(NewsNation) — Approximately 1.7 million window air conditioners are being recalled across the U.S. due to 17 customer complaints of illness attributed to mold growth inside these devices.

The Midea U and U+ window air conditioning systems might not drain properly, leading to mold development that “can present risks of respiratory problems or other infections for certain users,” as stated by the U.S. Consumer Product Safety Commission.

Nearly 46,000 units were also sold in Canada.

A total of 152 instances of mold presence have been reported in these white AC units, with 17 individuals claiming that exposure led to symptoms such as coughing, sneezing, or other allergy-like reactions.

Units were sold under the brand names:

• Midea
• Comfort Aire
• Danby
• Frigidaire
• Insignia
• Keystone
• LBG Products
• Mr. Cool
• Perfect Aire
• Sea Breeze

The Midea air conditioners fit in windows and resonated with consumers because of their unique design, which allows consumers to close their windows “through” the unit.

The units were sold from March 2020 through May 2025 for $280 to $500 in-store and online at Costco, Menards, Best Buy, Home Depot and more.

Customers who purchased the units can get a free repair or potentially a prorated refund by contacting Midea.

Consumers who choose to use their air conditioners while awaiting a repair can go to www.MideaUrecall.expertinquiry.com to find out how to inspect their unit before continuing to use it.
