Keeping this in view, what are the big vents in my house for? Your Return Vents Are Responsible for Air Pressure The excess air needs somewhere to go, and that spot is the return vent. The return vent is usually bigger than your supply vents because it’s how the air handler sucks air into the HVAC system.Furthermore, what is the difference between a register and a vent? Heat registers are vent covers that cover the hole in the wall or floor where the duct enters the room. Louvres, or dampers, are often attached to the back of a heat register. A grille has no damper to control air flow, so air is left to flow freely. Grilles do not have the damper normally found on registers. Moreover, is it OK to cover air vents? You could mess with the air flow. Just because you cover the vent, it doesn’t mean your HVAC system knows that. It will keep pushing air to those vents, and if they’re closed, you could cause a buildup of air pressure and insufficient airflow which could damage your system.Are return vents necessary?Not having enough return air vents is an inefficient way to circulate air through your home. Similarly, if you have vents in every room, ensure to keep them all open. Closing vents in unused rooms increases pressure in the air ducts and puts the whole system under strain.
