Dispatched our Valencia, CA, air conditioning technician to a health center for their winter maintenance. Visual inspections performed on all units and air filters changed. All systems are operational, but the tech did find one 7.5 ton A/C with a fan motor that was overheating. We recommend the motor be replaced before it fails, and will quote necessary repairs to the customer.

An urgent car center requested emergency AC service for their specialty department. Our commercial technician found the Trane unit's control board flashing, which required a reset and a reprogramming. Control board back online. Also noted that the filters for the units are all very dirty and should be replaced. Sourced filters locally along with a new belt for #2 and made repairs same day. Thermostat programmed per staff request. Job complete and space comfortable again.

A clothing retailer in Valencia California reported issues with their kids' department air conditioner. Upon arrival the technician found a commercial Trane system starting up with two compressors when calling for only 1 stage of cooling. Troubleshooted by removing control board and testing with a thermostat, and walking through programming with EMS. Discovered an issue with the y1 calling and the unit registering a "heat" call, bringing on both compressors. Work with EMS who will adjust the settings on the boards to correct the issue.
