Questions before you call
How quickly can you respond to a commercial AC failure in Discovery Bay?
Call us with the address, unit type and symptoms and we'll give you the first available time. Discovery Bay is about 17 miles southeast via SR 160 and SR 4 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.
