Well, I don't give anyone five stars. There's got to be room for improvement! But I have been using the services of Tim's Air Conditioning for nearly forty years and they are a good company. They installed my first air conditioning unit in the early nineties. Years later, they replaced that one. And just last year, I got another new air conditioner. They are easy to reach by phone when I need service. In fact, my daughter, Celeste, is the office manager at Tim's Air Conditioning. I think she's doing a fantastic job, too!
