Not Cooling - Upstairs System 13 year old Trane AC & Coil System not cooling due to failed starting components on outdoor unit. Condenser fan motor is weak dual capacitor has failed. The condenser coil is impacted with debris. The evaporator coil is dirty and has an abundance of rust on it. The heat exchanger has 2 large cracks a few small ones that are also starting to rust. The system does not have enough return air and has to small of a supply plenum. This is why the heat exchanger cracked prematurely. I went over some different options with the homeowners and hey decided to due a band-aid repair to get the system some what cooling today since they have 3 kids bedrooms on the upper level. They requested we send out an install supervisor and I have booked that appointment for this afternoon. The new equipment may have to be laid down (horizontal application) to have enough room for proper application. Thank you for choosing T.E. Certified, have a great weekend!
