“I really appreciate you, Rick.  You showed me my options and why I should go with a heat pump.  Couldn’t be more pleased.  By the way, your techs were polite, cleaned up after themselves, and went over the thermostat with me.  Really appreciated that.  I’ll recommend you every time!”

“Had no idea we’d save this much money on our utility bills with our geothermal system.  And the free hot water in the summer.  How can we not be happy.  Thanks again for a great install.  Your guys were great!”
