Shannon invited us out today for 2 AC tune ups! I started at the basement unit which overall is running correctly however, it is starting to show its age. There is some rust build up on the coil and the contactor at the condenser is in pretty rough shape. Moving on to the attic unit, initially the condenser would not kick on with a call for cool. I found that the contactor was not transferring proper voltage and that the capacitor was reading out of spec. After solving both of those issues, the condenser still did not kick on.. after quite the search I was finally able to find that a connection at the wet switch had come loose. All in all, both systems are cooling! Thank you for having us out today!
