I don't really want to shill out an additional 200 a month for elecricity.

Already did the two-hose diy conversion, but is there anything else I can do?

You could become an engineer, electrical, mechanical, or chemical, then build a more efficient one.

Just make sure its clean, have other fans in the room to help cool down the space better, and run an extension cord to your neighbor's outlet and have them pay for it.

put good insulation on the hoses, and make them as short as possible.

Short hoses, a good window seal that's insulated, that's about it. Ideally you'd want the compressor outside because it's a heat generator, but you can't do that with this kind of design, unless you make a big hole in your floor and have the bottom half of the unit sitting in your basement. It's possible the internal sealing isn't very good so you could open it up and add more foam to better separate the hot and cold sides, but I doubt it'll make much difference.

Found out the hard way that when my windows are open there's a huge air gap that opens up between the two windows, bugs and warm air were coming in so I had to add some insulation foam there.
>>
Next time, if you want to ghetto mod something cheap, mod a window unit.

A window unit can be two hose modded too, but you can't really do the condensation trick on a mobile (window units spray condensation on the condenser).

There are probably slower more energy efficient methods. My understanding is that it's an air conditioner retooled to just drip. HVAC has heat pumps that operate on a temperature gradient and utilize ambient heat energy, vs AC just compresses and pushes.

A better solution is probably isolating the space from water intrusion.

this, and also dont use an extension cord.
remove any filters the unit has
how was your DYI conversion? post pics so we can rate it.
is your electricity cheaper at night? if so, run it at full blast during the night and turn it down during the day.

Insulate and air seal the space you're trying to cool.
