Ceiling Fans are HVAC Heroes in High Performance Homes

See how our forever home's 7 ceiling fans play a pivotal part in our performance-tuned house's HVAC system. Among the most efficient fans in the world in 2020 (420 CFM generated per Watt), they are a silent and beautiful reminder of the invisible dynamics at play around us all day, every day.

Hi Corbett, nice informational video.
I installed a 72” fan in a room (420sq. Ft) w/ cathedral ceiling 13’ high with a drop rod length of 2’, the fan is 10’ from the floor now.
Is that ok or should I drop it another foot closer to the floor yo make it 9’ above the floor.
It just looks like it a little higher than the rest of the fans in the house that are about 9’ from the floors.

Great video, what is your spacing for the room with the fan? What’s the dimensions of the room ?

Thanks for sharing. Would you advise on using this for a 22ft vaulted ceiling? Heat gets trapped up there and we're trying to circulate that heat better.

I like the dipswitches.. So that when you loose power the fan doesnt forget which controller it goes to. Also no annoying combination of buttons to program it.

Do you have suggestions on the best low-cost efficient ceiling fans? It seems like the main companies making high efficiency fans (haiku and fanimation) are also basically luxury brands. I'm frustrated that I can't get a basic ceiling fan with blades that aren't flat paddles. I recognize that there are other elements to an efficient fan (eg DC motors) but I imagine the largest is really the fan blades. I've never seen retrofit blade options either.

Really enjoyed the video. Watched the whole thing. Have been experimenting with this myself prior to watching the video. My daughter’s room and the guest room are like 8 degrees lower than our bedroom down the hall. Currently have the hot room running counter clockwise one in the guest room fan (no fan in her room) running clockwise. Temperatures are higher in the bedrooms but not equal, at least more comfortable.

Very much into being energy sufficient, more for my wallet instead of the environment. Can’t wait to see more videos

I am building a traditional adobe home in Arizona's high desert. The climate is fairly moderate - not the scorching heat of Phoenix nor the bitter cold of high mountain towns. It is a modest 1400 square foot house and only one story. I went to great lengths to provide cross-ventilation with high transom windows across the room from the cool air registers. I also plan to install some in-ceiling vent fans to serve the same function during the winter when it is too cold to vent with open windows. Since I will not have volume ceilings, I doubt that I need circulation fans. Do you know of any way of modelling airflow (without paying an engineer a gajillion dollars to do it for me) to find out how my proposed system works BEFORE I build the house?

All of your fans are running in the pull vs push direction. I have always wanted to understand which was best. I was hoping to see something in this video about that. Is it an interesting enough topic for you to make a video about?

MY MOM JUST INSTALLED 1 AND I JUST WANNA MAKE SURE LIKE IF ITS ON HIGH WILL IT FALL OFF ITS IN ARE MOVIE THEATER BECAUSE IT WAS TOO HOT

Very well explained as always Corbett.

I was strongly considering Big Ass Fans since they seemed to be the best-balanced and highest quality fans I could find. The price made my eyes water, but I couldn't find anything else with anything as reputable. I'll have to look more into these. They're beautiful.

Now that you've had them for a while, are they still quiet and good quality?

Not all of his information is correct..

Video volume way too low. Remember, audio quality is more important than the video. Take care.
