Very professional, prompt service with well qualified technician. Ryan was very cordial, prompt, thorough, and professional. He went out of his way to give me a tutorial on geothermal system operation and maintenance. I found the service exceptional and the quality of personnel exemplary.

Collier's installed our geothermal system in 2010. We have them come out twice a year to perform preventative maintenance on it. Ryan has been our technician from day 1. Speaks volumes that there isn't a constant turn over in technicians. Always friendly and reliable. If there have been any issues, Collier's sends their technician out quickly and we have always been happy with the results. I would highly recommend Collier's for installation, maintenance and service for your heating and cooling needs.
