Hi A..
We have two Lenoxx air conditioners. They were put in when our home was built in 2003. We have had problems with both of the systems. In fact, one of the air compressors went out in 2005. I would not recommend them at all.
I'm not sure where you live, but we always use Reliant Heating and Air ###-###-####. Anytime I've needed them to come service a part or check something out, they have been able to be there that day. Plus, the technicians they send out are really nice and knowledgeable too. Good luck!
