Hey guys I need some help with a problem one of my customers is having. I installed a new 5 ton payne heat pump system with a air handler about six months ago. Unit has been running great.
Since it started getting colder and he had to start running the heat pump he says he is getting an odor like a drity sock. He also told me he had the same thing about ten years ago when he had his unit replaced (the unit I just replaced). He said the contractor tried several things and finally replaced the indoor coil and it went away.
I'm just trying to figure out if payne will warranty the coil because from what I have read up on this problem you have to get a coated coil to solve the problem and that going back with a standard coil will not fix it. Any help would be greatly appreciated.
