Quiet with great airflow spread out across the entire width.
Installed the unit about a month ago. It's been working great ever since. The current draw is less than the 10,000 BTU unit that was previously installed. Very quiet operation. I only use the air conditioner function since the equipment in the building generates heat.
I installed this last year for a 950 sq foot area and it has worked very well. It was a replacement for an older split unit so the extended copper lines were already there. All I needed to do was hang the unit, flare the new fittings pull a vacuum and charge up. Easy install, great price.
