HVAC Air Conditioning - Money & Energy Savings Tips 
  • Look for the ENERGY STAR® certified label when purchasing a new air conditioner to save the most money in energy costs over the life of your unit.
  • Look for a high Seasonal Energy Efficiency Ratio (SEER). The current minimum is 13 SEER for central air conditioners. ENERGY STAR® certified air conditioners are a model of 14 SEER or higher.
  • The cooling fins on the outside of an air conditioner help with the efficiency of cooling. These fins should have a small gap between them and should not be bent for maximum cooling efficiency.
  • Cooling fins sometimes become bent or closed by being bumped or rubbed up against. Separate the fins with a fin comb, available at most refrigeration parts stores and some building supply stores.
  • Clean the outside of the unit to remove debris such as leaves, grass, and weeds so it doesn’t block the air flow. Be sure to turn off the unit while cleaning.
  • Vacuum or blow the debris out with a leaf blower, then use a garden hose spray off.
  • An efficient system is of little use if windows and doors have cracks, allowing outside air to enter while conditioned air escapes.
  • Use a humidifier to add the correct amount of moisture to indoor air, making it feel comfortable at a lower temperature.
  • Removing humidity is just as critical to comfort as the temperature setting in the room.
  • An oversized air conditioner may do a poor job of lowering the humidity because it reaches a cooler temperature setting before the humidity is removed.
  • In fact, a slightly undersized air conditioner will be just as comfortable - if not more - than an oversized air conditioner.
