We’ve spent over eight years handling HVAC services in Kenilworth, NY and across Nassau County. We’re not a national franchise with rotating technicians. We’re the same crew, working out of Lynbrook, serving the same neighborhoods year after year.

Our technicians are licensed, background-checked, and trained on the systems you actually have in your home. Central air, heat pumps, mini-splits, boilers—we work on all of it. We hold an A+ rating with the Better Business Bureau and a clean record with Nassau County Consumer Affairs because we show up when we say we will and charge what we quote.

Kenilworth homeowners deal with the same climate extremes as the rest of Nassau County. Summer temps hit the low 80s with humidity that makes it feel worse. Winter drops into the teens. Your system has to handle both, and when it doesn’t, you need someone who can diagnose the actual problem and fix it right the first time.

What We Actually Fix and Install

For heating maintenance in Kenilworth, NY, we inspect and tune up furnaces and boilers before winter hits. That means checking burners, testing safety controls, cleaning heat exchangers, and catching small problems before they turn into no-heat emergencies at 2 a.m. in January.

When your equipment is beyond repair, we handle furnace installation and AC replacement.

How much does it cost to replace an HVAC system in Kenilworth, NY?

The cost depends on the type of system, the size of your home, and whether you need ductwork modifications. A basic furnace and AC replacement for a 1,500-square-foot home typically runs between $8,000 and $15,000. That includes removing the old equipment, installing the new system, and making sure everything is sized correctly and up to code.

High-efficiency systems cost more upfront but lower your monthly energy bills. If your ductwork is leaking or poorly designed, fixing that adds to the cost but also improves comfort and efficiency. We don’t give ballpark quotes over the phone because every home is different. We assess your space, calculate the load requirements, and give you an accurate number before any work starts.

Financing options exist if you need them. But the real cost isn’t just the install price—it’s what you pay over the system’s 15-to-20-year lifespan in energy bills and repairs. A properly sized, well-installed system saves you money long-term.

Once a year, ideally in the fall before you need your heat. Annual maintenance catches problems early, keeps your system running efficiently, and extends its lifespan. Skipping it doesn’t save you money—it costs you more in higher energy bills and unexpected breakdowns.

During a maintenance visit, we inspect the heat exchanger for cracks, test the ignition system, check gas pressure, clean burners, and verify that safety controls work. For boilers, we check water pressure, inspect for leaks, test the circulator pump, and bleed radiators if needed. These aren’t optional tasks. A cracked heat exchanger can leak carbon monoxide. A failing ignition system leaves you without heat.

Nassau County winters aren’t forgiving. When your furnace quits in January, every HVAC contractor is booked solid with emergencies. Regular maintenance keeps you off that list. If your system is older or you’ve skipped maintenance for a few years, schedule it now before the cold hits.

Your AC blows warm air, won’t turn on, or runs constantly without cooling your home to the set temperature. You hear grinding, squealing, or banging noises. You notice water pooling around the indoor unit. Your energy bills spike without explanation. Any of these mean something’s wrong.

Warm air usually points to refrigerant leaks, compressor failure, or a broken reversing valve. Constant running without cooling suggests an undersized system, dirty coils, or low refrigerant. Strange noises often mean worn bearings, loose parts, or failing motors. Water leaks indicate clogged drain lines or frozen evaporator coils.

Don’t ignore these signs hoping they’ll resolve themselves. AC problems get worse, not better. A small refrigerant leak becomes a dead compressor. A dirty coil reduces efficiency and overworks the system. Catching issues early costs less than emergency repairs in the middle of summer when everyone else’s AC is also failing.

Most furnace installations take one to two days depending on the complexity. A straightforward replacement where we’re swapping an old furnace for a new one in the same location usually wraps up in a day. If we’re upgrading to a high-efficiency model that requires new venting, adding a humidifier, or modifying ductwork, it takes longer.

We start by removing your old furnace and inspecting the existing ductwork and venting. Then we install the new unit, connect it to your duct system, run new gas lines or electrical connections if needed, and install proper venting. After that, we test the system to make sure it heats evenly, cycles correctly, and meets safety standards.

You won’t be without heat for long. If we’re replacing a failed furnace in winter, we work fast to get your heat back on. We also pull the necessary permits and schedule inspections so everything is legal and up to code. Kenilworth homes vary in age and layout, so installation timelines depend on what we’re working with.

Not always, but sometimes it makes sense. If both units are over 15 years old, replacing them together saves you money on labor since we’re already there doing the work. It also ensures your indoor and outdoor units are matched for efficiency, which matters more with newer high-efficiency systems.

If your furnace is only five years old and your AC dies, replace just the AC. But if your furnace is 18 years old and limping along, consider replacing both. Older furnaces are less efficient and more likely to fail soon anyway. You’ll pay for another service call, more labor, and deal with another disruption.

Matched systems also perform better. A new high-efficiency AC paired with an old furnace won’t deliver the efficiency gains you’re paying for. The indoor coil and blower need to work together properly. Mismatched components reduce comfort and efficiency. We assess both units and give you an honest recommendation based on their age, condition, and your budget.

Boiler repair covers diagnosing and fixing issues that prevent your boiler from heating your home properly. That includes fixing leaks, replacing faulty circulator pumps, repairing or replacing pressure relief valves, addressing ignition problems, and fixing issues with the thermostat or zone valves.

We start by testing your boiler to identify the problem. Low pressure, no heat, strange noises, or error codes all point to specific issues. A leak might come from a corroded pipe, a bad valve, or a cracked heat exchanger. No heat could mean a failed ignition system, a tripped safety control, or a broken circulator pump.

Once we identify the cause, we explain what’s wrong and what it costs to fix. Some repairs are straightforward and inexpensive. Others, like a cracked heat exchanger, mean it’s time to replace the boiler. We don’t upsell replacements if a repair will get you through another few years. But if your boiler is 25 years old and needs a major repair, replacement often makes more financial sense than dumping money into an old system.
