The ventilation system allows the HVAC system to heat and cool the home by sending air through the ductwork and vents. In fact, the “V” in HVAC stands for ventilation.
- Air purification
The ventilation system pushes purified air in so that stagnant air can be circulated out. This ensures every room feels comfortable day and night. Otherwise, you’ll be breathing in air pollutants, odors, and allergens.
To ensure the ventilation system continues to work properly, you’ll need to have the ductwork cleaned to remove dust, dirt, and other particles. Reach out to Blue Apple to learn more about ductwork cleaning.
- Maintain proper air pressure
The ventilation system also balances air pressure in the home, preventing doors from opening or closing on their own. Negative or positive air pressure is an imbalance that can cause strange drafts in a room.
- Maximize energy efficiency
The ventilation system circulates warm air during cooler months, and cool air during summer months. This helps reduce energy costs and extends the life of the HVAC system. When a system’s ventilation system is working properly, heating and cooling is highly efficient.
- Maintain moisture level
Moisture levels in bathrooms, kitchens, and laundry rooms can lead to problems with mold and mildew. A ventilation system will help balance humidity levels by blowing air into the room.
The Main Components of The Ventilation System
There are two main types of vents in the ventilation system: exhaust vents and intake vents.
Exhaust vents remove air from the home, while intake vents draw cool air in through the eaves and soffits.
The four types of exhaust vents include:
- Ridge vent. A louvered section of metal extrudes from and covers a gap at the top of the roof.
- Roof vent. Square, metal, and diminutive.
- Turbine vent. Contoured vanes pull heat from the attic.
- Gable vent. Louvered triangles or square vents fit at the end of the attic, near the roof’s peak.
The four types of intake vents are:
- Soffit vent. Metal louvered frames that go across the entire soffit area.
- Eave vent. Circular-shaped and used to improve attic ventilation.
- Rafter vent. Prevent attic insulation from blocking airflow from soffit and eave vents to the upper exhaust vents.
- Foundation vent. Louvered metal vents that allow air to circulate through a crawl space or basement and prevent excess humidity.
