Are you running your air conditioner at its optimal performance level? If not, this could easily result in high energy bills and reduced efficiency. It’s important to have your cooling equipment regularly serviced by an experienced technician or contractor who will know exactly how to diagnose and fix efficiency issues. However, there are some basic procedures you can do yourself to prevent high energy bills and ensure your system is running effectively.
Outdoor A/C component: Check that your outdoor condenser’s airflow is not being blocked by any obstacles or obstructions. Make sure that the unit is not covered by any bushes or plants that could disrupt airflow. There should be at least 2 feet of clearance on each side of the condenser and 5 feet on top. Inside your outdoor unit is the condensing coil. This coil 
should always be kept clean. It’s quite easily accessible from the outside. Cleaning should be done at least once a year. Make sure that your technician or contractor tends to this during every service inspection.
Inside A/C component: Just as your outdoor condenser coil needs to be cleaned regularly, so does your indoor evaporator coil. The evaporator coil becomes damp with usage and therefore attracts dirt, dust and mold. Make sure that your evaporator coil is cleaned effectively to protect your family from potential health risks as well as to ensure savings on high energy bills.
Thermostat, fans and windows: Another way to reduce high energy consumption is by raising your thermostat to about 78-80 degrees when you’re away from the house. Run indoor ceiling fans in conjunction with your air conditioner when you’re at home to allow the fans’ wind-chill effect to help with cooling. Windows are another reason for substantial amounts of unnecessary energy usage. Installing shaded window blinds or solar shade screens will prevent sunlight from streaming into your home and adding to the cooling load of your home.
