What Is the Purpose of a Return Air Vent?

Return Air Vent Purpose

Most people don’t know a great deal about how their heating and air conditioning systems work. They know that they can switch from heating to cooling and change the temperature range. They also can tell if the system is not performing at a satisfactory level. Many are aware of the return air vent. Still, some might wonder, “What is the purpose of a return air vent?”

3 Things Your Return Air Vent Does for Your AC System

The answer is not as straightforward as one might think because the return air vent actually fulfills several purposes. It uses low pressure to help collect and circulate the air throughout your home or business, maintains optimal air pressure within the ductwork, helps to save on energy costs, and traps airborne particles and contaminants.

1. Maintains Air Pressure

We all hope that our homes have efficient, properly sealed heating and cooling systems. While few houses are truly airtight, most come very close using new construction methods and insulation. The supply vents in the heat and air system push air into the home after cooling or heating it. All this air needs to go somewhere to keep the air pressure from building, and the return air vent helps maintain this balance.

2. Reduces Energy Costs

An efficient return air vent can reduce energy costs by recirculating air that is at or near the desired temperature back through the system. By capitalizing on the already heated or cooled air, the system actually works “smarter” and does not waste energy reheating or recooling. A malfunctioning system might misuse energy working harder than necessary.

3. Traps Airborne Particles

Normally, next to the return air vents are changeable filters, which are the same filters we encourage customers to replace every two months at a minimum. Some systems have additional filters inside that require professional technicians to change, but all have filters that should be changed regularly to maintain indoor air quality.
