They came in this morning and they were like "yeah we're going to need to put in a second return vent in the floor" which was kinda off putting because I didn't know it was gonna have to go on the floor, so I was kinda uhhhhhh but do what you gotta do about it, then they came back and said they'd do two smaller vents instead, then they came back and said they'll just widen the existing 16x20x1 return to a 16x25x1 and I was like yea i mean whatever works for me as long as it's set up how it's supposed to be, and they were like yeah it'll be fine like this
Y'all the lying machine says that's basically good for 800cfm and maybe "up to 1000-1200cfm depending on how the system is engineered" but it needs like 1200cfm by design. That's half the reason we were paying to replace the existing shit before it breaks, it's been operating with half the necessary airflow for 10 years
Anyway idk I guess I'll ask them what's up with that, but like, fuck I am tired and unqualified to be dealing with this
update: i have spoken with the hvac guys and they too are unqualified to be dealing with this, they said a mysterious guy on the phone with the license was the one who told them they just needed to add 5 inches of space to the return vent, but like, yeah, that conflicts with all the other information I have and also the guy who came out to do the quote said it'd need another return vent
if the llm is being accurate at me my understanding is it needs something like another 14x20 vent
clippings everywhere is probably worse than grass that's a little taller than a football pitch
it's uh, a bit taller than football field grass, I should have mowed like a week ago probably but like, effort, also it's variably either too hot or too rainy or both
I just don't imagine they'll be able to clean up all the shit i'm seeing even if they're trying their best and it's in part because the grass is kind of high but idk I don't know their work so maybe they've got it figured out
I think they're coming back from lunch now so I get to go ask why it seems like they're severely fucking up with this return vent deal (again, according to what i'm being told by the llm)
but I also mentioned to the guy who came out to do the quote something about having a media filter cabinet because I like the idea of actually being able to use one of those fancy high MERV filters they sell but which fuck up literally everyone's HVAC systems, and my understanding is one of those would effectively reduce the needed airflow, so, like, I dunno, maybe they're doing that
it's just if all it is is going from a 16x20 to 16x25 return vent the llm's telling me that's just half a square foot of surface area added and it needs 4 square feet total to handle 1200cfm, which would be like, yeah, a whole extra return vent
also if you take the clippings from your yard you're robbing your yard of precious nitrogen
