Heating System Repair in Glen Cove
50+ Years of Family-Owned Heating Repair Serving Nassau County
Glen Cove’s older homes run on hot water and steam heating systems that most contractors rarely see anymore. L. Graziose Plumbing Heating & Cooling has been repairing exactly these systems since 1973, serving Glen Cove and Nassau County from our base in Locust Valley, just minutes away on the North Shore. Three generations of the Graziose family, now led by brothers Robert and Michael alongside Daniel, stand behind every repair we complete.
We’re a licensed, insured plumbing and heating company, and that matters when a heating system repair turns up a related pipe issue: the same team handles both without a second contractor. Every job starts with an upfront estimate, and financing is available when a larger repair or replacement is the right call.
Heating failures don’t wait for business hours. Call us any time at (516) 614-4071 to schedule a repair or request emergency service for your Glen Cove home.
What Sets L. Graziose Plumbing Heating & Cooling Apart for Heating Repair
Our technicians treat your home with care: they arrive prepared, work cleanly, and leave your space the way they found it. That standard has held for over five decades, and it shows in what customers say. One described our team as “professional, on time, and incredibly thorough.” Another noted that we came out on Thanksgiving Day to restore heat to their home.
Multi-generational family ownership since 1973 means real accountability. There’s no franchise behind us, no call center routing your request. When you call, you reach a local team that has been serving North Shore Nassau County longer than many of Glen Cove’s current homeowners have lived there. And because we cover both heating equipment and plumbing under one roof, older homes with aging pipe connections don’t require separate service calls to address the full issue.
Heating System Repairs We Perform in Glen Cove
We repair heating systems across residential properties in Glen Cove and the surrounding Nassau County area. Our technicians are experienced with the full range of heating equipment found in local homes, from newer hydronic systems to decades-old steam setups that require a different diagnostic approach entirely.
Hot Water (Hydronic) Heating Systems
Hydronic heating systems circulate heated water through radiators or baseboard units. Common repair needs include circulator pump failure, zone valve malfunctions, pressure relief valve discharge, waterlogged expansion tanks, and aquastat or thermostat problems. These issues can produce no heat, uneven heat across zones, or visible water around the unit.
Steam Heating Systems
Steam systems are common in Glen Cove’s prewar and early postwar homes. Problems often stem from pressure imbalances, failed low-water cutoffs, leaking steam traps, and radiator air valve failure. Left unaddressed, these faults can produce banging pipes, cold radiators, or heat that only reaches part of the house.
Common Symptoms That Prompt a Repair Call
Recognizing early signs can help prevent a partial failure from becoming a full system shutdown:
- No heat or weak heat despite the thermostat being set correctly
- Uneven heating across rooms or zones in the home
- Banging, hissing, or kettling from pipes, radiators, or baseboard units
- Visible water or moisture near the heating unit, pipe joints, or radiator valves
- Frequent short-cycling where the system turns on and off without reaching the set temperature
- Rising energy bills without any change in usage or weather

Serving Glen Cove’s Homes Since the North Shore Was Being Built
Glen Cove’s housing stock is a textbook North Shore mix: prewar colonials, postwar Cape Cods, older multi-family buildings, and homes built long before current efficiency standards existed. Many rely on hot water or steam heating systems installed when the homes were new. We’ve been in business since 1973, the same era that shaped much of this neighborhood’s residential character, and our team has worked on these systems throughout Nassau County for over 50 years.
Homes near Hempstead Harbor and Long Island Sound face real wind exposure, which raises heating demand during winter months and puts added stress on systems already carrying their age. Freeze-thaw cycles and decades of use accelerate corrosion and wear on pipes and valves. These aren’t abstract concerns for us. We serve Glen Cove and the surrounding Nassau County communities, and we understand what local homes ask of their heating systems.
