The Geothermal Process: Retrofit of 2000 Sq Ft home in Brighton, CO 80603

Three 300-foot loops were drilled, headered, and manifolded into the basement where the heat pump was located. The outdoor AC condensing unit was also removed. A 4-ton geothermal heat pump and two hot water heaters for heating domestic hot water took the place of the less efficient furnace. The owner also added solar panels to offset electrical usage.

Geothermal in School in Aurora, CO 80018

Colorado Geothermal Drilling installed the geothermal system at the new Aurora Public Schools Harmony Ridge P-8 in Aurora, CO. 100 geothermal loops and 83 ground source heat pumps are providing fossil-fuel-free energy-efficient heating and cooling. It’s safe because there is no onsite combustion of fossil fuels, efficient because, for every 1 unit of energy consumed, geothermal delivers 4 or more units of heating and cooling.

Geothermal system installed by Dan in 2009. He helped prevent major installation problems by the HVAC company. My system has been flawless for more than 7 years now and he was less than 1/2 the cost of the second bid. You can't get any better.

We have had a great experience both with Dan Rau and the system itself. Our house is all electric due to utility logistics and when we purchased it the heating and cooling system no longer worked. Dan and his crew drilled our holes and installed the pump units very efficiently and professionally. He recommended a heating and cooling contractor to run ducting, etc. who was also great to work with.
We have had the system now for 4 years. It operates well and even in house with poor insulation our bills are very reasonable and the system is comfortable. I am also giving Colorado Geothermal a 6th star because a few months ago I noticed the pressure in the system had dropped and Dan came right out and found the problem, fixed it and left with no charge. Awesome.

As a Geothermal Drilling Consultant I have known Dan Rau since 2006 and have worked with him on numerous projects. In 2014 had him do the drilling on a new home my wife and I built. With my long term knowledge of Colorado Geothermal Drilling and other drilling companies I would not use anyone else. Dan has a consistent history of being competitive and a performance record that is unmatched in the Industry.
Because Dan drills for over 50 HVAC contractors, he can either work with your HVAC contractor or recommend a experienced Geothermal HVAC contractor for the complete installation that will have maximum performance for the comfort of your home.

Colorado Geothermal Drilling did a fabulous job doing the underground drilling for our new geothermal system. They were quick, efficient and professional. Dan was very knowledgeable and helped us understand the whole process. We have had our system installed for almost a year now and are very impressed with it! We highly recommend this company if you are thinking about installing a geothermal system.

We are so happy with the geothermal in our new house. It is one of our favorite things! Colorado Geothermal drilling are fantastic people! Seriously cheap heating and a bonus cooling in the summer! Our heat bill in winter was about $60 in the coldest month for 3,000 sq feet! Not even joking! A cool 70 degrees all summer is costing us $25/ month! On top of that it's not a dry heat, there's the perfect amount of humidity in the air! Unlike typical forced air. It's almost unbelievable. Best decision we've ever made!!
