Whole House Fans

While HVACs and air conditioners are powerful tools, they can be expensive and, in some cases, completely unnecessary. Depending on the region and time of year, in many climates a whole house fan may be all that’s needed to cool the entire home. Whole house fans can create the comfort your home needs without HVAC or a/c. They can also supplement these solutions, ensuring once the house is cooled, it stays that way. Whole house fans work with all types of circulating fans for noticeably less energy than you’re utilizing for the HVAC or an a/c.

How They Work

A whole house fan pulls air from open windows. It exhausts the air through the roof and attic. While elements like floor plans, size of house and climate have to be considered, on average, whole house fans offer between 30 to 60 air changes per hour. You will have the option of choosing air change rates.

Installing the Whole House Fan

If you want to avoid all the pitfalls associated with these systems, such as noise, it is recommended you use professionals like the techs at Dollens. One installer may cut corners to save a little money. Dollens promises a safe and efficient system. This means using felt or rubber gaskets to minimize noise. Our pros know large capacity fans operating at low speed make less noise than even the smaller fans running at high speeds and will install your system accordingly.

Whole house fans come in two types. The direct drive fan has blades which are attached to the motor shaft. A belt driven system comes with a separate blade assembly. It uses a belt and pulley to circulate air. The belt driven fan also tends to be quieter than the direct drive system.

Safety

Only a professional San Jose installer will see that there is proper ventilation. Otherwise, the system could create a backdraft that can affect water heaters, furnaces and gas dryers. This can lead to hazardous conditions, such as putting carbon monoxide into the environment. This is not something you want for your family. But the only way to make sure it doesn’t happen is by having a professional install, maintain and repair your whole house fan.
