What is a whole house fan and how does it work?

[@MySliceOfLife101]

I've installed a couple of whole house fans in my day. For areas that cool off somewhat in the evenings, the fan really only needs to be run for 15-30 minutes to evacuate the hot air in the house and replace it with the cooler outside air. Really great and simple technology.

[@qcmanufacturing]

Yes, you know what you’re talking about. The only thing I would add is you can kick it on low speed and run it all night or several hours. Where you from?

[@Juzva8]

I've been running my whole house fan every night, and it's made a huge difference! My electricity bill dropped from $400 to $250 per month

[@qcmanufacturing]

Where are you from? I’m glad you like your system

[@BlockchainToTheFace]

If it’s cool enough outside to run just a fan, you don’t even need A/C, therefore, you’ve been WASTING money and you haven’t really SAVED any.

[@qcmanufacturing]

@BlockchainToTheFace if it is a hot day and cools off in the evening you can run a whole house fan instead of ac because it runs at 1/15th cost of AC. By running running your ac less you will also extend the life your ac system. Ac system only last about 13 years on avg. now you can make them last up to 20 or even 30 years. AC is the most expensive home appliance to run and replace. Whole house fans are the V on HVAC. They aren’t designed to replace AC but run as a companion with your AC system.

[@letterphase]

Would both be a good idea? Attic fan AND a whole house fan

[@WarHeadinc1]

When I get a place of my own. This is what I would like to have.

[@qcmanufacturing]

Yes, it is a game changer. Where are you from?

[@Lyle_918]

We had crank out windows so a attic fan during the rain was so refreshing, almost needed a light jacket.

Awesome thanks for sharing. Where you from?

Attic fans do cool your house down. They remove the heat from your attic s which allows heat from the house to escape. Otherwise, you create a greenhouse effect and your house continually heats up. Just an attic fan alone will keep your house 10-15 cooler than without. Not a major help but instead of 100 outside and 90 inside, you can be at 80 inside without running anything else. Very nice to have in the SW and SoCal with electric prices

[@qcmanufacturing]

Someone knows their stuff pretty good. You’re pretty spot on.

[@TopODaMernin]

@@qcmanufacturing lol I’m a scientist. But yeah, living in SoCal I bring my work home to save money and make my home more comfortable and efficient and the QC whole home and attic fans have been the best I’ve found

[@Aurelisk]

During the day it gets to 110F here. At night, when it's cool, I open the windows and boom, heat is gone.

[@qcmanufacturing]

Where are you from?

[@kriseasterwood2664]

If used correctly they could cool a huge room or two down. We called itban attic fan because it literally connected to an attic. The trick was, you leave the 2 doors open near the "attic fan'" and it would create an incredible pressure that would cool you. I feel like you left alot of information off

[@qcmanufacturing]

Here is some more info. The attic fan you would run when it’s hot because it keeps your attic with in 5-10 degrees of the outside temp at all times. This prevents your attic from getting up to 150 degrees on hot days which makes your ac not cycle on and off. The whole house fan you only run when it’s cooler outside than inside your home. This is usually in the evening, night time hours. If you’re in an extreme hot climate like Texas you would use the whole house fan during the spring and fall and have to use a/c prevent your ac from running 9-10 months a year. That helps your ac last up to 30 years because ac systems only last 12 to 13 years on average. These products are the ventilation piece of the HVAC system. Most homes don’t have any ventilation products.

[@STSwhisperer]

Older, solid mounted and belt driven whole house fans were much quieter and seemed to move much more air than the direct drive options we have today

[@qcmanufacturing]

Have you tried our system out? Our fans are extremely quieter than a traditional fan. We have different models of fans that range from 1500 CFM to 7000 CFM. If you want power you to need to make sure to go with a bigger model.

[@STSwhisperer]

@@qcmanufacturing I have not. I was talking generally. I will have to check yours out. It’s definitely intriguing.

what good does it do if its still hot outside?

[@urielmoralez8036]

Will the attic fan also help with lowering my AC usage? We have a WHF which i run at night.

[@qcmanufacturing]

Yeah, it will keep your attic about an avg of 10 degree difference from the outside temp during the day. So on hot days your attic can reach temps of 140 degrees it will make your attic much cooler and make it easier for your ac cool the house.

[@josealvarado2172]

Hello, im im texas. im in the business of house ventilation and have been for the last 20 years , i remember seeing those old big belt driving fans in old house attics , obviously, this is intended to move and create natural air circulation through out the house by cracking opening doors and windows , not to be used during extreme temperatures? You can't have your house ac running while using it because then you'd be pouring money out your windows, but do you guys get in a modern house issue of dust ,pollen lr debris drawn through the openings? I mean, with people's tendency to be allergic to everything now a days is this a concern for your clients? I imagine you will have to keep room doors and wndows open to create proper circulation? Does this affect pressure in the house ? At long term use have you seeing any damages to paint texture or tape? Specifically on a humid environment as we have here in texas all year round? Thanks.

[@qcmanufacturing]

Yes, we create negative and positive pressure it it won’t affect the home structure. You would never run this fan when it’s hot outside. You only run it when it’s cooler outside than inside so you don’t waste conditioned air. The outside air is normally 2-5x times cleaner than inside of your home. We also make the world’s first MERV 5 rated screen to block out dust and pollen entering the home. These systems are designed to help you cut down on your ac usage in the evening and nighttime. This will also help extend the life of your ac because you’re putting less wear and tear on the unit. You pair up an attic fan with our whole house fans and you have the best ventilation system money can buy.

