    Hey all.

    SoCal resident here in need of some better A/C power in my one bedroom apartment. I do not have central air so my room gets hot during the afternoon. I am in the market for a good evaporative cooler, could anyone be of help to recommend me a good unit? I don't know how much I should spend but I'm hoping it's no more than $100. Thanks for your input!

    As an HVAC engineer, I need to advise you that this is a bad idea. Just get a window A/C unit.

    A Window AC big enough for one room runs 90-120 dollars and will be a much better option.

    Evap coolers are only effective in very hot areas like desserts, in a place like So Cal, you just peed away 100 bucks. They add humidity, not get rid of it.

    Buy a Window AC. You'll be very happy with a basic unit.

    While I totally agree with the AC recommendation: I wouldn't call SoCal a humid place. It's a huge area and - at least by area - much of it is arid and hot.

    Yes, there are nice microclimates near the coast and that's what a lot of people think of when they think SoCal, but the truth is flatter, drier and hotter than that.

    Hmmm, I guess I didn't realize SoCal was particularly humid. Granted I've only been down there once, but I got the impression it was on the dried side.

    Evaporative cooling is most effective when there's enough available headroom on the enthalpy curve to lower the dry bulb air temperature without bringing the relative humidity above about 60%. Looking at a psychrometric chart and ASHRAE weather data, there are very few climates that could safely (see below) benefit from one of these. Generally, they work best in places where the relative humidity is somewhat low (20-30%) and the dry bulb temperature is in the low 90's F or less.

    Installing an evaporative cooler, regardless of climate, generally requires at least a semi-permanent water connection and drain. They can get pretty messy and be a bit of a chore to clean and maintain.

    The more pressing issue is that these have been shown to promote the growth of black mold due to the lower temp and humidity in the environment they serve. That's a health hazard.

    Thanks for the explanation. I've used them quite a lot, but that's when I was in an extremely hot (100+ F) and dry environment. I didn't realize their useful operation was so narrowly constrained. Cheers!

    Referring to all of SoCal, as varied as it is, as humid is a bit naive.

    We had one in Palm Springs that worked great (a/c too).

    Have friends in San Bernadino that have one even now, and use it (again, with a/c as well).

    I don't know of any a/c units for $100.

    As you said, the climate here is quite varied.

    I have friends with a window AC that they got from Target for around $115. It's good enough for one room, it's not going to do a whole apartment.......but maybe that's all that's needed

    For one room its perfect, and will perform much better than a Evap cooler for one room.

    I've seen them as low as 85 dollars in even mom and pop stores on clearance.
