Mits Air MITSWZ-28EC
is Illegal and Non-Compliant
Innova’s Million Dollar Challenge
How Mits Air is Cheating
Overview
The Mits Air MITSWZ-28EC is a residential mini-split unit marketed in Canada with a claimed nominal cooling capacity of 8,881 BTU and a claimed heating capacity of 7,895 BTU. A review of its published specifications and regulatory standing reveals multiple serious compliance failures under Canadian federal law, as well as technical inconsistencies that undermine the credibility of the manufacturer’s published data.
Failure to be listed in the NRCan Searchable Product List
Under Canadian federal regulations, all air-conditioning and heat-pump systems must be listed in Natural Resources Canada’s (NRCan) Searchable Product List before they can be legally imported, distributed, or sold. As of the date of this publication, the MITSWZ-28EC does not appear in that database under any applicable product category — including Room Air Conditioner, Heat Pump, or Packaged Terminal Heat Pump (PTHP).
This absence alone constitutes a violation of federal law, independent of any other deficiency identified in this analysis.
Failure to Meet NRCan Minimum Efficiency Requirements
Canadian federal regulations establish minimum efficiency thresholds for units in this capacity class. Depending on classification, the MITSWZ-28EC would be required to meet one of the following:
- As a Heat Pump: 13.4 SEER2 for cooling and 5.4 HSPF2 for heating
- As a Room Air Conditioner: 9.3 CEER (rising to 13.7 CEER effective May 26, 2026)
Mits Air publishes neither a SEER2 nor a CEER for cooling, and no HSPF2 for heating. Instead, the company publishes EER and COP values — metrics that do not satisfy Canadian regulatory requirements and cannot be used as substitutes for the mandated ratings. The absence of any compliant efficiency rating renders the unit illegal to sell, install, or use in Canada, regardless of its actual performance.
The Zymbo Connection
The MITSWZ-28EC is manufactured by Zymbo, which markets the identical unit as the WZ-28EC. The two products share the same compressor, coil geometry, refrigerant charge, airflow path, and chassis. The only distinguishing feature is the nameplate.
A direct comparison of the published specifications from both companies reveals figures that are physically inconsistent:
Let’s compare the data from the manufactuer, Zymbo to Mits Air:
This doesn’t add up.
Cooling: An Implausible Efficiency Gain
Mits Air’s figures show a 9.4% reduction in input power while cooling capacity falls by only 1.3% — producing an apparent 8.9% improvement in EER. On identical hardware with identical refrigerant, this is not physically achievable. A reduction in input power of that magnitude would require a corresponding reduction in capacity, not a trivial one.
Heating: An Implausible Efficiency Loss
The heating figures are even more inconsistent. Mits Air reports a 19.7% reduction in heating capacity compared to Zymbo, while input power is reduced by only 1.1% — and COP actually declines by 4.0%. Thermodynamically, a substantial reduction in output capacity on the same hardware, with nearly unchanged power consumption, is not possible. Furthermore, lower capacity at similar power input should generally produce higher efficiency, not lower. The direction and magnitude of these changes are irreconcilable with the laws of thermodynamics.
The only coherent explanation is that Mits Air’s published figures were not derived from laboratory testing. They appear to have been manually entered without a credible empirical basis.
Regulatory Classification and Labelling Violations
Because the MITSWZ-28EC carries no recognized efficiency rating — no CEER, no SEER2, no HSPF2 — it cannot satisfy the classification or labelling requirements under any applicable NRCan product category. To achieve legal status, the unit would require:
- As a Heat Pump: A certified SEER2 of at least 13.4 and a certified HSPF2 of at least 5.4, established through testing at a Standards Council of Canada (SCC)-accredited laboratory.
- As a Room Air Conditioner: A certified CEER of at least 9.3, rising to 13.7 after May 26, 2026, established through the same accredited process.
