A whole-house fan is a type of home ventilation system. It pulls air from within the home and then vents it into the attic or the outside of the building. This creates a cycle of pressure that continually moves air into and out of the home, making it more comfortable for those inside.

How Does A Whole House Fan Work?

A whole house fan works by absorbing outside cool air through open doors and windows, during times that the temperatures are low – such as in the evening or the nighttime. The fan will simultaneously push warm indoor house air outside via your home vents, this way, creating a cool and natural indoor air environment. This way, the day after your fan began working, you will wake up and go back to sleep in a refreshing and comfortable home. It typically makes sense for your whole house fan to work when your home temperature is warmer than the outside temperature. You want to make sure that you have a window or a door open as well for the fan to work since it functions by absorbing cool air inside and pushing warm air outside.

How To Use A Whole House Fan

A whole house fan’s purpose is to cool your home. The first thing you have to do in order to use it and make sure that it is functioning properly is check that you have a sliding door or a window open so that the whole house fan can absorb outside cool air. Then, you want to make sure to switch the whole house fan on during the optimal hours – those being the cooler times of the day. Optimal hours would typically be during the nighttime – this is when outside temperatures are the lowers and last long hours.

Do Whole House Fans Work?

A whole house fan will work as long as the conditions for it are right. This would mean that the outside temperatures would have to, in fact, be cooler than the temperatures inside your home. For example, if the temperatures during the summer months are not cool enough even during the night time, then you are probably better off just using your air conditioning system instead to guarantee you cool temperatures. If summer night temperatures tend to drop where you live, however, then a whole house fan could be a great option for you and your family.

Benefits Of A Whole House Fan:

Owning a whole house fan comes with a number of benefits. Here are some benefits described below:

An Energy-Efficient Option

Whole-house fans are great for the environmentally conscious. The system is estimated to use up to 25 percent less energy than an air conditioner, making it a good option for warm summer days. You can reserve your air conditioner for when it’s blazing hot and save money for the rest of the time.

An Affordable Home-improvement Project

Installing a whole-house fan is easier and more affordable than you might think! It costs about half as much as it would to put in a new air conditioner.

Healthier Indoor Air

Air circulation prevents the air inside your home from becoming stagnant. According to the Occupational Safety and Health Administration, a lack of proper ventilation is one of the leading causes of poor indoor air quality.

A Quiet System

Air conditioners are often quite loud. The noise can interrupt music, entertainment, and conversation in the home. Your whole-house fan will run quietly, allowing you to enjoy a comfortable temperature and a quiet atmosphere at the same time.

A Speedy Way to Cool Down

Since whole-house fans don’t rely on a coolant to lower the temperature, you experience the cooling benefits right after you turn the system on.

Is A Whole House Fan Worth It?

Although a whole house fan may sound like it makes sense to use, is it actually worth it? The answer truly depends on the climate in which you live in.

To put things into perspective, in some geographical locations, during the summer months, it may be too hot for the whole house fan to work properly. On the other hand, during the winter months, you will not be needing the system at all. This being said, you are probably better off using your air conditioning in order to ensure cool temperatures and to avoid having the burden of owning a whole house fan during times that you will not need it. But what about in climates that work? An example would be geographical locations that provide cool summer nights. In such circumstances, we believe that a whole house fan is definitely worth it, and will be able to provide you with the cool fresh air that your home desires.


Some alternatives to whole-house fans include air conditioning systems or ductless mini-split systems. These are great options because they guarantee cool temperatures all-year-round, and allow you to adjust your indoor house temperature to the exact air levels that you desire. Although, a whole house air fan may be your better option.
