Baseboard heating is one of the most common heating systems found in Nassau County homes. From Bellmore and Wantagh to Massapequa, Merrick, and surrounding Long Island communities, many homes built throughout the 1950s–1990s still rely on hot water baseboard systems for dependable heat.
When these systems begin having issues, the signs are often subtle. One room may stay colder than the rest of the house. A heating zone may stop responding. You may hear ticking pipes, notice uneven temperatures, or realize your boiler seems to run constantly without keeping up.
AJ Services has spent more than 20 years diagnosing and repairing baseboard heating systems throughout Nassau County. Whether it’s trapped air, a failed zone valve, circulation problems, or a larger boiler repair issue, we’ll identify the cause and fix it correctly.
This does a few things better:
The most common issue we see is trapped air in the system.
Air often enters the pipes during the summer when heating systems sit unused. When colder weather returns, that trapped air can block circulation, preventing hot water from reaching the baseboard units.
Bleeding the zone often solves the issue quickly, but it’s only one of many problems we repair.
Nassau County has more hot water baseboard systems than many other parts of the country. During Long Island’s post-war housing boom in the 1950s and 1960s, these systems were installed in thousands of homes, and many still rely on them today.
Our technicians understand what these systems look like after decades of use. We know common failure points, corrosion patterns, and how to properly bleed and balance multi-zone systems.
If another company repaired your heating system and the problem returned, we’ll identify what was missed.
Helpful Tip: Keep furniture, curtains, and rugs away from baseboard units. Blocking airflow can reduce heating performance and make your boiler work harder than necessary.
Sometimes what appears to be a baseboard issue is actually a boiler or controls problem.
Common causes include:
We trace problems back to the source instead of treating symptoms. That’s how you get a repair that lasts.
AJ Services repairs all parts of hydronic heating systems, including boilers, circulator pumps, expansion tanks, thermostats, zone valves, and baseboard units. We can install a new boiler too.
Many Nassau County homes still have original baseboard components from the 1960s and 1970s.
Some still perform well. Others develop corroded fins, scale buildup, or leaks that reduce efficiency and comfort.
We’ll give you an honest recommendation. If replacing a few sections solves the problem, we’ll tell you. If replacement makes more financial sense, we’ll explain that too.
No pressure. Just straightforward advice.
The most common causes are failed zone valves, trapped air, or thermostat wiring issues. We can identify the cause during the first visit.
Banging or ticking usually comes from trapped air or expansion in older copper lines. Persistent noise can indicate water hammer or expansion tank problems.
Many repairs are completed in a single visit. Larger balancing or multi-zone issues can require additional time.
