Collis Heating and Cooling is just plain amazing. Over the years we've had them do yearly services, installation, inspection and emergency repairs. Top notch service. Everyone is very friendly, informative and helpful. I definitely recommend them. Well - if you want things done right, in a timely fashion and with a smile.
I had my draft induction motor seized up on a Friday. Call Fred F Collis in Yorkville that day and was told that there was nothing they could do until Monday. They said that they would call back Monday afternoon but I had to call them back. The part was not available until Wednesday. Once the part was in they came over replaced it real quick. They even called me the next day and asked if everything was still running well. There was just a little miss communication at the beginning but other than that great service.
I called Collis for furnace repair and they were awesome! They were able to send someone right away and had us up and running in no time. The guys were friendly, knowledgeable and followed up with us the next day to make sure everything was good. Great service.
