Where does cold air come from when the heat is not on?

The other day, we noticed it was drafty (our house is cold anyhow in general) and I found that cold air is coming out of the air vents when the heat is not on. When the heat is on, the warm air blows, but otherwise, it’s blowing cold air – it almost feels as if it’s A/C air.

How does cold air return to the furnace?

Coach Tim explains heat runs and cold air returns to the furnace – something that is essential to tackle in your renovation project. Components of a forced air system: a fan draws air from the house into the system through return air vents.
