How Whole House Fans Work

The idea behind a fan is simple. The fan pulls air in through open windows (or doors) and pushes it out windows or vents in the home’s attic or roof. This exchange in the air is rapid, and the warmer air from the house is quickly replaced by cooler air from outside.

Whole house fans are not the same as attic fans. Attic fans are installed in the attic and keep the attic space cooler, slowly drawing heat up from the home. Whole house fans are installed in the ceiling and actually change the air in the home.

Why Invest in Whole House Fans

Whole house fans have quite a few benefits that should be considered. While they may not be the end-all, be-all, and completely replace your central air conditioner, they can drastically reduce your reliance on them. Other benefits include:

  • Complete air exchange in the home about every 5 minutes
  • Can increase the home’s resale value
  • Cost-effective alternative to AC
  • Most effective cooling option during the late evening or early morning cooler temperatures

Choosing a Quality Whole House Fan System

Fan Type

There are three basic types of whole house fans. While we have an entire section dedicated to this comparison below the reviews, it is important to know that these three types exist.

Standard fans are the cheapest to install but may cause the most additional work (moving joists, adding ventilation, etc.) compared to the others. Insulated door fans are the most energy efficient and don’t leave your home open to the outside air during the winter. They are, though, the most expensive type.

Finally, inline or ducted fans (see below) are about average in cost, but you must have one installed for each room you want to cool. They are used with damper switches, though, and can give each room a nice breeze.


Ducted fans work with smaller vents in each room they are installed in. The insulated ducting connects the vents to the fan. The result is individual room control that offers a nice breeze when open and operating.

They do have dampers, which means you can isolate or include individual rooms in the cooling process, but windows and doors must be open to accommodate. These fans have more precise control but move far less air than non-ducted options.


For non-ducted fans, there are two basic types: belt drive and direct drive. The differences are slight but important. Belt driven fans have more moving parts and tend to be more challenging to install. They are quieter during operation, though but do have a higher maintenance regimen.

Direct drive fans are DIY friendly and use fewer bearings to operate (less moving parts). However, they tend to be louder to run and may not move as much air while on.

Coverage Area & Fan Size

The right size and capacity of the fan will depend on a lot of factors. This will include things like the size of your home, of course, and how many windows you have, how much they open, and even how many exhaust vents are installed.

To get an exact sizing for your specific home, you should get estimates and quotes from an HVAC professional. They will be able to take all the measurements and recommend the right size and type of fan for your needs.

Attic Vent Capacity

The attic vent capacity may be too small for whole house fans. In this case, you will need to install more vents. While this typically isn’t an expensive process, it can be time-consuming. The cost per vent adds up if there are a lot to install.

Efficiency Features

You can further increase the efficiency of the fans by choosing models with specific features. ECM motors, for example, work longer and have less friction making them suitable for long-term operation. They also cost less compared to standard fan motors to run.

Insulated doors are an option on some fan types. These close off the fans when the fan is not being used. This allows the cooler air to stay in the home, or the opposite in the winter. Without insulated doors, your fan becomes an open window during storms, snow, and cold snaps.

Installation/Mounting Type

Most whole house fans are considered DIY projects. Of course, the type and size of the fans you choose will play a role in that. Some fans, generally belt-driven, have larger frames and may need attic joists cut or adjusted.

Cutting joists and building fan boxes may require a trained professional. Even with the DIY options and clear instructions, you need a basic understanding of ceiling and attic space requirements, airflow patterns, and electricity.

Other Considerations

Other considerations are worthy of thinking about. Not all fans will come with these features, and most will raise the overall price. However, in almost all cases, the additional few dollars is worth it.

Remote Controls

Remote control operation is a simple way to control your fan without having to use physical controls. While there are better options out there (see below), remote controls can adjust speed, turn the units on or off, or even close insulated doors.

Wall Switches

Wall switches make controlling your fan’s operation easy. They work like any other control panel or light switch on your wall, and a flick of the switch or press of a button can have your home cooling in a matter of minutes.

Wi-Fi Connectivity

Wi-Fi connectivity is a new addition to these fans. Using your home wireless network, you can connect your fan controls to a mobile app or, in some cases, voice commands through Amazon Alexa devices. This allows you to control your cooling from anywhere.

