AC Can't Keep Up With the Heat in Columbia, SC

The system runs nearly all day during Columbia's peak summer stretch and the house still sits a few degrees above setpoint.

What usually causes this

A system that's undersized or aging and was already near its limit before this summer's heat
Low refrigerant or a dirty coil quietly reducing capacity over time
Poor airflow - a blocked return, closed vents, or ductwork losing cooled air before it reaches the room

What to do before someone arrives

Check that supply and return vents throughout the house are open and unblocked by furniture or rugs
Note whether it's the whole house or just one area - a single hot room points at ductwork or a zoning issue rather than the equipment itself

Questions people ask

Is this just because it's an unusually hot summer?

A healthy, correctly sized system should still reach setpoint on Columbia's hottest days, even if it has to run nearly continuously to do it. If it's not getting there at all, that points to a real capacity problem rather than just the weather.
