A central air conditioning system can be one of the largest users of energy in a home. Reducing energy use related to central air conditioning can mean lower energy bills.

Homeowners sometimes buy air conditioning systems that are not properly sized. A unit that is too large will not adequately remove humidity. A unit that is too small will not be able to maintain a comfortable temperature on the hottest days.

In addition, central air systems are often set at a temperature too low or do not have any automatic or programmable thermostats to help reduce run times. Poor maintenance is common and can increase energy usage. Dirty filters can slow down air flow and reduce performance.

Proper sizing and maintenance, combined with use of a programmable thermostat, can help lower your cooling bill and ensure your system runs at its intended level of performance.
