The two BTU ratings are input and output. With a 61,500 input, your furnace
in not designed to deliver 80% efficiency. You have less than 75% with a
45,000 output. Whatever the rating, you need someone competent to service
the furnace.

I'm in a suburb of Rochester. Want me to drive over, and
take a look? Yeah, I know. Everyone on the list says I'm a
total hack. I know, I know.

I'm located in Rochester NY for the record, and I do have
central
air.

There are two ratings on the furnace, one is 45,000BTU and
the other
is 61,500BTU, but the furnace was made in Quebec and
everything
written on it is in FRENCH! Online translators were no help
in
figuring out what the tag says...

Then you have to find a person who knows French. Shouldn't be hard.
If he knows a little bit about furnaces, that would be good too, but
probably not essential. Take what he tells you and post it here.

Boy, it sure doesn't seem right. I have a 10 year old, 80% efficient
60,000 btu Armstrong furnace for my 1500 sf house in northern Ohio. It
puts out 115 degree air at the register closest to the furnace. The
double walled flue is hot, but I can place my hand on it. The plenum is,
of course, quite hot. I insulated it with high temperature fiberglass.

The house is well insulated with ducted returns and easily heats all
rooms over 70 degrees in 15 below zero weather, and only runs about half
the time under those conditions.

For starters, is the rerun air ducted, or is it an open return system?
