Frigidaire knows its way around an icebox, having developed the first self-contained "Frigerator" in 1916, and is even thought to be the origination of the term "fridge." Part of the Electrolux family, the brand continues to produce high quality appliances, including built-in, window-mounted, and portable air conditioners that keep us cool on hot days. If, on days like this, you find yourself spending time in front of your fridge with the door open, it may be time to replace a part or two in your A/C. We have the quality Frigidaire air conditioner parts selection and experience to help you with any problem, whether the temperature is not getting low enough, the fan is not working, your coils are frozen, or the unit is noisier than usual.
