Earth River Geothermal Heating and Cooling Reviews

We are so honored and grateful to have a 100% customer satisfaction rate.

Here are some of our geothermal customers' much appreciated reviews:

“We are delighted with the new system. The house is more comfortable than ever before, and the system is completely unobtrusive. It's so quiet I can't tell when the blower is on. ”
—J Carley

“We've been very pleased over the last few days with the system. Between the geothermal and zoning, our house has never been more comfortable.”
—B Wuerdemann

“Since you know I like to collect data on my new system, we now have an entire year with our new system so I thought I would share our savings with you. Obviously, the weather was not identical each year, but the overall average is pretty close. In the 12 months before we got the system, our total electric cost was $5,168.98. Of that, $3,368.98 was the heating/cooling portion.

In the 12 months following the installation of the geo system, our total electric cost was $3,321.77. Of that, $1,521.77 was the heating/cooling portion.

So, our new system lowered our overall electric bill about 35%, but more impressively, it cut our heating/cooling costs more than in half (it lowered our heating/cooling costs about 55%). And the best part is that we got to keep our house a little cooler in the summer and a little warmer in the winter, so we could have saved even more keeping the same setpoints at the old system. Plus, we never run out of hot water now. So, bottom line, if we keep saving on average at this rate, after you take the tax credits, grants, and projected cost of replacing our initial bad air handler, our projected return on this investment will be 8 years. Needless to say, we are very happy with our decision to do this.”

“Great service and good quality. Mark initially spoke as knowledgeable of both the mechanics and the geology that this type of job [entails]. He also stepped up immediately to tackle concerns that I had and was very responsive. [The geothermal heating and cooling system] performed as expected saving a fair amount of money on electricity while increasing overall comfort.”

“Our energy costs are about 1/3 less ... We are keeping the house several degrees warmer this winter than before, and the temperature during winter months has averaged a couple of degrees colder. So the comparison is even better!”

“We think ERG is superb... Our energy costs are lower after the retrofit. We would recommend Earth River Geothermal to a neighbor or friend any time it comes up. Plus we'll take reference calls from your prospects. It’s not a big deal if they come out of the blue; just send me a quick email [before they call].”
—K Avery

“We are very happy, satisfied and pleased with our system, the service and the company Earth River. I have already spoken to several of your potential customers and would be happy to continue doing that for you...We are very happy for your help in getting us a better grant from MES than we were originally told we would get. Mark is great about communication on all these things. Thanks again!”
—D.S

“Mark has been great at responding to all my questions; that, and the ability to have one contract, sold me on Earth River.”

“Geothermal heating is a 'no brainer'... We can continue to enjoy the house, be more energy efficient, and have a greener planet. We’re trying to make a little bit of [a] difference.”
—J.M.

“We were pleased with the year to year comparison this first [full post-install] month. Even after accounting for a three degree higher than average temperature. 11 therms versus 134 therms is rather compelling. Our bill was $263 lower despite what I'd imagine are equal or higher per-therm prices year over year... The incalculable soft benefit was that this year we maintained a comfortable 70°F whereas last year we did the typical thermostat gymnastics and would allow it to get a bit chilly at times. Pun definitely intended, we're rubbing our hands together anticipating a cold month's savings!”

“We decided to use Earth River because of Mark: his integrity, other values and technical smarts. His responsiveness to my multitude of technical questions.. plus, his pricing beat the pants off of [the competition].”
—B.D.

“All has been good. I would be happy to serve as a reference.”
