Rated 2 out of 5 by Windy44 Below average furnace The furnace keeps home warm--but it is the noise that makes me sorry I purchased it. I can hear the burner and fan noise at a level that is disturbing. I am surprised your company would produce a furnace this noisy. I believe I will have to replace it and take a big loss.

Rated 1 out of 5 by WMan LOUD I recently installed a lennox ML180UH gas furnace & it is sooo loud it sounds like the salimander heater in the barn. We've converted it from natural gas to lp & we have excessive burner noise. Any ideas?? January 21, 2014

Rated 5 out of 5 by Scott1934 Solid unit; no problems; inexpensive Been using a ML180 (ML180UH090P48B-01) for over 1.5 years so far. No problems. Smaller and quieter than old unit. I wish the user manual would give a description of the meaning of the LEDs though September 22, 2013
Rated 4 out of 5 by Rico Good product I purchased this furnace 2 months ago and have been extremely happy with it. It takes up less space than my old furnace, has lowered my heating bill, and is much quieter and gives more even heat than my previous furnace. I would recommend this product to anyone. May 1, 2013
Rated 5 out of 5 by gizmo Excellent product I researched all the top of the line furnaces and air conditioners. My old furnace was 26 years old as well as my air conditioner, (got my money's worth). The furnace and duct work was installed and completed in two and a half hours. They came back the next day and did the air in an hour and a half. They both perform beyond expectation. Lennox is a Quality Product and I would recommend it to anyone. As for a previous comment on being too loud and powerful, Not too loud, and the system was designed to distribute heat-----Mission accomplished!!!! April 22, 2013
Rated 4 out of 5 by Blueyedone2905 ML180UH Gas Furnace As far as I can tell, it works just like any other heater. I turn on the heat and I can feel it come out instantly, and within 5-10 minutes my house reaches the desired temperature. It's also quiet. The only sound it makes is of air coming through the vents. It's a little disappointing that its only 80 percent efficient, but for the price, this is excellent. I also upgraded to the year filter and I am glad about that. I'm really bad at remembering to change those. Also, I'm really glad it's got so many emergency shut offs, because my old one did not and it flooded the floors and melted some of its wires. Also, I like that its not burning gas 24/7. It seems safer that way. Thank you for a good system. I see nothing wrong with it so far. April 18, 2013
Rated 4 out of 5 by Pakele The efficiency rating is great The efficiency rating is great. Also the ease of accessibility to the air filter and the clean look I like. It also is quiet and provides the proper temp entire selected when needed. April 18, 2013
