Frequently Asked Questions for Whole House Fan Systems
Q: How long does it take to complete an installation?
A: Most jobs are completed in approximately 4 hours. In certain circumstances, such as inclement weather, installation may take up to two days, although that is very uncommon.
Q: How can whole house fans be used as a substitute for air conditioning?
A: From working in this industry since the early 90's, I have heard the same account from hundreds of people prior to a fan installation. It usually goes something like this, "In the evening I walk outside and find it's cool and comfortable, but it's still incredibly hot in my home." In the evenings, the outside air in Denver is cool and comfortable 99% of the summer. Imagine replacing the hot, stagnant air trapped in your home and attic with this cool air from outside. Whole house fans are designed specifically to do this in areas like Denver where relative humidity is low and elevations are high. A/C is designed for areas with higher humidity. Whole house fans do the job of cooling your home and keeping it comfortable for around 10 times less electricity than running A/C, which means they cost 10 times less to run. A properly sized whole house fan system cools 10 times faster than A/C can.
A: A typical home has two square feet of total net free attic ventilation in place, but each home is different. Contact us and we will gladly give

A: We sell, install and service two different styles of Whole House Fans: traditional whole house fans by Triangle Engineering, and ducted whole house fans by QuietCool. Both of these whole house fans cool the home in the same manner by pulling cool air up through the home and pushing superheated air out of the attic. The difference is in the configuration of the fan. The traditional fan is located against the ceiling, while the QuietCool fan is suspended from the roof framing in the attic. Both Triangle and QuietCool fans are made in the USA. Triangle fans are constructed from heavy gauge steel with welded fittings. Cheaper store-bought fans use bolted fittings which loosen over time and create excess noise. Our Triangle fans are rubber mounted with sealed fan shaft bearings for a whisper-quiet operation. They have four,deep pitch blades. The fans also have a patented "Auto Belt Tensioning" system which eliminates the need for manual belt adjusting. They have a two-speed, belt-driven, 1/3
or 1/2 horsepower motor. These Triangle fans are the highest grade available on the market which move the most amount of air. QuietCool fans use superior motors and aluminum blades to create a fan that is very quiet, yet still moves a remarkable amount of air. Look at some job-site photos for examples, or see the table for technical details.
A: Whole house fans are located in the attic and use a damper system to keep air from moving from the home space to the attic when the fan is not in use. Traditional whole house fans use an aluminum ceiling shutter with moving louvers. These shutters are white to match ceilings, and their size is roughly 30" x 30", 36" x 36" or 42" x 42" (shutters are matched to the size of the whole house fan.) QuietCool fans are installed with a grille in the ceiling. The moving dampers for a QC fan are built into the fan assembly and are hidden from view. Like traditional whole house fans, the size of a QC grill is dependent on the size of the fan. In most whole house fan installations, aluminum roof vents are installed near the peak of the roof and on the back side of the house to allow superheated air to be exhausted from the attic space. The controls for whole house fans are installed in the wall of your home, and usually match your current switches. Please see our photo gallery for examples, and note that we have a showroom so that you can see, hear and feel our finished products in action. Contact us to schedule an appointment to visit our showroom.
Q: How quickly do whole house fans cool the home?
Q: What if I want to cool my attic space only?
A: In the case that you want to cool the attic space only, contact us and we can talk about installing a Power Vent/Attic Fan. See our page for Attic Fans.
Q: Why do many of our customers get fans installed after they have already invested in air conditioning?
A: Extremely hot air gets trapped in your attic during hot summer days. Through the late afternoon and evening, air conditioning has the chore of battling this heat that is radiating into the home. Because hot air within the home rises to the highest levels and cool air sinks to the lowest levels, air conditioning is fighting a losing battle. Customers relying on A/C alone find that they end up with an extremely hot upper level and extremely cold lower level with an A/C unit that is running continuously (at a $1 per hour!) and susceptible to freezing up. A whole house fan is designed specifically for areas like Denver with relatively low humidity and cooler evenings. A whole house fan is mounted in the attic, which draws fresh and cool outside air in through open doors and windows while forcing the hottest indoor / attic air out of the vents in the attic. This cycle quickly creates comfortable indoor environment, and most importantly, the fan steadily draws heat out of the structure itself so you start the next day with a cool house, delaying or eliminating the need to run air conditioning.
A: Though the terminology can be confusing, Attic Fans and Whole House Fans are very different from one-another. Attic Fans are smaller fans mounted on the roof or gable of your home. They work on a thermostat and help to flush out the hot air trapped in the attic but do not pull air through the living area of the home. These systems are ideal for homes that have existing cooling sytems which need help in cooling the home, or for homes that stay naturally cool with the exception of days where the temperature reaches 100+. Whole house fans are located in the ceiling of the home and pull air through the whole house (from the basement to the attic). These fans move anywhere from 3 to 7 times the amount of air as an attic fan, and have many other benefits as outlined in the See How The Fan Works section of this website.
Q: Is CHC insured?
A: Yes. We have a full liability insurance policy plus a workman's comp policy.
Q: Are the whole house fan motors guarded against overheating?
A: Each of our UL listed motors comes with a thermal interrupt, so that in the rare case that the motor might overheat it will automatically shut off. Also, the motors are constructed with sealed ball bearings. Because of this, the motors do not require regular oiling and are maintenance free.
