I noticed my furnace wasn't coming on and house was getting colder. I called Geothermal specialist ,they came that evening and found the problem.  Ordered the part and installed it the next day. So appreciate the timely service. Thank you.

Stephen provided us with a comprehensive and reasonably priced consultation regarding our existing geothermal system. We would recommend him for system design.

We have been using Geothermal Specialists since we moved into our home in 2020, and they have been fantastic to work with. They maintained our previous ClimateMaster system for years and recently installed our new Enertech geothermal system, and the entire experience was excellent.

Steven and the crew are not only extremely knowledgeable, but also genuinely great people. They take the time to explain everything clearly and make sure you fully understand your system. Their work is neat, meticulous, and shows true craftsmanship.

One thing that really stood out was their customer service. A few years ago, our system had an issue late at night on December 23rd. I left a message expecting a call back after the holidays, but Steven personally called me within 30 minutes and helped walk me through getting the system stabilized, then came out as soon as possible to follow up.

After 6 years of maintenance and a full new install, I can confidently say they are trustworthy, professional, and excellent at what they do. I would highly recommend Geothermal Specialists to anyone considering geothermal HVAC.

I am on my second geothermal install with Geothermal Specialist. My original unit lasted almost 20 years with one small repair. When it started to lose its efficiency I called Steve to diagnose the problem. He quickly diagnosed the problem. Due to the age and problem with the unit we agreed that replacement was necessary. He ordered the unit and in a few days called to set an install date. He and his professional crew came and completed my install. When the new unit was started we discovered my discharge pipe which was installed 35 years ago by a different contractor was plugged. Really not his problem. They went back to their shop for additional equipment and returned and worked on it till the problem it was resolved. I recommend them for their prompt professional work.

Big shout out to Stephen VanderWerf and his team at Geothermal Specialist, Inc. A week before Christmas, my 23 year old geothermal unit called it quits. Early that morning, Stephen walked me through several options for reset (no luck). His son arrived a few hours later and worked several hours until our system was limping along with some heat. But recognizing our desperate situation, Stephen worked with another client to move our install to the top of the list. We are back in business with a new system, installed by a thoroughly professional crew, all going the extra mile into the night the day before Christmas Eve. Thank you to for going above and beyond.

Also, doing my due diligence, I got an additional quote from another geothermal dealer. In my case, Geothermal Specialist, Inc. offered me better specs at a slightly better price than the other quote. This company is professional, knowledgeable, and reasonable.
