The word geothermal contains the suffix -thermal. If you remember your Ancient Greek root words, or you’ve encountered thermal underwear at some point or know about “thermal detonators” from Star Wars, then you know thermal means heat. Geothermal power has something to do with heat—heat from the earth. (Putting those Greek roots to work again!) So when we tell you about options for geothermal air conditioning for your house, you might wonder if we’ve gone a touch batty. How can a geothermal system work to cool down a home?
The answer: extremely well! Geothermal heat pumps are effective ways to provide comfort to a household all through the Michigan year. Like a standard heat pump, a geothermal heat pump brings heat into a building during cold weather and removes heat during warm weather. And it does these jobs at higher efficiency than a standard heat pump.
