We have come to believe that "the bitterness of poor workmanship lingers long after the sweetness of a low price has been forgotten."

The above pricing represents a "ball park" estimate of the cost of a whole house fan installation.
The size of the house is the square footage (sq ft) not including the basement. We do not count the basement when sizing for a whole house fan.
The amount of probable venting is based on the assumption that some ventilation has already been installed by the builder or roofer. This amount is usally found to be approximately 2 to 3 square feet of net area venting already installed. The above amounts are our guess as to how much more additional venting may be necessary to add for the fan to work effectively. Please see our ventilation page for more detailed information.
If you are interested in running an extremely quiet fan, consider having a larger fan installed that you would be likely to run at the low speed, yet it would move as much air a does the next smaller fan at the higher speed.
If you would like a more detailed estimate contact us directly via email or by phone: 303.695.7911
With our many years of experience we are often able to provide a very accurate price estimate over the phone or by return email.
Occasionally, some digital photographs sent to our email address, atticfan@gmail.com, will help illuminate an unusual or complicated situation.
For those situations when a personal visit is required, we are usually do so.
There is an extra charge for the following:
Plaster ceiling installation (usually houses build before 1950)
Vertical installation or Installation on a slope
Building a new attic entry
What to do after the estimate: In home final estimate/possible install
For customers who are satisfied with our on-line or phone estimate, we are able to send an installation crew to the home. Arriving in the morning, the installer does a technical walkthrough of the house, attic and existing ventilation and then reports to the homeowner. This usually takes less than 1/2 hour. The installer will describe what he has found and make his recommendations as to fan size and location as well as suggestions for additional ventilation, if any. Should the homeowner want to proceed with any or all the recommended work, the crew can usually complete the job that same day.
If the homeowner decided against doing any work, then the visit is simply a free estimate. Visits and installations beyond a 30 mile radius of our office carry a distance charge.
Out of state? Do it yourselfer?

For Out of State or DIY we would be please to provide all components plus a free phone consulation, if you have questions or need advice.
Our opinion about cheap fans from the big box stores
Saving money by buying a cheap fan will likely cost you more in the long run. While cheaper than the fans we sell, they represent the worst in fan engineering. We will not install them because the customer is rarely satisfied with their performance or their excessive noise level.
Beware of many of the newly designed fans sold over the internet. Most of them claim to run much quieter than traditional whole house fans. In fact they are comparing themselves to the cheap Big Box Store fans, not to a well engineered Weatherseal Fan system. The cost of these internet fans tends to be very high and the air movement very low. In addition, the unique engineering of these fans means that service and parts may well become an issue several years from now. Any breakdown of the fan might mean that it there are no parts available and it needs to be discarded and completely replaced.
A Weatherseal fan will last over 30 years and because it is made from commonly manufactured components, any parts that might fail can be easily replaced for many years to come.
