HARDI Flags Potentially Illegal HVAC Products in Channel

A trade group representing HVAC equipment distributors, HARDI, is warning that some air conditioning equipment on the market may not meet federal rules. The concern centers on outdoor condensing units using R-410A, an older refrigerant being phased out for new systems. Units made in 2025 or 2026 can still legally be sold to repair an existing system, but they cannot be used to replace a whole system, and they're supposed to meet U.S. Department of Energy efficiency standards and carry a "for servicing only" label. HARDI says some units showing up from unfamiliar brands and sellers may not actually follow these rules.

For a homeowner, this mostly matters if you're getting central air or a heat pump installed and want to make sure the equipment is legitimate. Warning signs include a brand or model not listed in government or certification databases, missing or unverifiable safety certifications (such as UL or Intertek ETL marks), a model number that doesn't match official records, or a refrigerant unit marketed for new installation without the required service-only label. Another red flag: any unit claimed to work safely with multiple refrigerants that belong to different safety classes, since that would violate safety standards.

HARDI has set up a reporting system so its distributor members can flag suspicious equipment for investigation by the DOE or EPA. The issue is mainly playing out at the distributor level, but it's worth knowing about if you're planning a cooling system purchase soon and want to ask questions about where the equipment came from and whether it's properly certified.
