Hisense 550sq.ft Dual Hose Portable AC

OK - so I read other reviews and came into this purchase already critical of the product. But I wanted to give it a try since there arent many Dual Hose Portable air conditioners out there. This is what I wanted because I wanted to use it in my camper and the dual hose makes it much more efficient to cool down something that isnt very air tight (look this up if you dont know the benefit of dual hose). Thinking this thing would not work, or immediately throw error codes, I decided to try it out in my ~1200 sq ft living room before throwing out the packaging or brigning it on a camping trip. And it did the job, it wasn't as good as central AC but it kept the room comfortable in July/August heat (~90F). It worked so well it never made it into my travel trailer, and spent the entire summer cooling my living room. Now - fall and winter have arrive and I know a heat pump uses less energy than burning my furnace, so why not give it a go. THIS THING HEATS! I cant believe how well it heats my first floor, now when its 15F outside you have to lower your expectations, but in the mid 30s and 40s it heats the whole room. I am sold that this is now a part of my living room. Some little things to consider: When in AC mode it drips the condensate on the lower heat exchanger, so it evaporates and is blown outside (another dual hose benefit) so I never had to drain it. But in heat mode the exchangers are in reverse, so the condensate drips into the pan and it throws E5 errors after about 30-60 minutes. Just drain the pan with the lower drain plug (but that becomes a pain), so position this somewhere you can run a drain hose. The drain can be finicky so sometimes it needs a little help getting the water moving out the hose - I put a small piece of wood under the front wheels to tilt it back to help with this and it will run all day. Summary: Dont expect this to cool/heat your large home - but it does a fine job either in smaller spaces or supplimenting something else (in my case a wood stove in the winter, or a window AC somewhere in the opposite side of the house). Dual Hose is the biggest upside to this unit, it is insanely more efficient than a single hose unit. Take the risk - I cant speak for all of them - but at this price its a very affordable entry into a combo AC/Heat Pump unit.