Noise levels

While not a feature, noise levels are worth thinking about. Some of these fans can get quite noisy during operation. Type and install location will go a long way to reducing or creating the noise, and each model is different.


The warranty is crucial to have and to understand. You need to know what is covered and for how long. Moreover, though, you need to know what to do to make a claim and what should be done before needing one.

Some warranties need you only to provide proof of purchase, and some require professional installation or registration of the purchase within a specific time frame. Each warranty will be different, so make sure you know what you are getting into before you buy.

9 Best Whole House Fans Reviewed

1. QuietCool QC CL-4700

Best Whole House Fan
CFM/Airflow Rating4505 CFM
Coverage Area2200 Sq ft
Speed Settings3-speed fan
Mounting TypeWall mount
Voltage120 volts
Wattage591 watts

The best whole house fan goes to QuietCool. This fan set up is simple to install, has enough airflow to make an immediate, noticeable difference, and offers noise reduction ducting. Everything you need to enjoy fresh, cool air (except the hole in your ceiling) is included.

The classic line from QuietCool features an inline ducting that helps control airflow and dampens noise. The small duct attaches to the fan so you can direct the output to a specific area, vent or window. It also features hanging straps to use on bracers or joists.

Once hung, the straps and ducting act as a sort of noise dampening that keeps your attic space from echoing the noises of the fan. With a much quieter operation, you won’t constantly be talking louder or increasing your TV volume.

The system also includes gravity dampers that are controlled by barometric pressure. Since warm air weighs more, the dampers only open when the fan is on, and hot air is being pulled through. This also prevents cold air from escaping or warm air creeping in from the attic.

The split capacitor motors are energy efficient, too. You can save more money here with a motor that draws only what it needs to run, stores excess power, and uses the bare minimum from the storage capacitors.

With 4505 CFM airflow, you can replace the air about 4 or 5 times an hour in a home up to 2200 square feet. For larger homes, a second fan is recommended. With a 10-year warranty, you will be covered for a long time, should anything go wrong. The only thing you will lose, though, is waking up to hot air in your house.


  • 10-year warranty
  • Control panel switch can mount up to 100 feet away
  • 50 – 90% savings over AC
  • Simple DIY install
  • Barometric controlled dampers


  • Exhaust must be directed through ducting
  • Mounting straps may not be long enough

2. Centric Air QA-Deluxe 5500(R2T)

Best Whole House Fan For 2 Story Homes
CFM/Airflow Rating3945 CFM
Coverage Area2400 Sq ft
Speed Settings2 speed fan
Mounting TypeWall mount
Voltage120 volts
Wattage630 watts

Centric Air offers you the QA-Deluxe, a standard mount fan with ducting and positioning, much like our top pick. The fan install should only take a couple of hours and can be done by anyone with basic tool knowledge.

This model offers you two speeds (low and high) and can accommodate two-story homes up to 3400 square feet. It is still advised that anything over 2400 square feet uses a second fan. The cost benefits here are up to about 75% compared to an air conditioning unit, and you will notice the temperature difference right away.

The best part here is that your control panel offers you the ability to set the temperature. Of course, the fan doesn’t lower the temp beyond the air temperature outside; you can control the interior climate somewhat by having the fan shut off at a certain range.

You get a sturdy frame with this model, but the fan uses the single capacitor system of a standard fan motor. While it is still energy efficient, it isn’t as quiet or energy-conscious as a split resistor motor.

Another model (the 5500-W) is quite similar, though it is a little cheaper. It has a slightly smaller fan motor, and the control panel offers a power switch and timer. Beyond these three differences, though, the models are near identical.


  • 3/10-year warranty (parts/fan)
  • Simple DIY install
  • Everything included with purchase
  • Low attic vent volume needed


  • Single capacitor fan motor
  • Most expensive model on the list

3. TPI BD302WHS Belt Drive

Best Belt Drive Whole House Fan
CFM/Airflow Rating5800-7600 CFM
Coverage Area2100 Sq ft
Speed Settings2 speeds
Mounting TypeCeiling mount
Voltage120 volts
Wattage828 watts

The TPI belt drive fan is a monster of a whole house fan and will exchange the air in your home about every 4 minutes. It doesn’t offer a lot of extras, which is to be expected. Instead, you get a great motor and a solid fan for a great price.

