@sarina: I have had the Kobe RA02 for about 8 months now. Being an engineer, I did the install myself, although the chimney cover is still not in place, as I need to redo the crown molding behind it (procrastination is the name of this game). Overall I like it, but that doesn't say much, as my previous ventilation was just a fan-in-a-ceiling-hole. The quiet setting is quiet, but the other two are noisy; without previous experience, the "sones" numbers don't translate well into actual noise levels. Otherwise, on High, the hood is pulling out all the smoke and airborne grease steaks in a cast-iron skillet produce. You will have to open a window or install a MUA to help it pull all that air volume. The baffles need scrubbing every month or so, but that's a very small price to pay for not having cabinetry and walls smeared in grease. The model you're looking at is a little more elaborate, as it has some sort of electronic control. The RA02 is bare-bones, just two rotary switches.

They are set up as recirculating vents, and they do just shoot the air back out the grill at the top front of the hood, or sometimes out a grill in the soffit. The grease filters trap the same grease as if they were vented out, and they have charcoal filters although I have never known anyone to change the filters. So they are removing some of the grease and blowing the hot air back into the room. In some locations this is all that is allowed.

houses14, my Imperial range hood is not an insert, rather an under cabinet ss hood. However, the materials used, and the quality of construction, the fan motors, are the same with minor variances to allow for space restrictions within the smaller size of my hood. Construction wise, it is all that I had hoped for, was easy to install, and has functioned beautifully. Packaging and shipping were excellent. The ss is marine grade. This means that the amount of chromium in the ss will prevent rust from forming in the interior of the hood over time. The electrician informed me that their fan motors and switches appeared to be top quality. The warranty for my hood is 7 years, which is almost unheard of in the industry. Their specifications and installation instructions are right on to allow for optimal operation. For example, my duct is 8" from hood to roof jack and had to have a certain rise in height from the hood before the first angle in the duct work. Baffles remove and reinstall easily for cleaning. It was a joy to call Imperial direct with technical questions at their manufacturing headquarters in California. Someone was always immediately available to answer my questions regarding their vent hoods or recommended installation. My installer was promptly referred to their engineer for technical assistance as I requested that the wiring that would automatically turn on my hood once a certain temperature below the hood was reached be disconnected as I did not want that feature. To me, having that level of service available when answers are needed means a great deal. I found that the folks at headquarters were always honest even if it wasn't the answer I wanted and that they knew their stuff. Their light and fan switches are continuously variable which is rare on vent hoods. This means that they both function like a rheostat with a continuous increase, or decrease, rather than clicking up or down discreet notches, such as level 1 to 4. Also, I liked having the option of installing the switches wherever I wanted remotely, rather than being mounted to the underside of the hood. The hood easily handles removal of odors, steam or grease beneath it's surface. I've found that if the hood is allowed to run for about 10 minutes prior to cooking that it can be operated at a lower level and do a good job. The hood on low is fairly quiet but is noisier than I had anticipated at higher levels with having dual fans and baffles. Also, highest cfm level is 1000 which is a factor. However, I used a different size led bulb than Imperial recommended. I now have a gap around the bulb that needs to be filled with a rubber gasket. Also, the temporary roof jack is too large, and the correct one is waiting to be installed so the jury is still out on the noise issue. Noise level was quite an issue for me, but even if it remains unchanged, I would still buy the same hood given how pleased I am with the overall operation and that I can easily live with the noise that I now have. I'll have to look up the name of the online vendor I used and will add that information tonight.

Hello Houzz Community! I found this thread when Googling a similar topic. I'd like to replace my under cabinet hood with a wall mounted hood, and yes I know I have to remove the cabinet above the current hood which I'm fine with (see photo). My existing under cabinet hood vents out the wall to the side of my house - see photo, and note the vent is not blocked by those shrubs, there is space around it, you just can't tell from the angle of the photo :-) So my question is....can a wall mounted hood be installed to vent out the existing vent in the wall, or does a vent need to be created in the ceiling? Also, what type of professional can help answer any related questions I have about this? Would I ask the wall mounted vent manufacturer? Or a handyman? Thank you in advance for any guidance! I am a newbie homeowner and am learning as I go, so truly appreciate you taking the time to share your knowledge with me!
