Just did a little bit of research. It seems that my understanding of returns may have been wrong.

I had assumed that the system creates vacuum pressure in order to actively pull air into the returns. However, based on what I've read in a few places, it seems that it's the positive pressure from the supply ducts that forces the air into the return. If I close the supply ducts, there's nothing creating that positive pressure so I shouldn't have to close the return ducts.
You want to try for a neutral balance with the proper amount of returns.
I just found a new supply of forks!

What if I turn the return ducts into laundry chutes? Is that a good compromise?

When you get home and are not sure how to remove the cleats just ask.  ;)
Always love when new homeowners are not afraid to get their hands dirty. You will save tons of money!!!

Thanks to your reminders, I remembered to check when I got home. There are cleats on the bottom and top so I should be able to just remove the whole duct. It's painted over, so that might present some trouble, but I could probably do it.

I also checked the basement and it looks like there are some dampers already in there, but I haven't had time to figure out what leads where.

Thanks

Wear gloves. A lot of razor sharp edges when dealing with sheet metal.

Is it possible to use a 1" filter instead of a 5"?

This is my current one which costs a small fortune: https://www.homesergeant.com/ezflex-expxxfil0024-replacement-air-filter-merv-10/

Can I use a 1" think instead?

TIA
If it's not free shipping it's not worth it.

Looking to get a split unit in my dining room as a boost to my existing central AC.

When I last had my central AC serviced the guy said that the bulk of the air was directed towards the living and bedrooms with (relatively) very little going to the dining room and kitchen which makes sense since we bought the house from irreligious people who probably spent 2 days a year in the kitchen and dining room.

Can anyone provide some insight? I'm not looking for it to snow but I would like that "aahh" factor especially when you're sitting at the table on Shabbos or while my wife is in the kitchen you shouldn't have to be sweating when the AC is on.

They range from a few hundred to many thousands...what's the difference?

Thanks

I just had a Chinese guy come and put 4 new split units for me.
 Very reasonable and good work.
Love the new ac, nice and quiet as well works like a charm bli a"h.
 Only downside is the clock is not made for a frum person, you need to set a timer or have the plug on the outside so you can put a timer or install a honeywell 7 day timer, so anyone installing one of these should factor in a 3 day yom tov or shabbos which you want it to go on and off multiple times and at different times.
Don't try to be someone else , be who you are because everyone else is taken.

Go with zoning, simple install within your existing ductwork and way more energy efficient than having a split unit and central working the same time. Check out Arzel, they were designed for retrofit.
