Strange odors: Musty, burning, or chemical smells emanating from the vents.
High energy bills: A sudden and unexplained spike in your electricity costs often indicates an inefficient or struggling AC unit.
Frequent cycling: The AC unit turns on and off more often than normal, failing to maintain a consistent temperature.

If you notice any of these symptoms in your Decatur home, whether it’s a bungalow in the established neighborhoods or a newer build in a growing subdivision, it’s time to consider professional AC repair.
