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 Zymbo Dolphin 40 cannot be found in the NRCan Searchable Product List or in the DOE CCMS Database.
Failure to Meet NRCan Minimum Efficiency Requirements
Zymbo is the manufacturer of Dolphin 40, which it produces for Kinghome, Silktech, and other brands. Zymbo claims the Dolphin 40 has a nominal cooling capacity of 12,000 BTU. Under federal law (Energy Efficiency Regulations, 2016, and AHRI 210/240), any 12,000-BTU heat pump in this class must meet a SEER2 rating of 13.4 to be legally sold, installed, or used in Canada. Zymbo does not publish a SEER2 value because the unit cannot meet the required 13.4 SEER2 when tested in a certified lab. This alone renders the units illegal.
Illegal Rating
Zymbo uses the wrong rating metric: EER instead of SEER2, COP instead of HSPF2. Zymbo publishes only an EER for cooling and a COP for heating. Neither EER nor COP is a legal rating for this product category. For a heat pump, federal law requires SEER2 and HSPF2, and it is rated under AHRI 210/240. Zymbo deliberately avoids publishing SEER2 because the unit would fail. This alone renders the units illegal.
Illegal Misclassification
By using an EER instead of SEER2, Kinghome is classifying Dolphin 40 as a PTHP, but Zymbo Dolphin 40 does not meet the PTHP definition under Energy Efficiency Regulations. A lawful PTHP must have a wall sleeve, a separate unencased chassis, and through-the-wall mounting. Zymbo Dolphin 40 units lack these traits. Misclassifying the Dolphin 40 as PTHP by using EER is a direct violation of NRCan rules and is illegal.
Miscalculated Performance Numbers
Zymbo misrepresents even the numbers it publishes for Dolphin 40 for both heating and cooling.
In Cooling
Using their own watt input: 12,000 ÷ 1,209 = EER 9.93. Yet, Zymbo publishes 10.5 EER. The cooling capacity is fraudulently listed as 12,000 BTU with an EER of 10.5. When calculating the numbers, the EER2 is really 9.93, which is illegal.
In Heating
Using their own watt input: 11,970 ÷ 3.412 (BTU to W) ÷ 947 = COP 3.7. Yet, Zymbo publishes 3.5 COP. They publish a higher COP than the math! It is possible that the originally reported figures seemed unrealistic, so instead of adjusting the data to yield a mathematically plausible COP, they simply listed a lower COP. Fraudulently manufacturing testing data is illegal.
Fraudulent and Fake Numbers
The 12,000-BTU capacity they claim, along with the 10.5 EER rating, is fake and fraudulent. When tested in a lab, this unit will not produce 12,000 BTU and a 10.5 EER. So, even ignoring the misclassification and wrong ratings, the actual numbers they claim are fake.
Regulatory Violation Summary
Zymbo — Dolphin 40
This product is illegal to distribute, specify, install, or use in the United States and Canada. Zymbo’s published efficiency numbers are fabricated, mathematically impossible, and use illegal EER rating metrics instead of the legally required SEER2 or CEER metrics that have not been legally acceptable since January 1, 2023. The Dolphin 40 fails to meet DOE and NRCan minimum efficiency requirements under every applicable classification.
One Million Dollar Guarantee
We back the statement that the Zymbo Dolphin 40 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. Zymbo has not done this, and the data it publishes makes clear why.
Illegal Rating Metrics Used
Publishing a retired and inapplicable metric is not a technicality or an oversight. EER was replaced by mandatory legal requirements in 2023. Its continued use constitutes a deliberate misrepresentation of compliance status to customers, dealers, and regulators.
