Not to get anybodies goat, but living in larger homes with above normal HVAC systems is very expensive. Insulating homes has come a long way in the past few decades, but size is what matters. Energy companies are always going to look for ways to make money, why would we help them by using large amounts of electricity? I live in a hot state, Oklahoma, the best I ever did was upgrade my A/C to a R-410a system. This was 11 years ago and it has more then paid for itself. (My old R-22 system was well maintained) We can't rely on the energy companies to do anything cost saving for us, we must do it.
