Choosing the Best Temperature for Your Air Conditioner. For many people, a temperature setting from 72 to 78 degrees is optimal, but that depends on several factors, including personal preference, energy costs in your area, and how well your home is able to maintain its temperature.How can I Make my air conditioner more efficient?
Have your AC serviced: Regular maintenance, such as replacing the air filter and cleaning the coils, can help your air conditioner run as efficiently as possible, reducing your cooling costs.How much less energy does a new air conditioner use?
Today's best air conditioners use 30% to 50% less energy to produce the same amount of cooling as air conditioners made in the mid 1970s. Even if your air conditioner is only 10 years old, you may save 20 to 40 percent of your cooling energy costs by replacing it with a newer, more efficient model.What are the energy-efficiency ratings for air conditioners?
Each air conditioner has an energy-efficiency rating that lists how many BTUs per hour are removed or “pulled out” for each watt of power it draws. The efficiency rating for room conditioners is the Energy Efficiency Ratio, or EER. The efficiency rating for central air conditioners, is the Seasonal Energy Efficiency Ratio, or SEER.
