User questions & answers

Question:	Can you use the fan without the thermostat feature? I don't want it going on and off all night long
Answer:	I think the other replies were with older models? I just purchased this model and there's no issue with opting out of the thermostat feature. As noted in the instructions, to get to continous air flow, you just keep clicking the button through the modes (first you click throught the various thermostat temperatures, and then you get to "high" or "low" as options. If you click high or low either one will stay on continously. Both options are extremely quiet. It sounds like the person who had a louid nose on the low setting had a defective fan.
Question:	I want to use this in a stand-alone one room dance studio with only one window. If it's very hot outside, will this really keep it cool inside
Answer:	It’s not an AC unit so it will only be as cool (or slightly less hot) as the air from the source. That being said you could use this fan on Exhaust to suck hot air out and use a tower fan to create a breeze in the room. But to cool a room on a 90+ degree day, I’d recommend a window AC. This fan will circulate air tho, so it’s not a bad place to start.
Question:	I need the CFM and decibel (noise) ratings on this fan. These are my two most crucial criteria, but no one shows them
Answer:	This is our second window fan. I don't remember what brand/model etc our first fan was, but the CFM WAS WAY higher than this Holmes fan. My assumption is by lowering the maximum fan speed & thus drastically lower the CFM, they can advertise the fan as being quieter and using less energy. ***We have used this fan for 2 years and we DO NOT recommend it if you are looking for a high CFM (volume) fan***
Question:	Hey all, how are your fans holding up with moderate to heavy use? over 2yrs? 3yrs? more? let me know, thanks
Answer:	I’ve been using an older version of this fan for about 20, yup, 20 years. I use it in a garage studio. Sometimes it runs for months 24/7. It’s slowing down, tons of dirt and mysterious things on it. While it is exhaling i spray wd30 on it till it speeds up again, lol. I have absolutely punished this fan. But like I said, I run it all year, summer and winter. One side died about 4 years ago, but the other is running as we speak. The reason I saw this is because I was looking to see if they still made it. Yay they do; and it is very quiet. Next paycheck I’m getting a new one. I love the intake exhaust function,brilliant! So happy they’re still available. Can’t go wrong, and not a lot of money.

Holmes Dual Blade Twin Window Fan

It's designed to fit double-hung, vertical-slider, and casement windows.

One Touch Thermostat

Set and control your fan speed and temperature for optimal air flow and comfort with 2 digital comfort settings.

Reversible Airflow

User questions & answers

Question:	If the power goes out, will this fan come back on on its own when the power is restored, or so you have to turn it back on yourself
Answer:	I think the other replies were with older models? I just purchased this model and there's no issue with opting out of the thermostat feature. As noted in the instructions, to get to continous air flow, you just keep clicking the button through the modes (first you click throught the various thermostat temperatures, and then you get to "high" or "low" as options. If you click high or low either one will stay on continously. Both options are extremely quiet. It sounds like the person who had a louid nose on the low setting had a defective fan.
Question:	What are the dimensions of this fan
Answer:	It’s not an AC unit so it will only be as cool (or slightly less hot) as the air from the source. That being said you could use this fan on Exhaust to suck hot air out and use a tower fan to create a breeze in the room. But to cool a room on a 90+ degree day, I’d recommend a window AC. This fan will circulate air tho, so it’s not a bad place to start.
Question:	Just received and only one fan is spinning, is it defective? I tried switching from exhaust to intake, left blade doesnt spin at all
Answer:	This is our second window fan. I don't remember what brand/model etc our first fan was, but the CFM WAS WAY higher than this Holmes fan. My assumption is by lowering the maximum fan speed & thus drastically lower the CFM, they can advertise the fan as being quieter and using less energy. ***We have used this fan for 2 years and we DO NOT recommend it if you are looking for a high CFM (volume) fan***
Question:	Our window slides from the side. Can this fan be place vertically instead and then close the window against the long side of it to secure it
Answer:	I’ve been using an older version of this fan for about 20, yup, 20 years. I use it in a garage studio. Sometimes it runs for months 24/7. It’s slowing down, tons of dirt and mysterious things on it. While it is exhaling i spray wd30 on it till it speeds up again, lol. I have absolutely punished this fan.

