User questions & answers

Question:	Can the cord go the other way so you can plug it in outside
Answer:	The cord comes out the middle in a small gap and can either direction. This is so you can reverse the fan. So either way you have the fan installed (intake or outtake). The cord can come inside or outside if you wish.
Question:	Would this fit a 34 inch wide window
Answer:	No! I also have a 34 inch window and I built a wood side to make it fit perfectly in the window. The fan works great!
Question:	Will this fan fit a 24 inch wide window
Answer:	no. the fan is almost 25" wide.
Question:	Do you like this item
Answer:	So-so window fan. Misleading to fraud listing! Since you must click for sellers, Amazon staff likely compiled the listing. It isn't 9" blade. 9" ONLY IF YOU COUNT THE CENTER PIECE. 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 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.

User questions & answers

Question:	How high is the fan? the product dimension say 13.8, the amazon description says 12. I want to try and fit is a 12x24 vent in the ceiling
Answer:	exact size is 12" (without the stand feet) by 23.5 (without the side extensions, which you can remove)
Question:	Can the fans run independently of each other? For instance you can run one on low, while the other is off
Answer:	No. I think I've tried all operations. The fans run at same speed, but can run intake, exhaust, or one each.
Question:	How wide do the extenders go? I have a kitchen window that is about 42 inches wide and would like to secure it in to blow outward
Answer:	it sits in my standard sized window, but that is only about 36" at most. I've put it in longer windows, & yes, it does leave a gap.. it pretty much stops at 36-37" max
Question:	what is depth of fan. And does it allow one side for intake while the other blowing air simultaneously
Answer:	Yes the fan has three settings. 1)Both blow in, 2) Both blow out, 3)and One blows in, the other blows outAs for size, it is about 4 inches wide at the grills. It is designed to sit in the channel of the window, and then you close the window down on top of it. On the top, the plastic is molded in such a way as to "grab" the window in a channel. When in place, the side panels go out to the sides, and the window comes down on top of it. the side panels are a bid difficult to pull out, and close the latches back, but it is something you only do once when you put the fan in the window.
