If you’ve ever gone up to the attic in your New Orleans, Louisiana, home during the summer, you know what hot and stuffy feels like. Most people don’t realize that heat and humidity don’t just affect the attic; they also place an added burden on your HVAC system. Fortunately, proper ventilation can help relieve that burden while saving money on your utilities.
Why It’s Necessary
Attics are designed to have adequate ventilation, but the better the ventilation, the less strain you put on your HVAC system. It’s no surprise that the heat and humidity in Louisiana collect in your attic. This added heat warms your ductwork, which in turn warms the air pulsing through your home. If your attic is ventilated properly, then your ductwork remains cool, and your HVAC system doesn’t have to work as hard to cool your home.
Types of Ventilation
The most common type of attic ventilation is an attic fan. Attic fans bring in cool air from outside while pulling the hot air outside. It might surprise you to learn that sealing and insulation are also components of attic ventilation. Proper insulation and sealing keep your air conditioner from wasting energy cooling your attic. They also keep unwanted air outside without bringing in extra heat and humidity during the hot summer months.
Similar Options: Whole-House Fans
Attic fans and whole-house fans are actually two different things. A whole-house fan works to keep the entire house cool instead of just ventilating the attic. A whole-house fan also keeps the home cool at night by bringing in the outside air when the temperature lowers. Attic ventilation is still necessary to allow the hot air to escape rather than collect in your attic, which would add strain to your HVAC system.