This model ships fully assembled, so all you need to do is take it out of the box and put it in place. If you don’t already have a ceiling hole for the fan, of course, you will need to make one. Installation is relatively simple, though, and should take a novice handyman about 2 or 3 hours to complete.

The fan blades are treated and coated so they won’t corrode or rust. The motor and frame, though, are not. The belt is easily replaced when needed, though that won’t be for several years, provided you keep up on maintenance and protection.

The downside to this model is that there is a control panel switch used for operation and control of the motor, but it isn’t included. As a separate purchase, it is relatively cheap, but it would be much better to include it in with the fan.


  • 10-year warranty
  • Treated fan blades
  • Automatic shutters
  • Rapid air exchange


  • Control panel not included
  • Professional installation may be needed

4. QuietCool QC ES-3100

Best Quiet Whole House Fan
CFM/Airflow Rating3068 CFM
Coverage Area1500 Sq ft
Speed Settings3 speeds
Mounting TypeWall mount
Voltage120 volts
Wattage264 watts

QuietCool also offers the Energy Saver series. Much like our top pick, this hanging fan system dampens sound, offers high energy savings, and is simple to install. This model has a few different features and is designed for smaller homes.

With the Energy Saver (ES) models, the biggest difference is the fan motor. Instead of the dual capacitor system, this one comes with a brushless AC/DC motor. It is much quieter than other types and offers less vibration. The motors are also electronically commutated, meaning the direct current is converted internally.

Because the motors are more energy efficient, they are quieter and run smoother. However, they are also slightly less powerful. Ideal for smaller homes, this model can move over 3000 CFM airflow and is perfect for single-level dwellings up to 1500 square feet.

The hanging straps hold the unit in place with the included ducting and dampers being the same type as the top pick version. The dampers are also barometrically controlled and don’t allow warm air to creep in from the attic or cold air to escape when closed.

With the full 10-year warranty, you won’t need to worry about much. However, proper care and maintenance are needed with at least twice-annual cleanings of the blades and housing. Overall, though, the maintenance is low, and you can rest comfortably in a much cooler home.


  • 10-year warranty
  • Dampers included
  • Simple DIY install
  • No heat loss through vents


  • RF Control kit not included
  • Not suitable for larger homes

5. Cool Attic CX24DDWT Direct Drive

Best Direct Drive Whole House Fan
CFM/Airflow Rating4600 CFM
Coverage Area1800 Sq ft
Speed Settings2 speeds
Mounting TypeCeiling mount
Voltage120 volts
Wattage483 watts

If you are more interested in the direct drive fans, then Cool Attic has your answer. This fan moves a lot of air and offers very low maintenance. Designed, built, and assembled in Texas, you get a great fan already on a wooden frame with aluminum supports.

Claiming the best direct drive whole house fan isn’t easy, and Cool Attic makes that claim and backs it up. This rugged, highly durable fan comes with everything you need, including the control panel.

The two speed fan will exchange the air in up to 1800 square feet 5 to 6 times per hour. With full control over the speed and timing, you don’t have to worry about leaving the fan on overnight (as long as your windows are open) or running out of cool air.

The fan and motor come mounted in an aluminum frame with a wooden bracer. Installation doesn’t take long, especially if you are replacing an older fan. New installs can take up to 3 hours but aren’t overly complicated.

You also get a louver frame to help keep out rain, snow, or debris when you aren’t using the fan. The louvers are coated and treated to withstand the elements and come in a paintable white color. Leave them as they are or paint to match your trim.

Like most whole house fans, you also get a 10-year warranty on the fan and motor. The Texas-based company is easy to get a hold of and does everything in its power to make any issues or complaints right and keep their customers happy.


  • 10-year warranty
  • Great customer service
  • DIY install capable
  • Control switch included


  • Can be loud during operation
  • High speed may be too much for homes smaller than 1000 sq ft.

