Whole House Fan

In most regions, whole-house cooling using a whole-house fan may replace an air conditioner for most of the year. Many families find that whole-house fans provide enough summer comfort even in hot weather. Your central heating and cooling system’s ducts can also be modified to provide whole-house cooling, in addition to whole-house fans. 

This energy-saving device works by drawing cold, outside air into your home and directing it out your attic vents. This keeps the air in your home cooler than an air conditioner. These whisper-quiet, energy-efficient marvels are the market’s leading domestic cooling and ventilation device.

You can switch off your most expensive appliance like air conditioning. Instead, use a whole house fan to increase your home’s air quality and comfort for pennies per hour.

Using and Installing a Whole-House Fan

Installing a whole-house fan is complex and should be left to the pros. Your dedicated circuit wiring and new attic vents should be installed by an experienced expert who takes your attic measurements.

To exhaust the fan’s air outside, attic ventilation will typically need to be improved. You’ll need 2 to 4 times the average area of attic vents. That’s for every 750 cubic feet of fan capacity.

The resistance provided by the louvers and insect screens is included in the net-free area of a vent. Therefore, for the best whole-house fan performance, more vent area is ideal.

If your fan doesn’t come with a winter cover, you may buy one or make one yourself. Build a well-sealed, hinged door for the fan opening.  Make sure it is easy to open and close when switching cooling techniques as the summer weather changes.

When using these big exhaust fans, use caution. For example, open windows around the home to avoid a forceful and focused suction in one area.

In addition, the fans might produce a backdraft in your furnace, water heater, or gas-fired dryer without adequate ventilation. This will result in drawing combustion products like carbon monoxide into your living space. 


Why use a whole-house fan?

Are you still experiencing the sweltering heat this summer? As much as we enjoy our air conditioners, there are some excellent alternatives. Don’t forget to think about the advantages of whole-house fans. 

They swiftly chill your house by drawing cold air through open windows and pushing hot air out through the attic. As a result, they use much less energy than a typical air conditioner. In addition, whole-house fans are eco-friendly since they require less power and no refrigerants to cool your home. 

They constantly circulate the air in your home, keeping it fresh and eliminating smells from cooking, smoking, and household cleaners. They operate quietly and endure for years if correctly placed. 

Whole-House Fan vs. Attic Fan

A whole-house fan and an attic fan have many similarities. While both works to keep your home cool, they perform different functions. A whole-house fan brings cold air in via the windows.

It may considerably reduce your home’s temperature in less than an hour, depending on the outside temperature. The primary function of an attic fan is to expel heated air from your attic area. Both HVAC accessories can help you save energy and cool your home.

Even so, a whole house fan has a more direct influence on the temperature of your entire home. Hence, as a result, the name.


Why is a whole-house fan worth it?

Immediately feel 5-10 cooler

The vital air blowing through the home windows allows homeowners to feel 5 to 10o cooler within seconds of putting on the whole house fan.

Save up to 50-90 percent on air conditioning costs

Homeowners are saving a significant amount of money on their A/C consumption. This is because of the energy efficiency provided by the whole house fan. In addition, a whole-house fan can significantly reduce or even eliminate the need for air conditioning in some climatic zones.

Extend the life of your air conditioner

Using a whole-house fan reduces the number of times your air conditioner is turned on throughout the year. With a whole-house fan, you’re extending your AC’s life and decreasing the cost of fixing or replacing it.

Maintain a cool attic

Whole-house fans may also reduce the temperature in your attic by up to 50 degrees. A heated attic heats the inside of your home and can cause problems with attic-located appliances. A whole-house fan keeps your home and attic cool and aired at the same time.

Assist in keeping the planet green

Minimize your energy use with a whole house fan. You can reduce your carbon footprint while also lowering your energy cost and helping to keep our planet healthier.

In the winter, heat and ventilate your home

In the winter, homeowners can run a whole-house fan for a few minutes during the hottest parts of the day. Swiftly bring in the fresh air and exhaust stale, stuffy air.

With fresh, outside air, you'll feel revitalized, relaxed, and at ease

In today’s world, one of the top concerns of homeowners is indoor air quality. The whole-house fan cools your home and improves the air quality, creating a pleasant and comfortable atmosphere for everyone. Every 3 to 4 minutes, a suitably sized real house fan wholly exchanges the air volume within the residence.

The distinction between whole-house fans and air conditioning

Like an air conditioning system, a whole-house fan can cool your home, but in a completely different way. A/C systems work well, but they are significantly more expensive to install and operate. Most likely the single most expensive appliance in your house. Resulting in more significant energy costs during the warmer months of the year.

Central air conditioning works by passing the air inside your home via a condense. This closed-loop system provides no improvements to indoor air quality because it just recycles the current air in your house.

Air conditioning is a far more complex and energy-intensive operation than a whole-house fan. When colder outdoors than inside, simply open a window and turn on the whole house fan. This will bring in cold air while exhausting heated air.

The only advantage of an A/C system is that you may use it regardless of how hot it is outside. But a whole house fan should only be used when it is cooler outside during the year’s warmer months.
