Tech support (Emily L) saved me a lot of grief on this one. *Great* tech support. This vent hood was easy to install. But it was making a high-pitch noise, and I was afraid that the bearings were gone on one of the motors or something like that. I called tech support, sent them a quick video of the noise, and they suggested I loosen the mounting screws half a turn. I was skeptical, but it worked like a charm! It is super quiet now and moves a *ton* of air. I could not be more pleased. It's really great to have that type of support.
I installed it 3 wks. ago and it's the best hood I ever had! I'll be short and sweet on the pro's and con's. I've read a lot of reviews on it and like other reviews there is good and bad. Some info on my install, 6" round ductwork to outside. Damper on outside vent also. Duct work is a short run and everything is secured real good. Some say the outside vent doesn't open that much. Then something is wrong with your ductwork or your ductwork run is too long? My outside vent is wide open on any speed.
Pro's: 6 speeds, I use #4 the most and I it is a beast! #5 & 6 is a jet engine going off! Speeds 1 through 4 are quite and you still can talk to people. Some said clock loses time, so far it's keeping correct time. This works great keeping smells from going into other rooms and again I only use #4 speed. I do a lot of cooking using oil with SS pans. This pulls all fumes from oil if I get pan too hot. No rattles or anything when on the higher speeds. Built solid!
Con's: 2 people needed for install, it's heavy for one person Back of unit says no closer than 31" above cooking surface, but description says different?
You won't regret buying this, study the install before you actually do it. I used a cabinet jack along with an other person to install
I bought this PS-18 a month ago to replace my old microwave with blower under cabinet due to poor suction. I am happy to make right choice buying this product. Good auction,Easy to install by DIY, and 6 speeds to control, worry free about filter clean issue.
