 AM 1420 WYMS. What's worse than your air conditioner giving up in the heat of the summer, forcing you to buy a whole new system? Having to do it again a few years down the road. That's why you choose the Amana brand. Nearly every Amana brand central air conditioner comes with a lifetime unit replacement limited warranty. If the compressor breaks to the original registered homeowner, we'll replace the entire unit for as long as you own the home.
