A/C not cooling, Small Copper pipe COLD and Large Copper pipe room temp.
I just moved into a newly constructed townhome and the a/c units are of course new. The A/c is not cooling at all. The machine inside turns on as well as the one outside. The inside A/C makes a strange sucking sound kind of like if you were sipping something out of a cup with a straw and you ran out of whatever you were drinking. I'm assuming it's low on freon but I'm no expert or novice for that matter. One thing I did notice is that the small copper pipe in the inside unit is super cold and the big insulated copper pipe is just room temperature. The conditions of the pipes never differ, the small one is always cold and the large one is always room temp, nothing more and nothing less. Can someone please help me? I don't want to A/C tech taking me for a ride saying I need this and that.
Thanks in advance for your help.
