I highly recommend this company for geothermal designs, installations, repairs, efficiency improvements, plus any plumbing work, hot water heater repacements, running a freezeproof water source outside instead of a hosebib (who knew?), and any other home repairs/enhancements that Gregg says he can do. After going through several questionable geothermal companies, I found it so refreshing to find someone as knowledgeable, professional, creative, honest, hardworking, and just plain nice as Gregg. He and his entire staff will do whatever it takes to get your household systems working, even staying late in emergency situations so you don't have to go overnight without heat or hot water. We've discussed everything that's been bugging me about our house, and Gregg has come up with creative solutions I never would have thought of. He's the first person I would call if anything goes wrong in the house to see if he can fix it.

Gregg and Thom are top notch. I own a building and remodeling company and i am always impressed with these guys work. There knowledge of Geo Thermal systems is amazing. They have become our exclusive HVAC company for all our clients. If you need an HVAC contractor that is knowledgeable and honest, this is your company.

Greg and his team at green hill mechanical are top notch professionals. I had them install two geothermal units (1 4-ton, 1 2-ton split system). They took great care to minimize damage to my yard and were always on time and very responsive. Greg trays every project like its his own home and doesn't cut corners or try to take the easy way out. He's work is top notch and the install of the equipment is gorgeous. All the equipment and wires are installed to perfection. Love my geothermal system and Greg and his team. Hire these guys with no concerns. They don't come any nicer and he's a master artisan with the geothermal installs.
