What Are Whole House Fans

Reduce Your AC Costs by 90 Percent

We use our heating and air conditioning almost every day of the year. While we enjoy our cooling and it keeps us safe from extreme heat, we don’t always like the bill we get at the end of the month. Whole house fans solve that problem altogether. In fact, whole house fans reduce cooling costs by 50 to 90 percent. They cost very little to operate and deliver a lot of benefits.

Whole house fans are easy to use, economical and good for the environment. They are efficient, last long and require almost no added maintenance. Whole house fans are an easy choice to create a healthy and enjoyable home through natural cooling and ventilation.

What Are Whole House Fans?

A whole house fan is a large fan installed in the attic. These fans do not work alongside traditional air conditioning but they do aid in reducing the heat load inside of the home. These fans also connect to the attic vent, which is where hot air from inside the home exits. In doing so, whole house fans reduce the amount of energy needed to cool the home.

Generally, there are three different types of whole house fans. The standard fans are the largest but also the loudest. While the standard fan works the most quickly, it also can leak a great deal of energy on the months that you do not need cooling.

Next is the insulated fan. This design works just the same as any whole house fan, the only difference being that comes with an insulation feature. These fans are best for homes in colder climates that need to block out frigid temperatures during the winter.

HVAC contractors’ favorite choice is the inline whole house fan. These are effective at cooling and blocking heat loss during winter months.

Inline whole house fans are made of the:

  • Intake port
  • Fan housing
  • Damper doors
  • Duct

When the fan is on, it pulls air in through the intake port. From there, air travels through the duct. For most whole house fans, the duct is roughly around 10 feet long. This allows your technicians to install the whole house fan with plenty of room to spare, positioning it in the best way possible. They are also connected to the attic vent. Hot air from inside the home is dumped outside through the attic vent. Damper doors are in place to stop warm air from exiting during the cooler months of the year, which prevents unwanted heat loss.

How Do Whole House Fans Work?

The basic design of a whole house fan is very simple. The fan pulls cool air in from open windows and doors and pushes hot air out through the attic vent.

In order for them to work properly for cooling, outdoor temperature must be lower than indoor temperature. This is rather simple to achieve. Most homeowners opt to open windows and doors during the morning or at night when the hottest time of the day is over. Since cooler air is invited in during these times, the home continues to remain cooler despite outdoor heat.

This also reduces heat load inside of the home. What is heat load? Basically, heat load is how hot you let it get inside of your home. For traditional cooling, a high heat load is very bad. High heat load creates more work for your air conditioner, much of which could have been prevented. Additionally, a high heat load prevents the home from reaching the cool temperature set on the thermostat.

With the help of a whole house fan, heat load no longer becomes a harmful issue. They remove excess heat, keeps the home as cool as naturally possible and prepares the home for efficient air conditioning.

Can Whole House Fans Save You Money?

They can and do save you a lot of money. They use only a tenth of the energy your central air system uses. So, for homeowners who can get away with using whole house fans only, they reduce their cooling spending by 90 percent. This makes them the most economical and eco-friendly method to cooling.

What are some other benefits of utilizing whole house fans?

  • Reduces energy costs
  • Elevates home comfort
  • Improves indoor air quality

Whole house fans do a wonderful job of aiding air conditioning from the central air system. Because they manage the heat load, they reduce the amount of work your AC has to do in order to reach the temperature you set on the thermostat.

They also help remove stale and dirty indoor air because they pull in cleaner air from outdoors. How important is this?

Indoor air is between five and 100 times dirtier than outdoor air. Why? There are so many sources for indoor air pollution and not enough ventilation to combat bacteria and particles in the air. Using whole house fans changes that. Because they pull outdoor air and pushes hot indoor air out, you have cleaner and fresher air to breathe everyday in the safety of home.
