Yes you can but why would you want to preheat the air, it should already be around room temperature.

You have an electric forced air furnace and central air. why does the central air fan run when furnace comes on?
You must have a heat pump with electric auxilliary heat.
How do you heat homes on slab?
No different than any other house. Heat ducts can be put into the slab when it is poured or they can be run through the attic and walls and a forced air furnace is used. Wall furnace, baseboard heat or they could have radiant heat in the floor.
How does an attic tent help with insulating a room?
Insulation helps to prevent heat loss. The attic tent covers the entrance of the attic to prevent heat from escaping. As a result, one will save money on their electric bill by using an attic tent, and it is also eco-friendly.
Does a forced air furnace have a heat exchanger?
Yes,It depends if it is gas fired or electric.
What gauge wire is used for electric furnace heating elements?
normally 8 gauge wire is used for electric heat furnaces.
Heating coils made of which material in a furnace?
If you mean an electric furnace then normally it is nichrome. a heating element in a heat strip is made of what type of wire
If you disconnect the tankless water heater on your furnace and have an electric hot water heater installed will there be a problem when the furnace runs to heat the house?
Not if it was disconnected properly
Can you cover your cold air return for more heat?
No You can't cover the return air. Because the limit switch in the furnace will trip. If the furnace was working ok before I will check for air leaks in the return air. Good luck
Convert oil furnace to electric?
"Converting" an oil furnace to electric will not be economically practical. You'd be far better off getting a "ground source heat pump" and having someone install it for you. They're much more efficient than the older style electric heat that uses resistor heating elements.
What does it mean when you turn the heat on and it blows out cold air?
Not knowing what kind of furnace you have makes answering this difficult. What type of furnace do you have (gas,electric, oil) and how old is it?
If the water is shut off will the furnace work?
If you have hot water heat or steam heat, it will still work. Gas or electric heat has nothing to do with the water system.
Do the electric furnaces operate the same as a gas furnace?
The simple answer is yes it produces heat and is distributed to the rooms in your house; unless however, you are using electric baseboard heat which works on convection, or electric radiant heating panels.
