Direct-drive motors don’t require much maintenance—just ensure that the fan is clean and unobstructed. Belt-driven fans will require new belts every few years, depending on usage. They’re effective at cooling when the exterior temperature is lower than the temperature inside the home. The airflow these fans create can make a space much more comfortable, even if it doesn’t lower the temperature inside very much. The fan sits at the end of an insulated duct to minimize noise, and the other end boasts a louvered grill that shuts when the fan is not in use.

Whole House Fan Vs Attic Fan (Differences?)

An experienced professional should take your attic measurements and install your dedicated circuit wiring and, if needed, your new attic vents. However, due to the vast amount of CFM they deliver, they may require additional joist framing in your attic and extra attic vents. For optimal effectiveness, use your whole house fan in the late afternoons, evenings, and/or early mornings when the outside temperatures are cooler than inside temperatures. For a 2,300-square-foot house, the recommended size of a belt-drive unit is 36 inches (which will cover 6,900 CFM). Both belt-drive and direct-drive units for a 1,900-square-foot house require a 30-inch unit that can handle  5,700 CFM.

Attic Vents

Homeowners can run their Advanced Whole House Fan year around saving up to 75% off A/C related costs. On average, a homeowner can run their Advanced Whole House Fan anytime except for about 4 to 6 weeks of the year, where it may be too hot or too humid. The pricing varies based on the type of Advanced Whole House Fan, the sizing requirements, and the motor type. Many people think that a Advanced Whole House fan cannot be used in humid climates.

ATTIC FANS

This creates an active breeze across you home making you feel instantly 5 to 10 degrees cooler. This is why our products ensure you can experience a relaxing breeze, whenever you need it. If the temperature outside is lower than the temperature inside, the next step is to open 3 to 4 windows, 4 to 6 inches each.

Type 2:  “Insulated Door” Whole-House Exhaust Fan

QuietCool whole house fans are the best choice for climates like Los Angeles County for all homeowners in all cities in Los Angeles County. QuietCool whole house fans can help cool your home whether you live near the coast or further inland. The QuietCool whole house fan then gets rid of all the hot air in your home and cools it much better and faster than an air conditioner, saving you a lot of money on your electric bill.

Step one:  determine how much CFM you need for your home:

These fans are typically 24" to 30" in diameter and they are usually controlled by a wall switch. These AirScape whole house fans are hung from your attic rafters which significantly cuts down the noise and vibrations that traditional fans make. Unlike many other whole house fans, this Cool Attic model has four fan blades (instead of three) so it can move more air.

A whole house fan keeps both your home and attic cool and ventilated. Using a whole house fan to cool your home reduces the amount of time your A/C is in operation during the year, prolonging it's lifespan and the cost to repair or replace your A/C system. Homeowners are saving tons of money on their A/C usage due to the energy efficiency the whole house fan brings. With a whole house fan, A/C usage can be cut dramatically, or even eliminated completely in certain climate zones. The Roof Mount Advanced Whole House Fan Series is our newest and most exciting line of Advanced whole house fans.

There’s a lot to know about how to choose the best whole-house fan, but shoppers shouldn’t lose their cool. The following sections will outline the most important considerations to keep in mind when shopping for a fan to cool an entire home. There are many reasons why installing a whole house fan in your home makes sense. In fact, the inclusion of whole house fans is not the only provision that favors the planets included in title 24. Any handyman, electrician, contractor or DIY homeowner can quickly and easily install a whole house fan in your home, office or commercial space.

Unlike other whole house fans that leak air into and out of the attic, the Tamarack unit creates an air-tight seal. The Tamarack is a unique whole house fan that features self-sealing insulated doors with an R38 rating. The cost to install a window AC is only $150 to $530, but you'll only be able to cool a single room—and not very efficiently. A variable-speed whole-house fan with smart technology could cost as much as $3,600, fully installed.

Some owners choose to run the A/C during the day and the whole house fan in the evening. There are gable vents, roof louvers, intake vents, and soffit and eave vents. According to most building codes, you need 1 square foot of vent area for each 150 square feet of attic floor space. Building codes specify minimums; you may want to increase those to ensure proper ventilation. A whole house fan is a ventilation system designed to cool down an entire house by drawing in cool outdoor air and expelling hot indoor air. Unlike air conditioning, which cools the air using refrigeration, a whole house fan relies on the principle of natural ventilation to create a cooling breeze throughout the home.

But it’s important to remember that Advanced Whole House Fans are not the same as air conditioning and may not work in very hot or humid weather. Never run your whole-house fan with the windows closed because doing so creates negative pressure and backdrafts. Whole-house fan systems draw cool air in from outside and blow hot air out through the attic vents.

To prevent heat loss, you’ll need to build an insulated box to cover your fan during the off-season. The CL-1500 system is available in several sizes ranging from 1,472 cubic feet per minute (CFM) to 6,924 CFM, which are compatible in homes from 750 square feet to more than 3,000 square feet. The CL-1500 includes a remote control that can operate up to 100 feet away from the fan, but it doesn’t come with Wi-Fi support for operation with a cell phone. A fan is a much more energy efficient than a traditional air conditioning unit.

Direct-drive fans are typically the most energy efficient, but belt-driven fans are quieter. Whole-house fans are more affordable than the cost of central air conditioning systems and are quiet and energy-efficient. The Superfan is rated for all homes up to 3,000 square feet, though it is not recommended for homes in very cold climates. The cost is $1,550, with installation estimated at between $400 and $500. Are you tired of paying soaring electrical bills and running your air conditioner day and night in summer? Have you developed allergies, likely brought on by stale, non-ventilated, “shut-in” air?

In addition, you can wire the whole house to a remote controller so you can turn it on anywhere in the home, a very nice feature. To cool the home, ideally, homeowners should open windows or doors on the coolest or shaded side of the home. And after running the whole house fan, close the blinds and curtains on the hottest or part of the house with direct sunlight. Cold air infiltration into the home during winter is a common problem with traditional style whole house fans.
