Default heating/cooling system not great?

Im just curious if its just us. We have a Nile. AC has been going for days and the top floor is still smouldering. We close all the the vents on the main floor/ basement/ and any rooms we dont spend time in just to gets some cool air moving in 2 bedrooms. It doesnt seem to push much air out of the vents. It feels cool but very weak. I tried removing the furnace filter but its the same.
Same thing reverse in the winter. Bedroom is a meat locker when the rest of the house is warm.
Any suggests?

if you close too many vents your ac coil in the furnace can freeze up... i had to keep open the main and second floors.

Define smouldering, what kind of temps do you have? It almost sounds like you have a balance issue. This might not be the right term but are the main vents from the furnace trunk open on both sides? Are the flaps open at the registers? You may need to put your hand in? What direction do you face, do you have your blinds open or closed. We installed black out blinds on the second floor and it has made a huge difference. We keep our system at 25 during the day, usually yielding 26 or 27 during the day however once 7 hits we lower to 24 for the night and the virtually the entire house becomes 24 within an hour aside from the basement which waivers around 20-21, once the sun comes up because we face east and the instant temp climb starts at 6:30 AM, anything lower than 24 will have the system run no stop all day.

Is your basement finished? If no you may have massive air loss at the rim joists, seal those up if you can.

another 'cool' robber is holes in the duct work

use foil tape on every joint you can access

If it's a new build it may be worth having an HVAC company look at things. There are different fan speeds that both the AC and Heat can be set at. If you're set way too low that could be an issue.

Also - make sure your filter is clean!

Further to G2K's point I did that in my basement and once you actually start going you realize how many holes you have in your ducts, elbows and the trunk of the unit was a sieve, the air loss is significant. I went through three roles.

On a day like today, cloudy, raining but hot and muggy my home is very well balanced, temps match virtually throughout the house, basement is cooler but that is because the basement is properly sealed.
