Yes, there are several things you can do to reduce monthly expenses related to air conditioning.
Change your filter(s) regularly. An unclean filter makes your system work harder.
Use a programmable thermostat and set it between 78-80 degrees when you are not home. For example, setting your house thermostat from 73 to 76 degrees can save you as much as 15% on your monthly electricity costs.
Keeping the fan set to “Auto” can also save up to $25 per month.
