Should I junk my old Trane

I've been reading this forum for some time and thought it was time to ask a few questions. I've read very differing opinions on the actual Seer rating a system is accomplishing at the higher tempatures that are normal in the Houston area. My 5 ton Trane XE1000 and everything else in the system, including the gas heater, are 1988 models and have been performing fine with only a few small glitches over the years. I did notice my electric useage went up this summer along with the bill. My question is---If I have my old Trane system changed out to a new 13 seer Trane system and everything else remains the same--ducting, insulation and everthing else that goes with a system--it all stays "as is" including how we've always had the thermostat set---what kind of drop in electrial usage will I realize? 10%-20%-30% or perhaps none. I've had 4 bids for the mentioned system and I believe the payout at 20% saving would be 10-12 years.
