Rated 4.1 out of 5 by 60 reviewers.
Rated 5.0 out of 5.0 by purchace was a perfect choice I had to replace a 20 year direct vent natural gas wall furnace, in a hurry, in an apartment rental and this one was perfect. It fit the space perfectly without any alteration; great looking; great quality; looks nicer installed than the old one and installed easily and inexpensively by a professional in a little over an hour. A great feature if the power goes out, it will continue to function. It's perfect for an apartment and compared to other heaters is very reasonably priced. Home Depot shipped it immediately and I received it before they said I would. December 17, 2014
Rated 5.0 out of 5.0 by Easy install, good product I had read some reviews on the furnace before buying. Mine came in with no damage and a good thermostat. I use it to heat a 220 square foot insulated shop in the back of my garage, it is perfect. So far my energy usage is 1/2 of what it was with an electric heater. The furnace will pay for itself this winter. I live in northern NY, it is cold from October to May. November 18, 2014
Rated 4.0 out of 5.0 by I would recomend this heater First off Williams does a poor job of packaging, the cabinet is right on top with no protection, be sure to check for damage! If you convert this heater to LP gas you drop down to 10,000 BTU, they state this in the conversion kit inst. ONLY. The template for the hole it came out a little low, but made it work. The thermostat works good they tell you where the Wht+Red wire go, but not on the unit, I put the Wht wire on the top empty post. I wish Williams would do a better job of packaging cause this is a good little unit.Hope this helps you out GL Tom August 2, 2013
Rated 4.0 out of 5.0 by Solid Heater I bought this product for my Ice House. Like other reviews stated the Heater showed up damaged!!! It's extent was only bent sheet metal that I was able to straighten out but if it would have been on the cover It would have been an eye sour. The heater performs very well and is very efficient. I did the LP conversion for it and they did not explain in the instructions that there would be an extra piece for a different pilot burner left over which drove me mad!!! All in all I am very happy with the unit and would buy it again. January 8, 2014
Rated 4.0 out of 5.0 by A few issues The good news, it works. The issues: the corners of the heater were bent, but still able to bend back and put cover on; the thermostat didn't work right. When the installer put the thermostat on and then turned it up the pilate would not stay lit so installer gave us a remote which works well. The vents on the front of the cabinet are bent. So bottom line; quality not so good, but, has been very efficient and the remote works well. I said would recommend only because the price is good and the heater does seem to work well (with modifications, that is) January 20, 2015
Rated 5.0 out of 5.0 by Fairly easy install Went in east enough,turned right on. Had to mess with the gas knob though to get it to light. Worst part was the break in smell; odor was like a chemical factory for a day plus. Run it for a day with all doors open. Afterwards, works like a charm, heats more space than it says it will.

Rated 5.0 out of 5.0 by good dependable little guy Good instructions for installation. Had mine installed for 10 years and it still works without any complaints. code says not to put it to close to a window or door. wish I would have bought the one with a wall thermostat. September 23, 2014
Rated 1.0 out of 5.0 by Williams Customer Service is Terrible I opened the box and the furnace was damaged. Had to bend it back into shape because I didn't want to return it. The directions are not clear so I called Williams Customer Service and they were incredibly rude. The message that I got from them is that if I'm not a "qualified installer", then they don't have the time of day to answer my questions. Every answer they gave to my question was, well...if you were a qualified installer you would know this. I stated that HD sells to homeowners, so shouldn't they expect homeowners to have questions? Their answer - we fully advise homeowners to get a qualified installer to put this in. Okay, I get it - Williams doesn't want to deal with homeowners. If I weren't almost done with the project, I would choose a better company to support with my money. November 4, 2013
