Violation of Federal And Provincial or State Mechanical Codes
In Canada, every province requires that installed HVAC equipment meet NRCan energy-efficiency standards and carry an SCC-accredited verification mark. Installing a product not on the NRCan Searchable Product List violates both the federal Energy Efficiency Act and the provincial building codes, which require NRCan compliance. In the United States, most jurisdictions require installed equipment to be listed, certified, and compliant with DOE minimum efficiency standards under applicable state and local mechanical codes. Installing unlisted, uncertified units violates those codes in every jurisdiction where these products have been sold and installed.
The Regulatory Databases are Public. Checking Them is a Basic Professional Obligation
The NRCan Searchable Product List and the DOE CCMS database are both publicly available, free to access, and searchable in seconds. A contractor who installs equipment without verifying its listing status in the applicable regulatory database has failed the most basic due diligence step required by their professional obligations. A contractor who checks, finds no listing, and proceeds anyway has done something knowingly. In either case, the professional and legal consequences are the same, and the database’s availability as a public resource means the defense of ignorance is unavailable.

Loss of Contractor License
In Canada, every province requires HVAC technicians to hold a Certificate of Qualification or an equivalent provincial trade credential to legally perform refrigeration and air conditioning work. Provincial licensing boards can suspend or revoke that credential for the systematic installation of non-certified, illegally rated equipment. In the United States, state contractor licensing boards have equivalent authority. For a contractor whose entire livelihood depends on their trade qualification, suspension or revocation is career-ending.

Civil Liability and Class Action Exposure
If a non-compliant unit fails, performs below its fabricated specifications, overloads electrical circuits, leaks refrigerant, causes mold or structural damage due to inadequate heating, or causes any other harm, the installer faces civil liability for the full extent of resulting damages in US and Canada. Beyond individual claims, contractors who have installed these units across multiple residential buildings face the possibility of being named as defendants in class actions brought by residents of those buildings — either directly, or as third-party defendants added by building owners seeking contribution for their own class action exposure. The contractor who installed illegal equipment into a building where a class of residents has suffered documented financial harm cannot claim ignorance of the product’s non-compliance when the NRCan database was publicly available throughout the installation period.

Professional Negligence Claims
Installing non-certified, non-listed equipment is a breach of the standard of care expected of a qualified HVAC professional in both Canada and the United States. Civil claims for professional negligence are available to building owners and property managers who suffer losses attributable to installations that did not meet applicable legal standards — and those claims can be brought individually or as part of class proceedings where multiple buildings and multiple owners share the same harm arising from the same contractor’s systematic installation of non-compliant equipment.

Insurance Denial
Contractor liability insurance in both Canada and the United States typically covers work performed on compliant, code-approved equipment. Work performed on federally non-compliant equipment gives the insurer legitimate grounds to dispute or deny coverage when a claim arises. An insurer presented a claim for a heat pump that was illegal to sell in Canada or the United States and has a well-documented basis for declining coverage entirely — leaving the contractor personally exposed for the full extent of any damages, including their share of any class-action judgment or settlement.
Installers who choose these units assume direct, personal, and potentially career-ending legal and financial responsibility in US and Canada.
