Whole House Fan Blog

Installing a whole house fan can be an excellent way to improve indoor air circulation while creating a cool, comfortable living space. Whole house fans can reduce the negative impacts of air conditioners on the environment, and reduce cooling costs while making your home more energy efficient.

Garage ventilation is essential, especially during the sweltering summer months. A poorly ventilated garage can trap warm stale air and toxic fumes, posing a health risk to your family while making your home environment uncomfortable.

Why is garage ventilation important?
Five reasons why garage ventilation is important are as follows.

Installing an attic fan in your house can improve your indoor temperature while maintaining energy efficiency by offering respite from the air conditioner.

Why install attic fans in your home?

Attic fans offer mechanical ventilation to your attic improving your life quality in various ways.

While installing a whole house fan can offer several benefits, it is especially important in the new home constructions in California. According to California Title 24, the new homes in climate zones 8 to 14 must install a whole house fan to reduce energy consumption while improving the indoor air quality.

Climate zones 8 to 14 are located in the western U.S., especially in California where Zone 8 includes most of the Central Valley and Zone 14 encompasses the inland areas of the Central and North California with some coastal areas. The zones are commonly referenced by following the “Sunset Western Garden Climate Zones”.

Does your home still feel hot even though your AC is working overtime? The problem might be your attic. In summer, attic temperatures can skyrocket to 150°F — and you need proper ventilation to prevent this trapped heat from seeping into your home and hindering your cooling efforts

The well-sealed modern homes often lack proper ventilation which is imperative in maintaining indoor air quality and promoting a healthy lifestyle.

What creates a well-sealed home?
A well-sealed home has a building envelope that minimizes air leakage while improving energy efficiency. Building envelopes are physical barriers in the form of walls, chimneys, roofs, and vents that separate the indoors from the outdoors. A well-sealed house is maintained by minimizing the unintended cracks and gaps in the building envelope.

A whole house fan is an energy-efficient alternative to an air-conditioner offering a fantastic way to cool your home.  Modern whole house fans, particular Quiet Cool whole house fans, are designed to be quieter than their older model predecessors.

How does a whole house fan work?

A whole house fan is typically installed in the central hallway ceiling. They work by drawing in the fresh outdoor air through the windows while the warm indoor air is pushed out through the exhaust and the vents in the roof.

What is off-gassing?
Off-gassing occurs when toxic chemicals, gases, and VOCs are released into the air. Your home can get exposed to toxic chemicals like volatile organic compounds (VOCs) that are released from home renovations, installing furniture, and purchasing new home items.

How does off-gassing happen in the home?
Off-gassing can be a concern in homes that are built with building materials that improve their insulation levels. While an insulated home can be excellent for energy efficiency it can cause a build-up of toxic chemicals, VOC, and trapped gas exposing the home residents to off-gassing.

A whole house fan can improve your home's ventilation throughout the year by removing indoor stale air while allowing the circulation of clean fresh air inside the house.

Why do you need whole house fans in the winter?

Although whole house fans are considered summer appliances, there are still some benefits you can enjoy from them during the winter months

If you live in a region that experiences harsh winters, you may have to deal with attic rain. Attic rain occurs when the outside temperature fluctuations and airflow issues cause moisture to accumulate underneath your home roof.

The trapped moisture may seep into your home causing water damage while affecting your home value.
