Ducted Heat Pump Installation and Replacement in Medford, NY
Heating and cooling your Long Island home with two separate systems means two sets of maintenance, two points of failure, and two pieces of equipment consuming energy year-round. A ducted heat pump consolidates both jobs into a single system, moving heat in during winter and pushing it out during summer — all through your existing ductwork. For homeowners looking to simplify their comfort setup while cutting energy costs, a heat pump is one of the smartest upgrades available.
Central Air Systems has been installing ducted heat pump systems across Long Island for 37 years. As Long Island's first Lennox Premier Dealer and a Bosch Platinum Pro, we carry heat pump equipment engineered for the demands of our regional climate — including cold-climate models that maintain heating capacity well below freezing. Our NATE Certified technicians design and install every system based on your home's specific requirements, so you get reliable performance in every season.
What Goes Into a Professional Heat Pump Installation
A ducted heat pump installation involves careful planning and precise execution. Each step in our process is designed to ensure your system delivers the efficiency and comfort that heat pump technology is known for.
Before recommending any equipment, we evaluate your home in person. A NATE Certified technician inspects your ductwork condition, insulation levels, window placement, and overall layout. We perform a Manual J load calculation to determine exactly how much heating and cooling capacity your home requires. This step prevents the common problem of oversized or undersized equipment, which wastes energy and shortens system life.
Heat pumps come in a range of configurations — single-stage, two-stage, and variable-speed models with different capacity and efficiency ratings. Based on your load calculation, we recommend options from Lennox and Bosch that match your home's needs and your comfort preferences. We explain the differences between SEER2 and HSPF2 ratings so you understand what each system delivers in both cooling and heating modes. Your comfort advisor walks you through warranty coverage, rebate eligibility, and financing options so you can make a well-informed decision.
Your ductwork is the delivery system for your heat pump's conditioned air. Before installation day, we inspect your ducts for leaks, restrictions, and damage that could undermine system performance. Leaky ductwork can reduce efficiency by 20% or more, so addressing these issues before the new equipment goes in is essential. If modifications or repairs are needed, we handle them as part of the project.
Our installation crew removes your existing equipment and prepares the site for your new heat pump. The outdoor unit is positioned on a proper mounting pad with adequate clearance for airflow and service access. The indoor air handler or coil is connected to your ductwork, refrigerant lines are brazed and pressure-tested, and all electrical connections are made to code. Every detail follows manufacturer specifications and local building requirements.
Once the physical installation is complete, we commission the system by verifying refrigerant charge, airflow volume, thermostat operation, and defrost cycle function. We test the system in both heating and cooling modes to confirm performance across the full operating range. Before we leave, we walk you through thermostat programming, filter locations, maintenance basics, and warranty registration. You will know exactly how to operate and care for your new system.
A heat pump installation is only as good as the team behind it. Our process reflects 37 years of field experience and a commitment to getting every detail right the first time.
Signs It May Be Time for a Heat Pump Upgrade
Whether you are replacing an aging heat pump or switching from a separate furnace and AC setup, there are clear indicators that a new ducted heat pump makes sense for your home.
If several of these apply to your situation, reach out to our team for a no-obligation home assessment. We will evaluate your current setup and help you determine whether a heat pump is the right fit.

Heat Pump Brands We Install
Choosing the right heat pump starts with choosing the right equipment. We carry systems from three manufacturers, each bringing specific strengths to ducted heat pump applications on Long Island.
Lennox
As Long Island's first Lennox Premier Dealer, we offer the full Lennox heat pump lineup including the Dave Lennox Signature Collection. Lennox heat pumps are built for quiet operation and high efficiency, with select models reaching up to 24 SEER2 and 10 HSPF2. Their variable-capacity compressors adjust output continuously to match your home's demand, providing consistent temperatures and lower energy consumption compared to single-stage systems.
