Our customer in Mission Viejo, CA, reported an issues with their heating in one area of the store. The commercial Lennox air conditioner had power, but was not supplying heat. Our technician diagnosed a faulty roll-out switch. He was able to reset it for temporary heating, but the part will need to be replaced. Will quote the necessary repairs for the customer.

A chiropractor's office in Mission Viejo CA was scheduled for HVAC maintenance today. Standard summer, minor service: all filters changed, units inspected and deficiencies noted. System is functional, but has a rusted capacitor that needs to be replaced and a drain line that has cracked. Will quote repairs for customer.

Refrigeration tech returned to a weight loss center in Mission Viejo, CA, to perform approved work. Traulsen freezer #3 was in need of a new capacitor. Tech was able to source and replace. Freezer back to normal operating temperatures, will need to quote failing gaskets but that's not affecting performance at this time.
