Why Is Ventilation Important?
July 17, 2017
Home ventilation is important to maintain comfort, health, and indoor air quality in the home. Without proper ventilation, air in the home becomes stagnant, contaminants exist at higher concentrations, and moisture levels can rise, leading to mold and other issues.
Why Is Home Ventilation Important?
Home ventilation is important to keep the house and its occupants healthy and comfortable. Ventilation is a key component to maintaining proper indoor air quality. Ventilation keeps air flowing through the home, eliminating contaminants, moisture buildup, and odors.
Home Ventilation Important for Moisture Control
Moisture can easily build up in a home, caused by natural air infiltration and activities that take place indoors such as showering, cooking, and appliances that use hot water. Without proper ventilation, this moisture builds up within living areas, seeping into walls and sticking to surfaces. This creates an ideal environment for mold growth – exposure to mold is dangerous for your family’s health, and mold growth can cause serious damage to a home.
Exposure to mold caused by poor ventilation can cause health issues such as:
- Irritation of the eyes, nose, and throat
- Immune system issues
- Worsening of symptoms in those with autoimmune diseases
- Respiratory damage
Proper ventilation eliminates moisture buildup in the home by keeping air moving. Excess moisture is moved out of living areas to prevent mold growth and damage to structures and furnishings caused by exposure to high moisture levels.
How to Properly Ventilate Your Home
Homes benefit from a combination of natural and mechanical ventilation. Opening windows and doors allows air to flow into and through a home. Even cracks surrounding windows and throughout the home benefit ventilation, though these areas are often sealed in the interest of energy efficiency.
Mechanical ventilation includes exhaust fans, whole home ventilation systems, and the air ducts of your home.
- Exhaust fans allow for targeted ventilation in areas where it is needed most. Run exhaust fans in the bathroom when taking a hot shower to eliminate moisture buildup, and in the kitchen while cooking to remove excess moisture and food odors.
- Whole home ventilation systems work within the air ducts of your home to keep air moving. Exhaust airflow systems extract stale indoor air, moving it outside the home. A supply system draws fresh air into the home. A balanced ventilation system combines the two to expel stagnant air and constantly replace it with fresh air.
Improve the ventilation of your home by ensuring all vents are open and unblocked. It’s not uncommon for a piece of furniture or a rug to be positioned over or in front of supply and return air registers leading to the home’s duct work. When these vents are blocked, conditioned air cannot enter living areas and stale air cannot exit them. Blocking registers diminishes indoor air quality and will make it more difficult for your HVAC system to properly heat or cool the home.
