A number of people across Australia rely on their Heating, Ventilating and Air Conditioning (HVAC) units to keep their homes and offices comfortable. Any building with central heating and air-conditioning will feature a series of openings that transfer air to and from the furnace and the air conditioner. These openings typically comprise air vents, air grilles and registers. Improper installation or the use of inferior-grade products could end up compromising the effectiveness of your unit. This is why it is imperative to purchase your units from an experienced and reputed supplier. Not only will these insulation suppliers offer a diverse range of products that suit your needs and your budget. They will offer superlative installation services too.

 

What Are Air Vents?

Providers of air conditioning supplies will know the differences between air registers and grilles. But, many users will not possess this knowledge. Knowing this might be useful when you need to describe a problem to the repair or service technician. All registers, grilles and returns are vents. Thus, a vent is simply a term that describes all supply and return air sources connected to the HVAC unit. In some cases, you might have the option of installing air registers or decorative grilles interchangeably. In this scenario, you will need to consider whether you need adjustable vents for improving the airflow. In addition, you will need to purchase a vent from an insulation supplier based on the dimensions of the air duct. Failing to do so could leave you with a vent that does not suit your unit.

 

What Are Air Grilles?

The vent covers placed on top of the air ducts denote grilles. They derive this name from the vents, which typically have a grille design. This design serves to keep large objects and rodents from entering the air duct system. A typical grille will feature a flat metal vent attached to a wall or the floor of the building. In many cases, the grill will comprise a lightweight metallic material. Air return grilles help in pulling air back into the HVAC unit for reuse. Inferior-grade grilles could lead to the escape of air. Consequently, your unit would consume additional power to cool the building effectively.

 

How Do Air Registers Work?

Air registers often feature slatted openings in the floor, wall or ceiling. Users control these openings with adjustable dampers. By controlling the rolling guide or lever placed on the side of the vent, the user will be able to open or close the damper. This will, in turn, open or close the access to the air duct for airflow management. It is worth mentioning that these openings deliver hot or cold air into a given space. Unlike air grilles, they do not bring air back into the HVAC unit.
