How Does Geothermal Heating & Cooling Work?

Whether it’s a winter cold snap or a summer scorcher, the ground five feet below the surface maintains a constant temperature year round. This constant earth temperature is higher than average winter temperatures, and lower than average summer temperatures.

Geothermal systems use this difference in temperature to transfer heat between your home and the earth with two key parts:

A heat pump inside your home (usually in place of your traditional system)
Buried pipe systems (called ground loops) circulate heat transfer fluid

The heat pump and circulating fluid continuously transfer heat. During summer, the geothermal system draws heat from the air in your home and transfers it to the ground. During winter, it draws heat from the ground and transfers it to your home.

This Old House recently took an inside look at a Dandelion Geothermal installation in Albany, NY.


What’s the difference between Dandelion Geothermal and a traditional furnace?

Energy Independent

Tap into the endless heat below your yard. Never buy (or run out of) fuel oil again.

Traditional furnaces require sourcing fuel, which is subject to supply and demand and impacted by the political landscape.

2-in-1 heating and cooling

One HVAC system to rule them all. Central heating, air conditioning, AND pre-heated warm water in one smart package.


Low Operating Costs

Consistent pricing you can count on. No more negotiating annual delivery contracts or wondering how the news cycle will affect your heating bill.



More time, less hassle. Say goodbye to frequent maintenance visits, service calls, and heating deliveries.


Increases Your Home’s Value

Invest in your home, and reap the rewards. Save $1,000s on your heating and cooling bills.



Four times more efficient for less than you’re paying now. Higher efficiency = more money saved.



No flames and no fumes. Furnaces have the potential to produce serious health hazards like carbon monoxide, sulfur dioxide, and nitrogen dioxide.


Renewable Technology

Good for the planet (and your wallet). Home heating comes second only to automobiles when it comes to air pollution, and oil-burning furnaces consume more fossil fuels than diesel trucks.


Long-Lasting Equipment

Reliable heating and cooling for decades to come. Geothermal heat pumps typically last 20 to 25 years, and the ground loops installed in the yard can last more than 50 years. Even up to 100!


Tax Incentives

One more reason why 2020 is the best year to get geothermal. Qualify for generous federal, state, and utility tax incentives to lower your costs.
