Can I add vent to basement intake?

My basement is very cool in the summer,like most people's. Can I add a vent into the cold air return to suck all the cold air from the basement when I have the setting to fan?

Someone told me that this could bring the hot water tank fumes throughout the house. I dont see how this would be possible. The house is les then 10yo.

It can create a situation where the air pressure in the room where the water heater is can be low enough to create a backdraft and pull the exhaust back into the house.

Do you not have any cold air returns in the basement? You do have vents, right?

No air returns in the basement

There are no air returns in the basement. Just air vents to keep the basement cold, which are shut off. So can i put one on the side of the Furnace to suck in all that cool air?

If your gas appliances (WH, furnace, whatever) are in the basement...it would be a bad idea.

I'd be hesitant to do this myself, I'd want an HVAC contractor to think it was a good idea first.
