12,000 BTU Window-Mounted Room Air Conditioner

Arrived heavily damaged

Hi, Geo! This model does not require an exterior mount and can be installed using only the included brackets and lower window pane. We typically only recommend a support tray for heavy-duty models 20,000 BTU and up. ~Ashton

I don't see why not. It will just be a real challenge to create the wall opening and size it to fit the unit.

is it a 110?

No.Read the specs. The unit requires an opening of about 15 inches or slightly less for a snug fit but no way will it fit an opening of only 13 inches. I doubt even their smallest unit would fit an opening that size.

No.Like all modern window units, it uses the condensate picked up by the outer fan to aid in cooling. If you drain that condensate, you get less efficient cooling. The condensate is not a problem. Problems come when rain water is added to the condensate as the unit has no overflow so the outer fan hits the standing rain water causing it to bog down and the fan motor to wear out prematurely. it's a design flaw but it's intended not to have nor to need a drain.

I'm not sure what you want to know. How cold can the unit get a room? That would depend on the btu's of the unit and the size and other factors of the room. Or how close to the set temp does the unit try to maintain? I'd say it takes about a 2 to 3 degree rise in temp for the unit to kick on and it usually kicks off within 1 or 2 degrees of the set temp. Of course it's different depending on whether you're using the remote sensor or the unit thermostat. The remote sensor seems more accurate at sustaining the set temp while the room temp can vary more before the unit thermostat reacts because I suppose the unit is reacting to the temp right in front of the unit rather than the temp of the whole room.

My last unit arrived with a defective thermostat so it did only work with the remote sensor, but it's designed to work either way. I love the remote sensor. It keeps the place I'm sitting at the set temp. But it's really picky to operate that way. The remote has to be in direct line and a short distance from the window unit and it has to be left exposed to the air and dust and whatever can soil it. Plus when and if there's a hiccup in the power the remote sensor is cancelled and must be reengaged.

Yes, it comes with the flexible side panels and foam strips for around the edges. But it was changed a bit from the older model I replaced with it. The older model had thick cut-to-fit stiff foam reinforcement panels to insert into grooves in the flexible panels to hold them extended for a snug fit. It still comes with the cut-to-fit panel inserts but they removed the inner grooves for them and made them from much thinner foam, so they don't really insure a snug fit of the flexible panels anymore.
