I switched over to Sterling Services when other service providers either were hard to schedule or were poor in their service. Sterling, on the other hand, has been a pleasure to do business with. It's easy to schedule work with them, and their staff (office staff, service technicians, etc) are very professional and very competent. I am very happy with all of their work (plumbing, A/C, Heat). They are truly best in class.
