Should a dehumidifier have to be emptied every night?

I live in Houston where it is obviously humid. Back in September, I had an issue with my air conditioning ducts sweating in the attic because I was keeping my thermostat (at night only) set to 65. Caused a stain on one part of the ceiling on my second floor.
In an effort to try to be able to tolerate a higher room temperature, I bought a good sized dehumidifier for my bedroom that runs at night. It doesn’t even make it the whole night without completely filling up. I feel like even in a place as humid as Houston, that is excessive.
Should I be looking for other problems with the house? It’s about a year and a half old but I bought it within the last year and has a year long builder warranty.

Actually in the summer it was only like $150.
The house is a “green” energy efficient one that also has three different zones. I only keep my bedroom at 65, not the rest of the house

You shouldn’t be having that issue.

You could have a heavy duty dehumidifier. Do you find you never have to pee anymore?

He lives in Houston with energy deregulation. You have your choice of 64 providers and 314 different plans. Competition brings down the price. My electric bill for July in Houston was $158 for a 3,887 sq ft home.
I apologize if my comment about cheap electric in Houston offends anyone.

What is it rated at and how big is the reservoir? I have a 70L/day dehumidifier that runs in my basement but the reservoir is small, only 16L. So if there is enough moisture in the air it will need to be emptied 4x/day. I have it set to run to a sump though so it's not a problem for me.
But yeah it's not uncommon at all for your situation to occur. Just means your upstairs is humid or you have your dehumidifier set to run till it detects a very low humidity level.

Mine in July was approaching $300 for a 1200sqft home. Thanks Entergy

Mine is in my garage. Has to be emptied literally every morning

They will def fill up. That's why a lot of people add a hose to run outside or into sink or tub.

Stupid move. Your dehumidifier is putting out heat and not energy efficient

No, what offends me is that in this context "electric" is an adjective. "Electricity" on its own or "power" modified by "electric" would be the correct goddamned noun to use.
"Electric" used as a noun is only proper when referring to a particular device that is electric in nature.
For example:
Alice: "Bob, which chair should we give Mudminnow for murdering the English language?"
Bob: "The electric."

they all have a built in drain line so connect that and run it into 5 gallon bucket to make it last all night.
as for the humidity it takes forever to suck out all that moisture in the walls furniture and fabrics so its not uncommon at all.
your a/c unit easily makes over a gallon of water every hour so your situation isnt unusual. most of those dehumidifiers dont have big drain pans anyway.

I would bring it up to the builders this is signs of a poorly built home. That’s means you are getting way to much outdoor air into your house. You should not have that much condensate forming.

This is often caused by the air conditioning system not being sized correctly for the house. Builders will just use some "rule of thumb" for determining tonnage and not consider many of the other factors involved, or they have the idea that using bigger units than needed will save on power usage. In Both cases the result is a system that does not run enough to remove humidity from the house. I bought a high energy efficient house with this problem, I could easily cool the house, my power bills were very low, but the house was always humid. After two summers had the system replaced with the proper size and everything is great, house is cool, bills are about the same, and no longer need a dehumidifier.

I’m no expert here, but I’ve always thought that dehumidifiers in most homes in the gulf region are practically useless. Homes breathe a fair amount if not built specifically to counter it - something about an ACH-50 test showing most homes naturally exchange the air quite often throughout the day (maybe a contractor could correct me here?). And down here, if you’re home is constantly exchanging air with the near-pressure-cooker humidity we have, then I think you’re only bailing out the water as fast as it comes in.
I do know after lightning hit my mom’s home and busted a pipe in the slab, which flooded everything near it, they brought in several of those large (washing machine sized) dehumidifiers. They ran full blast, were loud as hell, and they pulled so much water out of the air that they had hoses running to the nearest sink... those hoses looked like they were attached to a water spigot with it about a quarter open.

Of course.
I lived in Houston and more recently in NOLA. ALL dehumidifiers (even the one on our sailboat) were set up to drain into sinks.
Or do you find moldy leather shoes more comfortable?

Have you measured the humidity in the room? Design conditions should be between 59-60%. Higher and you will feel miserable/muggy. Lower will dry out your sinuses and cause static issues.
If your ducts were sweating you need to insulate the grill box to the Sheetrock
