Good airflow is essential to an efficient HVAC system. Airflow is affected by a number of things, from possible leaks in your ductwork to how often you replace your filter and other factors. One possibility that tends to get overlooked is vent types. The kind of vents you have impact how air flows through your home. Here’s what you need to know about vent types and airflow.
Vent Designs
Most vents look similar. They’re square or rectangular, with horizontal slats. However, there are also decorative vents, with patterns and designs. The problem with these vent types is that they’re designed for aesthetics, not functionality.
Your home’s airflow depends on your vents being relatively unobstructed. As a rule, an effective vent should be at least 75% open space. The slats are there to direct the air. Decorative patterns are not.
Patterns mainly get in the way of the air as it flows into your home. If your system was designed specifically for decorative air vents, they’ll likely be OK. However, if you’re replacing your existing vents with decorative ones, be careful and keep functionality in mind.
Vent Materials
Some vents are made of alternate materials, such as wood or plastic, to fit with your home decor. Be careful of these vent types, since wood and plastic aren’t as sturdy as metal. To make them strong enough to replace metal vents, they need to be significantly thicker — especially for floor vents that get walked on. That thickness often means less open space on your vent, which restricts your airflow. Stick to metal vents.
They also make magnetic vent types, so you can close the vents in little-used rooms and create a seal, so air can’t leak out. This is a bad idea. Even if you don’t use a room often, keep the vents open. Closing a vent increases air pressure throughout the rest of your home. The added stress wastes energy and leads to air leaks.
