Can anyone answer this air conditioning question for me.
My daughter lives in a two story house, with two units, one for downstairs and one for upstairs. Downstairs unit is working and cooling okay, upstairs unit runs all the time (blows air but the air does not feel cool at all) and it is beyond hot up there. My son-in-law says it is from the heat rising from 1st floor and the high temps outside and his solution is to open a window up there and put a fan in to blow hot air out. I say the upstairs unit is not working right and needs to be checked for problems. Anyone offer suggestions? Thanks!!

I would recommend getting an energy assessment on their house since it could be one or many of these things. The it is not a matter of the heat rising from the first floor in the Summer. Heat is coming down from the hot attic. It will heat up to 140 degrees in the attic today. I am also assuming that they live in the South. What is the temp in the attic? Did it work last year?
Could you please tell me who would do an energy assessment?
Thanks for your response SawHorse, Inc. I appreciate it!

You did not say if it was a window unit or system with fan inside and large compressor located outside. If its the latter you can do a look see if the outside system is running or not.
Be sure to turn on AC control down so the system begins to run. Then go outside and check to see if the outdoor unit is running. If not, there should be a switch mounted on the wall. Open it and ...»
If the outdoor unit is running then you need a charge of refergerant.
