Estimating my electric bill if I add A/C

Factual Questions
1

I’m thinking of installing central A/C for the first time. Is there a way to estimate how much higher my monthly
electric bill will be if I run a 3.5 ton A/C for six hours a day? I hope to only use it when the inside temp is 84 F or above.

According to my bill, I’m paying $0.16723/kWh plus a 10% surcharge fee.

Thank you!

That works out to about 6300 W or 6.3kW. So assuming a 30 day month : 30 x 6 x 6.3 x 0.16723 x 1.1 = $208.6

This is assuming that the AC runs continuously for 6 hours, in fact it may not do so.

Thanks, am77494. Does it use electricity to go on and off, or am I only charged for the
time it’s actually running?
