Air Conditioning
- Don't set your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
- Check the air conditioner (AC) filter each month, and clean or replace it as needed. Dirty filters block air flow through your cooling system, increasing your energy bill and shortening the equipment’s life.
- When buying a new AC unit, look for a SEER (Seasonal Energy Efficiency Rating) of 13 or higher on central systems and the ENERGY STAR label on room units.
