- Make sure to call professionals to give your A/C unit a regular tune up, which includes an air filter change, coil cleaning, and a check for leaks on the ducts.
- If you financially can, make sure you have a high-efficiency unit
- Double-check on your home insulation - is it well done?
- Keep the Air Conditioner at around 70-72 degrees. If you're home is insulated well, the cool air will stay in well and you won't have to worry about cranking the temperature lower.
- Every few months, replace the air filters yourself
