Attic Exhaust Fan Installation

It’s no secret that hot air rises—making your home’s attic one of the hottest spots in your house. In summer, attic spaces can reach over 160 degrees Fahrenheit! A hot attic can negatively impact your home’s overall temperature and increase the amount of energy you need to keep it cool.

Attic ventilation is just as important in the winter months when interior condensation is common, and exterior ice dams can form on roofs and eaves. Winter moisture trapped in the attic can cause mold and mildew to grow on insulation, leading to wood rot—making your attic unsafe for storage and people.

An attic fan can be beneficial to your home’s attic ventilation, keeping your home cooling in the summer and drier in the winter.

Read on to learn more about attic exhaust fans and attic exhaust fan installation from your local HVAC experts at Aire Serv®.

What is an Attic Vent Fan or HVAC Exhaust Fan?

Attic exhaust fan installation can provide better ventilation for a home. These fans are designed to draw hot air out, which helps regulate the stagnant heat and humidity present in most attics. Attic fans can be gable-mounted (mounted on a wall of the attic beneath a gable) or roof-mounted and can be turned on and off manually or controlled by a thermostat. Thermostat-connected attic fans turn on automatically when the attic reaches a specific set temperature.

A professional attic exhaust fan installation can do wonders to help mitigate mold growth, allergens, and other disease-causing microorganisms. Since germs and bugs love warm, moist air, attics can be an ideal habitat for them to flourish.. Venting warm air out of the attic can help draw up the cool air, whichhelps regulate your home’s temperature, especially living spaces. These fans also use less energy than your HVAC systems.

If you’re hoping to save money on cooling your home, adding attic ventilation fans is a smart idea. When used in conjunction with energy-efficient fans in your windows and ceilings, attic ventilation fans can cool down your space quickly and effectively.

How Does an Attic Fan Work?

Attic fans or HVAC exhaust fans work by directing hot air out of an attic through the fan vent and drawing fresh air in through standard attic vents. This process keeps fresh air moving throughout the attic, reducing the buildup of heat and humidity. In turn, attic fans assist in keeping homes cooler.

There are a few different types of attic exhaust fans available. Some HVAC exhaust fans can use the existing duct system to move air, while others use their own dedicated air ducts to ventilate.

For an attic exhaust fan to work effectively, it’s vital that an attic is adequately vented to the outside, insulated, and properly sealed from the rest of the home. If your attic is not well sealed, the exhaust fan will draw cool air (air-conditioned air) up through the attic and exhaust it out of the home, which is not what any homeowner wants. When you make an appointment for attic exhaust fan installation, make it a point to ask the professional to check your attic space to ensure it is well sealed.

Why is Attic Ventilation Important?

HVAC exhaust fan installation is a wise investment. There are a number of important benefits associated with proper attic ventilation, including:

  • Helps reduce extreme temperatures in attic space.

  • Helps reduce energy costs.

  • Helps extend the life of your home’s roof and insulation.

While your home can certainly function without an attic vent fan, installing one will definitely improve your home’s ventilation. This makes your attic less prone to mold, mildew, rot, and reduces its exposure to extreme temperatures.

If you suspect your attic ventilation needs improving, be on the lookout for the following signs:

  • An uptick in energy costs.

  • Increased frequency of HVAC repairs.

  • A noticeable buildup of ice along the edge of your roof.

  • Wavy roofline or shingles (frequently caused by warping of moisture-damaged decking).

  • An increase in allergy symptoms or respiratory issues.

In addition to the signs listed above, rust and corrosion on metal materials can also indicate ventilation issues, as can dampness and water stains on the attic side of your roof sheathing. If you’ve noticed any of these signs they could result from poor attic ventilation.
