[QUOTE="71buickfreak, post: 2834564, member: 8373"] That all depends on the quality and efficiency of your old system vs the new. HVAC systems are built to live for about 20 years. mid 90s is certainly coming up on that. There are many older systems- 30+ that are still going, and they can work just fine if they are regularly maintained, but they are not built for that. it also depends on the type of system you have, a heat pump uses the AC unit in reverse to create heat rather than an electric strip heater or gas furnace. The heat pump is very efficient, but when it gets real cold, the auxiliary heater comes on (electric strip) The first thing you should consider are drafts. replacing door strips and sealing the windows can make a huge difference that a new HVAC won't fix.
