Dispatched our Orange County HVAC technician to a mobile provider for approved work. Their #2 air conditioner scheduled to be replaced. Our technicians removed and disassembled the existing air handler, welding and wiring in the new AHU and testing all operations. Confirmed new system is operation and site comfortable.

RESSAC tech arrived onsite at a home goods store in Santa Ana, California, to investigate a water leak and possible AC electrical damage. Manager pointed out fallen ceiling section with exposed insulation, stating roofer had been onsite and reported an open electrical conduit box that had shorted, burned holes in the roof, and then let in the water causing falling damage. Tech was able to locate problem area on the roof, but found it already repaired by the roofer. To help prevent water intrusion, tech sealed the junction boxes. No other issues to report, units running fine.
