A Faulty Drain. 1.7 Million Homes. Five Years of Silence.

Between March 2020 and May 2025, Midea America Corp. sold approximately 1.7 million U-shaped and U-shaped inverter window air conditioners across the United States. These units moved through the shelves of Costco, Home Depot, Best Buy, Menards, Walmart, Lowe’s, and BJ’s Wholesale, as well as online marketplaces including Amazon.com. Prices ranged from $280 to $500 (the cost of a week of groceries for a family of four, paid by families who expected to breathe cleaner air, not worse air).

The units were sold under a web of brand names: Midea, Frigidaire, Insignia, Keystone, Mr. Cool, Perfect Aire, Comfort Aire, Sea Breeze, Danby, and LBG Products. The same defective design ran through all of them. A faulty drain plug caused moisture to accumulate on the evaporator coils inside the unit.

When water pools in a dark, warm, enclosed space, mold follows. When the air conditioner runs, it pushes air across those mold-colonized coils and into the living room, the bedroom, the nursery. The unit that was supposed to keep the summer heat out was importing a biological hazard and dispersing it as cool air.

The Recall Arrived Five Years Too Late

On June 5, 2025, the U.S. Consumer Product Safety Commission issued Recall No. 25-320. The recall acknowledged the mold risk and instructed consumers to contact Midea for a free repair, a replacement drain plug, or a refund. The refund itself was described as either “full or prorated” depending on when the unit was purchased. A prorated refund on a product that grew mold in your home is an insult dressed up as a remedy.

The recall did not offer a single dollar for professional mold testing. It did not offer a single dollar for mold remediation. It did not help consumers figure out whether the mold had already spread from the unit into their walls, their carpets, their HVAC ductwork, or their children’s bedroom ceiling. Midea’s solution was: return the machine. The contamination it left behind? That’s your problem.

The Damage Midea Won’t Put a Dollar Sign On

Mold is invisible. That is the entire problem with it, and Midea knows this better than anyone. You cannot see it colonizing the back of your drywall. You cannot see it threading through the insulation behind your bedroom wall. You cannot see it settling into the carpet fibers your toddler crawls on every morning. By the time mold announces itself with a smell, a stain, or a symptom, it has already been there for weeks or months, reproducing quietly while the air conditioner that seeded it kept running on your power bill.

According to the CDC, inhaling mold spores causes coughing, wheezing, exacerbation of asthma, and a condition called hypersensitivity pneumonitis, which is an inflammation of the lungs triggered by repeated exposure to an allergen. These are conditions that land people in urgent care clinics. These are conditions that keep children home from school. These are conditions that send elderly people to the emergency room. The lawsuit documents seventeen confirmed cases of consumers experiencing respiratory infections, allergic reactions, coughing, sneezing, and sore throats directly attributed to mold exposure from these units. Seventeen people who reported it. The number who suffered without ever connecting their symptoms to a faulty drain plug inside their AC unit is unknowable.

Think about what it means to discover mold in your home. The panic. The googling at 2 a.m. The phone calls to landlords or contractors who tell you that air sampling alone can cost several hundred dollars before a single remediation professional has touched anything. The complaint documents that professional mold testing runs between $200 and $1,000 (the equivalent of one to three months of a low-wage worker’s utility bills) just to confirm what you already suspect. Then the remediation quote arrives: negative air pressure barriers, HEPA scrubbers, demolition of contaminated drywall and insulation, antimicrobial treatment. The national average remediation cost is $2,500 to $6,000 (enough to wipe out the emergency savings of the majority of American households). In severe cases, where mold has colonized HVAC systems or structural elements, costs exceed $30,000 (more than half a year’s income for a median American worker). Midea’s recall covers none of this. Not a dollar. Not a referral. Not even an acknowledgment that the problem might have spread beyond the machine.

