Monthly AC Operating Cost Calculator

How much does it cost to run AC per month in Florida?

Monthly AC operating cost depends on system size, efficiency, daily runtime, number of cooling days, and your electric rate. Florida homes can vary widely because thermostat setting, sun exposure, ducts, and humidity all change runtime.

Calculator Inputs

Monthly cost = tons x 12,000 divided by SEER2 divided by 1,000 x runtime hours x days x electric rate.

Monthly AC Operating Cost Calculator FAQs

Why is my AC bill higher than the calculator?

The calculator estimates compressor energy only. Whole-home bills also include lights, appliances, pool equipment, taxes, fees, and plan-specific charges.

What runtime should I use?

Use the best estimate from your thermostat or smart-home app. In hot months, many Broward systems run several hours per day or more.

Can maintenance lower operating cost?

Maintenance can help protect airflow and heat transfer, but savings vary by system condition.
