CLIENT REVIEWS
I love this company so much. I’ve had trouble with my AC for years and they were the only ones to figure out my problem and get it fixed for good. They just came out again today for a service call and again, it was a great experience. They know their stuff and will get it fixed correctly the first time. You won’t be disappointed. Thrilled I found them!!

Excel goes above and beyond for their customers. I had an urgent issue that needed tending to right away. My phone call to Excel was quick and easy in regards to their after hours response team. I called at 1PM, Jeff Pittman was at my house by 2PM. Keep in mind it’s a Sunday. Jeff stayed at my house for 3.5 hours, taking time away from his own family on a Sunday, to make sure that my family was taken care of and had our system up and running back to normal. I can’t say enough about Jeff and his hard work. He was respectful, and worked his tail off. If you’re looking for any geothermal experts please do yourself a favor and use Excel. First-class all the way. Thanks again, Jeff!

ENERGY EFFICIENT
Geothermal systems use a series of sealed piping loops buried in the ground that tap the renewable energy of the earth. These loops create a better heat transfer medium than traditional air source systems. It is so efficient that the U.S. Environmental Protection Agency has stated:
“Geo exchange systems are the most energy-efficient, environmentally clean and cost-effective space conditioning system available today”
HOW IT WORKS
Wherever you live, the temperature beneath your home remains constant regardless of the season. Geothermal Heat Pump Systems harness the stable underground temperature to provide heating, cooling, and hot water at remarkably high efficiencies.