[@DanMaul-ip1is]

That makes no sense if you’re in the south drawing in humid air, I guess if you didn’t have AC. We had one growing up and it worked in the PNW to draw in cold morning air. But it still gets hot in the afternoon

[@qcmanufacturing]

If you live in a hot market like Texas or Florida whole house fans work great during the spring and fall. Most people in those markets run their ac 10 months a year and you can cut it down to 3-4 months with a whole house fan and attic fan combo.

[@israelmondragon2664]

What if we also have a swamp cooler running. Im in Hesperia CA

[@qcmanufacturing]

You can still run your swamp cooler. I know some customers that use the whole house fan to pull the cool air from the swamp cooler throughout the house.

[@LuckyPullz]

What if it’s really hot out

[@qcmanufacturing]

Here is a quick run down on whole house fans and attic fans. An attic fan you would run when it’s day or night including when it is hot outside because it keeps your attic with in 5-10 degrees of the outside temp at all times. This prevents your attic from getting up to 150 degrees on hot days which makes your ac not cycle on and off. The whole house fan you only run when it’s cooler outside than inside your home.

[@priesthoodculture1877]

Wow...very educational. I want this cooling feature. But where I live we don't normally build attics.

[@priesthoodculture1877]

@@qcmanufacturing I'm in the Caribbean. When we build we will be installing AC and this type of ventilating is a nice option. Every year it gets hotter and hotter. I will have to consult you when we're going to build.

@priesthoodculture1877 yes, let me know

[@speedyz28]

Wouldnt it create neg pressure in the living space and positive pressure in the attic ? I have a bunch of solar ones laying around that i never installed. Is there any benefit of putting one in the gable to simply push air through the attic alone ?

[@rblhlbly]

So... It's a more quiet version of an attic fan...

[@qcmanufacturing]

We make smart versions where you can control your attic fan from your phone and monitor the temperature and humidity levels. We also use ECM motors that can use as low as 22 watts when running on low speed.

[@ruthgentrycorlis5653]

How do you fix one when it quits?

[@qcmanufacturing]

Which brand do you have? Most companies make cheap attic fans. Our attic fans have a 15 year warranty. Most likely your motor is burnt out.

[@Laguna2013]

so you have to shut it off when you're running the ac?

[@qcmanufacturing]

Yes, you run your whole house fan in the evening, morning and night time hours when it’s cooler outside than inside. You will use your ac during the day when needed.

[@joeyboudreaux8504]

Yea, no. I don't want the 92-degree(right now, in May. It'll be 100+ come June) air being sucked in from out side when my air inside is 65 🤣🤣🤣🤣🤣

[@monicalifornia_]

If you live in a State that doesn’t get any relief from the heat in the morning or at night, you definitely wouldn’t need this. Out here it is an absolute lifesaver when it can reach 100 during the day but drops to 70 at night.

[@TopODaMernin]

Your air inside is 65 because you are running your AC…. Wtf… lol

[@sticksbass]

seems its only good if everybodys gone all day and comes home when its cooler outside.

[@qcmanufacturing]

You’re missing the entire concept. Every where across the country there is a 20-50 degree temp swing from day and night. You use the whole house fan when it’s cooler outside than inside. This is usually the morning, evening and nighttime hours. When you run the whole house fan all night you pre cool the home to what ever the low temp is for the day. Now it’s going to take a lot longer for your house to heat up and if you need to use AC it’s minimal. AC system only last 12 years on a national avg. it’s also the most expensive appliance to run. So when you can cut out half of your ac useage you can double the life of your AC system and save money on your energy costs. Then there is the comfort and IAQ benefits as well.

[@sticksbass]

@@qcmanufacturing is it not already precooled from running the ac when its too hot to use the hhf?

[@qcmanufacturing]

Your ac during the summer can cool your home down to the low 70s where a WHF can cool it down to low the 60s and it run at 1/15th cost. Whole house fans are the V in HVAC. You want both the AC and the whole house fan in your system. It will make your HVAC system twice as efficient when used properly.

[@sticksbass]

@@qcmanufacturing how can whf cool it that much when its still 90 outside at night?

[@qcmanufacturing]

@sticksbass where do you live? There’s only handful of places that don’t cool off at night during the summer. In those climates you normally run your ac 10 months of the year and you can use the WHF during spring and fall and cut down the ac useage to only around 3-4 months a year.

[@jon-michaellane3781]

Where is this cool fresh air coming from outside?? Its hot af out here.

[@qcmanufacturing]

You don’t run it during the day. You only run it when it’s cooler outside than inside. If you live in a hot climate zone like Texas or Arizona the fans work great during the spring and fall. If you live in California it’s cools off every night during the summer just like the upper west coast and pacific north west and mountain states.

[@AlexDeramus]

Nah I had a whole house fan, it used a lot of electricity to run it. Maybe mine was just older. But it used a lot of electricity.

[@qcmanufacturing]

You probably had a traditional whole house fan. They use the old school motors that aren’t efficient and gave the product bad a name because of it. Our advanced WHFs use ECM motors that run equivalent to a couple led light bulbs
