Poor AC Maintenance adds to the power costs by reducing the efficiency of the AC unit. Neglecting to clean the coils or replacing the air filter can cause dust to pile up and accumulate inside the unit. This forces the air conditioner to exert more effort in taking in the warm air and converting it to liquid then subsequently to cooler air.

Outdated Systems Need More Energy

Moreover, air conditioner systems become outdated and obsolete over time. This requires more energy to be used in order to keep the temperature at home comfortable. That’s why unit owners may want to look into replacing the unit or central air conditioner altogether.
