Excellent Air Conditioning and Heating Service has been keeping Long Island homes warm for decades. We’re not a national franchise with rotating techs who don’t know the area. We’re local, family-owned, and we’ve seen every type of boiler system that exists in Nassau County.
Wantagh homes run on everything from old cast-iron units to modern condensing boilers. Our technicians are licensed, insured, and trained on all the major brands—Weil-McLain, Viessmann, Burnham, Navien, Bosch, Buderus. We know what breaks, why it breaks, and how to fix it without upselling you on stuff you don’t need.
You’re working with people who live here, understand how cold it gets, and know what it’s like when your heat goes out at 10 p.m. on a Tuesday.
You call or fill out a form. We answer—actually answer, not send you to voicemail. If it’s an emergency, we prioritize it and dispatch a tech to your home in Wantagh, NY as fast as possible. Most emergency calls get a response within one to two hours.
The technician shows up with a fully stocked truck. We run a full diagnostic on your boiler system—checking the burner, heat exchanger, circulator pump, pressure relief valve, thermostat connection, and anything else that could be causing the issue. Then we walk you through what we found, what needs to be fixed, and what it costs. No surprises.
If you approve the estimate, we get to work. Most boiler repair jobs finish the same day. Once it’s done, we test the system to make sure everything’s running right, clean up, and give you a receipt with warranty details. Then we leave, and your heat’s back on.

Boiler repair in Wantagh, NY covers anything that stops your system from heating your home. That includes ignition failures, pilot light issues, burner problems, pressure drops, leaks, strange noises, uneven heating, and error codes you can’t decode.
We handle gas boiler repair and hot water boiler systems. If your boiler’s cycling on and off, not reaching temperature, or leaking water around the base, those are all repairable issues. Same goes for circulation problems, thermostat malfunctions, and venting issues that trigger safety shutoffs.
Long Island winters are tough on boilers. Older systems in Wantagh often deal with sediment buildup, corroded pipes, and worn-out pumps. Modern condensing boilers can have issues with drainage, sensors, and electronic controls. Whatever the system, whatever the problem, we’ve fixed it before.
Every repair comes with a one-year warranty. If something we fixed breaks again within that window, we come back and make it right at no extra cost. You also get transparent pricing—no hidden fees, no inflated “emergency” charges, no pressure to replace your whole system unless it’s actually shot.
Most boiler repairs in Wantagh, NY run between $200 and $1,200, depending on what’s broken. A simple fix like a faulty thermostat or ignition sensor is on the lower end. Replacing a circulator pump, gas valve, or heat exchanger costs more because of parts and labor.
We give you a boiler repair estimate before we start any work. You’ll know exactly what it costs and what you’re paying for. There’s no markup on emergency calls, and we don’t charge extra just because it’s cold outside or after hours.
If your boiler is old and the repair costs more than half the price of a new system, we’ll tell you. Sometimes a repair makes sense. Sometimes it doesn’t. We’re not here to sell you something you don’t need—we’re here to give you the information so you can make the right call.
Most boiler repairs get done the same day, usually within two to four hours once the technician arrives. Simple fixes like resetting a pressure valve or replacing an ignition sensor take less than an hour. More involved repairs—swapping out a pump, fixing a leak, or replacing a control board—can take a few hours.
If we need to order a part that’s not on the truck, we’ll let you know upfront and get it as fast as possible. In most cases, we carry common parts for all the major boiler brands, so delays are rare.
Emergency calls in Wantagh, NY get prioritized. If your heat’s out and it’s freezing, we aim to have someone at your door within one to two hours. Once we’re there, we move fast. You’re not sitting in the cold waiting around for days.
The most common issue we see in Wantagh, NY is a boiler that won’t ignite or stay lit. That’s usually a pilot light problem, a faulty ignition sensor, or a gas valve issue. It’s fixable, and it doesn’t always mean your boiler is done.
Leaks are another big one. Water pooling around the base of your boiler can mean a cracked heat exchanger, a bad pressure relief valve, or corroded pipes. Some leaks are minor and cheap to fix. Others mean it’s time to replace the unit.
Low pressure, strange noises, and uneven heating are also common. Low pressure usually points to a leak or a problem with the expansion tank. Banging or whistling noises can mean sediment buildup or air in the lines. Uneven heating—where some rooms are warm and others aren’t—often comes down to circulation pump issues or zone valve failures.
If your boiler is under 15 years old and the repair costs less than half the price of a new system, repair it. If it’s over 20 years old, constantly breaking down, or the repair is expensive, replacement usually makes more sense.
Older boilers run at 70-80% efficiency. Modern condensing boilers hit 92-98%, which means lower fuel bills every month. If you’re spending $400 to $500 a year just keeping an old boiler limping along, a new system pays for itself in five to ten years through energy savings alone.
We’ll walk you through the math when we’re at your home in Wantagh, NY. If a repair buys you another five years, we’ll tell you. If you’re throwing money at a system that’s going to fail again in six months, we’ll tell you that too. No pressure, just honest advice based on what we see.
Yes. We’re available 24/7 for emergency boiler repair in Wantagh, NY. If your heat goes out in the middle of the night or on a weekend, you can call us and get a real person on the line.
Emergency calls get prioritized. We aim to have a licensed technician at your door within one to two hours, depending on where you are in Nassau County and what else is happening that day. Once we arrive, we move fast—diagnose the problem, explain what’s wrong, give you a price, and get your heat back on.
We don’t charge inflated rates for emergency service. You pay for the repair, not for the time of day. And if it’s something we can fix over the phone—like walking you through a reset or checking your thermostat settings—we’ll do that first before sending someone out.
Once a year, ideally in the fall before heating season starts. Annual boiler service catches small problems before they turn into expensive breakdowns in the middle of winter.
During a service call, a technician cleans the burner, checks the heat exchanger for cracks, tests the pressure relief valve, inspects the venting system, and makes sure all the safety controls are working. We also flush out sediment that builds up over time and reduces efficiency.
Regular maintenance extends the life of your boiler, keeps your energy bills lower, and reduces the chance of a no-heat emergency when it’s 20 degrees outside. Most boilers in Wantagh, NY last 15 to 30 years with proper care. Skip the annual service, and you’re looking at more frequent repairs and a shorter lifespan overall.
