Mo@#$%^&* ..need A/C and Furnace replaced

New system going in here too. The Trane 3 ton a/c with 50kw of electric heat in top of air handler was new with the house in 1991. Energy guide sticker on it says 8. Today thats probably closer to 5. Even though we burn about 40 dollars per month in propane in a vent free gas log fireplace on winter days, the electric bill average for the year is above 300.
New unit is a 3 ton heat pump with only 10KW of electric heat. Energy guide/SEER rating is 16. I know the new unit w/ scroll compumper wont live or run trouble free for 30 years like this Trane has. I'll hope for 12 years with minimal trouble.
