I contacted Windmill Air to see if I could order new parts to move my Windmill A/C to another window with a different dimension. Ms. Maggie greeted me from customer service, and she was able to order the parts I needed to move my A/C unit to the new location. I paid for shipping, but it was only $6.
I have been happy with my unit and the customer service I have received from Windmill. I'll be glad to continue supporting the company and hope they provide more innovations for future product development.
