Lennox Warranty

Lennox offers a 10-year limited warranty on the compressor and all parts which is a good warranty but not the best warranty in the business.  Still, most of their air conditioners, when properly installed and maintained, serve homes well beyond the warranty coverage, with 15-20 years being the norm depending on how heavy the usage has been.
