In this episode Matt sits down with Justin Coleman from Ground Loop Heating & Air to uncover one of the best-kept secrets in home energy efficiency: geothermal heating and cooling. From cutting energy bills by up to 80% to outlasting traditional HVAC systems twofold, geothermal technology is redefining what it means to live sustainably—without sacrificing comfort. Matt and Justin dive into how it works, when it makes sense (and when it doesn't), and why solar panels often fail to add real estate value while geothermal can quietly pay for itself.
