Your engine may not be reaching operating temperature. This could be from a faulty thermostat sticking open. A thermostat should open and close as needed to allow the engine to get to and remain at the most ideal temperature. If it sticks open, often times the engine never gets warm enough. As a result, the coolant flowing through your heater core is not hot enough to produce hot air.

Have this checked first. Good luck.

This could either be that your engine is low on coolant, or the heater control valve is stuck in the cold position. We would have to look at it determine the exact cause.
