“Colin was great during our A/C servicing today. He introduced himself, had on the company uniform, and he was very friendly. He took his time to explain in great detail, all of the good and not so good components of our A/C unit. He took pictures and emailed them to us as well. He helped me to understand how our system works, and what would make it work even better. I would definitely recommend him for your A/C servicing needs, so call One Hour and ask for Colin! Thanks again! :)”
