Hear from Our Customers
You get your house back to a comfortable temperature without waiting days for an appointment. When your air conditioning stops working during a Long Island summer, high humidity and rising indoor temps disrupt everything—sleep, work, your kids’ routines. Same goes for winter heating failures.
We stock parts on our trucks, so about 70% of emergency calls get handled same-day. No waiting for orders. No callbacks about “parts arriving next Tuesday.” You call, we come out, we diagnose the problem, and we fix it if you approve the work.
Our team has been doing this for over 40 years. We’ve seen every brand, every breakdown, every weird noise your system can make. That experience means faster diagnosis, honest recommendations about whether you need a repair or a full replacement, and straight answers about what things actually cost. You’re not getting upsold on a new system when a $200 repair would buy you another three years.
We’ve been handling complex HVAC and refrigeration work since the 1980s. We built our reputation on commercial and marine systems—airports, restaurants, boats—the kind of work where failure isn’t an option and shortcuts get exposed fast.
Now we’re bringing that same level of expertise to residential heating and cooling in New Cassel and throughout Nassau County. You’re dealing with a team that’s solved problems most residential-only companies have never seen. We’re licensed, insured, and we’ve earned dozens of five-star reviews by showing up when we say we will and doing the work right the first time.
New Cassel has around 3,200 households, and we understand what homeowners here are dealing with—aging systems, tight budgets, and the need for someone who won’t take advantage when your AC dies on the hottest day of the year.
First, you call or contact us and describe what’s happening. No heat, no cool air, strange smells, water leaking—whatever it is. We schedule a time that works for you, often same-day if it’s an emergency.
When we arrive, we diagnose the problem. That means actually testing components, checking airflow, measuring refrigerant levels—not just guessing. Once we know what’s wrong, we explain it in plain language and give you an upfront price before we touch anything. No surprise charges, no “we found three more problems” upsells unless something genuinely needs attention for safety.
If you approve the work, we handle it right there in most cases. Our trucks carry common parts for all major brands. If it’s a bigger job—like a full furnace installation or HVAC replacement—we walk you through timing, equipment options, and what makes sense for your home and budget. You get a free estimate, and we don’t start until you’re clear on everything.
After the work’s done, we test the system, clean up, and make sure you understand how to maintain it. If you have questions later, you call the same number and talk to the same team.

We cover the full range of residential HVAC work. Air conditioning repair when your system stops cooling or starts leaking. Furnace installation and heating system maintenance before winter hits. Indoor air quality services if you’re dealing with dust, odors, or allergens that won’t go away. HVAC replacement when your 20-year-old system finally gives up.
Nassau County homeowners spend over $10 billion annually on HVAC services nationally, and a big chunk of that goes to emergency repairs that could’ve been prevented with basic maintenance. We offer preventive maintenance programs that catch small problems before they turn into expensive breakdowns. A well-maintained system lasts 15 to 20 years and can save you up to 20% on energy bills compared to a neglected one.
Long Island’s climate—hot, humid summers and cold winters—puts serious stress on HVAC systems. Your equipment works harder here than it would in milder areas. That’s why regular tune-ups matter, and why choosing someone with deep technical knowledge makes a difference. We service all major brands and handle both simple fixes and complex custom solutions that most residential-only contractors can’t touch.
If your energy bills suddenly spike without explanation, that’s usually your system struggling. If you’ve got hot and cold spots in different rooms, that’s a distribution problem. If you’re smelling something musty or burning, that’s a safety issue. All of these are things we diagnose and fix regularly.
It depends entirely on what’s broken. A simple fix like a clogged drain line or a tripped breaker costs under $200. A failed capacitor or contactor runs $150 to $400. If your compressor died or you’ve got a refrigerant leak that requires major repairs, you’re looking at $1,000 to $3,000—and at that point, we’ll have an honest conversation about whether replacement makes more sense.
We’ve seen homeowners get quoted $10,000+ for “compressor problems” that turned out to be a $300 part. That’s why we give you a free estimate with a clear breakdown before any work starts. You’ll know exactly what’s wrong, what it costs to fix, and whether you’re better off repairing or replacing based on your system’s age and condition.
