High efficiency furnaces are trouble-free for the first 7 years or so but
then furnace hell begins.

I paid $420 to have the draft inducer replaced on a 9 year old furnace.

One of the vacuum safety switches also failed but that repair was only
$140.

So any fuel savings is easily offset by higher initial cost and huge
repair bills.

You can usually get a Service Contract-mine is through the Gas Co--and it
covers all the components that you mentioned. My only problem with a 6 yr
92% was the flame sensor. Other than the contract cost my out pocket $$$$
was Zero. Actually, you saved money if these were the first costs you've had
in 9 yrs vs paying for a contract over that time frame.
Gas company periodically sends a flyer on how you're doing relative to the
average users and to neighbors. My fuel costs are only 4% higher than the
most efficient and way better (lower) than all the others. So fuel cost
savings is a major factor.
