You can choose the amount of airflow by setting the fan to one of two speed settings. While the Cool Attic doesn’t come with a temperature switch or a timer switch, it does have both an on/off switch (which DIYers can replace with a Wi-Fi model) and a high/low switch. Keep in mind that the belt will need periodic replacement (depending on the weather and amount of use) and that the fan can grow louder when it starts to wear out. Energy recovery ventilation systems require more maintenance than other ventilation systems.

The air will also come through the windows on the ground floor, blowing through the stairs into the first floor and into the attic. You can limit this circulation by opening more windows on the first floor. Also in a two-story house, the ground floor will remain relatively cooler, it is the upper floor that usually needs cooling.
What is the best time to run a whole house fan?
Installing a small fan in a large house won’t pull cooler air into the space effectively, and installing a large fan in a small home might feel like living in a wind tunnel. Central air, window air conditioners, and split AC units aren’t the only ways to keep a home comfortable during hotter weather. For folks who’d prefer a cooling method that draws less on the energy grid and provides a bit more fresh air, the best whole-house fan might be the way to go.
Its 1,000 CFM is on the lower end of the spectrum, so keep that in mind if you’re looking for a fan with a little more power. Its barometric pressurized dampers help to create a tight seal and reduce the chances of cooling loss between the attic and the rest of the house. Keep in mind that since this fan is on the larger side, it's likely going to be more of a challenge to install. A separate control panel features an easy to read LCD screen, which shows the desired temperature as well as the actual temperature, and allows you to set timers and alarm warnings. It also gives the option of choosing between 10 speed settings, which is considerably more than similar options.
With an energy-recovery ventilator, the heat exchanger transfers a certain amount of water vapor along with heat energy, while a heat-recovery ventilator only transfers heat. This infographic is a quick overview of 18 interesting facts you didn't know about ceiling fans.Feel free to share this infographic on your website by copy-pasting the code... Whole house fans have high air flow rates, and many will be able to do a complete air change in a minute or two. Therefore, if the outside air is cool, the house will be cooled within a few minutes.

Depending on the size of your home, a brand new central air system installed can cost up to $20,000 and is a very complicated installation. A Net Zero home is a home that creates the same amount of energy as it uses, meaning its load is effectively zero on the electricity grid. The goal for California is to get to Net Zero home construction by 2024. Since A/C makes up between 60 to 80% of homeowners utility bills, an Advanced Whole House Fan is one of the best ways to get to a Net Zero home cost effectively. According to the United Stated Department of Energy, Advanced Whole House Fans are the most cost-effective way to cool your home. UCLA states that Advanced Whole House Fans can eliminate A/C usage in 10 of the 16 climate zones in California.
This allows your attic to stay within 10ºF of the outside temperature at all times when the fan is running. Without an attic fan, your attic can get up to 150ºF during the summer, which can ruin the integrity of your home and cause high electric bills. Not everyone can, or wants to, cut into their ceilings or walls to install a whole-house fan, and Air King’s 20-inch whole-house window model is an attractive choice for those in that category. When installed in an upper-level window, this fan pushes warm interior air out and replaces it with fresh air drawn from open windows on the lower level. The Air King also features three speed settings, moving up to 3,560 CFM of air.
They need to be cleaned regularly to prevent deterioration of ventilation rates and heat recovery and to prevent mold and bacteria on heat exchanger surfaces. In climates with warm humid summers, depressurization can draw moist air into building wall cavities, where it may condense and cause moisture damage. By installing a whole house fan, you could save money on your energy bills since whole house fans don't use as much electricity as AC units do and they add value to your home. Southern and coastal regions of California have what's considered a Mediterranean climate, with dry summers and slightly rainy winters. Because the sea typically creates desirable statewide temperatures with cooler summers and warmer winters, most Southern California homeowners rely on their AC units as their main source of cooling.
Insulate ducts located in unheated spaces, and seal all joints with duct mastic (never ordinary duct tape). Dial in your efficiency, temperature, and air freshness with the Comfort Control Remote. With 7 variable speed options, you’ll be able to balance energy consumption with circulation and comfort. The optimized blade shape works harder so the motor doesn’t have to which saves you money and extends the life of the unit.
For desert climates, the recommendation is typically 3 CFM per square foot. For more inland climates, the recommendation is typically 2.5 CFM per square foot. For example, for coastal or mountain climates, the recommendation is typically 2 CFM per square foot. Comfort is essential for every home and our products offer it with a constant and clean current of fresh air. At QuietCool, integrity, diligence, and innovation are integrated into everything we do. These core values are what has allowed us to pursue our vision of eco-friendly whole-home cooling and ventilation across the country.
If you’re looking for more cool for your cash, then meet the new Engineered Performance Series Whole House Fans from Solatube. The powerful circulation provided by our Whole House Fans means your A/C unit can chill and only work when needed—significantly lowering energy consumption and your bills. Rest easy knowing that the Engineered Performance Series Fans have everything you need to keep you more comfortable and healthier year-round. Since whole house fans use a whole lot less electricity than AC units do, they're helping to decrease the pollution and energy grid burden that would otherwise occur.
The best system combines an attic fan and a Advanced Whole House Fan to cool, ventilate, and exhaust the entire home, day and night, and year-round. The humidity level is usually high in the early morning and drops down to its lowest point in the late afternoon. By the time early morning comes, the homeowner will shut off the Advanced Whole House Fan and enjoy a cooler house all day long. 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.
Moving a joist in order to frame out a box for the fan, or installing additional attic venting might wind up costing more than the fan itself. Another disadvantage is that during the winter, the vented opening works like an open window, giving warm moist air an easy path out and into your attic. To prevent heat loss, you’ll need to build an insulated box to cover your fan during the off-season. It draws in the fresh air and ejects the warm, stale air through a vent in the attic. The result is fresher air and more comfortable temperatures indoors while potentially lowering the electric bill (due to running the air conditioner less).
