The Internet’s Favorite Air Conditioner Has Been Recalled
Summer is objectively the worst time of year to go without air conditioning, even if it’s just for a few days, but alas, approximately 1.7 million consumers may have to do just that.
Midea is recalling its popular U and U+ window units due to drainage issues (specifically water pooling) that can lead to mold growth, increasing the risk of respiratory illness and other mold exposure symptoms. The U series is beloved by consumers and reviewers for its energy efficiency, smart features, and unique design that allows the window to open and close around the unit.
The affected units were sold by Midea, as well as other brands. If you have a window air conditioner, here’s what you need to know.
Which Midea devices are subject to recall?
According to a notice from the Consumer Product Safety Commission (CPSC) , the recalled U and U+ window air conditioners were manufactured by Midea and sold under the brand names Midea, Comfort Aire, Danby, Frigidaire, Insignia, Keystone, LBG Products, Mr. Cool, Perfect Aire, and Sea Breeze. The consumer alert lists specific model numbers, which along with brand names, can be found on the units (look for a label on the front right side). They came in three sizes — 8,000 BTU, 10,000 BTU, and 12,000 BTU — and measured about 22 inches wide by 14 inches high.
The devices in question were available between March 2020 and May 2025 and could be purchased at Costco, Menards, Home Depot, and Best Buy, among other retailers, as well as through Midea.com, Amazon.com, Costco.com, Menards.com, HomeDepot.com, Lowes.com, Walmart.com, BJs.com, and BestBuy.com. Retail prices ranged from $280 to $500.
Midea sold about 1.7 million recalled air conditioners in the United States and another 45,900 in Canada.
What to do if your Midea air conditioner has been recalled?
Midea offers consumers the opportunity to request a repair or a prorated refund. To get started, go to the Midea recall site , select your model number, and enter the 22-digit serial number found on your device. You don’t need a receipt or proof of purchase to participate.
You can also contact Midea by calling 888-345-0256 from 8:00 AM to 5:00 PM Eastern Time, Monday through Friday, or by emailing midea4028[at]midea[dot]com.
If you request a refund, you will need to either ship the recalled unit back to Midea using the shipping label provided or provide a photo showing that you have cut (disconnected) the power cord. Refunds will be prorated based on the date of purchase and will take 3-4 weeks to process.
If you choose repair, Midea will arrange for a technician to come out to install a new drain plug or send you a repair kit (depending on your model). DIY kits will be delivered within two to three weeks, and Midea will contact you within five days to schedule an in-home repair.
In the meantime, you should follow Midea’s recommendations to check for mold before continuing to use your air conditioner. Midea has received 152 reports of mold, with 17 consumers reporting effects ranging from respiratory infections and allergic reactions to sneezing and sore throats.
