Mine was struggling yesterday evening and noticed it was blowing warm…. Shut it down for about 15 minutes and it seemed to start blowing cool again. Checked the temps with my infrared thermometer and it was between 62-66 after it got dark but been more like lower 70’s in the heat of the day
Does sound like you may have had a slightly frozen evaporator coil, indicating you could be a little low on refrigerant. But you should have a cooler temperature than the low 70s, during the day, exiting the nearest supply register to the furnace/air handler. A temperature split of 16-20 F would be considered, to a tech, acceptable in this heat.
I just measured my nearest supply register with an infrared thermometer (5:50 pm) and it’s 57 F (probe thermometer would be more accurate). My split right now with the return grill is 16 F. Attic temperature is 121 F - those supply ducts are picking up heat from that hot attic.
But I agree do the simple things first, clean the outside condensing coil, make sure you have a clean, and not a high MERV 1 inch thick return grill filter, and see if that helps.

I’ll have to run to Home Depot and get some of that coil cleaner soon.
I don’t think it helps that my unit is on the side of my house that gets pretty brutal afternoon/early evening sun
