Hi;

I am buying a house for rental property. It currently has a 2 year old
13 seer 3.5 ton Carrier Central AC System that is self contained and
sits outside. There is a huge duct that comes out of the unit and
enters the crawl space and cools the house.

As for heat, the house was made in 65 and has electric base board heat
and I would like to convert to gas forced air, or maybe even a boiler
system for water that heats the floors. What are my options? If I was
to install a natural gas heater, could I hook into the AC Duct under
the house? I hate to think what the electric heat is going to cost
with base board.

Any suggestions would be welcome.

Of course, no one has asked you where the property is. If in FL, who
cares, since the baseboards will nearly never run. If in Michigan,
quite a different story.

I am in WI, where it would be a big deal, but no one here would have
put in a central cooling system and ductwork, we would just use window
units for the limited cooling season.

I have been a landlord for several years. I offer this:

If it is not unusual for other properties in your area to have
baseboard heat, don't spend extra money doing a central heating
system.

Check with your local utility and see what the electric bills were
last winter. If they seem really high, you might have to spend money
on a central heating system to be competitive with other rental units
in the area. A natural gas or propane unit tied into the existing
ductwork (or replacing the existing air handler) will be the least
expensive way to go, but it won't be "cheap", especially if you have
it installed by a competent, licensed contractor.
