I'm about to replace my 22 year old furnace with a Lennox

Customer Question

I'm about to replace my 22 year old furnace with a Lennox EL296v. The installer says my Nest 3rd gen won't work with this unit.

Let me grab a manual. Most likely the reason is the new furnace has a variable speed motor.

Expert:  airheatman replied 1 year ago.

Yes, this is why it is not compatible, Nest had received numerous requests about this , but currently the existing thermostats they make do not support the variable speed fan on the new furnace.

Wish I had better news s I am sure you like the Nest but currently it is not compatible.You will probably need to use the iComfort from Lennox
