Have your air conditioning unit checked every year and its coils cleaned. Dirt buildup usually causes poor efficiency.
Maintain your AC’s coolant or freon levels for energy efficiency.
Regularly clean or replace your air filter at least once every month. A clean filter can reduce your AC’s energy by five to 15 percent.
Make sure you have good weatherproofing in your home to avoid air leaks which can cause one-third of cooling costs.
