How Does A Whole House Fan Cool Your Colorado Home?

Indoor heat is always a major concern during summer. Simply opening our windows for passive cooling may not always be enough. We need to actively encourage air circulation and bring down the temperature. Fortunately, we have a lot of options to choose from including air conditioners, ceiling fans, attic fans, and whole-house fans. Each of these has its own strengths. In this article, we focus on whole house fan cooling to see how they work and how they benefit homeowners.

How Does a Whole House Fan Work?

First and foremost, the home fan should be installed by competent technicians. Ideal placement is in a central location such as the main hallway of the top floor. This will help it perform optimally as it tries to move air around the home. The other end terminates inside the attic. Whole house fans operate on the principle of Thermal Mass Cooling. They can provide excellent results for as long as the outdoor air temperature is lower than the indoor temperature. Here is how they work:

Pull Cool Air From The Outside

Open the windows to pull in fresh air from outside. The cool breeze should immediately reduce the indoor temperature. This also replaces the stale air in previously closed rooms. It is a good idea to do this early in the morning or at nighttime when outdoor temperatures have dropped significantly from their midday highs. Once the outside temperature starts to rise, you can close the windows and lower the air conditioner’s temperature. This way, the home can stay cool throughout the day.

Circulate The Cool Colorado Air Using The Whole House Fan

While the passive breeze is welcome, you may want the home to get much cooler. That’s why you need to switch on the whole house fan to pull in more air from the windows. The soft breeze will become stronger. Experiment with the width of the window openings. Find the sweet spot that enables just the right amount of active breeze.

Bring Cold Air Into The Attic

The whole house fan will pull air from the windows to the center of the top floor, cooling everything along the way. The cold air will then enter the short duct that terminates into the attic, which is usually the hottest part of the house. Bringing in a cold breeze into this section helps in reducing the heat that radiates down to the house, further improving comfort.

Push Hot Air Through The Vents

Without this system, the air in the attic will remain stale and hot. As the sun beats down on the roof, the space will only get hotter until it becomes unbearable. Thanks to the whole house fan, all spaces from the rooms below to the attic above will be colder. As cold air fills the attic, the hot air inside it is pushed outside through the vents. This airflow will continue while the fan is in motion.

The Benefits of a Whole House Fan In Fort Collins

Whole house fans are not meant to replace air conditioners or other cooling systems. However, they can be an excellent alternative under certain conditions. They can also provide compelling benefits that should pique the interest of many homeowners.

High Energy Efficiency

Air conditioners may be the preferred cooling solution for most households, but their high energy consumption leaves much to be desired. Whole house fans use much less electricity, so you can use them all day without worrying about consumption. You can also use a whole house fan early in the morning and late at night, when the outdoor temperatures are cool, reducing your dependence on your AC unit. This is a great way to reduce energy consumption and improve efficiency.

Low Cooling Cost

An efficient system like whole-house fans can deliver the desired cooling effect at a lower cost. Making the switch can free up a significant chunk of the monthly budget thanks to the drop in utility bills.

Better Indoor Air Quality

Improved indoor air circulation helps in removing odors from cooking meals and cleaning rooms. This also gets rid of cigarette smoke and foul smell from house pets. Fresh air will permeate the house so it is easier to breathe in. It also prevents the trapping of indoor air particulates, common when homes are closed up during the summer.

Greater Home Comfort

A whole house fan can help bring down the indoor temperature during summer and make it bearable to stay in the house throughout the day. It can be a lifesaver for those who need to work at home because it helps them focus on their job. The fan also makes it more comfortable to sleep at night.

Fast Indoor Cooling

Whole-house fans may have a simple configuration but they work. In fact, they can provide fast indoor cooling with people inside the house feeling a significant difference after just a few minutes of operation. You don’t have to wait for long to get relief.

No Toxic Refrigerants

Aside from using up less electricity than air conditioning units, these fans don’t use any ecologically harmful refrigerants. You can welcome these into your home without guilt. Keep them running as much as you need them to.

Quiet Operation

Air conditioners tend to produce noise while in operation. This can come from the air handler, the blower motor, the compressor, or the ductwork. It can get worse as the system ages. Meanwhile, whole house fans provide quiet operation. They’ll work in the background and you won’t even notice it.

Impressive Longevity

These fans can last for many years, making them a great investment. Just keep the system clean to enjoy impressive longevity and reliability. Technicians can help you through professional installation and annual maintenance.


If you are looking for an alternative cooling system, then consider getting a whole house fan. It can keep you cool in the summer without costing a fortune. Just be sure to contact expert installers for optimum performance and longevity.
