Published Specifications
Failure to be listed in the NRCan Searchable Product List
In Canada, all air-conditioning and heat-pump systems must be listed in the NRCan database. In fact, it is illegal to import or sell a unit that is not listed. At the time of this publication, March 16, 2026, the Exinda HPERV is not listed in the NRCan Searchable Product List.
Failure to meet NRCan Minimum Efficiency Requirements
Guangdong Exinda Technology manufactures the Exinda HPERV in China, with specifications claiming 11,000 BTU and a 10.75 EER. The Exinda HPERV only lists an EER and a COP. Neither EER nor COP is a legal rating for this product category. For a heat pump, federal law requires SEER2 and HSPF2. Under federal law (Energy Efficiency Regulations, 2016, and AHRI 210/240), any 11,000-BTU heat pump in this class must meet a minimum SEER2 rating of 13.4 to be legally sold, installed, or used in Canada. This alone renders the units illegal.
Illegal Misclassification
By using an EER instead of SEER2, Exinda is classifying the HPERV as PTHP, but HPERV does not meet the PTHP definition under Energy Efficiency Regulations.
The Exinda HPERV unit lacks these traits. Misclassifying the Exinda HPERV as a PTHP by using EER is a direct violation of NRCan rules and is illegal.
Fraudulent and Fake Numbers
Exinda HPERV is not capable of delivering 11,000 BTUs of cooling at 10.75 EER (Exinda incorrectly lists this as an EER of 3.15) or 14,000 BTUs of heating at 3.72 COP. Most importantly, Exinda’s own numbers don’t add up. 14,000 BTU of heating is 4,103 W of heat; divided by 1,300 W of power, it’s 3.16 COP, not the 3.72 they incorrectly show. While these metrics are not relevant to this unit, the numbers cannot be obtained. There is no way the Exinda HPERV will use only 1,160 watts to produce 11,000 BTU of cooling, or 1,300 watts to produce a whopping 14,000 BTU of heating. With heat pumps, the heating and cooling outputs are similar because one is simply the reverse of the other. Exinda wants you to believe that the same unit can produce 32% more heat than cool, and at a 17.5% higher efficiency. Ask any first-year engineering student if a heat pump can have a 55% better performance in heating than cooling.
Regulatory Violation Summary
Exinda — HPERV
This product is illegal to distribute, specify, install, or use in the United States and Canada.
Exinda’s published efficiency numbers are fabricated, mathematically impossible, and use two separate illegal rating metrics — publishing EER instead of SEER2 and COP instead of HSPF2 — neither of which has been legally acceptable since January 1, 2023. The HPERV fails to meet DOE and NRCan minimum efficiency requirements under every applicable classification.
One Million Dollar Guarantee
We back the statement that the Exinda HPERV cannot legally be sold, installed, or used in the United States and Canada with a One Million Dollar Guarantee.
Minimum Efficiency Requirements Not Met
These ratings cannot simply be invented. They must be established through testing in a genuine laboratory under correct DOE and NRCan test procedures. Exinda has not done this, and the data it publishes makes clear why.
Illegal Rating Metrics Uses
Publishing two separate retired and inapplicable metrics is not a technicality or an oversight. EER and COP were both replaced by mandatory legal requirements in 2023. Their continued use constitutes a deliberate misrepresentation of compliance status to customers, dealers, and regulators.
