HVAC Price-Fixing Lawsuit Update: June 2026
From two cases to six, and contractors are now leading the charge.
CEO, Upward Bound Media LLC. 15-year HVAC veteran.
What You Need to Know Right Now
When we published our original coverage of the HVAC price-fixing lawsuit in late March 2026, there was one case: Berg v. Robert Bosch LLC, filed by a Minnesota consumer on March 20, 2026. By the time we updated our contractor briefing in April, a second case (Isom v. Trane Technologies) had been filed by a Florida HVAC contractor.
As of June 2026, at least six separate federal lawsuits have been filed in the U.S. District Court for the Eastern District of Michigan. The plaintiff pool has shifted decisively: HVAC contractors and dealers are no longer just the subject of this story. They are driving it.
One of those newer suits has already filed a motion to consolidate the contractor-side cases into a single coordinated action, a procedural step that signals plaintiff attorneys believe they have the numbers and the evidence to pursue this at scale.
The Complete Case Tracker
As of June 4, 2026. All six cases are filed in the U.S. District Court for the Eastern District of Michigan. All allege violations of the Sherman Antitrust Act. All seek class-action status.
The Consolidation Motion
The most significant procedural development since April is the consolidation motion filed with Case 6. Husky Heating & Cooling's attorneys asked the court to combine Cases 2 through 6, and any cases filed afterward, into one coordinated action on behalf of all direct purchasers.
This is a standard and strategic move in large antitrust litigation. When multiple similar cases land in the same court, judges frequently consolidate them into what is called a Multi-District Litigation (MDL) or a single lead case to avoid redundant discovery and inconsistent rulings.
What this means for contractors
If consolidation is granted, the direct-purchaser contractor class will be prosecuted as a unified front. One set of lawyers, one discovery process, one set of class-certification arguments. That typically accelerates the timeline toward either a ruling or a negotiated settlement, though "accelerated" in federal antitrust litigation still means years, not months.
No ruling on the consolidation motion has been publicly reported as of the publication of this article.
What the Defendants Are Saying
Both Carrier and Trane have gone on record. These are the only official manufacturer responses confirmed by credible trade press as of June 2026.
Carrier Global Corp.
"We deny the baseless allegations in this lawsuit and will fight it vigorously. Carrier embraces competition and operates lawfully and with integrity."
Confirmed via Facilities Dive email, May 2026.
Trane Technologies
"We strongly dispute the allegations made in this lawsuit and intend to vigorously defend ourselves against these baseless claims. Trane remains committed to operating with integrity, complying with applicable laws and regulations, and providing value to our customers through our sustainable, reliable solutions."
Confirmed via Facilities Dive email, March 2026.
Daikin disclosure note. No public statements from Daikin, Bosch, Lennox, Rheem, or AAON have been confirmed by trade press as of this writing. Daikin Industries did disclose the lawsuits in a corporate filing, stating it "is currently difficult to reasonably estimate the impact of the lawsuits on its business results and that similar litigation could arise in the future." Reported by Refindustry, May 2026.
The Evidence Driving the New Filings
Every case filed since April closely mirrors the evidence laid out in Berg v. Bosch and Isom v. Trane. The attorneys filing these suits are reading the same complaint and seeing the same pattern.
The Lennox CFO Quote
This is the most damaging piece of evidence on the public record. The Isom v. Trane complaint quotes Lennox CFO Michael Quenzer at a July 2025 industry conference:
"The next [pricing] level will be early next year when we all come out and announce our next full round of price increases. For the balance of the year, I think we're pretty well set from a price perspective. Next year, we'll do our annual price increase, and just like we always do, we expect similar results by others."
Antitrust attorneys call this "conscious parallelism" signaling: a public announcement of pricing intentions designed to be heard by competitors, not just shareholders. The phrase "we expect similar results by others" is the part plaintiff attorneys are leaning on hardest.
The Hagens Berman complaint quotes a separate Lennox executive statement that goes even further:
"We're gonna continue to increase our pricing to maintain our margins. I think others have generally been as well. You know, we, as an industry, have realized that pricing, you know, taking it away, does not win market share."
ACHR News as the Coordination Mechanism
The Berg complaint alleges manufacturers used ACHR News (the industry's own trade publication) not just to announce price increases, but to signal those increases to each other before they were communicated to distributors and contractors.
First documented instance: Johnson Controls (now Bosch) announced a "price increase of up to six percent on residential and commercial heating and cooling products" in August 2020 via ACHR News. Trane announced an identical 6% increase on September 30, 2020. The pattern repeats dozens of times from 2020 through 2025.
The Production Cut Admission
When residential demand softened in 2025, manufacturers chose supply restriction over price competition. The Isom complaint documents a Trane executive publicly stating the company had cut factory production by one-third, then adding that he did not want anyone to think prices were coming down. Lennox confirmed a parallel production cut within days.
In a competitive market, lower demand leads to lower prices. In a coordinated market, lower demand leads to supply cuts to preserve price levels.
The Numbers Behind the Cases
HVAC equipment prices rose more than 50% from January 2020 through early 2026. The gap between HVAC equipment inflation and comparable benchmarks is the statistical backbone of every complaint filed.

What Happens Next: The Legal Roadmap
These cases are in their earliest stage. Here is the process from here, in plain English.
- 1
Consolidation ruling
The court will decide whether to combine the six contractor-side cases into one coordinated action. If granted, one lead counsel will be appointed to represent the direct-purchaser class.
- 2
Defendants respond
The manufacturers will file motions to dismiss or answers to the complaints. This is where their legal arguments for why the cases should not proceed will be laid out formally.
- 3
Discovery
If the cases survive motions to dismiss, both sides enter discovery. Plaintiff attorneys will subpoena internal communications, pricing-meeting records, executive emails, and AHRI data-sharing documents. This is where cases like this either collapse or get very strong, very fast.
- 4
Class certification
Plaintiffs must convince the judge that there is a certifiable class. This is the most contested phase and often takes 18 to 24 months in cases of this size.
- 5
Settlement or trial
Most large antitrust class actions settle before trial. The 1960s Electrical Equipment Conspiracy resulted in criminal convictions and hundreds of millions in civil settlements. There is no guarantee here, but the pattern is consistent.
Realistic timeline. Any contractor payout is 3 to 5 years minimum, assuming the cases are not dismissed.
What Contractors Should Be Doing Right Now
If you are an independent HVAC contractor who has purchased equipment from any of the Big Seven (Carrier, Trane, Daikin, Bosch including the former Johnson Controls residential line, Lennox, Rheem, or AAON) since January 2020, you are potentially in the direct-purchaser class.
Preserve every invoice going back to January 2020
PO numbers, model numbers, distributor names, prices paid. If your accounting software has this data, back it up in a format you can access independent of that platform.
Do not alter historical pricing records
Document retention is critical in class-action participation. If you destroy records, even accidentally, it could affect your ability to participate in any eventual settlement.
Register your interest with plaintiff law firms
Scott+Scott (lead firm on the Isom v. Trane contractor case) has a public intake form at scott-scott.com/global-antitrust/did-you-pay-too-much-for-hvac-equipment/. Registering costs nothing and creates no obligation.
Check your state's Illinois Brick Repealer status
If you are in one of the 30+ states with an Illinois Brick Repealer law, you may have a recovery path under state antitrust law in addition to the federal direct-purchaser class.

The earliest any settlement funds could realistically reach contractors is several years out. The contractors winning right now are the ones owning local search and keeping their phones ringing. That is what actually protects your margin today.
