Review by on Tuesday, November 12, 2013

I have used this unit for about 9 years now. Pretty much been trouble free. Blower fan went out (about $400 part) it was covered under warranty. I cleaned for the first time the other day. Annual cleaning is important. Unit was a bit pricey but I am overall satisfied with performance.
