Cursed 5 ton zoned system.
Hi everyone, i need help as i feel ive run out of ideas. I have a two zone 5 ton carrier ac in my new 2800 sq ft home. It is two stories. I have had two separate companies out at least seven times each trying to fix problems with condensation on the outisde of the air handler in the attic and the system tripping the DATS sensor for too cold.
Tonight i measured the air temp with a probe just after the evap coil and it read 53 degrees. The air before the coil read 77 degrees. I also measured some places on the exterior of the air handler with a infrared sureface gauge and got readings in some places at 55 degrees and at others 45 degrees!
What is wrong with this cursed system causing it to sweat so badly and get surfaces so cold???
