You’re not dealing with a broken boiler because it’s convenient. It’s cold, your family needs heat, and you need someone who can diagnose the problem correctly the first time.
That’s what matters. Not whether the circulator pump failed or a zone valve stuck—you just want your house warm again without paying for guesswork or unnecessary parts.
When we show up for residential boiler repair in Glenwood Landing, NY, we’re looking at the whole system. Water pressure, flame sensor, expansion tank, thermostat communication. We find what’s actually wrong, explain it in plain terms, and fix it with parts that last. You’re not getting a sales pitch for a new boiler unless yours is truly done—and even then, we’ll walk you through why.
Most repairs get handled same day. You’re back to normal heat, and your system’s running the way it should.
Excellent Air Conditioning and Heating Service has been fixing boilers in Glenwood Landing, NY and across Nassau County for over 30 years. We’re a family-operated company, which means you’re not getting a different crew every time or a call center when you need help.
Our technicians are licensed, insured, and trained on gas boiler repair, oil systems, and hot water boilers. They know how coastal conditions affect equipment here—salt air, humidity, and the temperature swings that stress older systems.
We’ve seen what breaks, what lasts, and what homeowners in this area actually need. That experience shows up in how we diagnose problems, communicate options, and stand behind the work.
You call, we listen to what’s happening, and we schedule a visit—same day in most cases. If it’s an emergency and you’re without heat in the middle of winter, we prioritize it.
When we arrive, the technician runs a full diagnostic. That means checking burner operation, inspecting the heat exchanger, testing safety controls, and looking at water flow and pressure. We’re not guessing. We’re identifying the actual failure point.
Once we know what’s wrong, we explain it. You’ll hear what failed, why it matters, and what it costs to fix. If we need a part, we’ll tell you the timeline. Most common repairs—igniters, pumps, thermocouples—we handle on the spot.
After the repair, we test the system under normal operating conditions. You’ll have heat, and you’ll know the boiler’s running safely. We don’t leave until it’s working right.

Every service call starts with a system evaluation. We’re checking ignition, combustion, venting, and water circulation. For gas boiler repair in Glenwood Landing, NY, that includes inspecting the gas valve, flame sensor, and pressure switches.
If you’ve got a hot water boiler, we’re also looking at the circulator pump, zone valves, and expansion tank. Steam systems get checked for water level controls, pressure relief valves, and steam traps. Each type has its own failure points, and we know what to look for.
Repairs are done with quality parts that match your system. You’re not getting the cheapest components that’ll fail again in six months. We’re fixing it right so you’re not calling us back next week with the same issue.
Nassau County winters are tough on heating equipment, and Glenwood Landing’s coastal location adds salt air corrosion into the mix. We account for that. If your system’s been affected by local conditions, we’ll point it out and recommend what actually helps—not what makes us the most money.
Most boiler repairs in Glenwood Landing, NY run between $200 and $1,000 depending on what’s broken. A simple fix like replacing an igniter or resetting a safety control sits on the lower end. Replacing a circulator pump, gas valve, or repairing a leaking heat exchanger costs more.
We give you upfront pricing before we start the work. You’ll know what the repair costs, what the part is, and why it’s necessary. If it’s an emergency call during off-hours, there’s an additional service fee—but we’re clear about that when you call.
The biggest cost variable is whether we’re fixing something or replacing it. If a component can be repaired and will hold up, that’s what we recommend. If it’s going to fail again soon, we’ll tell you that too and explain your options.
Ignition failures top the list. Pilot lights go out, igniters crack, and flame sensors get dirty. When your boiler won’t fire up, it’s usually one of those three.
Circulator pump failures are common too, especially in older systems. The pump moves hot water through your baseboards or radiators. When it quits, the boiler runs but you don’t get heat in the house. You’ll hear the boiler fire, but the rooms stay cold.
We also see a lot of pressure issues—either too much or too little. Low water pressure keeps the boiler from firing. High pressure can trip safety valves and cause leaks. Both are usually tied to the expansion tank or a faulty pressure relief valve. Coastal conditions here in Glenwood Landing accelerate corrosion on tanks and valves, so these components wear faster than they would inland.
Yes. Most service calls get scheduled same day, and we handle a lot of repairs on the first visit. If you call in the morning, there’s a good chance we’re at your house that afternoon.
Emergency calls get prioritized. If your heat’s out and it’s 20 degrees outside, we’re not making you wait three days. We’ll get someone there as fast as we can—often within a few hours.
The only time same-day service gets tricky is during the first cold snap of the season. Everyone’s boiler decides to quit at once, and call volume spikes. Even then, we do everything we can to get to you quickly. If we can’t make it same day, we’ll tell you exactly when we can be there and what you can do in the meantime to stay safe and warm.
If your boiler is under 15 years old and the repair costs less than a third of a new system, fix it. You’ll get several more years out of it, and the repair pays for itself in avoided replacement costs.
If your boiler is over 20 years old, breaking down frequently, or needs a major repair like a new heat exchanger, replacement makes more sense. Older boilers run at 60-70% efficiency. New ones hit 95% or higher. That efficiency difference cuts your heating bills noticeably, especially with energy costs climbing in Nassau County.
We’ll walk you through the math. You’ll see what the repair costs, what a new system costs, and what you’d save on energy over the next few years. Then you decide. We’re not pushing you toward a sale if a repair gets you through another five winters without trouble.
Most repairs take one to three hours. Replacing an igniter, thermocouple, or flame sensor is usually done in under an hour. Swapping a circulator pump or zone valve takes closer to two hours. More involved work—like addressing a venting issue or replacing a gas valve—can stretch to three or four hours.
If we need to order a part, that adds time. Common components we stock on the truck. Specialty parts for older or less common boilers might take a day or two to get. We’ll tell you the timeline upfront so you know what to expect.
The diagnostic itself takes 30 to 45 minutes. We’re not rushing through it. A thorough inspection catches the real problem and prevents a callback because we missed something. Once we know what’s wrong and you approve the work, the actual repair moves quickly.
Yes. We work on gas boilers, oil boilers, hot water systems, and steam boilers. Each type has different components and failure points, and our technicians are trained on all of them.
Gas boiler repair in Glenwood Landing, NY is the most common call we get, but we handle plenty of oil systems too—especially in older homes. Steam boilers are less common now, but we still service them and know how to maintain the specific controls and safety devices they require.
If you’ve got a high-efficiency condensing boiler, we work on those as well. They’re more complex than standard boilers and require different diagnostic tools, but we’ve got the equipment and experience to service them correctly. Whatever you’re running for heat, we can fix it.
