A high efficiency Advanced Whole House Fan is a type of ventilation system that is meant to cool the whole house by pulling cool air in through windows and letting hot air out through the attic. Most of the time, these fans are stronger and more efficient than traditional Advanced Whole House Fans. This means that they can cool a house faster and better while using less energy.

Whether hunting for a ducted fan or a more basic model, you’ll be sure to find some good options for everyone among these leading products. It will take only as low as ten minutes for a whole house fan to cool a house. The larger the house, the more will be the CFM of the fan, and maybe you need to open more windows. There are no clear guidelines on how many windows need to be open, as this is usually found out by trial and error. Opening too many windows will spread out the air circulation, and hence that is not recommended.

You can also set up the system so that it only runs when the air conditioning system is running, or use pre-cooling coils. Like exhaust ventilation systems, supply ventilation systems are relatively simple and inexpensive to install. A typical supply ventilation system has a fan and duct system that introduces fresh air into usually one -- but preferably several -- rooms that residents occupy most (e.g., bedrooms, living room). This system may include adjustable window or wall vents in other rooms. Exhaust ventilation systems are relatively simple and inexpensive to install.

Our Whole House Fan systems come out-of-the-box ready for easy installation and include free lifetime support. Consider your local climate and whether your area experiences cool evenings and nights, as this will affect the overall effectiveness of the whole house fan. A whole house fan can turn over the air in a home up as much as six times an hour, depending on the size of the house. With new viruses emerging and homes and buildings being built tighter and tighter, it is very important to make sure the air quality inside your home is good.

This is why Advanced Whole House Fans Work in just about every climate zone. As soon as that temperature swing kicks in and it cools off outside, it is the perfect time to run your Advanced Whole House Fan. The climate in which you live in is the main factor that will dictate if you should install a central air conditioning system or an Advanced Whole House Fan.
However, they are most cost-effective in climates with extreme winters or summers, and where fuel costs are high. In mild climates, the cost of the additional electricity consumed by the system fans may exceed the energy savings from not having to condition the supply air. In the summer, an energy-recovery ventilator may help to control humidity in the house by transferring some of the water vapor in the incoming air to the theoretically drier air that's leaving the house. If you use an air conditioner, an energy-recovery ventilator generally offers better humidity control than a heat-recovery system. However, there's some controversy about using ventilation systems at all during humid, but not overly hot, summer weather. Some experts suggest that it is better to turn the system off in very humid weather to keep indoor humidity levels low.
With an attic fan, the constant flow of air in the attic lowers the overall humidity level and helps keep the attic healthy. QuietCool Solar Attic fans are the obvious next step in our constant mission for eco-friendly home cooling. These supremely-efficient fans utilize the sun for power so you can use even less energy than with a traditional attic fan. These fans also possess the ability to cool 24 hours of the day due to their innovative inverter. Our Smart Attic Fan Series offers your home a healthier attic, a cooler place to live, and a reduced A/C bill. Using our Smart Control App you can set presets, turn on and off whenever you need, and see the exact temperature and humidity of your attic space.
Types of Whole House Fans
We then compared these fans’ power, design, and prices to ensure they offered enough value to make our lineup. Those that didn’t were cut, while those that did were given awards based on their strengths. In fact, the inclusion of whole house fans is not the only provision that favors the planets included in title 24. In addition to lowering utility bills of new homeowners, this also helps to significantly reduce the strain on limited energy supplies throughout these zones of California. The main difference between a heat-recovery and an energy-recovery ventilator is the way the heat exchanger works.
Since these fans are very powerful, running them with closed windows will create negative pressure inside the house, which can adversely affect the working of furnaces and HVAC appliances. So if your air conditioner is switched on, the fan will remove that cool air from the house, which is counterproductive. So you cannot have an air conditioner and a whole house fan working together. Before switching on your whole house fan, make sure that the air conditioner is switched off.
An in-line duct heater is another option, but increases operating costs. Like both supply and exhaust systems, balanced ventilation systems do not temper or remove moisture from the make-up air before it enters the house. Therefore, they may contribute to higher heating and cooling costs, unlike energy recovery ventilation systems. Also, like supply ventilation systems, outdoor air may need to be mixed with indoor air before delivery to avoid cold air drafts in the winter.
During the summer months it can get really hot upstairs in a 2 or 3 story home. Sometime not even an air conditioning can cool off the upstairs of a home on a hot summer day. Advanced Whole House Fans are the best way to cool a hot upstairs and allow you to stop having those hot sleepless nights. Depending on the size of the Advanced Whole House Fan you are installing, you can expect to pay between $500 to $3000 installed. The pricing varies based on the type of whole house fan, the sizing requirements, and the motor type.
This is counterproductive, and it hugely affects the efficiency of the whole process. So the attic stairs must be insulated and closed before starting a whole house fan. Our whole house fan offers quiet ventilation that draws fresh, clean air into your home while expelling hot, moist air through rooftop vents. These models don’t move as much air as standard fans, but they tend to run quieter, so they can be run all night. Like standard fans, these units are usually installed in a hallway, but some smaller models are specially designed to fit in between or around existing trusses or joists to make installation easier. Cooling using a whole house fan can substitute for an air conditioner in some climates.
The effectiveness of a whole house fan depends on the availability and positioning of windows for air intake. Ensure that you have enough windows strategically placed to facilitate the air circulation. Installing a whole house fan is tricky and should be done by a professional. An experienced professional should take your attic measurements and install your dedicated circuit wiring and, if needed, your new attic vents.
