Luxaire Acclimate Furnace Reviews

"Great furnace!"

5.0 rating
Very Satisfied

My wife and I had a Luxaire Acclimate modulating gas furnace installed about 6 months ago. Wow! What a difference it has made. The furnace is so quiet when it is running. Shamefully, I called the contractor back thinking that the furnace was not working, but it was! It was just that quiet! The contractor highly recommended Luxaire and let us know that the parent company was Johnson Controls. We liked the high efficiency, excellent warranty (we also purchased labor coverage for 10 years) and the fact that our purchase was supporting the Make a Wish foundation. We also had an Luxaire Acclimate air conditioner installed at the same time and are equally happy with it. I would highly recommend this product if you are considering it.

I am a heating contractor with 20+ years experience installing Carrier/Bryant, Lennox, Keeprite, Goodman/Amana and Trane/American Standard plus more furnaces & air conditioners. I installed the new lp9c series modulating gas furnace in my own home and my in-laws home. I have had Luxaire furnaces in previous homes and family members home for many years and have had no problems with any furnace that I have installed. Don’t get confused between a poor product with a poor installation. If I would put one in my in-laws home I would put one in your home too!

I have had Luxaire furnaces and air conditioners in all four of my homes. Over forty years of service they have provided my family with reliable comfort. I recently built my retirement home and had the new Luxaire Acclimate fl9c 100 stage modulating furnace installed. The cooling unit is a Luxaire acclimate al5b 2 stage 15 seer utilizing r410 refrigerant. This was the best decision I could have made. We are extremely comfortable and you barely hear the units running. Luxaire, Keep up the good work.

Questions and Answers


What do i do to correct four red flashes from the LED indicator?


I found this: "4 RED FLASHES: This indicates that a primary or auxiliary limit switch has opened its normally closed contacts. The control will operate the supply air blower and inducer. This condition may be caused by: dirty filter, improperly sized duct system, incorrect blower speed setting, incorrect firing rate or faulty blower motor. Also, this fault code could be caused by a blown fuse located on the control board."

If you feel up to it you could try cleaning or replacing the filter. If the filter is too dirty it won't let air flow through it properly, which will trip a safety feature.

Acclimate Warranty

The LP9C and LPLC gas furnaces carry the following warranty:

  • Limited lifetime warranty on the heat exchanger
  • 10 year warranty limited warranty on all other parts

To qualify for this warranty, customers must register their furnace within 90 days of installation. Failure to do so would result in a five-year limited warranty on parts only.

As an added benefit, if customers purchase an Acclimate furnace along with a matching two-stage heat pump or air conditioner then the purchaser qualifies for the 10 years total coverage, as part of the Performance Promise Plan. In the event the home is sold, the plan can be transferred to the new homeowner.
