"V" Stands for Ventilation: The Importance of a Good Ventilation System

HVAC stands for Heating, Ventilation and Air Conditioning. Unfortunately, Ventilation is suffering from “middle child syndrome.” The truth is that ventilation is just as important as its siblings.

Modern homes tend to be too airtight. This has positive and negative outcomes. People are concerned about rising energy costs, so it's important to live in a space that is properly sealed. Air leaks can feel like you're throwing money out the window. Tighter homes are considered more efficient homes, and from one point of view, they are.

However, from an air quality and ventilation standpoint, one has to consider that if air can't get out, nothing can. Contaminants and other air pollutants have no way to escape and are therefore recirculated throughout your home and into your lungs. Ventilation and Indoor Air Quality go hand in hand. There is a much higher risk for unhealthy levels of indoor air pollution today than ever before.

Ventilation systems ensure protection from common consequences of poor indoor air quality. Symptoms may include dizziness, headaches, allergies and even asthma. Recirculated indoor air must be exchanged with filtered outdoor air in order to maintain a healthy environment for your lungs.

The Importance of Ventilation

One important job of ventilation is to regulate moisture. Adequate airflow means that your walls and windows will not collect moisture and condensation. Moisture leads to mold, mildew and other contaminants. Long-term exposure to mold is extremely dangerous.

Proper ventilation also prevents air pollutants from having adverse health effects on your home's inhabitants. Homeowners, especially if you own a more modern or "tight" house with an HVAC unit, must be vigilant to protect against allergens, as they can cause respiratory damage, especially in someone who already has asthma or an autoimmune disease.

Many times, however, adequate ventilation isn’t enough. If you have moisture problems, speak with the professionals at Gold Medal Service about Waterproofing and Humidification services.

How do I know if I have a ventilation problem in my home?

  • Moisture buildup on windows and walls
  • Signs of excess infiltration, meaning drafts
  • Smelly or stuffy air
  • Lingering home odors
  • Respiratory symptoms

Ventilation systems are especially important in bathrooms and kitchen when moisture can create breeding grounds for microorganisms. If any of your ventilation fans are broken, we recommend getting them fixed as soon as possible.

Home Ventilation Benefits

  1. Reduces Condensation and Moisture Buildup - Moisture is always a top concern if a home is not properly ventilated. Moisture buildup and condensation are often the first visible signs of a major ventilation problem.
  2. Lowers concentrations of radon gas and carbon monoxide - Both poisonous gases are colorless and odorless and can build up without adequate ventilation. Healthy levels can be maintained when ventilation systems are working properly. Carbon monoxide is one of the main reasons why you want to ensure proper ventilation for your heating system. Learn more about the importance of furnace vent pipes.
  3. Improves indoor air quality - The quality of your indoor air is dependent on proper ventilation. Alongside proper ventilation, be sure to maintain the health of your HVAC unit by changing the air filter every 30-60 days and scheduling annual spring tune-ups.

  4. Decreases airborne toxins such as VOCs (volatile organic compounds) - From paint to pesticide, VOCs are emitted as gases from certain products. Without ventilation they are stored inside instead of dispelled out of the home. Health effects range from headaches and loss of coordination to fatigue and even cancer. This is why it’s important that you inspect your household cleaning products to ensure they aren’t emitting VOCs and other harmful contaminants into your indoor air. Air fresheners, which contain phthalates, and candles, which contain hydrocarbons, might smell nice, but they are likely adding poison to your environment. Read more about VOCs and their impact on our health and indoor air quality on the Environmental Protection Agency (EPA) website.
  5. Helps protect you from allergens, such as pollen, dusts and other irritants - Damp environments are breeding grounds for mold, dust mites, and other pollutants that can initiate or worsen asthma and other respiratory conditions.
  6. Improves respiratory health and reduces risk of aggravated asthma - Proper ventilation reduces the threat of allergens. Recirculated indoor air is replaced with filtered outdoor air allowing for a fresh environment. For family members already susceptible to lung issues, ventilation has a huge impact on quality of life.
  7. Ventilation systems allow you to ventilate properly without energy loss - Your home must have a balance of insulation and ventilation. If energy loss is a concern for you, proper ventilation should be too. In fact, ventilation solutions such as Attic Fans can help you save money on HVAC costs by venting hot and stuffy air from your attic.
