Then I guess I'm never replacing mine. It's not like HVAC technology has advanced much in the past 100 years, beyond the switch to R-134A from Freon. Most tech advancements are made on the thermostat-end. The system itself is ridiculously simple; usually just 3-4 wires (A/C on/off, Heat on/off, fan on/off, and sometimes a separate power wire).
