This is another reason why you should always make sure your electrician is completely qualified to work on whatever problem you are experiencing. This mistake caused a great deal of discomfort to the employees and customers of the business because the roof top unit could not run at all. Make the safe, smart choice and call Approved Comfort whenever you have an issue with your electricity.
A local business owner called us because his roof top unit was not running. When we arrived at the business we found that the thermostat was blank. We determined the cause of the problem was when a previous electrician moved the thermostat he tried to hook the duct sensor back into a loop. However, he wired it incorrectly, causing the circuit to pop a low voltage fuse. We rewired the thermostat with a new duct sensor and installed a new low voltage fuse. Once we did that everything worked fine.
