Hey try you a new one but maybe in a Condensing 93% AFUE
rating gas furnace this time. The 93% AFUE now days will burn
about 30+% less gas than your old one.

Yes, but the available cost data right now from the first dealer's bid
shows recovery of the higher furnace cost won't be possible within
fifteen years, by which time we will likely be out of this house.

The optimum solution seems to be a 90% furmace, as over ten years it
looks less expensive than the 80% also proposed. Here is the data,
transposed from an Excel spreadsheet:

Dealer estimate
Gross price
state rebate
net up front cost
finance cost
total furnace cost
est yearly fuel cost
5 year cost
10 year cost
15 year cost
(All figures in current dollars)

Dealer estimate for REPAIR
Gross price = $1,560
state rebate = $0
net up front cost = $1,560
finance cost = $0
total furnace cost = $1,560
est yearly fuel cost = $840
5 year cost = $7,320 (assumes re-repair every 5 yr., same cost)
10 year cost = $13,080
15 year cost = $18,840

Dealer estimate for REPLACE W/ 80% EFFICIENT FURNACE
Gross price = $ 2,600
state rebate = $0
net up front cost = $2,600
finance cost = $7 on balance we can't pay for immediately
total furnace cost = $2,607
est yearly fuel cost = $735
5 year cost = $6,282
10 year cost = $9,950
15 year cost = $13,625

Dealer estimate for REPLACE W/ 90% EFFICIENT FURNACE
Gross price = $3,400
state rebate = $200
net up front cost = $3,200
finance cost = $49
total furnace cost = $3,249
est yearly fuel cost = $653
5 year cost = $6,516
10 year cost = $9,733
15 year cost = $13,000

Dealer estimate for REPLACE W/ 94% EFFICIENT FURNACE
Gross price = $4,700
state rebate = $550
net up front cost = $4,150
finance cost = $116
total furnace cost = $4,266
est yearly fuel cost = $626
5 year cost = $7,393
10 year cost = $10,405
15 year cost = $13,533

But, Mr Turtle, perhaps you have had yours replaced
recently, and had a different experience? I would prefer
to discuss this only with folks who have actually been
through this themselves.

Thank you kindly for your on-topic remarks.
