Received a HVAC call for a home-goods retailer in City of Industry, CA. Receiving area was reportedly warm, and manager wanted all units checked. EMS panel was also offline. Upon arrival, tech found the fresh air opening on the receiving room Lennox air conditioner open too far. Made adjustments on the A55 board and closed it. Supply temps back down to 59 degrees. Also confirmed that customer's electrical contractor was already working on the EMS connection issue.
