Dispatched our Hanford CA HVAC technician to a commercial property that was reporting several cooling issues. Upon arrival, our tech found that none of the units onsite were cooling. Inspected units #1 and #3, both brand new, and found them only pulling hot outside air in through the economizers. #3 also had a loose Y connection that was preventing it from calling for cooling. Bypassed both economizers to get units to cool, will need to replace both economizer boards and sensors. Unit #2 had no 24v going to the control board, traced the issue back to a tripped smoke alarm. Reset and tested, condenser fan motors are locked up. Will need to quote for all repairs including fan motors, economizer boards and sensors. Unit #2 is off to protect the compressor.
