Unfortunately the item arrived and the Shipping Box showed considerable repair taping on bottom and cracks on cardboard box.
It clearly was dropped from a considerable height. 
After unpacking the bottom of Air Condition unit was badly damaged.
Unit fan was noisy and clearly beyond repair. Wayfair replaced unit after following their protocol for damaged goods received.
I certainly will buy from Wayfair again, after such great response from the company regarding my damaged order received.
Thank you for dealing with my problem so quickly.
A happy customer.
