How Do I Get My Fan Installed?

Installation is straightforward and simple. Ideally if you are handy you can install the fans yourself and have them wired by a licensed electrician or simply plug them in.  Normally any handyman, electrician or contractor can install a whole house fan.

How Do QuietCool Fans Work?

Because heat rises, the rooms upstairs and especially your attic is generally much hotter than the rest of your home.  This hot air acts like a heating blanket that keeps your entire home hot, even into the cool evening hours.

QuietCool Fans remove the hot and stale air from your entire home and replaces it with cool outside air.  The fans Quietly pull the cool air into the home through several opened windows.  As the air circulates, the fans suck the air up into your attic.  This creates a positive pressure in the attic causing the hot air to be pushed out your attic through the existing attic vents.  This continuous circulation of air not only cools your attic, but also cools your entire living space.  You can actually feet a cool breeze of air.

The motors and flexible ducting for the QuietCool Fans are installed in your attic space so the only thing visible from inside your home is an attractive, white ceiling grille and a switch & timer on the wall.  We recommend installing smaller fans (like the QC-1500, QC ES-1250, QC ES-1700 or the QC-2250) in each of your occupied bedrooms and a larger QuietCool fan in the hallway.  Yes, you can sleep with the QuietCools running on warm summer nights.

Utility companies report that the installation of a whole house fan can cut some air conditioning bills in half!

The QC CL-3100 is one of the most popular QuietCool whole house fans on the market.  This powerful fan moves an impressive 3,190 CFM or air.  It is designed to cools up to 1,600 square feet of living space.

This is the right fan to install in a larger room or hallway in combination smaller individual bedroom fans (QC-1500 or QC-2250 if a multiple fan configuration is desired) to attain the correct air flow for your home and for zoned cooling and ventilation control.  To properly size your whole house fan you simply take your square footage and multiply it by 2-3 times. So a 2,000 sq foot home would need about 4,000-6,000 CFM.  This level or CFM can be achieved by using one large QC fan fan or multiple QC fans.  Just add the CFM output per fan until you get to the aforementioned CFM range.

Installation is very easy and wiring can be done by any electrician or it can be plugged into an attic outlet.  A handy template is included to install the ceiling grille.  A power cord is included with this and all of the Classic Line fans for easy plug-in installation.  The QC CL-3100 uses a built-in damper that prevents air from entering the attic or from the living area when the fan is off.

2 Speed Capable Motor - The QC CL-3100 can be modified to run at 2 speeds. This process requires the removal of the attached power cord and a third wire needs to be run to a 3-way wall switch for this optional feature.  If using a remote system, or standard on/off wall switch, the fan will operate normally, but just at the single, high speed.  Check with your electrician for further details.

If necessary, the damper box can optionally be mounted on a wall instead of a ceiling with the use of the optional 14" x 22" Vertical Wall Box Adapter, QC-60092.  The QC-3100 is maintenance free and comes with a 10 year warranty.

Yes On The QC-3100!

Yes On The QC-3100 I'm new to whole house fans and I was astonished by how well they work. The qc-3100 is powerful and quiet enough to install over your child's bed..... This fan is amazing! If you are undecided on the QuietCool, I suggest that you buy it, you will not regret it.
Very effective system.

I have installed 2 traditional belt drive whole house fans before in a friend's house. The first one had its motor gone bad within a year. The down side of the traditional whole house fan is that there is no insulation above the fan and the fan is very loud (like a helicopter lading on the roof, when the fan is at full speed). Of course, you can build a box around the fan and insulate it in the winter. However, I was looking for a product that is much quieter than the traditional whole house fan, easy to install and much lesser maintenance in terms of insulating it every winter. My house structure and requirements are as the following: 1. 1700 sq feet above grade (two floors) + 400 sq feet of finished basement. Most bedrooms are on the 2nd floor and 1 bedroom is in the basement. 90% of the square footage has ceiling height of 8 ft. The other 10% has a ceiling height of about 18 feet (cathedral ceiling). 2. I have blown-in insulation of R39 or more in the attic. 3. I only want to cool down the above grade (1st and 2nd floor) in the house. Fan Design: 1. Unlike traditional whole house fan, the grille that is attached to the ceiling has no louvers. From my opinion this is good design because I have seen traditional whole house fan where the louvered grille rattles and can be quite noisy when the fan is turned on. 2. There are two insulated flaps (I believe about R5 value) in the rectangular duct. When the fan is turned on, the flaps open up and stays open. It does not rattle. It's very difficult to see the flaps through the grille. Therefore, I think this design does NOT make your ceiling look ugly when you look up. 3. The 6 foot duct pipe/trunk is also insulated. 4. The fan has two speed settings. It comes attached with an electrical 3-prong cord. You can either put an electrical box in the attic and connect the cord to the electrical box or remove the cord and attach your own 14-3 Romex cable. If you use the cord, you only get
