How you can improve Air conditioning efficiency

Keep your thermostat at one temperature. It is easier on the compressor and fans to keep a temperature then it is running them at longer intervals trying to get the temperature where you want it after long periods of being off.

The faster your blower can cycle the air over the cold evaporator the faster your conditioned space gets to the desired temperature. So Periodically change your filters to keep the cycles per hour at a maximum.

Have routine maintenance done to keep the blower cleaned and checked for worn out parts.

A clean evaporator can remove more heat faster. Have the evaporator checked for dirt and blockage, filters can not keep 100% of the dirt out.

Have your outside unit cleaned, if it can not remove the all the heat it collected from inside, it keeps the heat in the system and more and more is added until your refrigearnt is saturated and can not remove anymore.
