I have a brand new Rheem indoor/outdoor AC units for my remodeled house. It was installed the summer of 05 and we were under construction and now running it 06. It is two zones. The Tech started them up and both wre running fine. Lately the 1st floor was not cooling. The tech pushed the Red Reset Button on the outside compressor (Resettin it). Now, it is happening again. What is the common cause for having to keep pushing the reset button? Now I think it tripping more frequently. I have a call in to the Tech, but was wondering what you guys think it is. Probably a typical problem for a NEW unit. Thanks
PS: 2nd floor is fine.
