Why is my car blowing hot air on one side and cold on the other?

Why is my car blowing hot air on one side and cold on the other?

Blend door actuators are the most common reason for the car air conditioning to blow cold air on one side and hot air on the other. They can be diagnosed with an advanced scan tool. If it does not move with the adjustments and commands, there is a problem with the blend door actuator and it will need to be replaced.

Why is cold air coming out of my vents?

Leaks in your ductwork means that cold, unconditioned air from inside your attic gets sucked into your ductwork. That cold air mixes with the warm air from your furnace, causing the air coming from your vents to feel considerably cooler than it should.

Where should return vents be located?

Does every room need a heat vent?

If your house has only central air return grille then you will notice that the return air will struggle in order to find a way back to the furnace. As a result, the pressure in each room will vary and you’ll experience uneven room temperature.

How do you tell if a vent is a return?

You can identify return vents by turning on the system fan and holding your hand or a piece of paper up. If the paper is pulled toward the vent or you feel a suction effect, it’s a return vent.

Should there be a return vent in every room?

Having several return vents (ideally one in every room, but even two or three is better than just one) creates consistent air pressure. If you have one return vent, your home is fine. Keep the doors to each room open so air can properly circulate.

Should return air vents be open or closed in winter?
