Questions before you call
How quickly can you respond to a commercial AC failure in Lafayette?
Call us with the address, unit type and symptoms and we'll give you the first available time. Lafayette is about 29 miles southwest via SR-4, I-680 and SR-24 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.
