Senville 9,000 BTU Ducted Mini Split AC/Heating System, Concealed Duct, Built-in Water Pump, Wall Thermostat, 16 Ft. Installation Kit

After owning 3 of these units for several months now, I can definitely tell you to stay away! They were fairly easy to install (if you have the right tools). They worked well in the summer up to about 80 degrees. Over that they struggled. After a couple months, one started making a very loud noise. I called support and they told me to restart it and they would call me back in 30 minutes. I am still waiting for the call, 52 days later, and it’s still making the noise. The thermostat has a 3 degree +/- which means you set it for 70 and the room swings between 67 and 73 all day and night. I asked support and they said that is “normal”! They were working ok in the cold until it got down to 0 and they completely went to crap. Blowing out cold air and leaving my family to freeze. Luckily I have a fireplace and was able to save my family and my plumbing! Save your money! These are junk and their tech support is a joke!!!!!!!!!

This unit works great. I finished out a 16’x40’ barn for my wife’s new doggy daycare business. I fabricated the supply & return plenums and ran two runs of ductwork with three vents. This unit may have been a little undersized for the dimensions of the barn. However, as well insulated as the building is, it kept it cozy & warm in the winter and has done well this summer. My only two complaints are that there should be basic plenums available for purchase and the thermostat could stand to either be of better quality, or replaceable with another model.

My biggest problems with this are: absurdly loud beeps with each button press, lack of fan control during heating, and lack of available duct connectors. A starting plenum would be really helpful. You can make your own, but 99 of 100 people are not going to. That's too bad because otherwise the 9k unit will heat and cool 2-3 bedroom/bathrooms just fine.

Manufacturer needs to list dimensions on the Amazon advertisement

Ok so I bought this little unit to do my new laundry room and my 1 room garage/workshop. Man I ended up being able to do both those rooms, an adjoining 1/2 bathroom and dump two vents into my family room. This thing is a champ. My power bill dropped by 20% by adding this thing since it allowed the big unit to not have run all the time trying to do rooms that were added later. Its super quiet so you can't even hear it running. Oh and Senville, what can I say best customer service I have dealt with. I accidentally threw out a part I needed for install and they shipped me one for free. Even though I admitted to throwing it out.
