I have been using City Heating and Air for many years now. I can't remember how many but it's been quite a long time and I've used them several times. They did not install my AC unit originally but we started using them to do servicing after the last provider stopped. I just recently had to have a new AC installed, so hey did do that, and I'm satisfied with it. They are usually able to schedule for service within a day or two, sometimes longer, but more often than not they come quickly and they provide good service in good time. I'm very happy with all the employees I've had from them over the years and the pricing is very reasonable too. I will continue using them and I recommend them highly.
