Climate Master Geothermal Systems in Medford, NY
Heating and cooling your home with the ground beneath it is not a new idea, but the technology has reached a point where it outperforms conventional HVAC in almost every measurable way. Climate Master builds geothermal heat pump systems that tap into the earth's stable underground temperature to deliver heating, cooling, and even hot water — all from a single, remarkably efficient unit. For Long Island homeowners ready to move beyond fossil fuel dependence and volatile energy costs, geothermal is the most forward-thinking comfort investment available.
Central Air Systems has been installing and servicing Climate Master geothermal systems across Long Island for years, drawing on 37 years of overall HVAC experience. Our NATE Certified technicians understand the unique demands of ground-source installations — from loop field design to system commissioning — and we pair that technical depth with the project management skills needed to coordinate the excavation, piping, and indoor equipment installation that a geothermal project requires.
How a Climate Master Geothermal System Works
Ground-source heat pumps operate on a simple principle: a few feet below the surface, the earth maintains a relatively constant temperature year-round — typically between 50 and 55 degrees on Long Island. Climate Master systems circulate fluid through an underground loop field to exchange heat with the ground, pulling warmth into your home during winter and depositing excess heat back into the earth during summer. Here is how we approach each component of the installation.
The loop field is the foundation of every geothermal system. We evaluate your property's soil conditions, available land area, and heating and cooling loads to determine whether a horizontal or vertical loop configuration is the best fit. Proper loop sizing is critical — an undersized loop starves the heat pump, while an oversized one wastes installation budget without adding performance.
Climate Master manufactures water-source heat pumps in a range of capacities and configurations. We match the indoor unit to your home's calculated load using Manual J analysis, factoring in insulation levels, window area, home orientation, and occupancy patterns. The indoor unit is compact compared to a traditional furnace and air conditioner setup, and it operates quietly.
Geothermal heat pumps work with standard ductwork, making them compatible with most existing homes. If your home uses radiators or radiant floor heating, Climate Master systems can feed those distribution methods as well. We assess your current ductwork condition and capacity during the site evaluation and recommend modifications only when necessary.
Many Climate Master units include a desuperheater — a small heat exchanger that captures waste heat from the cooling process and uses it to preheat your domestic hot water. During summer months, this feature can offset a significant portion of your water heating costs, adding another layer of savings on top of the space conditioning efficiency.
After installation, our technicians commission the system by verifying refrigerant charge, loop flow rates, and airflow across the heat exchanger. We calibrate thermostat settings and walk you through the controls so you understand how to manage your new system. Proper commissioning is what separates a geothermal system that hits its rated efficiency from one that underperforms.
Every Climate Master installation we complete is backed by the same attention to detail that has defined Central Air Systems for 37 years — no shortcuts, no guesswork.

Long Island's Experienced
Geothermal Installer
Central Air Systems brings 37 years of HVAC expertise to every geothermal project, combined with Climate Master product knowledge and NATE Certified installation crews. When you are considering a ground-source system, our experience with Long Island soil conditions and local building requirements gives you a contractor who understands both the technology and the territory.
Our Brand Partnerships
Central Air Systems is proud to carry Climate Master alongside three other leading HVAC manufacturers. This multi-brand approach means we recommend geothermal when it genuinely fits your situation — and we can offer conventional alternatives when a ground-source system is not the right match for your property.
Lennox
As Long Island's First Lennox Premier Dealer, we carry the full Lennox lineup including the Dave Lennox Signature Collection. For homes where geothermal is not feasible, Lennox high-efficiency air conditioners, heat pumps, and furnaces offer outstanding performance. Our Lennox Premier Dealer status — along with the Centurion Award and Partner of the Year recognition — reflects decades of consistent excellence with the brand.
Bosch
Our Bosch Platinum Pro certification gives us access to Bosch's inverter-driven heat pumps and air conditioning systems. Bosch equipment is a strong alternative for homeowners who want high efficiency and quiet operation but whose property constraints make geothermal impractical.
Mitsubishi Electric
As a Mitsubishi Electric Diamond Dealer, we specialize in ductless mini-split systems for homes without existing ductwork. Mitsubishi systems provide zone-by-zone comfort control and pair well with geothermal in hybrid configurations where certain rooms need supplemental conditioning.
We have earned the highest dealer designations from all four of our brand partners, a distinction that very few HVAC companies on Long Island can claim. Explore our Lennox, Bosch, and Mitsubishi brand pages for more details.

Frequently Asked Questions
A Climate Master geothermal system is a ground-source heat pump that uses the earth's stable underground temperature to heat and cool your home. Fluid circulates through a buried loop field, exchanging thermal energy with the ground. The indoor heat pump unit then concentrates that energy to condition your living space year-round.
Most Long Island properties can accommodate some form of geothermal loop field. Vertical loops work well on smaller lots, while horizontal loops are ideal for properties with more land. During a free site evaluation, our team assesses your soil conditions, available space, and heating and cooling loads to determine the best configuration.
Geothermal systems typically reduce heating and cooling costs by 40 to 60 percent compared to conventional equipment. The exact savings depend on your home's size, insulation, current energy source, and usage patterns. Because the system draws free thermal energy from the ground, operating costs remain low and stable regardless of fuel price fluctuations.
A typical residential geothermal installation takes one to two weeks from loop field excavation through system commissioning. The timeline varies depending on loop type, property access, and any ductwork modifications needed. Our team coordinates all aspects of the project so you have a clear schedule from day one.
Yes. We partner with Service Finance to offer 0% interest financing for 60 months on qualifying geothermal installations. Combined with available federal tax credits and state incentives, financing makes the upfront investment much more manageable. Ask about all available options during your free consultation.
Geothermal systems require less maintenance than conventional HVAC because there is no outdoor unit exposed to weather. Annual professional inspections include checking the heat pump unit, verifying loop pressure, replacing filters, and calibrating controls. Our maintenance plans cover all of these services with priority scheduling.
The indoor heat pump unit typically lasts 20 to 25 years, which is significantly longer than a conventional furnace or air conditioner. The underground loop field can last 50 years or more with virtually no maintenance. This longevity makes geothermal one of the best long-term value propositions in home comfort.
Yes. Many Climate Master units include a desuperheater that captures waste heat during the cooling cycle and uses it to preheat your domestic hot water. During summer months, this feature can cover a substantial portion of your water heating costs at no additional energy expense.
