Biggest pain with these units is no one installs them due to sizing so you either need to do it yourself or hire electrician because you will need to know how to wire. This is not the appliances fault in anyway- just be prepared for this issue with any double wall unit. Best part about GE is their commitment to size. Our previous unit was a GE and was over 25 years old. We couldn’t get any other brands due to size without making changes to the wall, trim, etc but GE commits to uniform size so it was easy to buy from them.
