Is the crawl space big enough to actually crawl in without being a contortionist?

My sister has got radiant barrier insulation under her house (this triggers /diy/) and the first thing they do is to put down a moisture blocking tarp on the soil.

REEEEEEEEEEEEEEEEEEEEE

Hi thanks so much for your response.

Unfourtnately I do not have access to the crawl space but I imagine it is big enough since it runs the span of the apartments and the access is on one end.

So the first thing I tried was the extra oscillating fan in my living room.
I guess I could try leaving my blinds open so the sunlight drys things out a bit?

Also I don't have a floor drain otherwise I would just set up a dehumidifier

You need to talk the manager/owner into checking out that crawl space. It could be damp.It could even have puddles of water down there due to drainage problems.

Easy to fix now. Very expensive if mold starts to grow or the building rots.

I couldn't imagine AC not being able to dehumidify an apartment so small. Are you sure your AC is functioning properly?

>Everyday I leave my ac on 70 and my ceiling fan and even have an additional fan in my living room and it is still usually around 70% humidity
I'd say your AC has a blocked drain or is otherwise fucked. Unless your floor is completely swamped there is no way you have 70% humidity with proper AC on. Turn it off and see how it gets. Either way the crawlspace needs to be looked into too, cause this isn't normal.

Buy a dehumidifier.

A dehumidifier is an air conditioner without an external condensate drain an no exhaust for the heat gain.
He has an air conditioner.

There's this thing called a "de" humidifier which "removes" the "humidity" from the air. Look into that.

Currently using a dehumidifier but I don't have a floor drain and it fills up fast that's why I'm trying to fix the real problem

This is what I was thinking, although usually when the condisate drain is plugged it leaks water inside and I can't find any water. I'm going to google the ac unit and find out where the drain is and make sure it's draining properly because I think you're right, clearly the ac isn't removing the humidity.

I appreciate the responses I got some ideas and will delete the thread

Sorry Op, I dont know if you will solve this here. Most browsers here dont own a home, which equates to not actually doing anything themselves. Essentially you've come to the wrong place to ask a question like this.

>>1239823
Has pics and information, which is more than most here can say. I'd go with this. I'd help you but I have a full basement, and do not have humidity problems, so my experiences wont help you. Good luck.

This.
I tried fans and shit in my basement but ended up getting a dehumidifier.
Went from 85% humidity to 35% on continuious. About ~$100/mo for a 70 pint on all day and night though...

Put it on the kitchen counter and drain into the sink. I know it sounds jankey, but it's an apartment and there is only so much you can do.

Assuming outside humidity is low (I'm UK, so we have that) - then pretty much any damp problem inside a house will be solved by improving ventilation. I have a damp lifestyle (lots of big hairy dogs coming into my house several times a day in the winter leads to a lot of damp) so I installed a MVHR system - works brilliantly and costs almost nothing to run.

If outside is humid though, a dehumidifier and $$ is your only solution.

hey there, I work in HVAC. Listen to the people telling you about the vapor barrier underneath the floor. If the house is well insulated for heat and moisture, then your normal A/C should be able to dehumidify the space.

if the A/C is oversized for the space it wont dehumidify very well. Is the A/C running for a decent amount of time? an oversized A/C will still cool the space, but it doesn't run long enough to dehumidify.

the only thing i can think of is to make sure the A/C is draining water correctly and making sure your return air ducts are connected.

temp fix to help prevent mold, get dehumidifier(energy efficient one), get nice tube for bucket, have it under your sink up on a bucket or install a rack for it above the drain. Tap into the drain on the side and put hose in it, make sure to have one way high pressure valve for when you actually use the sink. No see the dehumidifier, drains into sink.

Get a stick and tape it to a phone/camera and take pictures of your basement AND attic OP.

Also of front/back of AC.
