I love my Windmill window ac the beautiful style & design, compact size not bulky like the others. The ease of install, was a breeze and smooth quiet operation and installation myself was the best! I had a small damage with the packaging of box once delivered. Which possibly could have caused my unit to have an issue with the operation. I reached out an spoke to customer service (Eli ) who was very knowledgeable in determining my issue..Very kind concerned & very compassionate. He immediately put in order for replacement of my defective unit.. Glad to say i was back up an running perfectly..Kudos to Eli & thanks again for the Best Customer Service Ever‼ My new unit is working fine..I'm so happy i choose Windmill Ac as my (1st choice and only choice) for window ac's in the future & definitely recommend this unit all my friends & family.
