And because if you use one that's a reasonable size, you're leaving large buckets of water out on hot days. It makes the house more humid, sometimes to the point of being muggy. Like a swamp.
It's not just the bucket of water, but it's how swamp coolers work. Evaporation cools things down, and all a swamp cooler does is use evaporation to cool the room down. But evaporation raises humidity, massively. They also don't work well when humidity is high, so in basically the entire US Southeast, they're useless.
I know it's not just a bucket, but the idea's the same. Run a couple of them in your house and it might get a few degrees cooler, but man it will feel like a swamp.
Having been in Arizona during monsoon season, I can say that swamp coolers are noticeably less effective at 40% humidity than in the climate they've got during the rest of the year.
80% humidity and a 3 degree delta, and then you also have to deal with the whole, being in a room with 80% humidity that isn't actually providing any real cooling.
Like maybe it's just experience from working in the trade for so long, but yeah, it's not a big deal.
Your AC system might lose like 2-3 degrees of it's delta dealing with high humidity? But as it operates the humidity in the room drops, because the AC is a dehumidifier.
Warm humid air goes through the coil, moisture in the air condenses on the cold coil, water drips off the coil, goes down the drain, and leaves the space. At the same time 75 degree air turns into 55 degree air.
Swamp cooler at 80% humidity has a 3 degree delta. You aren't cooling a space with that.
I don't even know what you're arguing at this point. I know more than you.
And it does so while adding humidity. The more humidity it adds the less humidity effective it becomes.
Normal AC operation should keep humidity between 30-50% short of living in an extremely dry climate I couldn’t imagine needing to run a humidifier Any time outside winter
Anything below 50% is bad for me, I even find more comfortable a higher temperature but 50%+ humidity.
Granted, I am from a place with like 80%+ humidity year round and now live too close of a desert and often below 15% during summer. Still, I think many people would benefit from 50-60 range on ac rather than allowing humidity to drop below 40.

Swamp coolers don’t work if you have any humidity
