Resolving a Tiny Issue at No Charge for a Loyal Customer

Problem: One afternoon in the middle of January, Thornton homeowner Gary C. received a call from his mother explaining that her furnace wasn’t turning on. That was cause for concern, so Gary needed someone who could make the trip to her home in a timely manner. Lucky for Gary, Cooper has lightning-fast response times. We were able to get a technician out to her home quickly to look into the issue.

Solution: Our technician arrived at Gary’s mother’s home and quickly located the issue: a dirty flame sensor. Gary, who had arrived to assist his mother, had no trouble working with the tech to brush away the dirt keeping the sensor from operating. With such a fast resolution, our technician didn’t charge Gary and his mother a penny. Gary appreciated that gesture so much he left us this glowing 5-star review below. Thank you, Gary. We’ll see you next time!

"I will definitely call this company when I need anything…"

Connor from the Cooper Green Team called me back after my mom’s furnace wouldn’t stay on late at night. He helped me find the flame sensor so I could clean it. The furnace started working again with no charge. I will definitely call this company when I need anything related to heating.

—Gary C. | Thornton homeowner
