Frequently Asked Questions

• How often should I get my AC serviced? In Diamond Bar, CA, your AC needs a "tune-up" at least once per year (ideally in the spring) to keep it running efficiently and catch these problems early.
• Is it better to repair or replace my old AC? We will give you an honest answer. If your system is old and a repair is very expensive, we will tell you. But often, a simple repair can keep your system running efficiently for years.
• Do you repair all brands? Yes. Our licensed technicians are trained to service all major makes and models of air conditioners.
• My AC smells "musty" or "dirty." What is that? That is often the smell of mildew or dust on your evaporator coil or in your ductwork. This is an air quality issue that our air duct cleaning service can solve.
