Dubbll DDHPA-10X-00E and DDHPA-12Y-10E are Illegal and Non-Compliant

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. It is illegal to import or sell a unit that is not listed. At the time of this publication, March 16, 2026, neither the Dubbll DDHPA-10X-00E nor the DDHPA-12Y-10E can be located in the NRCan Searchable Product List under any product category — not as a Room Air Conditioner, not as a Heat Pump, and not even as a PTHP.

Failure to Meet NRCan Minimum Efficiency Requirements

Dubbll DDHPA-10X-00E and DDHPA-12Y-10E both have a claimed nominal cooling capacity of 10,000 BTU and a claimed heating capacity of 9,000 BTU. Under federal law, any unit in this class must meet one of the following minimum efficiency thresholds to be legally sold, installed, or used in Canada:

• 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)

Dubbll publishes a claimed 17 SEER2, which would appear compliant on its face. However, as demonstrated below, that number is mathematically impossible for this hardware and is not supported by any certified laboratory test. A fake SEER2 rating does not constitute compliance — it constitutes fraud.

Fraudulent and Fake Numbers

Dubbl's published specifications are internally contradictory in both cooling and heating and directly conflict with the data published by Nordica, the manufacturer of the underlying hardware.

In Cooling: Dubbll publishes three separate cooling efficiency figures for the same unit: a 17 SEER2, a 12.26 CEER, and a 9.9 EER2. These three numbers cannot simultaneously describe the same piece of equipment. CEER is always lower than EER because it accounts for standby power consumption in addition to active consumption. A CEER of 12.26, which is 24% higher than the published EER2 of 9.9, is a physical impossibility. Either the CEER is wrong, the EER2 is wrong, or both are wrong. In this case, both are wrong.

Nordica, the manufacturer, publishes the following for the same hardware:

• 115V model (YWD-10HD/FC6-W):
• Cooling Capacity: 10,000 BTU
• Power Input: 1,080 W

10,000 ÷ 1,080 = EER 9.26. Yet Nordica publishes 9.9 EER2 — already inflated beyond what its own wattage supports.

• 208/230V model (YWD-10HD2/FC6-W):
• Cooling Capacity: 10,000 BTU
• Power Input: 1,020 W

10,000 ÷ 1,020 = EER 9.80. Yet Nordica also publishes 9.9 EER2 for this model — marginally inflated but still inconsistent.

Dubbll, using the same hardware, claims a power input of only 970W — 110W less than Nordica's 115V model and 50W less than Nordica's 230V model for identical cooling output. No hardware modification has been made. There is no engineering basis for a rebranded unit to consume less power than the manufacturer specifies. The reduced wattage is fabricated. Using Dubbll's own published figures:

10,000 ÷ 970 = EER 10.31. Yet Dubbll publishes a 9.9 EER2 — lower than what its own math produces — and simultaneously claims a 12.26 CEER that is higher than any EER figure in the dataset. None of these numbers is consistent with the others, with the manufacturer's data, or with the laws of physics. The claimed 17 SEER2 is the most egregious figure. Nordica publishes a fake 16 SEER2 for this same platform, which is itself impossible.

Dubbll adds another point on top of the manufacturer's already-fabricated ceiling, without any hardware difference to justify it. A rebranded unit cannot outperform the manufacturer's own product on identical hardware. The 17 SEER2 was invented.

In Heating: Nordica publishes the following for the same hardware:

• 115V model:
• Heating Capacity: 9,000 BTU
• Power Input: 930 W

9,000 ÷ 3.412 ÷ 930 = COP 2.84. Yet Nordica publishes a COP2 of 3.10 — inflated beyond what its own figures support.

• 208/230V model:
• Heating Capacity: 9,000 BTU
• Power Input: 850 W

9,000 ÷ 3.412 ÷ 850 = COP 3.10. Yet Nordica publishes a COP2 of 3.40 — again inflated.

Dubbll claims the same 9,000 BTU heating output at only 818W — less power than either Nordica model requires for the same output.

Using Dubbll's own figures: 9,000 ÷ 3.412 ÷ 818 = COP 3.22. Dubbll publishes a COP of 3.23, which is at least internally consistent with its own wattage. However, the wattage itself is fabricated — lower than the manufacturer's specification for the same hardware, with no engineering justification. A consistent set of fake numbers is still fake.

Dubbll also publishes an HSPF2 of 7.5, matching Nordica's claimed HSPF2 exactly, despite claiming lower power consumption. If Dubbll's unit genuinely used less power than Nordica's, its HSPF2 would be higher than Nordica's, not identical to it. The matching HSPF2 confirms that Dubbll simply copied Nordica's number without adjusting it to reflect its own claimed wattage — another sign that none of these figures originate from real laboratory testing.

Illegal Rating Metrics

Dubbll publishes a CEER alongside an EER2 and a SEER2 for the same unit. CEER is the correct metric for Room Air Conditioners. SEER2 and HSPF2 are the correct metrics for Heat Pumps. Publishing both simultaneously implies the unit is being classified as both product categories at once, which is not permissible under the Energy Efficiency Regulations, 2016. A product must be classified as one or the other, tested under the applicable procedure, and rated accordingly.

The simultaneous publication of CEER and SEER2 — both of which are fabricated — suggests that Dubbll is attempting to appear compliant under whichever standard a reviewer applies, without having tested the unit under either.

Illegal Misclassification

The Dubbll DDHPA-10X-00E and DDHPA-12Y-10E do not meet the structural definition of a PTHP under the Energy Efficiency Regulations, 2016. A lawful PTHP must consist of a wall sleeve and a separate unencased chassis designed for through-the-wall installation. These units lack all of these features and cannot be lawfully classified as PTHPs. They must be classified as either a Room Air Conditioner or a Heat Pump. Under both classifications, the published efficiency figures are fabricated, and the units fail to meet mandatory minimum requirements.

Regulatory Violation Summary: Dubbll DDHPA-10X-00E and DDHPA-12Y-10E

These products are illegal to distribute, specify, install, or use in Canada.

Dubbll's published efficiency figures — a 17 SEER2, a 12.26 CEER, and a 9.9 EER2 — are mutually contradictory, inconsistent with the manufacturer's own data for identical hardware, and impossible to replicate under certified laboratory conditions. The DDHPA-10X-00E and DDHPA-12Y-10E use identical hardware to the Nordica YWD-10HD/FC6-W and YWD-10HD2/FC6-W, products whose published specifications have been independently verified as fabricated.

These ratings cannot be invented. They must be established through testing at an SCC-accredited laboratory in accordance with the correct NRCan test procedures. Dubbll's own published data disproves its own published ratings.
