Whole house fan and ventilation


We are the only company in Colorado to offer both QuietCool and Triangle traditional whole house fan systems. 

We are able to provide unbiased information about your fan and roof ventilation options and pride ourselves on creating the best cooling solutions for your unique home.

The Fan

The first step in creating the perfect whole house fan system for your home is to choose the correctly sized fan. Our recommendation is to install a fan that provides 3 CFM (cubic feet per minute) for every square foot above ground in your home. With this amount of airflow, the fan will achieve a complete air exchange in the home in approximately 3 minutes, and the whole house fan can serve as your primary home cooling system. 

We carry products from two of the nation's two leading fan manufacturers.  


Ventilation is a key component of fan effectiveness, which is why manufacturers require it for proper fan use.

A highly-efficient whole house fan system matches the ventilation in the attic to the airflow from the fan. Our fan manufacturers recommend a minimum of 1 square foot (144 sq. in.) of net free air (sfnf) ventilation for every 750 cfm of air moved by the fan. Most homes have about 2 sfnf in place, so additional venting is usually required to complete the installation of a whole house fan system. To complete your fan system, we install all-metal oversized (144 sq in of net free) roof vents. For homes with tile or metal roofs, we can install venting in the soffits or gables of your home.  

We have multiple types and brands of ventilation systems to best fit your home.

Save yourself the headache and make sure your system is installed correctly.  Independent contractors, handymen, and homeowners haven't installed thousands of systems like we have since 2003.  We stand by our work and provide a written one-year warranty at the time of installation.

Repair and service

While the fans we install carry a factory warranty for as long as 15 years, we can repair or service any whole house or attic fan.  Every existing fan we service undergoes a rigorous 15-point inspection and cleaning to extend the life of your system.  Trust the experts for a fast, thorough spring or summer service.

Extend the life of your roof

When summer temperatures soar to 160 degrees, the shingles bake from heat below. Too much moisture in the attic from stagnant air will result in mold that can damage the insulation and accelerate wear for the wood in your roof. Researching this topic will point to countless resources supporting this benefit.

Increase the lifespan of the fan motor

Have you ever plugged the exhaust of your car? Of course not. Pumping hot air into the attic without allowing it to escape essentially overworks the motor and reduces the lifespan of the fan. It may even void your manufacturer warranty.

Feel a better breeze

Allowing the air to escape the attic means more air can be pumped into the home. Faster air exchanges, faster cooling, and more energy savings.

Fan will run more quietly

Forcing air into a confined space often results in air being forced back into the fan, resulting in undesirable noise.

Reduce humidity in your attic and home

Evaporative coolers are great, unless all the water vapor collects in the attic. That's a surefire way to grow mold, bacteria, and other unwanted volatile organic compounds.

  • Our pricing includes all the framing, drywall, roof and electrical work required to complete the fan installation according to the fan, shutter, and vent manufacturers’ specifications.

  • For homes with high and vaulted ceilings, we recommend a fan that moves more than 3cfm/sf (as there is a greater volume of air in the home to be moved).

  • All of our whole house fans are installed with wall-mounted controls that include a timer and high/low switch.

  • Remote control options are available for all whole house fans – please inquire.

  • Oversize roof vents (each OS vent provides 1 sq foot of net free ventilation) and can be painted to match your roof color.

  • We have additional charges for installing vents on steep roofs (8:12 pitch and greater).

  • We can install Soffit Vents and Vertical Exhaust Shutters to provide ventilation for homes with metal or tile roofs.

  • We have additional charges for plaster walls, lead paint containment, high and sloped ceilings, and vertical installations.
