A distribution center in Camarillo, California, requested a commercial HVAC technician to look at their heat. Our tech arrived and found unit #2 not working. The low voltage fuse tripped, due to shorted electrical wiring. After repairing short, tested and found no further issues. Customer requested a replacement thermostat on unit #3 because the push buttons were hard to move. Tech installed the new thermostat, hooked up electrical and tested. Customer happy and site comfortable again.
