Lennox HVAC Systems in Medford, NY
When you choose a Lennox system for your home, you deserve a dealer who knows the product inside and out. Central Air Systems has been Long Island's First Lennox Premier Dealer for years, earning the highest recognition Lennox offers — including the Centurion Award and Partner of the Year. With 37 years of service behind us, we bring the kind of hands-on Lennox expertise that most contractors simply cannot match.
Whether you need a new air conditioner, heat pump, furnace, or indoor air quality solution, our NATE Certified technicians install, repair, and maintain the full Lennox product lineup. We carry everything from the flagship Dave Lennox Signature Collection to high-value Merit Series equipment, and we stand behind every installation with the training and precision that earned us Premier Dealer status.
What It Means to Work With a Lennox Premier Dealer
Not every HVAC contractor can call themselves a Lennox Premier Dealer. This designation is reserved for companies that meet Lennox's highest standards for customer service, technical installation quality, and ongoing training. Central Air Systems was the first company on Long Island to earn this distinction, and we have maintained it through decades of consistent performance.
Our technicians complete continuous Lennox-specific education covering new equipment models, refrigerant handling, and advanced diagnostic techniques. This training goes beyond standard HVAC certifications and ensures we can install and service every Lennox system to factory specifications.
Lennox requires Premier Dealers to maintain a customer satisfaction rating above four stars. We take this seriously — our commitment to clear communication, clean jobsites, and reliable follow-up keeps our reputation strong across Suffolk County and beyond.
As a Premier Dealer, we carry the complete Lennox catalog. That includes the Dave Lennox Signature Collection — their most advanced, efficient, and quiet equipment — along with the Elite and Merit Series for homeowners who want Lennox reliability at different price points.
Lennox offers extended warranty options exclusively through Premier Dealers. When we install your system, you get access to warranty coverage that protects your investment for years. We handle all warranty registration and claims directly.
Premier Dealers receive priority access to Lennox parts, technical support, and factory resources. If your system needs a component, we can source genuine Lennox parts faster than independent contractors who lack this dealer relationship.
When you work with Central Air Systems, you are not just hiring an HVAC company — you are getting the dealer Lennox trusts most on Long Island.

Long Island's Most
Recognized Lennox Dealer
Awards and Recognition
Central Air Systems is not just a Premier Dealer — we have been recognized with Lennox's most prestigious awards, placing us among the top HVAC contractors in North America.
Lennox Centurion Award
The Centurion Award goes to the top-performing Lennox dealers each year, generally representing the top 5% or top 100 dealers in each region. Winners are selected based on customer service excellence, installation quality, sales growth, and brand commitment. Earning this award means our customers receive a level of service that ranks among the best in the country.
Lennox Partner of the Year
The Partner of the Year Award is one of Lennox's most exclusive honors. It is frequently awarded to only one company per district, recognizing the dealer who leads their local market in professionalism, consistent growth, and superior customer care. Central Air Systems has earned this distinction as a reflection of the trust Long Island homeowners place in our work.
What These Awards Mean for You
When you hire a Centurion Award winner and Partner of the Year, you are working with a company that has been vetted and recognized by the manufacturer itself. These are not self-awarded titles — they represent measurable performance across thousands of customer interactions. Our award history gives you confidence that your Lennox installation or repair is in the most qualified hands on Long Island.
Lennox Product Lines We Install and Service
We work with the entire Lennox residential lineup. Here is how Lennox equipment serves Long Island homeowners across every major HVAC category.
Lennox Air Conditioning Systems
Long Island summers bring heat and humidity that demand reliable cooling. Lennox air conditioners — from the ultra-quiet, high-efficiency Signature Collection units to the dependable Merit Series — are engineered to handle exactly these conditions. As a Premier Dealer, we match you with the right tonnage and SEER rating for your home's square footage, insulation, and ductwork layout. Our AC installation and replacement team handles every step from load calculation through commissioning.
Lennox Furnaces
When temperatures drop on Long Island, your furnace becomes essential. Lennox furnaces offer AFUE ratings up to 98.7%, meaning nearly every dollar you spend on heating actually heats your home. The Signature Collection models feature variable-speed blower motors for consistent comfort and lower energy bills. We handle furnace installation, repair, and annual maintenance for all Lennox gas furnace models.
Lennox Heat Pumps
For homeowners looking to heat and cool with a single system, Lennox ducted heat pumps deliver year-round comfort. These systems work efficiently in Long Island's four-season climate, providing cooling in summer and supplemental or primary heating in winter. We install and service the full range of Lennox heat pump models. Learn more about our heat pump installation services.
Lennox Indoor Air Quality — Healthy Climate
Lennox's Healthy Climate product line addresses the air quality concerns that come with sealed, energy-efficient homes. We install Healthy Climate UV lights and air scrubbers that neutralize airborne contaminants directly inside your ductwork. Combined with high-performance air filtration systems, these products reduce allergens, bacteria, and odors throughout your home.
Finance Your Lennox System
A new Lennox HVAC system is a significant investment in your home's comfort and value. Central Air Systems partners with Service Finance to offer 0% interest financing for 60 months on qualifying Lennox installations. That means you can upgrade to a high-efficiency Signature Collection system and spread the cost over five years with no interest charges.
The application process is straightforward. Our team can walk you through your financing options during your free in-home consultation, or you can apply ahead of time. We believe every Long Island homeowner deserves access to top-tier Lennox equipment regardless of budget constraints.
Lennox Maintenance Plans
Protecting your Lennox investment starts with regular professional maintenance. Our residential and commercial maintenance plans include seasonal tune-ups, priority scheduling, and diagnostic checks that keep your system running at peak efficiency. Regular maintenance also preserves your Lennox warranty coverage — many warranty claims require proof of annual professional service.
Long Island's climate puts real demands on HVAC equipment. Salt air, summer humidity, and winter freezes all take a toll. Our NATE Certified technicians know exactly what to check on every Lennox model to catch small issues before they become costly repairs.
Our headquarters at 22A Scouting Blvd, Suite 2, Medford, NY puts us in the heart of Suffolk County with fast response times to communities across Long Island. Whether you need a new Lennox installation or service on an existing system, our trucks are on the road daily serving homeowners throughout the region.
As the area's most recognized Lennox dealer, we bring factory-trained expertise to every home we visit. Long Island homeowners trust us because we combine national-level Lennox recognition with the responsiveness and personal attention of a locally owned company.
