FAQ

AC Running All Day Questions

Is it normal for AC to run most of the day in the summer?

Some extended runtime during peak Louisiana heat is normal. A system that runs continuously and never brings the temperature down is not.

Could bad attic insulation cause this?

Yes. Heat gain through an under-insulated attic adds load the AC has to fight constantly, which can look like a system problem when it is really an insulation problem.

Does an oversized system run less?

Not necessarily comfortably. Oversized systems can short cycle instead of running efficiently, while undersized systems run long and still may not catch up. Correct sizing matters more than "bigger."
