Nothing special here, either. Just replaced the window AC in my reloading shack, the previous one lost its refrigerant after less than 2 years. Most manufacturer's warranties are only one year. Normally I don't get extended warranties, but with the luck I've had with window ACs over the years, I'm glad I got it on the last one. The new one (Frigidaire) has 5 years on the "pressure system" so we will see how long it lasts.