The betrayal runs deeper than money. These households purchased an appliance in good faith, from brand names they recognized at stores they trusted. Frigidaire is a household name. Keystone. Insignia. Best Buy’s store brand. People saw those names on the box and reasonably assumed that someone had checked the product was safe. The complaint makes clear that Midea possessed “superior knowledge regarding the risks involved in the production and manufacturing of its Products.” The company designed the thing. The company tested the thing. The company watched the mold reports come in. And the company said nothing on the box, nothing at the point of sale, nothing in the instruction manual, nothing at all, for five years. The decision to stay silent was not an oversight. Silence was the business strategy.

The Recall Itself Is a Second Betrayal

Even the remedy Midea offered is constructed to minimize corporate exposure rather than maximize consumer protection. The refund option is described as “prorated” based on purchase date or date of manufacture. That means someone who bought a unit in 2020 and ran it through five summers of mold dispersion into their home gets back a fraction of the purchase price, not the full amount, and nothing for the damage the unit caused. The lawsuit argues this plainly: “a product which fosters the development of mold has no value.” The prorated framing treats a defective mold machine as though it had some legitimate useful life that the consumer benefited from. It did not. Every hour it ran, it potentially made the home less safe.

For consumers who want a repair rather than a refund, Midea instructs them to keep using the unit while waiting for a technician or a repair kit, directing them to a website for inspection instructions. This means Midea’s own recall protocol accepts the possibility that 1.7 million defective mold-generating machines continue operating in homes during the weeks or months it takes to process repairs. The lawsuit explicitly notes: “there is no evidence that the offered remedy will actually solve the defect.” Midea is asking consumers to trust the same company that hid this problem for five years to now competently fix it.

What the Lawsuit Says, Word for Word

These are direct citations from the class action complaint filed June 9, 2025. Read them slowly.

“Defendant designed, manufactured, and tested the Products and was aware that they contained a defect, which allowed water to pool within the Products due to a faulty drain value. Not only was Defendant aware of the defect through its design, manufacturing, and testing, they received consumer complaints and warranty requests regarding the nature of the defect. Defendant was aware of at least 152 reports of mold in the air conditioners, including 17 reports of consumers experiencing symptoms such as respiratory infections, allergic reactions, coughing, sneezing and/or sore throats from mold exposure. However, none of this information was publicly available.”

— Complaint ¶ 28, Catalano v. Midea America Corp.

“Defendant’s failure to disclose this defect at the time of sale — and its refusal to assume responsibility for resulting contamination — constitutes consumer deception and unjust enrichment. Plaintiff and Class Members would not have purchased the units or would have paid significantly less had they known of the contamination risk and limited recourse available.”

— Complaint ¶ 11, Catalano v. Midea America Corp.

“Defendant made the untrue and/or misleading statements and omissions willfully, wantonly, and with reckless disregard for the truth.”

— Complaint ¶ 62, Catalano v. Midea America Corp.

“The provision of a potential ‘prorated refund’ is wholly inadequate as a product which fosters the development of mold has no value.”

— Complaint ¶ 9, Catalano v. Midea America Corp.

“In making the false, misleading, and deceptive omissions described herein, Defendant knew and intended that consumers would pay a premium for Products marketed without the likelihood of causing mold growth over comparable products not so marketed.”

— Complaint ¶ 36, Catalano v. Midea America Corp.

“Plaintiff and the New York Subclass Members received less than what they bargained and paid for… the Products they purchased were mislabeled, unhealthy, and entirely worthless.”

— Complaint ¶ 71, Catalano v. Midea America Corp.

Who Gets Hurt and How

Public Health: Breathing Is Now a Hazard

The CDC documentation cited in this lawsuit is not ambiguous. Mold spore inhalation causes coughing, wheezing, asthma exacerbation, and hypersensitivity pneumonitis. These are medical events, not inconveniences. Asthma is already the leading chronic disease among children in the United States, disproportionately affecting low-income households and communities of color. Adding a mold-generating appliance to an already asthma-burdened household is a genuine public health intervention in the wrong direction.

