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.

Jodi, serviceman was very polite, should me the difference between my filter on the furnace that was being replaced to a new one. Tuned furnace and checked out the air conditioner. Very welcome visit.
