I am renovating a bank building built in 1923. I'd like to put in
central air but also wanted to put in old baseboards reclaimed from
another commercial building. I like the heat retention of a hot water
system, and as the building is relatively small (1100sq ft) opening a
door wide can empty the single large open space of its warm air in no
time at all.
I had hoped to get a furnace to run the the central air, and as a
back-up for heat at times, in case the boiler went out. I have a
working boiler that can supply the baseboards. I wanted to run the
central air in summer, and the boiler system in winter.
One contractor said the I should use one system or the other, but
that to use both they would fight each other. He thought it best to
run the ductwork through the floor, but the air would come out right
by the baseboards. He said the circulating air would be cooler than
the baseboards,and cause a conflict between the systems.
Instead, he suggested using an hot water coil air handler, or just
forgetting about the baseboard idea. i already had all the copper
lines installed fort he baseboaerd system.
My questions, as I have no experience with any of this:
I'd like a furnace, because I like the idea of a back-up system, more
technicians are familiar with them, and parts are more available.
I like the idea of the basebaords.
Does anyone have any opinions on this, or experience with the
reliability of using an air handler combined with hot water
baseboards?

I think the "one contractor" is either lazy or not well versed in
heating and cooling. They only way they will "fight each other" is if
you use them both at the same time. If you have that kind of cash to
operate both systems at the same time then you have more cash than
brains. :-)
What you are proposing is quite do-able. Maybe a bit overkill but you
are the one paying for it. A lot of times its hard to get the heating
water pipes and the ductwork coordinated because of unavailable room
or access.
The sky is the limit. Im sure you will find another willing contractor
that will gladly take your money.
