"Best purchase I have ever made"

5.0 rating
Very Satisfied

I was an installer for lennox for a couple of years and I have now totally changed careers but that is besides the point. My slp98v furnace is the best purchase I have ever made, it runs great and never know its even running. I am a strong believer of lennox products and lennox only because to me they are built the best and lennox I feel is always one step beyond everyone else. now a furnace is much like a new vehicle on the market, if you buy something that is brand new and they havent yet been able to work out any of the kinks in the model you may have problems but that is a risk you must take to get quality and reliability! Best part is if something breaks on a new model and it is to do with a fault, it will be covered by warranty. so dont complain and relax you people.
