Rated 1 out of 5 by MTabaccki This product does not push enough heat. I am very disappointed in my new furance. It does not heat the house properly. Blows pea warm air not hot. Run's way more than my old furnace ever did. I'm am now affraid of what my gas bill will be. We also had a new air conditioner put in I hope it cool 's the house and doesn't run like the furance. Not a happy consumer! March 31, 2014
Rated 5 out of 5 by VanOrdenMan 3 years and no problems Had the furnace and AC upgraded when we moved into this house. The previous one looked like it was made in the 1950's, so needles to say this Lennox was a great improvement. 3 years on it still runs like new. March 28, 2014
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