6. Air King 9166F

Best Whole House Window Fan
CFM/Airflow Rating3560 CFM
Coverage Area2200 Sq ft
Speed Settings3 speeds
Mounting TypeWindow mount
Voltage120 volts
Wattage170 watts (high speed)

If you don’t want to bother with cutting holes in your ceiling or you don’t have the attic space for a ceiling mount fan, the Air King 9166F is an ideal solution. This is the best whole house window fan that installs in seconds and doesn’t need anything extra.

With this fan, you get three speeds that can exchange the air in your home about every 30 minutes. Ideal for small to medium-sized homes, the 3-speed fan is also reversible. You can set the fan to pull air in from outside, or push air out from inside.

Your comfort is only a dial turn away. It really does install in seconds. Once you open the box, the fan sits in any standard window, with extension wings to cover open areas. The window then closes on the top of the fan to hold it in place. You can use screws to give it a more permanent mounting if you prefer.

Once it is in place, you just need to plug it into any standard outlet and turn it on. The dial is clearly labeled for intake or exhaust in all three speeds. Just make your speed and direction selection, and the fan starts running.

The one downside to this model is the warranty. You only get 12 months of coverage, and customer service can be difficult to get a hold of. Once the policy expires, there will be no help from the company. Luckily, if anything does happen after a year, these models aren’t costly.


  • Quick, painless install
  • Turn dial speed/direction selection
  • Steel protection grate


  • 1-year warranty
  • Won’t fit windows smaller than 27-inches

7. Tamarack Technologies HV1000 R50

Best Insulated Door Type Whole House Fan
CFM/Airflow Rating1000 CFM
Coverage Area2200 Sq ft
Speed SettingsSingle speed
Mounting TypeCeiling mount
Voltage120 volts
Wattage70 watts (total, 35×2)

When you are ready to step up your game and start saving a lot of money, the HV1000 from Tamarack Technologies has the fan for you. This insulated door type whole house fan works with dual fans and a single switch to move up to 1000 CFM through your 2200 square foot home.

This model does require professional installation unless you know how to wire a 120-volt circuit. Once installed, though, you can opt for the RF remote control or a wall plate control panel (both separate purchases).

When you want to use the fan, and after you ensure the windows are open, you turn it on and let it work. The automatic doors are insulated with R50 insulation, which prevents any cold or heat exchange when the doors are shut.

Once open, the two fans will turn on and start moving your air. The best part is that each fan operates with a max 35 watts, for a total 70 watt whole home fan. Even running 18 hours a day, you are still only spending about 40 cents to operate the fan.

The 3-year warranty is a little disappointing, but it does cover everything from the parts and labor to the doors, mechanisms, and fan motors.


  • Automatic doors prevent drafts
  • Simple operation
  • Single speed fans remove the guesswork
  • Massive energy savings


  • 3-year warranty
  • Professional install highly recommended

8. Hurricane GL56736590

Best Inline Fan For The Whole House
CFM/Airflow Rating1060 CFM
Coverage Area1800 Sq ft
Speed SettingsSingle speed
Mounting TypeInline mount
Voltage120 volts
Wattage300 watts

When you are limited on space and want to move a lot of air, look no further than Hurricane. This inline fan pulls a lot of air and, when properly installed, can make a world of difference in the temperature of your home and the money in your wallet.

The fans come in various diameters, from 4 to 12 inches. With a CFM rating of 1060, it can replace the air in your entire home about once every 20 minutes. However, the inline installation allows you to place a fan in only the rooms you need and control which ones are operating.

Unfortunately, the control remote isn’t included with your purchase, and neither is any ducting. However, the steel frame does have mounting brackets. Clear instructions are also provided for a DIY install that only takes about an hour.

Once everything is installed and operational, you can feel an immediate difference. There won’t be any issues as long as you have plenty of attic vent space (about 5 cubic feet per fan).

You also get a 5-year warranty that covers the housing, fan, and motor. For the cost, you can outfit your entire home with a few fans, and they will still pay for themselves in your energy bill within the first year.


  • 5-year warranty
  • Highly energy efficient
  • Mounting brackets included
  • DIY install


  • Doesn’t include ducting or remote control
  • Choosing the right size for existing ducting may be difficult.

