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 Kinghome Dolphin 40 cannot be located in the NRCan Searchable Product List.
Failure to meet NRCan Minimum Efficiency Requirements
Kinghome Dolphin 40 manufactured by Zymbo. It is the same model that Zymbo sells directly as the Zymbo Dolphin 40. It is worth noting that, unlike the other brands, Kinghome appears to use the exact specifications supplied by Zymbo without altering any published values. Unfortunately for Kinghome, they rely on Zymbo, a cheap knockoff manufacturer that, in addition to manufacturing heat pumps, also manufactures the specifications.
Kinghome claims the Dolphin 40 has a nominal cooling capacity of 12,000 BTU. Under federal law (Energy Efficiency Regulations, 2016 + AHRI 210/240), any 12,000-BTU heat pump in this class must meet a minimum SEER2 rating of 13.4 to be legally sold, installed, or used in Canada. Kinghome 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
Kinghome uses the wrong rating metric: EER instead of SEER2, COP instead of HSPF2. Kinghome 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:
Kinghome simply copied the specs from their fake spec manufacturer, Zymbo, which deliberately avoids publishing SEER2 because the unit would fail to meet it. This alone renders the units illegal.
Illegal Misclassification
By using an EER instead of SEER2, Kinghome is classifying Dolphin 40 as a PTHP, but Kinghome 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.
Kinghome 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
Kinghome misrepresents even the fake numbers it publishes for Dolphin 40 in both heating and cooling. Kinghome simply copies the numbers it received from Zymbo. They should have at least checked the math…
Using their own watt input: 12,000 ÷ 1,209 = EER 9.93. Yet, Kinghome publishes 10.5 EER. Fraudulently lists the cooling capacity as 12,000 BTU with an EER of 10.5. When calculating the numbers, the EER2 is really 9.93, which is illegal.
Using their own watt input: 11,970 ÷ 3.412 (BTU to W) ÷ 947 = COP 3.7. Yet, Kinghome publishes 3.5 COP. They publish a higher COP than the math! Perhaps the fake numbers looked too good, so instead of raising the power input to create a more realistic-looking fake COP, they just 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 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
Kinghome — Dolphin 40
This product is illegal to distribute, specify, install, or use in the United States and Canada. Kinghome’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 Kinghome 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. Kinghome has not done this, and the data it publishes makes clear why.
Illegal Rating Metrics Uses
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.
