Jan 2026 I was without heat in my condo - geothermal unit was seemingly tough to get serviced. Dave from Groundsource was recommended by a local company and he came through with flying colours. Others wanted time and visits and so on. Dave arrived as soon as he could, easily diagnosed the problem (I knew it was the compressor so I was ready) and he installed a new unit the next day on his way home. WOW! Great service in a timely fashion when I had originally thought I was going to have a hard time. YEAH! Thanks Groundsource and thanks Dave!

Dave Thompson is an honorable businessman and he performs his services with skill and efficiency for fair rates. He had the correct tools to do the job, and quickly provided a diagnosis, and no BS recommendations for a path forward.

Called a lot of places to get my parents' geothermal system serviced, but no one was able to help us but Dave. He was able to come the next day and came (more than) promptly. Helpful and friendly!
