How do you redirect air vent flow?
When it comes to accurately redirecting vents, a vent deflector is an ideal choice.

Why does air lodge in the condenser?
Air will remain in the condensers when the receiver liquid temperature is higher than condenser liquid temperature. This can happen when: The receiver is in a warm place. Cooling water temperature is falling.

Why is my heat blowing cold air?
When a furnace only blows cold air, there’s a chance the heater could have overheated. But don’t worry, this usually doesn’t mean the unit is broken. When the system overheats, there’s a safety feature that shuts the system off. This is a good thing—it could prevent a fire, carbon monoxide leak, or even an explosion.

Why is cold air coming out of my vents when heat is off?
