Boiler & Furnace Heating System Repair and Replacement — Residential & Commercial
When the cold sets in across Rhode Island, a reliable heating system is not a luxury — it is a necessity. F.G. Lees & Sons provides expert boiler and furnace repair and full system replacement for both residential homeowners and commercial businesses throughout the state. Our technicians are experienced with all major makes and models, including steam boilers, hot water boilers, oil-fired furnaces, gas-fired furnaces, and combination units.
For homeowners, we offer fast-response emergency repairs during the heating season as well as planned off-season replacements that keep costs down and disruptions minimal. For commercial properties — including office buildings, multi-family housing, restaurants, and light industrial facilities — we understand that heating downtime means lost productivity and unhappy tenants or customers. Our crews work efficiently and professionally to restore heat as quickly as possible.
We also specialize in the installation of high-efficiency combination heating and cooling units (also known as dual-fuel or hybrid HVAC systems). These systems provide exceptional year-round comfort and energy savings, combining the power of a high-efficiency gas or oil furnace with a heat pump or central air system in a single integrated unit. If you are looking to modernize your Rhode Island property and reduce energy bills, ask us about a combination system evaluation.
Services include:
- Emergency boiler and furnace repair — 24 hours, 7 days/week
- Planned boiler and furnace replacement for homes and businesses
- High-efficiency boiler and furnace installations

Commercial Hot Water Mixing Valves & Pumps
F.G. Lees & Sons services commercial hot water mixing valves and circulation pumps for a wide range of Rhode Island businesses and institutions. Properly functioning mixing valves are essential for delivering water at safe, consistent temperatures — protecting occupants from scalding while also maintaining the high temperatures needed to prevent Legionella bacteria growth in large water systems.
We work with hotels, hospitals, schools, restaurants, apartment buildings, and other commercial properties to inspect, test, adjust, repair, and replace thermostatic mixing valves (TMVs), point-of-use mixing valves, master mixing valves, and commercial hot water circulation pumps. Keeping these components in top condition is not only a comfort and operational issue — it is a health and safety requirement in many Rhode Island commercial settings.
Commercial hot water services include:
- Thermostatic mixing valve (TMV) inspection, calibration, and replacement
- Master hot water mixing valve service for large commercial and institutional buildings
- Point-of-use mixing valve installation and repair
- Hot water circulation pump service, repair, and replacement
- Temperature testing and balancing for compliance with RI health and safety codes
- System assessment for multi-floor and multi-unit commercial properties
Plumbing Excavation Services — Sewer Lines, Water Lines & Drain Cleaning
F.G. Lees & Sons maintains its own excavation equipment, which means we handle underground plumbing work from start to finish — no subcontractors, no delays, no coordination headaches. Our plumbing excavation services address failing sewer lines, deteriorating water service lines, and clogged or collapsed underground drains across Rhode Island.
Underground drain cleaning is a seasonal service that we offer in spring, summer, and fall throughout Rhode Island. As the ground thaws in spring, debris, root intrusion, sediment, and winter damage often become apparent in underground drainage systems. Summer excavations take advantage of dry ground conditions for efficient, clean repairs. Fall services allow property owners to address issues identified during the year and prepare their systems for the stress of winter.
We use sewer camera equipment to diagnose the exact nature and location of underground problems before any digging begins, saving you time and money by avoiding unnecessary excavation. Our team has decades of experience navigating Rhode Island's mix of new and historic underground infrastructure — from modern PVC systems to aging clay tile and cast iron sewer lines found in Providence and other older communities.
Excavation and underground drainage services include:
- Sewer line repair and full replacement
- Water service line repair and replacement
- Underground drain cleaning (available spring, summer, and fall)
- Sewer camera inspection and pre-excavation diagnostics
- Root intrusion clearing and prevention
- Collapsed or cracked drain line repair
- Water drainage and grading solutions
- Trench excavation with licensed, insured operators and our own equipment
