Total Satifaction! These guys are great! We recently decided to replace our old heating and upgrade with air conditioning in our home. We chose Colomb Services after the recommendations from a friend. Their Sales Manager was friendly and extremely knowledgeable. He had answers for all of our questions and concerns. We were scheduled within a week for our installation and the installers were on time and went right to work. All work was completed in a timely manner and I would definitely use them again in the future!