So happy they’re still available. Can’t go wrong, and not a lot of money.
Question:	Can you use the fan without the thermostat feature? I don't want it going on and off all night long
Answer:	The app. There are 2 place I have found that you can turn the detection off. On the live video page and also in the settings
Question:	I want to use this in a stand-alone one room dance studio with only one window. If it's very hot outside, will this really keep it cool inside
Answer:	The actual battery life of the doorbell depends on the number of wakeups and accesses per day and of course, the recording time will also matter. Usually, in standby mode, it can last for over 3 months(10 times wake-up per day). And it can wake up at least 1000 times when it is fully charged. Besides, as this product uses PIR thermal detection, there are two triggering principles: 1) when there is a temperature difference, 2) when there is a moving object. So we recommend not to place the doorbell too close to the street or the crowds, in order to avoid unnecessary wake-ups due to the temperature differences caused by the vehicles or personnel passing. *Please install the doorbell camera in a place that is away from direct sunlight or street lights for better performance.
Question:	I need the CFM and decibel (noise) ratings on this fan. These are my two most crucial criteria, but no one shows them
Answer:	This is app driven, not pc based---unless of course you have an app driven tablet or a two in one device that can access Google Play services. Check for iTunes compatability.
Question:	Hey all, how are your fans holding up with moderate to heavy use? over 2yrs? 3yrs? more? let me know, thanks
Answer:	There is a toolkit pack including all necessities in the package for you. A 3M double-sided tape is included as well.

Actual blade is 6". IT DOESN'T Have "ELECTRONICALLY REVERSABLE MOTORS". I was surprised the box says "Manually reversible". In all my years, I Never encountered a "reversible fan" that meant you can reverse the entire fan! Of course! You can do that with ANY house FAN EVER MADE! This listing is FRAUD.

User questions & answers

Question:	Can this fan be installed in the ceiling
Answer:	Yes, I installed in a 16 inch opening that used to be a swamp cooler, with a weather proof bell on the roof. The vents open more than 1/2 way on high speed and it draws air in from any windows I open. It is not any noisier than a room fan, T.V. & conversations are easily heard. I do not use the speed controller, just installed a plug in the shaft and use an Alexa receptacle to turn off & on. 2x4 frame & long screws keep it secure & vibration free.
Question:	can two of these fans be wired to a single power cord and run properly
Answer:	The mfgr. specs say that this fan draws 1/5 amp when on. So wiring 2 fans to any 15 amp circuit/breaker is fine. I have 2 of these wired to one single 15 amp breaker /wire or power cord.
Question:	what direction does the air flow? Does it flow in through the shutters or out through the shutters
Answer:	Air flow go’s out through the shutters very powerful if you get it with the speed control works amazingly great
Question:	I was thinking about an indoor application: is it very loud on the higher speed setting
Answer:	"loud" is hard to quantify. I'm using this as a window fan, and I'd rate it a little less noise than the typical 20" box fan on high. However, it moves much more air than the box fan. The speed controller that comes with the fan will make *more* noise because it causes the motor windings to ring. I find it very annoying and prefer to run the fan without the control. Mounting the fan using isolating rubber washers so that there is no direct contact between the fan and the mount helps to reduce the noise transmitted by vibration to the window frame. It's best to mount it to a material such as MDF or melamine-covered MDF instead of plywood or OSB, because MDF is better at damping vibrations--the reason why it's used in speaker enclosures instead of plywood.

User questions & answers

Question:	what is the CFM of this fan and how many speeds does it have
Answer:	The fan is 3 speeds in both directions. I have to admit, though, that I never use the "intake" settings.
Question:	Is this fan noisy
Answer:	Hi Bob! The 2 Air King models that I have is totally reversible. 3 speeds (Lo, Med, High) in both directions; in and out. On Low it draws only 61 watts of current, 76 on Medium and 90 watts on High and blows like a tornado on high. Hope this helps. ~Don

Answer:	Mount it on the outside of the window frame. You'll still get full use of the fan. It's what I do on my enclosed porch to draw air though my house.
Question:	Can this fan be mounted in a ceiling horizontally without any issues
Answer:	According to the Air King website the rating is: 2470 / 1700 / 1360. I open 3-4 windows part way and set it to exhaust (instead of intake) and it very effectively cools approximately 1400 sq. ft. overnight.

User questions & answers

Question:	Can the exhaust fan be installed on the wall as a ventilation fan for the whole room
Answer:	Don't know if this is correct but here is the math: The 8.5 M/S air speed (attributed to the fan in the additional images) is pushed via a 12" fan. 8.5 M/Sec = 1673 Ft/min. 12" fan = 28.27 square in = .19 square ft. Therefore, 1673 ft/min x .19 square ft = 328 cubic ft/min.
Question:	Does the exhaust fan work with 110v
Answer:	It is not noisy, it makes noise like any pedestal fan
Question:	Does this come with a power cord
Answer:	Very good
Question:	What's the dimension of the 10inches fan
