I just moved into a home in TN and the previous owner left no info on this subject.
I would like to know how you use the e-heat on the AC. Also if it gets too cold here will the outside compressor units freeze up. Thanks for advance for any info you can provide.

Sorry this is all the information I have had time to provide at the moment. I'll try to get some more done this weekend.
