A proposed class action lawsuit claims that Midea America Corp. sold and then failed to adequately recall defective U-shaped and U-shaped inverter window air conditioners that, unbeknownst to consumers, were susceptible to mold buildup.

According to the 19-page lawsuit, approximately 1.7 million window air conditioners sold under the brand names Midea, Comfort Aire, Danby, Frigidaire, Insignia, Keystone, LBG Products, Mr. Cool, Perfect Aire and Sea Breeze were advertised, sold and installed with no adequate warning of the apparent defect that can cause excessive moisture accumulation or the subsequent buildup of mold.

According to the U.S. Consumer Product Safety Commission (CPSC), the problem with the Midea U and U+ window air conditioners, which were recalled on June 5, 2025, stems from the fact that pooled water in the products can fail to drain quickly enough, causing mold growth.

Mold exposure is a known health hazard linked to various allergic reactions, respiratory and pulmonary risks and conditions such as wheezing, asthma exacerbation and hypersensitivity pneumonitis, the case points out.

Additionally, HVAC systems such as air conditioners are known as common sources of indoor mold growth, often due to excess or undrained condensation in poorly designed or defective systems, the filing mentions. Per the suit, indoor mold contamination can be expensive to identify and remove, sometimes costing more than $10,000.

According to the case, Midea received at least 152 reports of mold accumulation in the air conditioners and 17 reports of users having experienced mold-exposure symptoms, including allergic reactions, respiratory infections, sneezing, sore throats and coughing.

The class action lawsuit charges that Midea’s recall of the U and U+ window air conditioners was insufficient given that consumers were not offered money for mold testing, cleaning or replacement of the products. Though consumers were offered a pro-rated refund, replacements and free repairs through the recall, the filing contends that the measure is inadequate given that a defective, mold-susceptible product has no value.

The recalled products, which were sold at various online and brick-and-mortar retailers between March 2020 and May 2025, include the following window air conditioners bearing certain model numbers:
