Questions before you call
How quickly can you respond to a commercial AC failure in Central Contra Costa?
Call us with the address, unit type and symptoms and we'll give you the first available time. Central Contra Costa is a short drive from our Antioch shop over SR-4 or Kirker Pass Road.
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.
