Can You Use Regular Floor Register For Air Return

Louvres or dampers are often attached to the back of a heat register.

Can you use regular floor register for air return. Here s an example of a giant return air grill near the floor. First let s define some terms. Keep the doors to each room open so air can properly circulate. Yes proper registers do matter.

Heat registers are vent covers that cover the hole in the wall or floor where the duct enters the room. Air registers have slatted openings in the floor wall or ceiling that a user can control using an adjustable damper. If the bedroom doors are closed and the bedrooms become positively pressurized the main part of the house sees negative pressure. You re allowed to clean your return vents yourself.

It s much better to put a return air duct in each room. They can be placed into staircase cavities stacked closets that run one on top of the other or in stud cavities in the wall. Genduct is correct in that good hvac design sizes the ducts to deliver the right amount of air to a room on the hottest design day for cooling and the coldest for heating. These adjustable louvers dampers can open or close the register to open and close the flow of air.

I usually like to see them as close to the unit as possible. The return duct or the supply duct. The return vent pulls cold air from the bottom of the room and returns it to the furnace to be reheated and returned as warm air. Proper sizing and orientation of grilles registers and diffusers may seem like such a simple thing but it s an area where confusion and mistakes are commonly made.

All ducts leak if you put the filter at the return air vent and have a leak between the gril. Return a return draws air into a return duct system with negative pressure compared to the space usually via a fixed grille but. Unlike supply vents return vents do not need to be cased in metal. How air registers work.

Typically a rolling guide or a lever on one side of the vent the damper opens or closes access to the air duct for airflow management. Vent filters can be added to your hvac system at two locations. Professionals tend to recommend a return duct filter more often than a supply duct filter but some believe no vent filter is the best scenario for any hvac system because of increased air resistance. While you should never clean most parts of your hvac system on your own you can clean your return vents.

The central return is pulling air but can t get everything back from the bedrooms. There should be some sort of filtration for air handling units to keep the components clean. You can size the ducts right run them true and clean and then choke things up with crappy registers. You lose air that you ve paid to heat or cool.
