Fort Collins homeowner wowed by our wealth of AC knowledge

Problem: Fort Collins homeowner, Tim, needed a new AC system. After giving the Cooper Green Team a call, we scheduled a convenient time for a free, in-home estimate with one of our AC experts, Terry, who would analyze Tim's home's setup and provide customized AC recommendations.

Solution: Tim was so pleased with Terry's wealth of knowledge and attentive service, he knew it was a no-brainer who would install his cooling system. Now that he's enjoying his new AC, Tim is thrilled to recommend Cooper Heating and Cooling for educated advice and 100% satisfaction.

Had Terry Cannon come out to my home to have AC set up. He was the most thorough, educated and responsive rep I could have asked for. If you’re considering AC in your home, please waste no time and give Terry Cannon with Cooper Heating & Cooling a call. 10 out of 10 I would highly recommend!
