Central air not cooling (or maybe it is?)

I purchased this home in Nov. of 2014, its a old house built in the 50's but everything from the floor joists and up is brand new, including the HVAC.

Entire house is 1600 sq. ft., estimating basement + first floor is 1100 sq. ft. and the 2nd floor is 500 sq. ft.

My air units are good for up to 1200 sq ft each (I have 2). One unit does basement + first floor, other unit does 2nd floor.

First floor + basement = 12 air vents
2nd floor = 5 air vents

So my issue is, the 2nd floor heats and cools like a charm. Air comes out of the vents like a jet engine. However my first floor/basement is where my family spends 90% of the time, so less air gets pushed around to each of these 12 vents. These last 4 days I just started using the air conditioner in the evenings... my thermostat (with windows open) will show it being 70-75 degrees from morning until early afternoon, and then once the sun gets over the house is when it jumps up to 80. Around 78 degrees if when I shut the windows and cut the AC on. The AC cuts on around 2pm and is set to 77 degrees, and never shuts off. Keep in mind the high temperature from each of these days is no higher then 82.

Last night I got up around 2am and to look at the thermostat, and it showed 77 degrees (AC was still running) and set to 77... 10 minutes later I look at the thermostat and it has jumped up to 78! Keep in mind by this time the temperature outside was in the 60's.

Im a first time home buyer and no very little about home maintenance... but I know from living in an apartment the last 10 years I had to call the maintenance guys out to add more freon about once a year to my AC. I'm seeing online that you should be able to go to the outdoor unit and touch the larger copper pipe and feel it "sweating"/condensating from the pipe being cold in the hot temperatures of the sun. My pipes feel a little moist but I wouldn't consider it enough to actually drip off of the pipes.

When new air units are put in do they normally top it off with freon or is that something that is expected of the home owner to add after installation?

I'm not quite sure what else to do... what I was thinking about trying to BLOCK air flow in the ducts to rooms I don't need AC in... I'm never down in the basement and have a dehumidifier on about 80% of the time so that's one I can close, the downstairs bedroom and living room both have ceiling fans which I don't really need the AC in. I'm talking about more then just covering the vent, more along the lines of pinching the air duct arm that flows to these vents in the rooms the air flow is not a necessity in.

Any recommendations for me? Thank you.
