"BAD FURNACE"

Very Unsatisfied

I had a Heil furnace installed right before my son was born. The furnace was so loud I couldn’t put him to sleep in his own room. Now I just found out the transformer is blown and is not covered by them. What a joke!

Other N8MPN Reviews

There do not seem to be many serious problems with the N8MPN, judging by comments on HVAC forums. Most of the problems appear to be with a failure to ignite. A consumer on diychatroom.com was advised that his problem was due to a bad board, while contractors on doityourself.com thought that a similar problem was due to the igniter assembly. The problems were not considered overly serious and were covered by the warranty.

N8MPN Warranty

The Heil N8MPN is covered by a 20-year heat exchanger limited warranty and a 5-year parts limited warranty. With product registration, an additional 5 years is added on to the parts warranty.
