Rated 4.4 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Self Install This furnace is a very good value for it's pricing..........was fairly easy to install (for a couple of rookies). Would recommend. September 14, 2014
Rated 5.0 out of 5.0 by Good value Unit works very well. Easy product registration. The tricky part was getting it installed. The service contractor (for installation) was EXTREMELY uncooperative, they did not provide any type of cost breakdown in any estimate (even when prompted by the store), and I ended up going through an outside contractor for half the price. December 25, 2012
Rated 5.0 out of 5.0 by Huge $$$$$ Savings Can't believe how many "thousands" of dollars I saved by buying my furnace from Home Depot and having a local contractor install it for me. Great quality and price. September 26, 2013
Rated 5.0 out of 5.0 by So Far , So Good I can only rate the Install quality at this time. The directions where simple and it was a very smooth replacement of my old unit. One recommendation is Do Not Buy the Plenum kit as it was a waist of money. Took the new measurements to a Duct & Sheet metal company and in one hour a new Plenum. September 1, 2014
Rated 5.0 out of 5.0 by FAIR PRICE, NICE UNIT…... Furnace was damaged durning shipping, appeared to be from forks on fork lift. I straightened out the sheet metal the best i could and installed it not wanting to waste time with a return. July 8, 2014
Rated 1.0 out of 5.0 by JUNK with a capital J. Try to buy parts, not if, but WHEN it breaks down! Low quality meant for DIY people that have no idea how to install. Winchester should only be selling guns. Check ratings before buying....nothing good about them. Do not believe these reviews written by their staff. February 10, 2015
Rated 5.0 out of 5.0 by compact size and easy to install Arrived in the time frame stated. A lady from shipping called me before shipping to review the order. Easy to pick up at the store . Worked right away after installing runs quiet. December 17, 2013
