Hear from Our Customers
You stop worrying about whether your AC will make it through summer. You stop hearing that rattling sound from the furnace at 2 a.m. Your energy bills drop because the system isn’t fighting itself to keep up.
That’s what proper HVAC work looks like. Not a temporary patch that buys you three months. Not a “let’s see if this holds” approach that leaves you guessing.
When your heating system maintenance is done right, your home stays comfortable without the constant adjustments. When your air conditioning repair is handled by someone who knows Long Island’s coastal humidity, the fix actually lasts. And when it’s time for HVAC replacement, you get a system sized correctly for your home—not whatever’s on the truck that day.
Most homeowners in Greenvale deal with the same problems: salt air that corrodes outdoor units faster than inland systems, humidity that makes even new systems work overtime, and older homes that weren’t built for modern HVAC loads. You need someone who understands those challenges, not just someone with a license and a ladder.
We’ve been handling heating and cooling across Nassau County for over 40 years. That means we’ve seen every type of system, every coastal corrosion issue, and every emergency that comes with living near the water.
Our technicians are licensed, certified, and experienced with the specific challenges Greenvale homeowners face. We’re not a national franchise following a script. We’re a local team that knows why your outdoor unit rusts faster here than it would 20 miles inland, and how to prevent it.
We handle furnace installation, air conditioning repair, indoor air quality improvements, and full HVAC replacement for residential properties throughout the area. When you call, you get a real person who can dispatch a technician—usually within two hours for emergencies.
First, you call or contact us with the problem. We ask a few questions to understand what’s happening—not to waste your time, but so we can send the right technician with the right parts.
For emergency repairs, we typically arrive within two hours across Nassau County. Our trucks stock common components for all major HVAC brands, which means about 70% of emergency calls get fixed the same day. No waiting a week for a part to ship.
For installations—whether it’s a new furnace, central air system, or ductless mini split—we start with a proper assessment of your home. That includes measuring your space, checking your existing ductwork if applicable, and accounting for things like insulation, sun exposure, and how coastal humidity affects your specific property. Then we provide a clear estimate that covers the equipment, installation, permits, and any modifications needed to do the job right.
Once you approve, we handle the permits, coordinate inspections, and complete the installation. You’re not managing five different contractors. One team handles it start to finish, and we don’t leave until the system is running correctly and you understand how to use it.

Our residential HVAC services cover everything from routine heating system maintenance to complete HVAC replacement. That includes air conditioning repair when your system stops cooling, furnace installation when your heating system finally gives out, and indoor air quality solutions when humidity or allergens become a problem.
For Greenvale specifically, we focus on systems designed for coastal conditions. That means corrosion-resistant materials for outdoor units, proper dehumidification to handle Long Island’s humidity swings, and sizing that accounts for the salt air and moisture load your system deals with year-round.
We also offer preventive maintenance agreements that catch small issues before they turn into expensive emergencies. Most HVAC failures happen because a minor problem—a dirty coil, a refrigerant leak, a failing capacitor—goes unnoticed until the system quits entirely. Regular maintenance costs a fraction of what you’d pay for an emergency repair or premature replacement.
All work includes proper permitting, manufacturer warranties on equipment, and our own guarantee on installation quality. Our technicians are EPA-certified for refrigerant handling and fully licensed to work on any residential HVAC system in New York State.
Most manufacturers recommend annual maintenance—once before heating season for your furnace or boiler, and once before cooling season for your air conditioner. That schedule makes sense for most Long Island homes.
But if you live close to the water, you might benefit from checking your outdoor AC unit twice a year. Salt air accelerates corrosion on coils and electrical connections, and catching that early can add years to your system’s life.
During a maintenance visit, we clean coils, check refrigerant levels, test electrical components, inspect ductwork for leaks, and verify that the system is running at the efficiency it’s supposed to. Most visits take about an hour, and they typically prevent the kind of failures that happen at the worst possible time—like a Saturday in July or a Sunday in January.
It depends entirely on what’s broken. A failed capacitor might cost a couple hundred dollars to replace. A refrigerant leak that requires finding the leak, repairing it, and recharging the system could run significantly more. A compressor failure on an older unit might mean it’s time to replace the whole system instead of sinking money into a repair that only buys you another year or two.
We provide upfront pricing before we do the work. If we find a problem during diagnosis, we explain what’s wrong, what it costs to fix, and whether repair makes sense given the age and condition of your system.
Sometimes the honest answer is that you’re better off replacing the unit than repairing it. We’ll tell you that. We’re not interested in selling you a repair today that turns into a replacement next month—that’s a waste of your money and our reputation.
Age is the biggest factor. Most residential HVAC systems last 15 to 20 years with proper maintenance. If your system is over 15 years old and needs a major repair—like a compressor, heat exchanger, or evaporator coil—replacement usually makes more financial sense.
You should also consider efficiency. Older systems use significantly more energy than newer models, especially if they’re running on R22 refrigerant, which is being phased out and expensive to refill. A new system might cost more upfront, but the energy savings often pay for a chunk of that over time.
Finally, if you’re repairing the same system multiple times a year, that’s a sign it’s on its last legs. At that point, you’re just paying for temporary fixes instead of investing in a reliable solution. We’ll walk you through the math so you can make an informed decision based on your specific situation.
Yes. We provide 24/7 emergency service throughout Nassau County and Long Island. When you call, you reach a real person who can dispatch a technician—not an answering service that takes a message and promises someone will call you back Monday.
For true emergencies, we typically arrive within two hours. Our trucks are stocked with common parts for all major HVAC brands, which means most emergency repairs get completed the same day without waiting for parts to be ordered and shipped.
We define an emergency as a system failure that affects your safety or comfort—no heat in winter, no cooling during a heat wave, or a system that’s creating a safety hazard. If it can wait until normal business hours, we’ll tell you that and schedule accordingly. But if you need help now, we’ll be there.
It depends on what problem you’re trying to solve. If humidity is the issue—and it often is on Long Island—a whole-home dehumidifier integrated with your HVAC system can make a huge difference. Coastal homes deal with moisture levels that make even new air conditioners struggle, and a dedicated dehumidifier takes that load off your cooling system.
If allergens or dust are the concern, we typically recommend upgrading to a high-efficiency filter or adding an air purifier to your system. Standard filters catch large particles, but they don’t do much for pollen, mold spores, or pet dander. A HEPA-rated filter or UV air purifier handles those.
For homes with poor ventilation—common in older construction—an energy recovery ventilator brings in fresh outdoor air without losing your heating or cooling. That’s especially useful if your home feels stuffy or if you notice condensation on windows during winter. We assess your specific situation and recommend what actually makes sense, not just what’s most expensive.
Most furnace installations take one to two days, depending on the complexity of the job. If we’re swapping out an old furnace for a new one in the same location with existing ductwork, that’s usually a one-day job.
If we’re upgrading to a higher-efficiency model that requires new venting, modifying ductwork, or relocating the unit, it might take two days. We handle all the permits and inspections as part of the installation, so you’re not coordinating that separately.
We don’t leave until the system is running correctly, the thermostat is programmed, and you understand how to operate everything. That includes explaining any new features, showing you where the filters are and how often to change them, and making sure you’re comfortable with the system before we pack up.