9. AC Infinity CLOUDRAY T10

Best Energy Efficient Whole House Fan
CFM/Airflow Rating1201 CFM
Coverage Area2000 Sq ft
Speed Settings10 speeds
Mounting TypeCeiling mount
Voltage120 volts
Wattage136 watts

The Cloudray T10 from AC Infinity may sound like something from Star Trek, but what you actually get is the best energy efficient whole house fan on the market. The EC motor and dual door dampers give you incredible efficiency.

The best thing about the T10 is that this kit includes absolutely everything you need for install and operation. Not only do you get the fan and housing, but you also get the dual door dampers, fan grate, mounting clips, straps, power cords, ducting, and programmable control panel.

DIY installation can be done, but a professional may be needed for the control panel’s wiring. Once installed, though, you have a system with complete control. Not only can you select from the 10 speeds of operation ( 28 to 47dB noise rating), but the system will also monitor temperature and humidity.

You can program the fans to come on or go off based on either temp or humidity, or both. The bright LED panel displays the temperature, fan speed, and any alarms that are present. Mode selection, locked panel, and humidity percentages are also displayed.

The downside here is that the instructions are near impossible to follow, and some of the steps are mislabeled. Make sure you run through them a few times before making any cuts or drilling holes in your joists.


  • Sleek design and professional look
  • Digital display is easy to read
  • Sensor probes are wired
  • Kit includes everything needed for install


  • 2-year warranty
  • Install instructions are difficult to follow

Types of Whole House Fans Explained

Standard Fan

The standard fan is a large, louvered fan that installs in the ceiling of your home. It has the job of pulling the air from your house into the attic, where it is exhausted through the attic vents. These fans are generally considered open, as they don’t have covers or doors.

Best used in the early morning when temperatures outside are lower, you can move a lot of air. Typically these fans will range between 4500 and 7000 CFM, giving your home new air every 5 to 7 minutes.

They are also the cheapest of the three styles, with an average estimated install cost of about $200 to $500 each. However, you will need to purchase covers for the fans to use during colder months and when not in use for long periods to prevent heat from escaping through the open fan area.

Insulated Door Fan

Insulated door fans are like standard fans, except there is no need to purchase fan covers. The doors open and close (usually with remote or Wi-Fi connectivity) and will protect the fan as well as prevent air loss.

Best used in areas prone to cold weather or summer time cold snaps, these fans don’t move as much air as a standard fan. On average, you can expect about 1000 to 2000 CFM, which equates to complete air exchange in your home every 15 to 20 minutes.

They are also the most expensive of the three, with install costs ranging between $500 and $800 each. These fans are the quietest of the bunch, so you can use them overnight or during your TV binge session without being distracted.

Inline Fan

Finally, the inline fans are a per-room type of fan. They are the smallest of the three and feature individual ducting from the intake vent to the fan. They, too, are relatively quiet and offer dampers allowing you to control which rooms have the fans and which don’t.

They don’t move as much air as the other options, mainly due to their smaller size. You can expect between 800 and 1500 CFM or a complete air exchange in your home about twice per hour.

Installation takes longer with this type but is generally considered easier. You also don’t need covers for the fan as the dampers work to prevent air escaping.

Whole House Fans vs. Air Conditioners

Compared to air conditioners, whole house fans have their pros and cons. The cost of installation is among the chief pros for the fans, but there is a lot to consider.

When it comes to installation costs, central air conditioners will cost a lot more. However, the initial cost isn’t the only concern. Whole house fans typically cost about 90% less to operate. They use far less energy compared to an air conditioner and have much less wattage draw.

Unfortunately, whole house fans aren’t always the best answer. For example, they cannot cool the home lower than the outside temperature like an AC does. They also don’t filter the incoming air through your open windows.

This means they pull in any dust, pollen, or other allergens along with the air. Central ACs have intake filters to reduce these allergens and pollutants. Plus, unlike ACs, whole house fans aren’t allowed in every region.

The other significant difference is your windows. When the AC is on, it is typically warranted to have all doors and windows closed to maintain the lower temperature. With the fans, your windows must be opened. If the fans run while the windows are closed, it can cause gas line and pilot light back drafts and other dangerous situations.

Determining Whole House Fan Size

Sizing your whole house fan has a few determining factors. A professional HVAC technician can take all the proper measurements and give you an exact number for your fan’s size. However, you also have to balance in airflow and installation.

