I'm replacing my oil furnace and I'm deciding between a single stage or a
2
stage furnace w/ variable speed fan. I was just wondering since my house
is
so old, will it make any difference to get a 2 stage furnace w/ variable
speed
fan? it's about a $1000 dollar difference. Thanks

How much money will you save each year?

I wouldn't spend an extra $1000 for a more complicated furnance.

The $1000 difference he was quoted sounds way high too. The two
stage is essentially a gas valve that opens part way or full.
The variable speed blower, if it's being compared to a regular,
non-ECM blower, there is some more substantial difference there,
but you can buy those furnaces retail with maybe a $300 delta.
