Colliers is top notch! They are knowledgeable, professional and fair. We received excellent customer service and they went above and beyond what was expected- which is alot to say these days! I would recommend Colliers to anyone looking to service or replace their geo thermal.

After learning from our annual cleaning that we needed a new A/C, Doug came out quickly and gave us a great quote. Installation was a few days later and all went smoothly. This is our 2nd A/C with Collier's with the last being installed 10 years ago. We are loyal customers because we have been very happy with their service all these years.
