Look on your electricity bill to see your kW/hr charge (My EasyMax rate from most recent Enmax bill has two, so I averaged it out to 0.052 per kW/hr)

kW charge X kW calculation from above = cost to run unit per hour if ran continuously.

Basically, my newly installed Trane XR13 A/C (13 seer = about 20 amps average) will cost me 0.27 cents an hour to run. On the day it was installed. it ran for 3 hours. I expect a hot day like today it will be more like 6-7 hours. And of course, the charge rate may change throughout the year, so be sure to check that every so often.

Also, for what it is worth, I paid $3500 with tax to have it installed in my 2000 sq/ft, 2 level infill, and while I don't recommend the company who did it (issues that they have to come back for... grr!), I feel that the Trane model and overall cost was worthwhile.

I was also told years ago by an HVAC company to block off the upstairs air return vents in the summer, and the basement ones in the winter, so that hot air isnt drawn back (in the summer) and cold air (in the winter) to the rest of the house.

Currently have the house set to 21C and enjoying it!

There are 1000 W in a kW. Also, I don't have a bill with me but I think some of the other charges on it are affected by how much energy you use.