Most emergency AC repairs we handle fall in the $300 to $800 range. If it’s more than that, we’ll explain why and give you options.
A straightforward furnace replacement usually takes one full day, sometimes stretching into a second day depending on your home’s setup. If we’re swapping out an old furnace for a new one in the same spot with similar ductwork, that’s typically a one-day job.
If your ductwork needs modification, if we’re relocating the unit, or if there are code updates required for your specific installation, it might take two days. We’ll tell you the timeline upfront during the estimate so you can plan accordingly.
The actual work involves removing your old system, making sure the new unit fits and connects properly, testing airflow and heat output, and confirming everything meets current code requirements. We don’t rush it. A furnace installed wrong can cost you thousands in wasted energy over its lifespan, not to mention safety risks. You’re making a 15- to 20-year investment, so we take the time to do it right.
Yes. We offer 24/7 emergency service because we know HVAC systems don’t wait for business hours to fail. When your heat goes out at 11 PM in January or your AC quits on a 95-degree Saturday, you need help now.
About 70% of our emergency calls get resolved the same day because we keep our trucks stocked with common parts for all major brands. That means we’re not showing up just to diagnose and then disappearing for three days waiting on an order. We fix it if we can, right there.
Emergency calls do carry a premium compared to scheduled maintenance, but we’re upfront about pricing before we start. If it’s something that can safely wait until regular hours, we’ll tell you that too. We’re not here to scare you into unnecessary emergency rates. But when you genuinely need immediate help—no heat, no cooling, water leaking, burning smells—we’re available and we respond fast.
A proper heating system maintenance visit includes inspecting and cleaning your furnace or boiler, checking all electrical connections, testing the thermostat, examining the heat exchanger for cracks, measuring airflow, and making sure your system is running safely and efficiently.
We also check your air filter, inspect ductwork for leaks, test carbon monoxide levels, and look for any signs of wear that could lead to a breakdown during winter. The whole process takes about an hour to 90 minutes depending on your system type.
The goal is catching small issues before they become expensive failures. A cracked heat exchanger caught during maintenance might cost $800 to replace. That same crack discovered in the middle of a cold snap when your furnace quits could mean emergency rates, no heat for your family, and potentially a full system replacement if the unit is older. Annual maintenance pays for itself by extending your system’s life and preventing emergency breakdowns. Most manufacturers also require regular maintenance to keep warranties valid.
Age is the biggest factor. If your system is under 10 years old, repair almost always makes more sense unless you’re looking at a catastrophic failure like a dead compressor. If it’s 15 to 20 years old, you’re in the judgment zone where repair costs need to be weighed against remaining lifespan.
Here’s a simple rule: if the repair cost is more than half the price of a new system, and your unit is over 12 years old, replacement usually makes better financial sense. A $2,000 repair on a 17-year-old AC might buy you two more years. That same $2,000 as a down payment on a new system gets you 15 to 20 years of reliable cooling with better efficiency and lower energy bills.
We’ll never push you toward replacement if a repair makes sense. But we will give you honest numbers about what you’re spending, what you’re getting, and how long it’s likely to last. If your energy bills have been creeping up, if you’re calling for repairs every year, or if your system can’t keep up with temperature demands anymore, those are all signs replacement might be the smarter move. We’ll walk through the math with you and let you decide.
Yes. Indoor air quality problems usually show up as persistent dust, musty odors, allergy symptoms that won’t quit, or stuffiness even when your HVAC is running. A lot of this traces back to your system—dirty ducts, inadequate filtration, humidity issues, or mold growth in the unit itself.
We start by identifying the source. Sometimes it’s as simple as upgrading to a better filter or adding a whole-home air purifier. Other times it requires duct cleaning, humidity control, or UV light installation to kill mold and bacteria. If you’re smelling something musty from your vents, that’s often mold in the evaporator coil or ductwork, which needs professional cleaning.
New Cassel’s humidity in summer creates perfect conditions for mold growth in HVAC systems. If your system isn’t removing moisture properly, you’ll notice it in the air quality. We can install dehumidifiers, improve ventilation, and make sure your AC is actually doing its job of pulling humidity out. Better air quality isn’t just about comfort—it’s about health, especially if anyone in your house has asthma or allergies.
