I usually don't write any reviews but... all i am reading is negative reviews. Ordered 5 units in the past 2 years. NEVER had any problems, all items shipped in a timely manner and in perfect working order.
If you are not an HVAC professional, then you should not be installing any mini splits. Sometimes you have to add freon to the units if the line set run is further then 50 feet. ALL units still currently working just like new.
