Ventilation Systems

Healthy indoor air requires a proper home ventilation system to circulate fresh outdoor air into the home while sending old air outside. This ventilation is important to reducing indoor air pollution, mitigating the growth of mold and mildew, and regulating indoor air temperatures while ensuring energy-efficient operations.

Air ducts, vents, fans and HVAC appliances all play a role in this ventilation system. Maintaining and upgrading this ventilation system is an important aspect of caring for your home. It can also save you money on utilities when you invest in energy-efficient house ventilation systems.

Ventilation Systems

What Are the Types of Ventilation Systems?

If you’ve never had to install or service your home’s ventilation system in the past, you may not understand exactly how it is designed to work. Residential ventilation systems typically fall into one of three broad categories:

  • Natural. A natural ventilation system consists of manual openings that facilitate natural airflow caused by wind, thermal differences and air pressure differences inside and outside the home. Windows, doors, vents, chimneys, and wind towers are examples of natural airflow solutions that can ventilate a home. While energy-efficient and cost-effective, natural ventilation options may be limited based on local climate and other factors.
  • Mechanical. A mechanical ventilation system uses mechanical implements to force ventilation and air circulation in the home. Mechanical ventilation solutions can include exhaust vents, furnaces, air conditioners, and window fans. Many homes utilize at least some type of mechanical ventilation, although these are less common in older homes.
  • Hybrid (mixed-mode). Hybrid ventilation uses a combination of natural and mechanical ventilation solutions. This is the most common ventilation system featured in residential homes. Even if a home is designed to ventilate solely through mechanical solutions, windows and other openings offer natural ventilation as an alternative.

Do Houses Need Air Vents?

Air vents are essential for any residential home. As mentioned above, proper ventilation of both interior living spaces and a home’s attic are critical to cycling in fresh, healthy air while eliminating indoor air that is high in pollutants.

Through ventilation and filtration of that air, you can eliminate mold spores, dust, allergens and other debris from the air, supporting your health and maintaining the structural integrity of your home. Both local health codes and local building codes likely require proper ventilation for any home construction project. A professional roofing company can offer more education on local venting regulations.

What Is the Best Type of Attic Ventilation?

When heat and moisture build up in your attic, it can lead to serious problems, including mold and other developments that damage and rot your roof from the inside out.

Proper attic ventilation can provide enough air flow to release heat and moisture, supporting your attic’s health. The best type of attic ventilation may depend on the type of roof structure you have, as well as the level of ventilation your attic needs. Some of the best options include:

  • Wind turbine. Whether natural or mechanical, a wind turbine can offer powerful attic ventilation that pushes out hot air while pulling in cooler air through the roof’s soffits.
  • Electrical exhaust vent. In cases where natural ventilation is not sufficient, many types of electrical exhaust vents can forcibly ventilate your home’s attic.
  • Ridge vent. Both ridge and hip vents are simple, natural air vent solutions added to the ridgeline of your roof’s peak. These are cost-effective venting options that have grown in popularity among modern home constructions.
  • Solar vent. As an alternative to hardwiring an exhaust vent to your home’s electrical infrastructure, solar vents can easily generate energy to power an exhaust vent on your roof.

What Is a Fresh Air Ventilation System?

Instead of recirculating filtered indoor air throughout your home, a fresh air ventilation system uses outdoor air intakes to replenish your indoor air supply with an outdoor air source. This source of “fresh air” can improve the quality of your indoor air, venting out carbon monoxide and other harmful air contaminants, while also making it easier for heat and moisture to be replaced by cooler air.

Many air vent systems are designed to release older indoor air while intaking fresh outdoor air as a replacement.

How Much Does a Whole House Attic Fan Cost?

While attic fans play an important role in maintaining a healthy roof and home, these venting solutions are very affordable.

The average cost to install an attic fan typically ranges between $300 and $550 nationally, although larger fans and/or advanced venting solutions like a solar vent may cost extra.

How Do You Fix Poor Ventilation In a House?

Your home’s ventilation needs may change for many different reasons. In some cases, old mechanical vent solutions may fall into disrepair and require replacement. In other cases, vents may have been improperly installed when the home was still built, resulting in potential moisture and heat issues for your attic or home.

Regardless of how poor ventilation issues develop, the only way to fix this is by adding ventilation to the parts of your home that need extra ventilation support. In an attic, for example, this may mean additional air vents installed into your home’s roof. In a kitchen or bathroom, poor ventilation can be fixed by adding or replacing the mechanical exhaust fan in that room.

If your home is dealing with issues connected to poor ventilation, a local roofing company can help assess your ventilation needs, recommend solutions, and provide a quote for installation services.
