My sister purchased a Mitsubishi Mini-split air conditioning unit for me, and the Air Handler is defective. AC Wholesalers will not honor the warranty because it was installed at a different address than who purchased it. It was installed by a professional, and ACW knew the circumstances at the time it was ordered. Nothing was ever said about this voiding the warranty. In fact, I was initially told that it would be covered. Now they are saying that I was misinformed. I do not recommend this company.
