Noisy furnace 😪😪😪

We bought a 30 yrs old house with high ceiling. All looked good, until the ac started working, I feel like I am in an industrial plant. The furnace is extremely noisy, the air is pushed like there is a waterfall behind it. Additionally two windows are popping half day (most likely direct sun and heat). The dryer and dishwasher are also noisy and unfortunately the dryer is downstairs where I spend most my day. There is crazy eco on the house entrance, which is also adjacent to where the furnace is located. We already put furniture and a large bookshelf, it did not help much. The house is making me very miserable. Your advice is appreciated.
