The contractor who I was most pleased with quoted me both Amana AMV9/ASX14 and Lennox G61V/XC14 systems.
He includes a 5 year labor warranty which most don't offer. Is this somewhat of an equalizer in regard to all of the things that could go wrong that I can't check for in the installation, being a layman?
Also, Amana generally has 10 year warranties on parts, Lennox 5 years? Does this matter?