For example, a larger fan may end up costing more to install because you may need additional venting, joist cut-outs, bracing, or other features to install properly. In these cases, two or more smaller fans may cost less to install.

The guidelines for sizing are based on the square foot size of your home and your ceiling height. Based on an 8-foot ceiling, the expected size fan is 2 – 4CFM per square foot. Basically, you just take the square footage of your home and multiply by 2 or 4. This will give you the CFM range for the fan size needed.

For example, a 1500 square foot home with 8-foot ceilings will require a fan size of 3000 to 6000 CFM.

Whole House Fan Installation

Whole house fan installation is typically done by an HVAC professional. It is the recommended installation method because of the work that needs to be done. While some models can be installed without any alterations to the attic, joists, or vents, this is a rare occurrence. You also need to understand home wiring, electricity, and the control panel.

However, DIY installs are an option, and if you have the knowledge and tools, it isn’t a highly difficult job.

  • From the attic, you need to remove any plywood, flooring, and insulation at the install location.
  • Cut and nail 2×10 pieces of wood just slightly wider than the width of the installed fan.
  • Cut through the ceiling, replace the plywood flooring, and cut a hole for the wiring.
  • Place the fan into the hole, securing it to the bracers with screws.
  • Place the grating and run the wiring through the hole.
  • Plug the fan into an outlet (or install a new one near the fan).
  • Open windows and attic vents and turn on the fan to test it out.

People Also Ask (FAQ)

What is CFM?

CFM stands for Cubic Feet per Minute. This is a measurement of how much air is moved by a fan.

How much will it cost me to install whole-house fans?

The cost will depend on several factors but generally isn’t that expensive. The national average price, according to HomeAdvisor, is between $369 and $876. This may change depending on your specific needs, location, fan installation type, and other factors.

What does standard cooling and breeze cooling mean?

In short form, standard cooling is used to describe the process of heat removal through the process of heat transfer. An air conditioner usually does this with a compressor cycle. Heat is transferred from the air to the refrigerant and moved outside.

Breeze cooling is a term to describe the cooling effects of air replacement. For example, fans move hot air out of a home while bringing the cooler air from outside back in.

How much energy costs will I be able to save if I invest in whole house fans?

Many factors go into the costs to operate a central air conditioner and a whole house fan. Among them, of course, are temperature, duration of use per day, and the number of days per year of use.

However, energy efficiency suggests that whole house fans can typically reduce operation costs in your energy bill by as much as 90%. A more conservative estimate, though, is about 60 to 70% with daily use over the spring and summer months.

How long do these whole house fans typically last?

A whole home fan can easily last 10 years or more. Proper care and maintenance are needed as with any electric or motor-driven device. Some whole house fans even see two to three decades of use when properly maintained.

What maintenance requirements are needed for whole house fans?

Maintenance for the fans is relatively low. You will want to dust the intake vents, of course, since most will not use a filter. Once a year, before the start of the season, you will want to check the power outlet, electrical cords, remote operation, and clean off the fan blades.

Any dirt, dust, or debris build-up should be removed as well. Some models will require annual bearing grease to help promote quiet operation and reduce friction. Your owner’s manual will tell you specific steps beyond these (if any) for proper care of that model of fan.

What are the best brands of whole house fans on the market?

While best brand is a relative term, some of the most popular brands and those with the most positive reviews and customer experiences belong to QuietCool, Air King, and Centric Air. However, there are many brands, and even those that may not be a household name yet are worth looking closer at.

Where is a good place to buy these units?

You can purchase whole house fans in a number of places. Most big box and retail outlet stores will carry them. This list will include places like Menard’s, Home Depot, Lowe’s, and even Walmart. For those that prefer to shop online, two of the best places to find great deals, specials, and service are Amazon and Sylvane.


Whole house fans can save you a lot of money on your electric bill. Where an air conditioner sucks down electricity more than any other appliance, a whole house fan barely uses any. However, whole house fans aren’t for everyone.

If you know you are getting a fan and still don’t know which is the best whole house fan for you, take another look at our top pick. The QuietCool QC CL-4700 is easy to install, quiet and offers a great CFM rate for quickly removing the hot, stale air in your home.
