Taking a Closer Look at Attic Ventilation

In a warm, sunny area like Orlando, daily incident sunlight shining on your roof causes heat transfer to the air inside your attic. When the air in your attic is warm, it increases the ambient temperature in your home, causing discomfort and increasing the load on your air conditioner. Attic ventilation is designed to allow warm air inside your attic to escape, thus reducing the temperature of the air in the upper portions of your home.

The Types of Attic Ventilation

There are several type of attic ventilation solutions; these systems may provide either passive or active ventilation to encourage airflow in your attic. Passive ventilation systems are nonelectrical systems that simply rely on the fact that hot air rises and cool air sinks; these vents allow air to escape at the top of your roof, drawing in fresh air from the bottom of your roof. Common examples of passive vents include ridge vents, gable vents, static vents, and wind turbines; each of these systems is paired with soffit vents, which are intake vents that pull cooler air in to replace warm air that is lost. By contrast, active or power-assisted vents require external power to move air; this power may come from your home’s electrical system, or from a small solar panel attached to the vent to eliminate any electrical costs to you. Just as with passive vents, active vents should be paired with soffit vents to replace air that is lost and keep your home’s pressure neutral.

The Benefits of Attic Ventilation

Regardless of the size or style of your home, attic ventilation plays a vital role in the quality of your indoor environment and the monthly costs of running your air conditioner. When hot air accumulates under your roof with no way to escape, it increases the temperature inside your home, leading to higher cooling bills to offset this temperature increase. Furthermore, poor attic ventilation can also impact the performance, reliability, and longevity of your air conditioning system by requiring it to work harder and longer to reach your desired temperature setpoint, raising the risk of wear and tear or damage that could cause a breakdown or result in the need for premature replacement. By allowing heated air to escape from your attic and pulling cooler air inside, attic ventilation can help to reduce your cooling bills; even if you don’t see a significant reduction in your monthly cooling costs, you will experience lower costs associated with your air conditioner because of this process. Because your air conditioner will be under less strain to cool your home, it will last longer and experience less wear and tear between AC maintenance visits, reducing both the cost of maintaining your AC and allowing you to keep the appliance for its full expected lifetime, rather than pay to replace it prematurely.

Even if your home’s design incorporates existing attic ventilation, it may not be adequate to deliver the best results.
