The company’s comments, in its own words

(4/9/2021) LENNOX INDUSTRIES, INC.: Lennox prides itself on the quality and safety of its products and takes claims of leakage very seriously; however, Lennox disagrees with the consumer’s assessment and her recitation of the steps Lennox took to resolve the issue. The consumer’s Lennox EL296 furnace meets all applicable safety standards and is independently certified as such. According to the Lennox contractor who installed the furnace, the furnace had not been serviced by that contractor since its installation in 2017 in contravention of explicit warnings and instructions accompanying the product. Further, when the consumer contacted the contractor with concerns of possible leakage, the contractor offered to provide the consumer with a replacement heat exchanger free of charge when he made the determination that the heat exchanger within the furnace had failed. The consumer rejected his offer and demanded a replacement furnace. At this point, the contractor reached out to Lennox. Because Lennox takes pride in the quality and safety of its furnaces, Lennox agreed to provide the consumer with a new replacement furnace and arranged for one of its internal field technical consultants (FTC) to speak with the contractor and consumer to further investigate the cause of the leakage. Unfortunately, the FTC was told that the subject furnace had already been replaced with another brand. At the same time, upon learning of the consumer’s concerns with her furnace, Lennox’s Customer Support attempted on three occasions to reach out to the consumer for additional information. As of this filing, the consumer has not returned those calls.
There are a number of reasons why the consumer’s carbon monoxide detector may have detected carbon monoxide beyond a heat exchanger failure, but, unfortunately, Lennox has been unable to determine the actual cause of the consumer’s issue because the unit has already been replaced and the consumer has not responded to Lennox’s multiple attempts at outreach. Lennox cannot determine the reason for the issue without access to the equipment itself. Lennox notes that the consumer’s report notes that she is still in possession of the unit; Lenox encourages the consumer to return its calls so that Lennox can arrange to have the unit evaluated to determine the issue.

The product, in the report: G26Q3-75-1 Furnace

I owned a Lennox G26Q3-75-1 furnace. In December of 2018, we noticed a strong smoke smell in the room with the furnace. When we entered the room, it was full of smoke and the furnace was on fire. We have contacted Lennox to let them know of the problem and see if they wanted the damaged furnace so they could research and find out why it caught on fire. This was their response: “Dear Mr. [REDACTED]:
Thank you for your email.
We at Lennox Industries, Inc. value all of our customers, and it is our policy to provide the highest quality product. As you are aware, someone must identify the specific reason for your current furnace damage. There are a number of reasons why this could occur, however we are not in a position to evaluate the cause. We rely on your dealer’s guidance to identify the root cause of an incident and determine the best plan going forward.
We would like to take this opportunity to make you aware of the importance of having routine maintenance performed to help ensure proper and efficient operation. Lennox recommends that the system be serviced by a qualified service technician at the beginning of each cooling and/or heating season. While this service generally includes a check of all major system components and equipment operation, it also allows the technician to identify and eliminate any concerns such as outdoor debris or other contaminants that may have entered your furnace intake. Regular maintenance performed by a licensed HVAC contractor helps to prevent more costly repairs and damage should those concerns be left uncorrected.
With regard to your G26Q3-75-1 furnace (Serial Number 5893K51522), we do not need you to return it to us. We encourage you to continue consulting with your servicing contractor to meet your personal comfort needs.
Sincerely LENNOX INDUSTRIES INC.
[REDACTED] Consumer Support”
I am concerned about the safety of other person’s homes that may have this furnace. I wanted to make a formal complaint to let people know of this problem that this furnace could potentially have.

Incident, No Injury

The company’s comments, in its own words

(4/18/2019) LENNOX INDUSTRIES, INC.: The consumer reports that his furnace caught fire. Nobody was injured. Although the consumer excerpted in his post a letter that Lennox sent to him, there are additional facts that the consumer chose not to share.
First, the Lennox G26Q3-75-1 furnace’s serial number indicates that it was built in October 1993. This furnace meets all applicable safety standards. Among one of the furnace’s safety features is a “rollout switch” that detects any excessive heat from the furnace’s burner box and, if detected, shuts down the furnace to prevent any fire.
Second, Lennox arranged for the installing dealer to promptly investigate the consumer’s report of a fire. According to the dealer:
• The furnace had not been serviced by that contractor since 2000, about 18 years. • The air intake pipe from the outside to the furnace had melted. The contractor indicated that there was very little damage to the furnace. • The melting of the air intake pipe strongly suggests that debris, such as leaves, had accumulated in the air intake pipe, eventually entered the furnace, and ignited both in the burner box of the furnace as well as in the air intake pipe.
Third, Lennox wrote its letter to the consumer after the dealer had completed its initial investigation and had reported to Lennox. Based on the dealer’s initial report and photographs, Lennox believes that the likely cause of the fire was the consumer’s failure to service the furnace and the buildup of debris in the air intake pipe eventually spilled into the furnace and ignited. For that reason, Lennox’s response to the consumer stressed the importance of regular service. It further encouraged the consumer to continue working with the dealer both to confirm further that the fire was caused by accumulated debris in the air intake pipe and to ensure proper maintenance of the furnace in the future.
In short, Lennox’s G26Q3-75-1 furnace meets all applicable safety standards as designed. It should also run safely for two decades and beyond if it is installed, maintained, and serviced properly. However, just as cars need to have regular maintenance performed (their oil changed and tires and brake pads replaced periodically, etc.), so, too, do furnaces require periodic maintenance. Lennox recommends maintenance each heating and cooling season.
