As the weather begins to heat up ahead of summer, you may want to take a closer look at your air conditioning units.

The Consumer Product Safety Commission says nearly two million window air conditioners manufactured by Midea are being recalled.

The CPSC says that Midea U and U+ window units are being recalled due to a drainage issue, which can lead to mold growth.

The commission reports at least 152 instances of mold found in air conditioners, with 17 cases where individuals reported symptoms like respiratory infections, allergic reactions, coughing, sneezing, and sore throats due to mold exposure.

These air conditioners were sold under various brands such as Midea, Comfort Aire, Danby, Frigidaire, Insignia, Keystone, LBG Products, Mr. Cool, Perfect Aire, and Sea Breeze.

They were sold at stores including, Costco, Home Depot, Lowes, Walmart, Best Buy, Menards and BJs.

The model number can be found on a label on the front right side of the unit when facing the air conditioner.

The CPSC says that people with recalled air conditioners should immediately contact Midea for free repairs or a refund.

You can find more details on the recalled products at the CPSC website.
