AC unit not blowing cold or hot air... Just air...

Hello guys,

First time poster on this marvelous site.. I had someone install a wall unit for me and it was working perfectly for two years... However when they installed it, the wire were and freon pipes were all hanging outside the wall. So what i did was i opened the wall and pushed the wires and pipes inside the wall. Before closing the wall, i tested the unit and it was working fine, the ac was working wonderfully. After two days of testing, i closed the wall, and then the ac wouldn't blow cold air anymore. I did this last fall and i live in Montreal, so i wasn't too worried about it because at that time, the temperature outside was rather cold already about 50-60F.. I thought that the room was cold enough that why the AC wouldn't work... but now we are in winter, and my unit can also blow hot air... i run it to heat, and all it comes out is pure air with no heat...

Any ideas?? thanks in advance!

Post the make and model of your wall unit.

I suspect the wire connected to the Y terminal is cut (if you even have a Y terminal).

I don't know what you have unless you post pictures or give me the model and make of the unit.

Is this a window unit?
Is the a PTAC style unit?
Is this a minisplit?
Is this a Bard type wall unit?

Need more information.
