Today we got an inspection on our a/c- heating unit. It was installed 11/20, so it is just over 2 y/o. The tech found three leaks in the coil. can you believe this! 2 mos past warranty. I am NOT happy with this! This is a Lennox unit. I thought they were suppose to be better than this. The old generic unit lasted 16 yrs w/o issue. Needless to say Im not happy about the added cost to this very expensive unit. My complaint is with The unit, not the service person
