A lot of homeowners in Bellmore, Merrick, Wantagh, and Massapequa call us after noticing small issues for weeks before the system suddenly stops working completely.
Water Heater Not Getting Hot
One of the most common calls we get is: “My water heater stopped getting hot.”
For gas water heaters, the issue could involve pilot lights, thermocouples, igniters, or gas control valves. For electric systems, we often find failed heating elements, thermostat problems, or electrical issues.
Our technicians will test the system, explain what failed, and give you clear repair options.
Water Heater Leaking From Bottom
A leaking water heater can mean very different things depending on where the leak is coming from.
Sometimes it’s a loose fitting, expansion tank issue, relief valve, or drain valve. Other times, the tank itself has started failing internally.
If the tank is cracked or heavily rusted, a water heater replacement may be the safer option. But many leaks can still be repaired if caught early enough.
Water Heater Making Loud Noises
If your water heater sounds like it’s banging, popping, or rumbling, there’s usually sediment buildup inside the tank.
This is extremely common on Long Island because of mineral buildup in the water over time. Sediment buildup can reduce efficiency, damage heating components, shorten the life of the system, and increase energy bills.
In many cases, flushing the tank or repairing damaged components can solve the problem.
Tankless Water Heater Repair
Tankless systems are great when they’re working properly, but they require proper maintenance and specialized diagnostics.
We repair Navien tankless systems, Rinnai tankless systems, Bosch tankless units, Rheem tankless water heaters, AO Smith tankless systems, and other major brands.
Common tankless water heater problems include ignition failures, scale buildup, fluctuating temperatures, blocked vents, error codes, and low flow issues.
If your tankless system keeps shutting off or isn’t producing enough hot water, we can diagnose the issue and recommend the best solution. If needed we also do tankless water heater installations.
Emergency Water Heater Repair
A leaking or failed water heater can become a serious problem fast. If water is pooling around the tank, your system is not producing hot water, or you’re worried about damage to your home, call AJ Services Plumbing and Heating right away.
We help with urgent water heater issues across Long Island, including leaking tanks, no hot water, failed gas water heaters, tankless error codes, and water heater problems that need same-day attention.
Should You Repair or Replace Your Water Heater?
A lot of homeowners ask us this question. The answer usually depends on the age of the unit, the condition of the tank, repair history, efficiency, and cost of repair.
If the unit is relatively new and the issue is isolated, repair often makes sense. If the tank is heavily corroded, leaking internally, or nearing the end of its lifespan, replacement may save money long term.
We’ll explain both options honestly so you can make the right decision for your home and budget.
Common Water Heater Problems We See on Long Island
Over the years, we’ve noticed some recurring issues in Nassau and Suffolk County homes.
Older homes often deal with aging gas water heaters, sediment-heavy tanks, corroded shutoff valves, outdated venting, and undersized systems.
During colder months, we also see frozen lines, venting issues, increased strain on older systems, and delayed recovery times.
A lot of homeowners don’t realize their water heater has been slowly failing until they suddenly run out of hot water during a busy morning.