The complaint cites peer-reviewed research confirming that HVAC systems are common sources of indoor mold proliferation. Poorly designed or malfunctioning systems that fail to drain condensate can produce extensive mold colonization in ducts, walls, and household contents. These units were not installed in isolated chambers. They were installed in bedrooms, living rooms, and apartments where people sleep eight hours a night with the machine running and recirculating air across mold-covered coils. For the 17 people who reported symptoms through official channels, those symptoms included respiratory infections, not just sneezing. Respiratory infections require medical attention. Medical attention costs money. None of that cost appears anywhere in Midea’s recall.

The 1.7 million units sold represent 1.7 million households potentially exposed to elevated indoor mold risk over a five-year period. The CPSC received 152 official mold reports. Consumer complaint reporting rates for appliance defects are notoriously low; most people do not know there is a channel to report to, or they assume their symptoms are from something else. The 152 official reports almost certainly represent a fraction of actual exposure events.

Economic Inequality: The People Who Can Least Afford This Got Sold the Defect

Window air conditioners are the cooling technology of people who cannot afford central air. Renters. Apartment dwellers. People in older housing stock who have no ductwork. People in cities where summer heat is increasingly lethal and a $280 to $500 window unit is the difference between sleeping and not sleeping. These are not wealthy consumers with lawyers on retainer. These are people who bought a Frigidaire or a Keystone from Best Buy or Walmart and trusted the name on the box.

The financial gap this recall creates is not abstract. A household that paid $400 (a week and a half of groceries for a family of four) for a Midea unit now faces mold testing costs of up to $1,000 (one month’s rent for millions of American renters) just to assess whether their home is contaminated. If the test comes back positive, they face remediation costs starting at $1,500 (three months of minimum wage work at 20 hours a week) and potentially reaching $30,000 (more than a full year’s income for workers earning $15 an hour). Midea sold the product. Midea collected the revenue. Midea is asking consumers to absorb the downstream costs entirely.

The complaint puts the stakes plainly: “Defendant’s unlawful conduct as described in this Complaint allowed Defendant to knowingly realize substantial revenues from selling its Products at the expense of, and to the detriment or impoverishment of, Plaintiff and Class Members.” The structure of the harm is textbook: a corporation monetizes a defective product, externalizes the cleanup cost onto individual households, and then offers a partial refund calibrated to minimize payout rather than make people whole. The people who can least afford a $30,000 mold remediation bill are the people most likely to have bought a $300 window unit in the first place.

What Midea Collected. What It Left Behind.

What You Can Do Right Now

The brands affected span the entire big-box retail ecosystem. If you or someone you know bought a window air conditioner between March 2020 and May 2025 from any of the following brands, check the recall list immediately:

• Midea, Frigidaire, Insignia, Keystone, Mr. Cool, Perfect Aire, Comfort Aire, Sea Breeze, Danby, LBG Products (QB-8K CO)

The full model number list is published in the CPSC recall (No. 25-320) and linked at the bottom of this article.

• Check the CPSC Recall Database: Search Recall No. 25-320 at cpsc.gov to confirm whether your specific model number is included.
• Document everything: Photograph your unit, your symptoms, your receipts, and any visible mold. This documentation matters if you join the class action or file an individual complaint.
• File a complaint with the CPSC: Report your experience at SaferProducts.gov. Every report creates a public record that strengthens the case for broader accountability.
• File a complaint with the FTC: Midea’s conduct, specifically the concealment of a known defect from consumers, may constitute an unfair or deceptive trade practice under federal law.
• Contact your state Attorney General: Many state AGs have consumer protection divisions that track corporate misconduct patterns. New York’s GBL §§ 349 and 350 are already cited in this lawsuit.
• Follow the class action: The suit is Catalano v. Midea America Corp. and was filed June 9, 2025. ClassAction.org is tracking it. Anyone who purchased a recalled unit may be eligible for class membership.
