The Lennox class action in the news is an antitrust case: since March 2026, homeowners and contractors have accused Lennox and six other big HVAC makers of coordinating price increases on air conditioners, furnaces and heat pumps since 2020. Lennox denies it. As of October 2026 there is no settlement, no claim form and no deadline. A separate, small Washington job-applicant settlement has already closed for claims.

What the Lennox Lawsuit Alleges
The lead case began as Berg v. Robert Bosch LLC, filed March 20, 2026 by a Minnesota homeowner. It names Lennox International Inc., Lennox Industries Inc. and Allied Air Enterprises LLC alongside Bosch, Carrier, Trane, Daikin, Rheem and AAON — companies the complaint says control more than 90% of the U.S. HVAC equipment market.
The lawsuit alleges that, beginning no later than January 1, 2020, the manufacturers agreed to “fix, raise, maintain, and/or stabilize” equipment prices. It says they did it through “secret meetings, information sharing, communications, and public signaling” — including a members-only data exchange run by the industry trade group AHRI and price-increase announcements in a trade magazine.
Lennox is quoted heavily. The complaint cites the CEO saying in July 2023 that “industry pricing remains disciplined,” and the CFO saying in 2026 that the industry had “generally been disciplined for the past several years” and that “we’re gonna continue to increase our pricing.” Plaintiffs read that as signaling. Raising prices because a rival did is legal; the plaintiffs must show an actual agreement.
Case Details
The cases are consolidated as In re HVAC Equipment Antitrust Litigation, No. 2:26-cv-10949, in the U.S. District Court for the Eastern District of Michigan, according to Lennox’s own quarterly reports to the SEC. Additional complaints followed in April 2026 — including one by a Florida HVAC contractor on behalf of businesses that buy equipment directly, which alleges an overcharge of about 8%. On July 10, 2026 the plaintiffs filed three amended, consolidated complaints; the indirect-purchaser version runs 191 pages on behalf of 39 named homeowners and other end users. Lennox’s Form 10-Q for the quarter ended June 30, 2026 describes the case.
Status: Early Antitrust Case, No Settlement
Two other Lennox cases show up in searches but are not this one: a Washington job-posting settlement (claims closed July 13, 2026) and a 2015 evaporator-coil settlement (claims closed in 2016). Both are explained below.

Who Could Be Covered
If you are looking for a class action lawsuit Lennox customers can join, this is the one that matters. Price-fixing case: the proposed class is everyone who bought HVAC equipment in the U.S. from January 1, 2020 to the present that was made by one of the defendants, for use in a home or commercial building. That includes Lennox-made brands such as Lennox and Allied Air products. Most homeowners bought through an installer, which makes them “indirect purchasers” — the group in the Berg complaint. Contractors and dealers who bought from the manufacturer are in the separate direct-purchaser track.
You do not sign up for anything now. If a class is certified or a settlement is reached, a court-appointed administrator will publish notice. Keep your installation invoice showing the brand, model and date — that is the proof a future claim would likely ask for.
Washington job-posting settlement: covers people who applied for a Washington job with Lennox International, Lennox National Account Services or Lennox Industries between January 1, 2023 and April 15, 2026, per settlement summaries. Class members were notified individually with a Notice ID and PIN.
Is There Any Money?
For Washington job applicants: in Spencer v. Lennox International Inc., et al., King County Superior Court, Case No. 25-2-21274-2 SEA, Lennox agreed to pay between $384,260.90 and $557,500, depending on how many people claim. Settlement trackers estimated $1,560.70 to $5,000 per claimant. Claims had to be filed by July 13, 2026, and that deadline has passed. The final approval hearing was set for August 14, 2026. One tracker reports approval was granted that day and that payments go out about 60 days after final approval. We could not confirm the payment date on the official settlement website, administered by Simpluris.

October 2026 — Antitrust Case Pending
The price-fixing case is in early pretrial proceedings. No settlement, no claim form and no deadline exist for HVAC buyers.
Three Things to Watch For
A big-name case, millions of HVAC owners and no claim form is the gap scammers like to fill:
“Claim your Lennox AC refund” pages
There is no settlement in the HVAC price-fixing case, so there is no refund portal. A site asking for your Social Security number, bank details or a “filing fee” to reserve a share is collecting data, not filing a claim.
Old coil-settlement links recirculating
Pages about the evaporator-coil settlement still circulate. That program closed for claims on February 1, 2016. It does not pay anyone for a coil that fails today; a warranty claim through your dealer is the real route.
Late “Lennox job settlement” messages
The Washington job-posting settlement only covered applicants who received an individual notice with a Notice ID and PIN, and claims closed July 13, 2026. A message offering to “reopen” your claim for a fee is not from the administrator.
Lennox Class Action — Questions People Actually Ask
What is the Lennox class action lawsuit about?
The current Lennox class action lawsuit is an antitrust case. It alleges that Lennox and six other HVAC manufacturers coordinated price increases on residential and commercial equipment starting in 2020, in violation of Section 1 of the Sherman Act. Lennox denies the allegations.
Is there a Lennox settlement I can file a claim for?
Not for HVAC buyers. As of October 2026, the Lennox lawsuit over HVAC pricing has no settlement, no claim form and no deadline. The only recent Lennox settlement was for Washington job applicants, and its claim deadline was July 13, 2026.
I bought a Lennox air conditioner or furnace. Am I affected?
You may be in the proposed class if you bought defendant-made HVAC equipment in the U.S. on or after January 1, 2020. The class has not been certified. Keep your purchase and installation records; there is nothing to do now.
Which court is handling the Lennox lawsuit?
The U.S. District Court for the Eastern District of Michigan, under the caption In re HVAC Equipment Antitrust Litigation, No. 2:26-cv-10949. The first complaint was filed March 20, 2026.
Who else is being sued besides Lennox?
Bosch, Carrier, Trane, Daikin, Rheem and AAON, plus related companies. The complaint says the group controls more than 90% of the U.S. HVAC equipment market.
How much could HVAC buyers get?
No one knows. The complaints seek unspecified damages. A contractor’s complaint alleges equipment cost about 8% more than it would have in a competitive market. That is an allegation, not a finding, and not a payout estimate.
Is the Lennox job-posting settlement email real?
The settlement is real: Spencer v. Lennox International Inc., et al., King County Superior Court, Case No. 25-2-21274-2 SEA, administered by Simpluris. It covers only people who applied for Lennox jobs in Washington. Claims closed July 13, 2026.
What about the old Lennox coil lawsuit?
Thomas v. Lennox Industries Inc. settled claims that uncoated copper evaporator coils sold between October 29, 2007 and July 9, 2015 corroded and leaked. Benefits included a $75 service rebate and up to $550 for labor and refrigerant. The claim deadline was February 1, 2016. That settlement is closed.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
