DHI Corp (DHI) is a company that offers for sale fans and dehumidifiers and plumbing products based in Mequon, Wisconsin. DHI sold or offered for sale showerheads, tub spout diverters, kitchen faucets, lavatory faucets, and ceiling fans in California, from September 2019 to September 2023.

This case was the result of an investigation performed by California Energy Commission (CEC) staff. CEC’s investigation and testing process identified that DHI was offering for sale Design House brand showerheads, tub spout diverters, kitchen faucets, lavatory faucets, and ceiling fans that were not certified to the Modernized Appliance Efficiency Database System (MAEDbS).

To resolve this matter, DHI executed a Settlement Agreement with CEC on June 26, 2025, for $45,000.00. The penalty monies are deposited into the Appliance Efficiency Enforcement Subaccount as required in Public Resources Code section 25402.11. DHI has also agreed to a compliance plan to test and certify all models to MAEDbS before continuing to sell in California.
