Here in Florida, we rely more on AC for most of the year. Apart from a properly sized AC unit, and the ducts being run correctly, the next biggest factor is insulation. When they built this house, they did NOT spare the insulation. It's critical in maintaining the temp, so the AC does not have to work so hard to maintain cooler temps in the home.
Another important factor is the filters, especially CLEAN filters. During heat waves, I have been know to swap out the good filters, for the cheaper filter furnaces, because of the higher air flow. Of course, one must replace the cheaper ones more often. When temps return to a more normal range, then I'll put the higher quality filters back in. The higher the quality, the more they filter, the more they restrict air flow. Dirty filters restrict air flow too.
For those that turn off their AC, or set the temp a bit warmer when they leave the house for work, or when they're not home, DON'T do that. It will end up costing more in the long run.
If your unit is 10 years old, or older, try to replace it with a more efficient model. Yes, it makes a difference in the electric usage.
