Attic fans are a type of HVAC exhaust fan that is installed on the top of a house to help with ventilation. Their purpose is to draw all hot air out, removing humidity and stagnant heat. These fans can be mounted on a wall or a roof and can be manually controlled or turned on by a thermostat. Units that are controlled by thermostats can turn on automatically when the attic has reached a set temperature.
How do HVAC Exhaust Fans Work?
Attic fans or HVAC exhaust fans direct hot air out through the main vent and use standard vents to bring fresh air back in. This allows fresh air to keep flowing throughout the space, significantly lowering humidity levels. When it comes to selecting an HVAC exhaust fan, there are multiple options to choose from. Some rely on ductwork, whereas others use their own air ducts. Whatever their way of generating airflow, they must always be properly vented, sealed, and insulated from the rest of the home. If it fails to be well insulated, the fan will begin to extract cool, air-conditioned air from the rest of the home, leading to problems in energy bill levels.
How to Install Attic Exhaust Fans
An Aire Serv professional can install your HVAC exhaust fan after auditing the number of vents that currently exist in the space. Since the area will need to be well ventilated, we advise that homeowners install one sq. ft. of ventilation for every 300 sq. ft. of space. The purpose of doing this is to guarantee that the attic is completely cut off and sealed from the rest of the house.
After the house has been checked out to be well ventilated, our Aire Serv service professionals will help you decide which option is in your best interest. We'll weigh the pros and cons of each variety and then get to work once you've made your decision. After installing a shutter or cover over the opening of your fan, we'll begin to install the unit itself, finishing up with wiring.
