2004 Kia Sedona running hot. Thermostat almost to H level

I have a 2004 Kia Sedona. I have had the compressor replaced about 3 weeks ago. Now the thermostat is going to H (hot).

I had a checked by a mechanic who checked the radiator pressure??? and added more coolant. That was last week. It ran fine for a week but is now running hot again.

I drove it for about 30 minutes today and it was starting approaching hot.

Any ideas as to what I should do. Car has about 177,000 miles on it and other than this issue runs fine. Could it have something to do with the compressor replacement?

Today it is close to 100 degrees in Maryland.

Any help anyone can offer this clueless female would be great.

By reading that it's got close to Hot on several occasions on a stock gauge could point to the head or head gaskets. My 05 V6 Sedona runs right under the half mark and the highest I've seen it is exactly on the half mark and only reads as a 30 degree difference on a OBD scanner 185 to 213 seems like the gauge would move more for 30 degrees and 213 should be a little above the half mark.. Sadly you should never trust stock gauges just use them for a reference! EVERY TIME I've seen a coolant light or oil light it has been to late. Most vehicles only use1 fan when the AC is off and uses 2 fans when the AC is on, but reading this "has had the thermostat and fan replaced in the effort to stop it from overheating" makes me wonder how close and how many times has it overheated and it kinda sounds like it could possibly need a head gasket and the head shaved because it has aluminum heads that warp VERY EASILY. I wouldn't think the AC compressor is getting so hot it Could make the motor its mounted on the side of the motor I'm pretty sure that' would be impossible. Air in cooling system is getting to be a more common problem but my 2005 kIA Sedona with a 3.5 liter and it just needed the overflow resivor and radiator topped off twice the first time maybe a quart and maybe a half quart the second second time. The AC quitting sounds like it got hot enough to burn up and also suggest that 2nd fan.
