Given the prior formulas you have worked with for estimating annula heating and air conditioning costs,

$1)$ What will the home owner experience in annual heating fuel bills with the more efficient

furnace?

$2)$ What will the home owner experience in annual air conditioning costs with the more efficient

air conditioner?

$3)$ How much money totally will they save in heating and air conditioning annual fuel consumption

$($yes$,$ I just made you figure out the annual coast for the less efficient equipment by asking this$)?$

$4)$ Since the mandated upgrade to more efficient equipment is NOT voluntary, and will be required

if when the old equipment fails, there really isn$$t a $$payback$$ issue here...this is not a voluntary

decision. So$,$ what could you suggest the federal government offer to the homeowner to make it

hurt less financially to install better equipment to be in compliance with the new efficiency

guideline? Or$,$ if you$$re not feeling benevolent, what could the federal government do to

panelize the homeowner for not installing the better equipment?