Bosch
Our Bosch Platinum Pro certification reflects specialized training on Bosch's inverter-driven heat pump technology. Bosch ducted heat pumps use variable-speed compressors that modulate output based on real-time conditions, maintaining tight temperature control while minimizing energy use. These systems are designed to deliver reliable heating performance at outdoor temperatures well below freezing — an important consideration for Long Island winters.
Mitsubishi Electric
As a Mitsubishi Electric Diamond Dealer, we install Mitsubishi's ducted heat pump solutions for homes that need flexible zoning and precise climate control. Mitsubishi's Hyper-Heating INVERTER technology maintains full heating capacity at extremely low outdoor temperatures, making their systems a strong choice for homeowners who want heat pump efficiency without compromising winter comfort.
Central Air Systems has earned the Lennox Centurion Award and the Lennox Partner of the Year Award — honors reserved for the top-performing dealers in North America for outstanding customer service, installation quality, and brand commitment.

Your Central Air Systems comfort advisor can walk you through the application during your in-home consultation. Approvals are typically fast, and additional financing terms are available if a different payment structure works better for your budget.
Heat Pump Maintenance Plans
A new heat pump system delivers its best performance when it receives regular professional attention. Our maintenance plans include seasonal tune-ups for both heating and cooling modes, priority scheduling when you need service, and discounts on any repairs that come up.
Heat pumps work year-round — unlike a traditional AC that sits idle all winter — so routine maintenance is especially important for preserving efficiency and extending equipment life. Long Island's coastal humidity, salt air, and seasonal temperature swings create additional wear on outdoor components, making professional maintenance a smart investment from the day your system is installed.
Our installation team serves homeowners throughout Suffolk County and the surrounding areas from our Medford headquarters. From older Cape Cod homes in the western towns to newer construction out in the Hamptons, we bring the same attention to detail and technical precision to every heat pump project.
Every home on Long Island presents its own set of conditions — ductwork age and layout, insulation quality, exposure to coastal weather, and heating fuel costs all factor into system design. Our 37 years of local experience give us the insight to account for these variables and recommend a heat pump configuration that performs reliably year after year.
Frequently Asked Questions
Yes. Modern ducted heat pumps, especially cold-climate models from Lennox, Bosch, and Mitsubishi, are engineered to deliver effective heating at outdoor temperatures well below freezing. Inverter-driven compressors adjust output to maintain warmth even on the coldest days Long Island experiences, making heat pumps a viable primary heating source in our climate.
A heat pump moves heat rather than generating it. In summer, it works like a central AC by removing heat from your indoor air. In winter, it reverses the process and pulls heat from outdoor air into your home. This eliminates the need for a separate furnace and reduces the number of systems you maintain and replace over time.
Most ducted heat pump installations are completed in one day. Projects that involve ductwork modifications, electrical panel upgrades, or complex layouts may extend to a second day. Your comfort advisor will outline the expected timeline during your in-home consultation.
Look at both SEER2 (cooling efficiency) and HSPF2 (heating efficiency). Higher numbers mean lower operating costs. The systems we install range from standard-efficiency models to premium variable-speed units with SEER2 ratings above 20 and HSPF2 ratings above 10. We help you balance efficiency, features, and budget during the selection process.
In most cases, yes. We inspect your ductwork during the home evaluation to confirm it can support the airflow requirements of your new heat pump. If we find leaks, restrictions, or sizing issues, we address them before installation to ensure optimal performance.
We do. Through our partnership with Service Finance, qualified homeowners can take advantage of 0% interest financing for 60 months. Additional terms are available, and your comfort advisor will walk you through options during your consultation.
A professionally installed and regularly maintained ducted heat pump typically lasts 15 to 20 years. Because heat pumps run year-round, consistent professional maintenance is important for maximizing equipment life and maintaining efficiency over the long term.
Heat pumps often qualify for utility rebates, manufacturer promotions, and federal tax credits due to their energy efficiency. Availability changes periodically, so we help you identify current incentives during your consultation and factor them into your investment decision.
