I often get ask about equipment efficiencies and cost to operate. Question I hear a lot are whether to buy a higher efficiency heat pump or furnace and how long is the payback or whether to use a furnace/AC or heat pump. With all of the different energy sources (Elect/NG), ratings (SEER,COP,HSPF,EER), different climates, and varying cost of utilities(tiered pricing,service charges,taxes,fees), tax credits, rebates, how do you come up with a straight answer? So the answer usually tends to be; it depends.
Wouldn't it be nice if there were a calculator for this. Just plug in utility cost including service charges, taxes, and fees, your location, and equipment efficiencies and ratings, credits, rebates, and then voila, there's your answer.
Anyone know of such a calculator?
