Dispatched to investigate why the upstairs was not cooling down to desire temperature. Friday when I was here, the downstairs was the topic of my interest. I did verify that the refrigerant charge was at manufacturers specifications. There was only a 10° split from the return to the supply temperature when I got here. Found that the evaporator coil is suffering from a restriction. We are scheduled to come and change it out under parts and labor warranty on August 6, 2024. The system was installed January 23, 2023. Cost of the labor is under AC Pros warranty for two years. Recommendation would be to purchase the 10 year extended labor warranty for $1050 per unit.
