Customer Question

Hi, I am having a problem with my ac unit, 2 days ago it was so cold outside in va it was 15 F. The house was was on 75 and my sister felt so worm at night so she opened the window and slept for couple of hours. Then in the morning it was cold inside the house 65F. And since then I see the aux word on the screen and the temp doesn't go obove 69. I don't hear the ac when it comes up. This is the upstairs unit. The main floor unit is working fine. How can we fix this? Thanks
