Not only do you get to hear a Lennox XC21 turn on and run; I show you the furnace install and indoor components as well!
Everytime I get back to see an XC/XP model Lennox I am blown away. Quietest running of any American unitary system hands down. Two things make the Lennox so quiet: Fan Blade Design and Compressor Dog House. Kudos to my installers Chris and Jacoby for doing such clean, awesome work!
Also, this is listed at 71 decibels....uh, go listen to the XC14 2.5 ton I posted (also at 71 on the listing)...this xc21 as video'd today is more in the low 60s. I have a feeling that fan noise is not considered on brochure listings....but then again, it is insanely quieter, so not sure what they are thinking. -wes
