Is there a dehumidifier out there that won't heat up the house?

I haven’t tried it myself, but I’ve read that rock salt placed in a bucket with holes drilled in the bottom, and placed in another bucket, to catch the water, works. Here is a link to several DIY ways to dehumidify a room.

not really; dehumidifiers work in a similar principle as air conditioners; the condenser puts off heat as a result of normal operation

you'd be better off running an AC unit as they cool air and dehumidify

whereas a air conditioner intakes heat & moisture from your house and exhausts it outside; a humidifier intakes moisture and exhausts water and heat into the same room

You could try setting the dehumidifier relatively high so it drops the humidity but only slightly. I've got one sitting in a motor home and I've noticed that if I turn it way down so it runs almost constantly it will be hot in there, but if I'm only trying to drop the humidity a few percent it feels cooler in there than it does outside.

Many many years ago I knew a family down in Florida, not too far from the beaches but somewhat off the beaten path. They had a gift shop/clothing store in their yard that they only opened when they had customers so they didn't bother running the air conditioner. It always felt cool in the building and I remember them saying it was because they had a dehumidifier. I've wondered why it didn't heat up in there. Dehumidifiers are going to give off heat, there's no way around that.

Be calm everyone I'm a carpenter.
Yes ma'am I know a little about A/C. You say it's on 64 but it's still 80°
First thing to do is look at the inside part of the unit and check for ice. The chopper leading into the machine will sometimes freeze up. Second check the filter. If it's dirty air won't pass through, and if it was me if take it out for the night. Third of all an AC is basically only guaranteed to make the inside 26°cooler than the tempt but most do a little better. Fourth is your fan in the on position or the auto position.
If you check those I'll wait here for your answer. First fifteen minutes are free. So is the second and third I was just rushing you. Quit reading

I'm at a loss. I thought air conditioning, which you seem to have, also dehumidified the air -- that's why it drips. Not sure why you would need a dehumidifier if the air conditioning is working correctly. :(

Get a portable A/c with dehumidifier. Mine doesnt get hot at all and it works so good. You gotta hook the exhaust up to the window.

What’s the outside air temperature?

All dehumidifiers do is take the moisture out of the air.

Is your dehumidifier collecting water? Is the screen clean?
