G. Lees includes:
- Combustion analysis to verify fuel-to-air ratio and confirm efficient, clean burn
- Pressure and temperature relief valve inspection and test
- Burner cleaning and inspection for wear, corrosion, or fouling
- Flue and venting inspection to confirm safe exhaust routing
- Circulation pump test and bearing check on hydronic systems
- System pressure check and expansion tank evaluation
- Controls and safety device verification
- Visual inspection of all accessible piping, valves, and connections
A boiler running outside its optimal combustion range costs more to operate every month and shortens the system's lifespan. A failed pressure relief valve is a safety hazard. An uninspected flue is a carbon monoxide risk. The tune-up is what keeps those risks from becoming emergencies.
Honest Repair vs. Replacement Guidance
Not every aging boiler needs to be replaced. We've kept well-maintained systems running reliably well past the 20-year mark, and we've also seen newer boilers that were so poorly installed or neglected that repair no longer made financial sense. Our technicians give you an honest assessment of where your system stands — what it needs, what it would cost, and whether repair or replacement is the smarter investment given the system's age, condition, and efficiency.
Replacement is the right call when a system is unsafe, when repair costs are approaching the cost of a new installation, or when efficiency losses are driving up fuel bills enough to make a new high-efficiency unit pay for itself within a reasonable timeframe. We'll walk you through the numbers and let you make an informed decision.
Frequently Asked Questions About Boiler Service
What's that banging noise coming from my boiler or pipes?
The answer depends on your system type. In a steam system, banging is almost always water hammer — condensed water trapped in a steam line getting hit by live steam. In a hot water system, banging or kettling usually points to scale buildup on the heat exchanger or a circulation problem. Both are diagnosable and fixable, but the cause needs to be confirmed before any repair is made.How long should a boiler last?
A well-maintained boiler typically lasts 20 to 30 years, and some cast iron steam boilers in Rhode Island have been running reliably for considerably longer. Annual tune-ups, prompt attention to minor issues, and proper water treatment are the primary factors that determine how long a system lasts. Neglect shortens that window significantly.What's the difference between a boiler tune-up and a boiler repair?
A tune-up is scheduled preventive maintenance — cleaning, testing, and adjusting a system that is operating but needs to be verified for the season ahead. A repair addresses a specific failure or symptom that has already developed. Many repairs we see in December and January could have been caught and resolved at a tune-up in October.I have a Navien boiler. Can you service it?
Yes. F.G. Lees technicians are Navien-certified, which means we've completed the factory-specific training Navien requires for authorized service. Most Rhode Island plumbers and HVAC companies do not hold this certification. If you've been told your system requires a Navien-authorized technician and haven't been able to find one locally, call us.My boiler is more than 20 years old. Should I replace it now or wait?
Age alone isn't the deciding factor — condition, efficiency, and repair history are. We'll assess your system honestly and give you a clear picture of what it would cost to keep it running well versus what a replacement would cost and save. If repair still makes sense, we'll tell you. We recommend replacement only when it genuinely is the better financial and safety decision.
