I purchased a NanoMaxA12000EH several years ago to cool a large bedroom of around 300 sqft. The equipment is advertised for up to 400 sqft. Presumably more than adquate for this application. Window units are sized at about 20 btu per sqft or in this case 6,000 btu. To be immediately noted is that it takes a lot more btu per square foot for this and other portable air conditioners to achieve the same outcome as a window unit half the size in btu.

So how did it work? Not well at all. On a hot day starting with the room in the mid 80 degree range with say 60 percent humidity it cannot cool the room down. It may drop the temperature 1 degree per hour. If we cool the room with a fan it can drop the temperature from say 78 degrees to 74 degrees in 2-3 hours. It of course provides comforting cool air if you focus on you.

A call to AMCOR support revealed that the technician thought I was definitely at or above the limit of its capacity at 300 sqft.

Purchased my Amcor ALTL 12,000EH about three years ago. Wanted one to cool and heat my windowless two car attached garage. I decided to set it up on a work bench and vent to the attic area rather that cutting a hole in a wall or door.

Living in coastal Georgia it does get the temperature to comfortable level in both summer and winter.

This is the most terrible piece of electronic/small appliance/ home equipment I have ever had to deal with. The unit is ridiculously heavy, and therefore difficult to move and very frustrating and difficult to position near windows of various heights from the floor. It heats the room as much as it cools, rendering it as "useful" as a fan sucking in air in a window on a hot and humid day. It does this because the pipe that "vents" to the outside radiates heat through itself. The hot part of the A/C unit is still in the room with you, not hanging out the window, and therefore renders the cooling ineffective.

Go to insulate this trash thin plastic pipe, and its fitting cuff teeth that fasten it to the back of the unit snap off. It is poorly built, over-priced, and a frustrating waste of money and time.

The graphical display on the unit takes a thorough re-read of the manual to interpret all its obnoxious symbols for operation. I cannot wait to bring this back... Read more