These ratings cannot be self-declared or calculated from published wattage figures. They must be derived from standardized test procedures conducted at an accredited facility
Summary of Violations
Mits Air MITSWZ-28EC:
- Not listed in the NRCan Searchable Product List
- No compliant efficiency rating published (no CEER, SEER2, or HSPF2)
- Published EER and COP figures are inconsistent with the specifications of the identical Zymbo WZ-28EC and cannot be reconciled with thermodynamic principles
- Fails to meet NRCan product classification and labelling requirements
- No evidence of testing at an SCC-accredited laboratory
- Potential violation of the Competition Act through false or misleading performance representations
Mits Air MITSWZ-28EC cannot legally be sold, installed, or used in Canada, and we back that statement with a $1,000,000 Guarantee.
Illegal to Distribute, Install, and Use
The Mits Air MITSWZ-28EC cannot legally be distributed, specified, installed, or used in Canada. It is absent from the NRCan product registry, carries no required efficiency ratings, and its published technical data contains internal contradictions that are not consistent with laboratory-derived measurements. Contractors, specifiers, and consumers should be aware that sourcing, installing, or using this unit may expose them to regulatory and legal liability. In addition to the regulatory violations above, the publication of efficiency and capacity figures that contradict those of the unit’s own manufacturer — and that are inconsistent with physical reality — may constitute false or misleading representations under the Competition Act (R.S.C., 1985, c. C-34), which prohibits deceptive claims in the promotion of products, including the material omission of required performance data.
How Everyone Gets Hurt
Sellers
Private labelers, Manufacturers,
Distributors, Dealers, Resellers
Selling a non-compliant HVAC product is a direct violation of the Energy Efficiency Act and NRCan regulations. Sellers are exposed to:
Federal Civil Penalties
NRCan may prosecute for non-compliance for every unit distributed in commerce. Penalties stack and can reach six-figure outcomes per model.
Product Seizure and Forced Recall
NRCan can seize inventory, block further distribution, and mandate recall or destruction of illegal equipment.
Competition Bureau enforcement… Competition Act Section 52
Publishing fabricated ratings constitutes a deceptive trade practice under the Competition Act. This exposes the seller to federal enforcement, mandatory corrective advertising, and civil penalties.
Breach of Contract and Indemnification Claims
Developers, contractors, and property owners can sue the seller for damages if the installed equipment fails inspection, fails commissioning, or causes code violations.
Class-Action Exposure
Tenants, condominium associations, and homeowners’ groups can sue for misrepresentation, damages, inflation in energy costs, or unsafe equipment.
Loss of Manufacturer and Distributor Licenses
OEM partnerships and distribution channels can be terminated for selling illegal equipment.
Selling these units is both legally and financially dangerous.
Installers
Contractors, HVAC technicians, MEP firms
Installing non-compliant equipment exposes the installer to direct professional and legal risk.
Violation of state and local mechanical codes
Most jurisdictions require installed equipment to be listed, certified, and compliant with NRCan minimums. Installing unlisted units violates the code.

Any engineer who signs off on these units is accepting personal liability.
Building Owners
Developers, Property managers, REITs, Condo associations
Owning a building with illegal HVAC equipment exposes the owner to substantial financial and legal risks.
Code violations and failed inspections
Buildings containing non-certified equipment can fail Local Authority inspections.
Forced removal and replacement
Authorities can mandate the removal of every installed unit, at the owner’s expense.
Insurance cancellation or claim denial
If the equipment is not legal or not NRCan-compliant, insurers may deny coverage or void property insurance policies.
Reduced property value
Buildings with illegal equipment face valuation reductions, impaired financing, and lender objections.
Tenant lawsuits and warranty claims
Tenants can sue for non-performance, high heating/cooling costs.
Fines and enforcement actions
Owners can be fined for every illegal unit installed or operated within the building.
Owning or operating these units exposes the property to material legal and financial damage.
End-Users
Residents, Tenants, Homeowners
Even the resident or end-user is exposed to risk when using non-compliant equipment.
High energy bills and poor performance
Because the published performance data is fake, real-world operating costs are substantially higher than the claimed ratings suggest.
End-users bear financial burdens due to equipment that consumes more power and has limits.
