HVAC Pasadena: Common Attic Ventilation Myths & Misconceptions

HVAC Pasadena: Common Attic Ventilation Myths & Misconceptions

Effective attic ventilation is one of the most basic elements of energy-efficient homes. If your attic has insufficient exchange of stale and fresh air, your living space might get too hot or cold, depending on the season.

Poor attic ventilation can also lead to moisture buildup in your attic, damaging your home’s roof and walls, as well as insulation and personal belongings. Yet, solving this problem isn’t as easy as you think. Several attic ventilation myths are floating around, and here are just a few of them:

• More attic ventilation is always better. While you want a limited number of vents in your attic, don’t go overboard. With too many penetrations, your attic can become vulnerable to wind damage, sparks from wildfires, and intrusions from bugs and critters. A professional HVAC technician can inspect your home and make recommendations for the right level and type of attic ventilation needed.
• Roof vents make the most sense in warm climates. In truth, other strategies can improve energy efficiency more than attic vents in warmer climates. These include the right roof shingle color (lighter), controlling sun exposure and having sufficient insulation. Vents are more important in colder climates, where moisture intrusion from condensation is a greater risk.
• Warm air will escape through attic vents during the winter. While this may happen to a limited degree, it’s not a big factor you need to worry about if your attic is well insulated with proper air sealing. The benefits of effective attic ventilation, including moisture control, are likely greater than any issues caused by escaping warm air.
• You can learn about effective attic ventilation by researching the topic online. While you might find some answers, they likely won’t be customized to your particular home and climate. You’ll be in better shape if you avoid attic ventilation myths, and get professional advice from a trusted contractor or HVAC specialist.
