Whole House Fan Systems & attic vent fans

For years, folks called whole house fans "attic fans" because they were installed in the attic and used to cool and move air through the entire home.


Watch this short video to see the difference between the two.

ventilation information below - it's important!!

Specifics About Attic Fans

Solar-powered attic fan

Attic Fans Regulate Attic Air & Temperature

Attic fan systems are specific to the attic space and work to evacuate heated air for the attic space. Eliminating damaging mold and regulating roof tempurature.

Attic Fans Regulate Air Temperature

These fans are equipped with either solar or a/c adapters and have a thermostat that allows the vent to come on at a set temperature, turning on to circulate and evacuate attic air during peak critical times where heat builds up.

Attic Fans Operate any Day all Year long

Powered attic fans operate anytime throughout the day and anytime throughout the year, summer or winter once the heat in the attic rises to meet the thermostat set point.

Attic Fans Prevent

  • Attic heat build-up year-round.
  • Ice dam build-up and roof root during the winter months.
  • Mold and mildew development and keep your home free of harmful pathogens. 
  • Professional installation with 5 yr limited warranty on all QC attic vent fans.

attic ventilation - it's important

Quiet cool central air conditioner plus attic fan

IT'S ALL ABOUT AIRFLOW

Protect Your Home and Health

WE PROVIDE AND PROFESSIONALLY INSTALL ALL OUR OWN ROOF VENTS!

One of the key benefits of the QuietCool System is evacuating the hot summer air out of your attic on a nightly basis.  Heated air in your attic an reach upwards of 120 degrees creating an "oven" above your living spaces below.  


Ventilation recommendations are based on the CFM of the QC system that is recommended for the SF of your home.  Having adequate ventilation ensures optimal efficiency and operation of your QC system and perfect cooling and indoor air quality for your home.


Adding all your net free air sf of your existing venting will determine if you need add'l venting or not.  If you need add'l venting our professional roofing partner can install ONLY what is needed for optimal performance.  


Types of venting we recommend: 

  • Static dome roof venting is  effective and efficient and our 1 sf net free air static dome vents are perfect for add'l venting. 
  • Solar powered attic vent fan w/ac adapter
  • Smart attic vent fan with programmable  app


 Some companies might recommend installing soffit venting.  Soffit vents are intake vents where roof vents are exhaust vents.  Soffit venting should include soffit baffle installation and will meet current code requirements.  If baffles are not installed at the time the soffit vent is installed you run the risk of insulation falling onto the vent blocking its airflow - you will simply end up with a blocked hole in your soffit with a grill.  Please make sure anyone recommending the installation of soffit vents includes baffles in their pricing.


In summer, the sun heats air in the attic. In winter, heat from your home warms attic air. Good venting occurs when air can enter the attic near the eaves and exit near the peak. Ideally, half of the vent area should be low and half high. The ultimate goal is keeping the temperature level in the attic space matching the outdoor temperature as close as possible.
