Client Testimonials
Having had the system for over a year, I
could not be happier with my forced air heart source pump. The efficiency
is greatest in the summer, when I get 42 degree air out of the vents and
use almost no electricity to cool the house and heat the water! I was
pleased to find out that during the recent cold spell (-8 degrees at times),
the geothermal system easily kept up with the heating needs of my house.
Dan Rau and his crew were invaluable in assuring that the install was
done correctly, and in at least 2 instances, corrected install errors
that would have been impossible to correct after construction was complete.
The system is as quiet as a refrigerator. I'm doing my best to educate
everyone that will listen, but it amazes me how little most people know
about this technology.Brian N., Boulder, CO
I recommend Colorado Geothermal Drilling
to anyone looking to install a vertical geothermal system. I am confident
that his team will not let you down and will leave you with the highest
quality, most efficient loop field that is possible.
Jordan F., Firestone, CO
It was a pleasure working with Colorado
Geothermal Drilling. They showed up when they said they would and they
finished the job in a timely matter. I am very impressed with their professional
approach to getting the work done; from their outstanding drill/grout
rig to their courteous staff. They took great care to make sure the jobsite
was clean and they were very careful to make sure the pipes were pressure
tested before placing them in the borehole. I would recommend them without
hesitation. Brian F., Windsor, CO
