My name is Marc and I run a 4000 sq ft washateria with 2 ten ton Carrier split units. Units were installed last June and appeared to run perfectly. However, one of the units started shutting down and not coming back on everyday recently. I noticed that this only happens on days that outside temperatures are in the mid 90s. I have had 2 technicians from two different companies look at it with no results.
One said that we are overworking the compressor and it shuts off as a safety measure and the other came out and put a wind baffle on top of unit. Of course those two charged me for their time with no results are I wouldn't be here now.
My question is if we are overworking the unit why does one run fine and the other one shutting off when it gets hot. They are both located behind building about 20 ft from each other. These technicians aren't cheap. I don't mind paying to get the problem fixed but they are charging me and giving me no results. Can it be a defective compressor? Does anyone have any insight on this. I'm desparate for any help.
Thanks in advance,
