Do Whole House Fans Use a lot Of Electricity

Just like any other piece of an appliance, the whole house fan does require electricity to run and operate. The level of power consumption, however, varies significantly from one appliance to another one. It is important that you prepare yourself appropriately in order not to be shocked. Such guidance on whole house fan electricity use is also necessary to prepare you appropriately for the expenses that ordinarily come about.

It will be like air conditioning your whole house minus the air conditioner. There are so many types of fans for your house – quiet cool fan, ceiling fan, tower fan, attic fan, pedestal fan, window fan, box fan, etc., to scatter the hot indoor air. In summer it feels even indoor air even hotter than outdoor air. You can also count on the exhaust fan and soffit vents, ridge vent, attic venting with attic vents. Although these setups do not have the advantages of your ac unit air flow, or central air conditioning and temperature cooling of heat and ventilation of ac unit, they will give you some comfort no doubt. But energy consumption or electricity usage will not be insignificant by any means.

We have prepared this guide to do just that. Our discussions hereunder shall seek to investigate those factors which determine the level of electrical energy consumption and energy cost by determining the wattage of the fans and the kwh. Thereafter, we shall look into the energy consumption patterns of some of the top models of whole house fans. If you can properly measure, you can actually do some energy savings and cut cost.

Do Whole House Fans Use A Lot Of Electricity

Brand or Make

The field of the manufacture of whole house fans is flooded with many players. These players produce unique products that similarly consume a varying amount of electrical energy. Before embarking on a purchase, it is vital that you ascertain how much power that equipment is bound to cost before doing so.

Prevailing Weather Conditions

A whole house fan generally comes in when the exterior temperatures are cooler than the interior ones. It hence goes that the nature of the external weather conditions has a great say in how the equipment may operate. This, in turn, determines the rate of power consumption of the gadget altogether.

Floor Space

Floor spaces vary significantly from room to room. The size of the floor obviously has a bearing on the consumption of power by the whole house fan. A larger floor definitely requires extra power to appropriately impact. Such a floor will demand that your fan consumes higher levels of electrical energy. The opposite applies to the smaller floors.

Duration of Use

The length of time that a whole house fan runs also determines the amount of electrical energy that the whole house fan consumes. Obviously, a fan that runs longer consumes more energy than that which runs for a shorter amount of time. It is hence necessary that you regulate your consumption and use it appropriately.

Power Rating

Lastly comes the power rating. This refers to the total electrical power needed to guarantee the normal operations of an electric appliance. It is expressed in Watts and Volts and differs markedly from one appliance to another. A highly rated appliance will consume more power and vice versa.


Having known those factors which determine the consumption of electrical energy, we now venture into the electricity requirements for different models of whole house fans. To do this, we have identified the best whole house fans as of 2020.

1. AIR VENT 54508 36″ Whole House Fan

To operate this machine, you will have to expend 120 Volts and 450/250 Watts of electrical energy.

2. QuietCool AFG SMT-3.0 Smart Gable Attic Fan

This is similarly rated 120V and 140-145 Watts. It also serves to extend the life of your room chiefly by preventing mold.

3. Vortex 711 CFM S-Line S-800 Fan

4.  Panasonic FV-30VQ3 WhisperCeiling 290 CFM Ceiling Mounted Ceiling Fan

This one bears the 120 volts and 60W rating. You will find it pretty awesome for those areas that are smaller and less cramped up.

5.  AirKing 9166 20″ Whole House Window Fan

The model has the ability to operate smoothly between 52-90 watts and 120-volts of electrical power. As such, it is a good choice to consider if yours is a smaller room that requires not a powerful fan.

6. Broan 35316 Gable Mount 120-Volt Powered Attic Ventilator

Lastly, this one bears the 120V and 24W ratings. You will find it suitable for those rooms which are smaller yet crucial like the living and dining rooms.


How we wish we could go on and on and on if it were possible. Due to the limitations of space and time, we inevitably had to stop there. Consider carrying on from where we have left. Most importantly, do keep a watchful eye on the power ratings of the equipment you are interested in.

That is the only way to be assured seamless operations and smooth services. As you look for a suitable whole house fan, factor the costs, the configuration of your room, and the floor spaces. These also have a say on what kind of appliance may be suited to your use.
