This system keeps your home comfortable all year by circulating warm and cool air. Okay, that seems pretty simple. Nope, not really. As important as other parts are, the fresh air intake vents are what keep the air in your home safe for you to breathe.

Intake vents for fresh air are how your home gets clean air from the outside. They keep dirty or toxic air from coming inside. The furnace is normally in the basement, and there is an air duct that starts there and goes to an outside vent.

Why Fresh Air Intake Vents Are Helpful

Fresh air intake vents do more than just keep the air quality inside your home healthy by stopping carbon monoxide and pollutants like pollen, mold spores, pesticides, and other chemicals.

  • Reduce the amount of dust in your house.
  • Boost your furnace’s performance and make it last longer.
  • Windows and doors should let less air in.
  • Give your home extra air to make up for the air that your range hood vents, bathroom exhaust fans and clothes dryers take out.

Taking Care of Your Fresh Air Intake Vents

Even though fresh air entry vents don’t need a lot of care, they do need the following basic things to keep working right:

  • Changing hvac filters daily will help keep dust and other harmful particles out of the air that flows through your home. Every six months at the very least, you should change this setting. Three times a year if you have animals.
  • If you want to, you can use a hoover or a cloth wet with water, not cleaning products, to get rid of any dust or dirt that has built up on the event’s face.

If it’s cold outside, you might not see why you should let cool air into your home when you’re trying to heat it, so you can close off the doors. This might cause a risky situation. Inhibiting the vents creates negative pressure, which can lead to the backdrafting of harmful gasses like carbon monoxide.


Does the Type of Furnace Matter?

Usually, house furnaces are either conventional or high-efficiency. A fresh air intake filter is needed for a regular heater so that it doesn’t pull air from places in the house that aren’t conditioned and have bad air quality.

 Basements, crawl areas, attics, and even dryer vents are covered. To refill the air that is inside, the filter pulls air from outside the house.

In a high-efficiency heater, a filter for incoming fresh air is already built in. In this case, adding more fresh air intake filters or heat pump system services will help fight the wetness and condensation that the furnace’s burning operations produce.

Your home may have one or many fresh air intake vents, depending on how old it is and how big it is. One vent is generally enough for older homes because outside air can get in more easily through cracks and holes.

 It’s important to have several fresh air intake vents in newer homes because they are almost sealed because of the extra insulation they use.
