Geothermal Heating & Cooling on Long Island
Lower your energy bills and boost comfort with GreenLogic geothermal. Our systems utilize the steady temperature beneath Long Island to heat and cool your home more efficiently than traditional HVAC systems — saving you money for decades.
Geothermal systems use the steady underground temperature — about 50–60°F year-round — to heat and cool your home. Unlike traditional HVAC that fights against extreme outdoor air, geothermal moves heat in and out of your house using underground loops. The result? Consistent comfort, dramatically lower energy use, and a system built to last decades.
Why GreenLogic?

Let Us Illuminate You
Our Infrequently Asked Questions section (IAQ) will shed some light on the things you need to know when considering geothermal
How does a geothermal system work?
Geothermal systems use underground loops to move heat in and out of your home. In winter, they extract heat from the earth and bring it inside; in summer, they pull heat out of your home and return it underground. This process delivers consistent comfort with much lower energy use.
How much can I save with geothermal?
Homeowners typically cut heating and cooling electricity use by up to 50% compared to traditional HVAC. Over the life of the system, those savings often outweigh the upfront cost.
Can I combine geothermal with solar energy?
Yes! Pairing geothermal with solar is the ultimate clean energy combo. Geothermal lowers your electricity demand, while solar provides renewable power to run the system—bringing your home closer to true energy independence.
