36000 BTU Quad Zone Mini Split Air Conditioner - Heat Pump - SENA/36HF/Q

I recently purchased one of these systems. I was able to do the mechanical installation myself and then had the licensed tech come in, check my work, test and charge and do operational checks. We are super happy to have control of individual zones and the speed we can get a room to our desired temp compared with our old central air system. Can't wait to try out it's heating ability this winter. My only complaint is the small size of power input terminal strip. It should be lugs capable on #8 wire.

I use to burn wood but now I just got two heat pumps. One on each floor but usually only one unit on down stairs heating the house and I got the furnace took out and no more mess from fire wood. No trouble with either unit. One unit is close on 4 years old and it’s looks the same as the Day I bought it and it puts of great heat. Best thing ever.

Electricity use is lower than with the window units that this replaced and it is cooler and much quieter. We can finally sleep without earplugs! We will have to wait for winter to check heating performance. The outdoor unit has a design flaw that I hope does not cause trouble later. The terminal block used to connect the electric supply is undersized for the current rating of the unit. It uses the same size connections as the low current lines that control the indoor units. The room temperature from the indoor units seems to vary quite a lot from their setting especially in the smallest room. (Both getting too cold and then too hot). Setting the unit to "silent" mode helps a bit because it slows the fan to the minimum so that the room doesn't cool as quickly and temperature is more consistent. I did this install in a high rise condo apartment which complicated the project beyond a normal installation. Because 2 of the indoor units could not be mounted where they could drain outdoors, I had to install a condensate pump and also drain plumbing to support it along with the other unit that was placed on an interior wall. I also recommend using a product like Nylog Blue when connecting the flare connections on the linesets to avoid any leaks and have a pressure test done with nitrogen.
