  1. So far, I regret buying my Lennox ml189 furnace. Do not have problem with the heat, my problem is the annoying whining noise it started making one month after installation. Installer came out and said that’s the noise it makes, could not hear the whining noise I hear. The noise was not there in the beginning or I would of never wrote the check. Called Lennox to complain, said I have to pay for another service call from a different Lennox dealer, before I could file complaint. Was also told by installer to close my doors to my furnace room and insulate with blankets. Will not accept this and will continue to fight for a resolution
