The HVAC industry in the United States is governed by strict federal regulations, specifically those set by the Department of Energy (DOE). Following a recent update to DOE testing standards, all heat pumps sold or installed in the country must meet specific efficiency metrics. Concerns have been raised regarding the Zymbo Heat Pump and its published data. The published performance data is inaccurate and misleading. These issues raise serious questions about the product's compliance, testing methods, and legal classification. 

Use of Non-Compliant Rating Metrics

The ClimaPuro System lists efficiency using EER (Energy Efficiency Ratio) for cooling and COP (Coefficient of Performance) for heating. While both these metrics can provide technical insight, they are not the legally required standards for this product category. Federal law requires that the heat pump must be rated using SEER2 (Seasonal Efficiency Ratio 2) and HSPF2 (Heating Seasonal Performance Factor 2), based on AHRI 210/240 testing procedures. The absence of these required ratings shows potential non-compliance with DOE rules.

Failure to Meet Minimum Efficiency Requirements

According to product materials, the Zymbo heat pump has a cooling capacity of 8,831 BTU. Under federal law (10 C.F.R. Part 430), units with this capacity must achieve a minimum SEER2 rating of 13.4 to be legally marketed and installed in the U.S. However, no certified SEER2 rating has been provided. Without this documentation, the product cannot be verified as meeting the mandatory efficiency limit. 

Inconsistent and Questionable Performance Data

The published performance data is inconsistent and inaccurate. ClimaPuro lists a cooling capacity of 8,831 BTU with a 750-watt input, which calculates to an EER of approximately 11.77. However, the promotional material and brochure show an EER of 10.6. Similar inconsistencies appear in the heating data, making the product noncompliant and illegal to sell and install in the United States. 

Conclusion

These issues clearly show that the ClimaPuro system does not meet U.S. HVAC regulatory standards. The lack of certified SEER2 and HSPF2 ratings, reliance on non-compliant metrics, and inconsistent performance data point to potential violations. This could result in regulatory penalties, product removal, and financial consequences for both sellers and buyers. Additionally, consumers may face higher energy costs if the system fails to perform as advertised.
