New heating system advice.
So I bought a new home in WV six years ago. It came with a 57K btu propane heater, which heats rather well and a 10 Seer 3 ton Central AC. However, the price of propane has jumped to $3.10/gal and our estimated heating cost for next year are over $4k. Cost of electric in our area is .095/kw.
After crunching a bunch of numbers I have settled on a Goodman 3 ton 2 stage 16 seer/9.5 hspf system. The question I have is: the old unit was rated at 57K Btu and the Goodman is only 36K Btu, is this going to heat my home or do I need to be looking at a bigger unit?
