“With our research, ClimateMaster is number one. We don’t have any outside units—you can sit on the back porch without the unit clicking on or the fan running in the summertime. This being my last house, we really checked into geothermal, and it’s been the perfect solution.”
“Now I’ve got a certified home that is 78% more energy efficient than my neighbors and 48% more efficient than new builds on the market today. I’m saving about $1,750 to $1,800 a year, and as a bonus, I get free hot water as a byproduct of my geothermal system. It’s quiet—I can hear my neighbors’ air source heat pumps, but they don’t hear mine.”
“We have geothermal—our neighbors don’t, and I know they wish they did. It’s a clean heat, not as drying to the skin, and you can feel the difference. In 6.3 years, we’ll recoup our investment, and after that, it’s all savings. Just plain facts—it saves money. ClimateMaster was the right choice: professional, customer-oriented, and easy to work with.”
