The HVAC price-fixing lawsuit landscape just shifted. Seven of the largest HVAC manufacturers in the United States are now facing a wave of federal antitrust complaints, and HVAC contractors are leading the latest charge.
Trane, Carrier, Daikin, Lennox, Rheem, Bosch, and AAON stand accused of conspiring to inflate the price of heating, ventilation, and air conditioning equipment since January 2020.
What the HVAC Price-Fixing Lawsuit Alleges
The complaints accuse the seven manufacturers of running a coordinated, multi-year scheme to fix, raise, and stabilize HVAC equipment prices across the United States.
- The agreement to fix, raise, and stabilize prices began no later than January 1, 2020.
- Prices increased by more than 50% during the period in question.
- By 2025, equipment was about 68% more expensive than in 2019, while raw material costs had returned to near baseline.
- The seven defendants together control over 90% of the U.S. HVAC market.
The lawsuits cite executive statements as supporting evidence. One quoted comment captures the tone the plaintiffs are pointing to: “I don’t want anyone to think that pricing is coming down in that market.”

Why the HVAC Price-Fixing Lawsuit Matters for Contractors
If the allegations hold, contractors have spent six years buying equipment at artificially inflated prices and passing those costs on to homeowners and commercial buyers.
For HVAC contractors, the levers that protect margin when the cost side of the business is fixed in someone else’s boardroom are the same as they have always been: cleaner lead quality, faster response times, and a pipeline that runs without leaks.
