Customer called for no air conditioning. Customer stated that the blower was moving air through the home but it was room temperature. Upon inspection I found the wires from the disconnect switch to the condensing unit damaged do to mice. The line voltage wires had their protective rubber coating chewed off which exposed the copper that was shorting out the condensing unit. Replaced the half-inch whip from the condenser to the service disconnect and tested the system. Found the breaker for the condenser to be faulty as well. After whip replacement I couldn’t get the breaker to properly reset. Happen to have a 30A 240V 2 pole breaker on the truck. Replaced the current breaker and tested system again. System started up without issue. Tested the temperature split between the supply and return. System was operating with a perfect 20° differential. System is now operating properly at this time. Recommend replacing the dirty Merv 11 16x25x4 air filter due to dirty buildup.
