Another A/C thread... house is warmer in certain areas after swapping thermostat.

Rheem unit went out last year. AC guy couldn't get it going so they got Rheem techs involved. Not sure if it was mother board or whatever... Ultimately, they told him to rewire the thermostat which would bypass the problem. Literally new wires installed to new thermostat.
Now the rear downstairs bedroom is much warmer than rest of house, probably 6-7 degree difference. It was always 1-2 warmer but a significant change after the new wiring/thermostat. There's also a couple spots that when you walk past it's like a pocket of warmer or more humid air... not sure how else to describe it.
Any thoughts on this debacle?

This has been going on a year or just recently?

I don't see how it could be thermostat related (but I'm usually wrong).
Could be a coincidence that this started after the thermostat change. Seems like it's airflow related.

Is your HVAC system zoned? If so, maybe a problem with one or more of the motorized dampers that control air flow to the “zoned” areas of the house.
Were they buggering around in the attic/crawl space where ducts are located. Not impossible to partially crush or partially detach a duct in those instances.
Notice any difference in the run time, start & stopping cycles, of the unit after the repair?

Yes it was about a year ago but I noticed it again as weather warmed up this summer.

I had a spare thermostat, got from cleco site cheap but it's wifi etc. AC guy told me it wouldnt work on my unit b/c it's a single unit or something like that and my AC required a dual unit. He didn't use the word unit, just cant remember.

Is the new thermostat roughly in the same place as the old one?
Can you take some pictures of the thermostat settings and post them?
Get yourself a, "hygrometer" to check the humidity in your different rooms of the house. Can get one from Amazon.
Make sure your A/C isn't short-cycling. It should run long enough to dehumidify your house.
You may need to work on airflow as others have stated.
I don't know how much you've already invested in addressing the issue, but it might be worth it to have a new company come out and give some advice.

New thermostat, new temperature offset. Many electronic thermostats will allow you to adjust the displayed temperature by several degrees to reflect the actual room temperature.

This was my first thought as well.

Was it two stage before and now it’s wired for one stage only? That would explain why it’s not cooling the house like it used to. I’m probably wrong though.
