Serving Clayton
Clayton is about 17 miles southwest via SR-4 and Kirker Pass Road from our Antioch shop, and we serve all of it, including Dana Hills, Clayton Wood, Oakhurst and Cardinet Glen. Clayton is almost entirely single-family homes, so commercial HVAC work here is modest, centered on smaller buildings and facilities such as Oakhurst Country Club. When a rooftop unit or split system fails at a Clayton business, we diagnose it on site and quote the repair before work starts.

Questions before you call
How quickly can you respond to a commercial AC failure in Clayton?
Call us with the address, unit type and symptoms and we'll give you the first available time. Clayton is about 17 miles southwest via SR-4 and Kirker Pass Road from our Antioch shop.
Do you repair rooftop package units?
Yes. Rooftop package units are the most common commercial system we see, and most failures - capacitors, contactors, belts, blower motors, refrigerant leaks - can be repaired on the roof.
When should a commercial unit be replaced instead of repaired?
When it's near the end of its service life, uses R-22, or the repair costs approach a large share of a new unit. We'll put both options in writing.
