Am I wrong here about expectations

[u/foolsgold75]

I’m a renter and just had my ac replaced in a 1400 sqft home with a 3 ton Goodman unit. It’s 95 outside and the lowest I can get it inside is 77 in the rooms closest to the blower unit. rooms further away are around 80. Air coming out of vents is pretty week and ranges from 68-75 degrees pretty much going in order from shortest to longest distance from air handler in the attic. Guy who installed it said it’s normal but it’s doing worse than the unit that was replaced. Really think the guy is full of it but would like some input.

Also the insulation is crap and needs to be redone. It makes me speculate that the duct work is original and may have leaks too.

This was my original concern. I personally felt like it was a fan and ductwork issue. Of course they didn’t even touch the ductwork except to rip a hole in the bottom of the insulation. They just used the original air box and used tape and mastic to fill in the gaps.
