Rated 4.2 out of 5 by 10 reviewers.
Rated 4.0 out of 5.0 by Warm & Toasty This equipment is very efficient. Not difficult to install. We are using it to heat four rooms downstairs and the two bedrooms upstairs. It is located in the frontroom. It doesn't blow cold air, just warm air. The rooms are seperated by walls and doors, yet there is only a 4 degree difference from one end of the house to the furnace. Very happy with the relatively quiet operation and even heating throughout the house. It has optional front and side venting that I think we will invest in later. November 20, 2010
Rated 5.0 out of 5.0 by Works well after I repaired defective parts. The fan was supposed to have packing around it, it didn't. Consequently one of the blades was bent. I bent it back and it works until a new fan arrives. The fan motor was out of alignment so the fan was hitting the cowling. I manually bent the bracket , fixing the alignment. The connector on the igniter was broken off. I bought a new one at the hardware store and replaced. There was a small dent in the metal casing, which from other reviews, is pretty common. This furnace could be packaged better, there is no padding in the box it is shipped in. The furnace was relatively simple to hook up if you have experience running gas lines. The manual was confusing in that it gives the impression you can't use flex tubing for the final connection, until you read the fine print. The diagrams are very misleading. It also was wrong about the vent and intake tubes having to be protrude all the way through the vent opening. If you are literal this is not your manual. The factory service was honest about the manual being incorrect. They did send a new fan as soon as I told them the original was defective. Once connected the furnace is a delight. Heats very evenly and the warm air coming out at floor level keeps the floors toasty. The factory service was friendly and responsive to my questions. I'd buy it again but be ready to deal with problems due to poor packaging. Unfortunately that is normal nowadays. Being able to talk with live factory service people is nice. December 25, 2014

Rated 5.0 out of 5.0 by Just the right size for my basement. This is a furance made by Williams. It replaced one that was the same size and manufacture that I had for 25 years. The blower moter failed and they did not have a replacement. But 25 years of trouble service is great! I think ths one will last just as long. November 20, 2011
