Any northeasterners with this fan? Will it be letting cold air into the attic during colder months?

You may want to add a thermostat control so that it will not turn on during the colder months.

Yes, this fan will be letting in air all of the time. If you have access inside, and you can reach it, you can shut it off for the winter, and stuff some insulation up into it. But, unfinished attics are meant to have airflow all year long, for proper ventilation, even in cold weather. If your insulation is weak, why not increase that amount in your attic. If you get this fan, it will even work on cloudy days, maybe, not as fast as sunny ones, but it keeps the attic air moving, during the daylight hours. At night, air still flows through the fan , just like a vent openig. I hope this will help ypu. Yes, this fan will be letting in air all of the time.

I am in Wisconsin. These fans are excellent. The bug/animal infiltration prevention screen is well installed and made of some very durable hardware cloth. Most attics are meant to be open to the outside all year round. They are meant to keep the air space between the house and roof vented. That is the purpose of an attic. The biggest concern you should have with an attic is whether or not you are getting proper ventilation. For those of us in the cold climates, condensation and humidity in winter in the attic can be a concern. I have found that these attic fans work better even in passive mode during the winter much better than a static vent. I always get the thermostat unit so the fan only runs when the temp in the attic is 70F or higher. I have three of these fans, and have had them for many years. They are excellent.

Mine has not had any problems, we live in eastern NC which has high humidity, very good fan.

Can't offer a comparison to other fans, but there must be quieter ones out there because this one does make a lot of noise. You can clearly hear it from both inside the house and outside. It is significantly louder than the 20 yr. old fan it replaced, but I have a feeling it also has a higher rated capacity, because it does seem to move a lot of air. The only encouragement I can offer is that if you set the thermostat high enough, you could get it to turn itself off in the evening. Don't know what temp. that might be in your area: mine is set at about 105. Good luck.

Hello! The fan blows a strong amount of air but will only be as cool as your AC setting allows. Hope this information is helpful!

We live in Michigan & bought our fan a year ago. It stayed outside, uncovered but next to the house throughout the worst winter ever and it stil works just fine. My only regret is not to have bought 2 fans.... Good luck!

I don't see why it would not be OK. depending on the temperature in the attic? it is like any other Hub it does generate some heat but as long as you have some ventilation it should be OK. there are cooling slots on the side of the unit for ventilation but this may cause a problem with dust and dirt in the attic? I have mine in a closet and you can not feel any heat from it at all. Good luck

This is pretty quiet but we don't think we would put in Living area, it is a great attic or garage fan.

We love it James. Although we put ours in the garage attic, it seems quiet enough to put in a living area. All I know is that it's lowered the temp in the garage by about 20+ degrees!

This a very powerful strong blowing fan! Just remember ur not adding cold blowing air, it will be just circurlating the hot air. Hope this well helpful :)

Customer service said it's okay - "The unit will operate well in the environment you have described. The air being removed from the bathroom will be considerably cooler than the attic which will reduce the fan temperature as it passes through the fan."Regardless, you should install attic ventilation at the same time. 130 and higher is too much and damaging to your roof.

This particular fan is mainly sold, designed, & intended for crawl space use. Although it's possible that it might work in an attic,there is a better alternative. Both Lowe's & I believe that Home Depot might carry exactly what is specifically designed for attic use. Lowe's carries both gable mounted & through the roof fans that have both a thermostat & a humidistat for removing heat or humidity from the attic. Normally the thermostat is set somewhere between 90 & 100 degrees & the humidistat is set somewhere between 60 & 70 percent. Both adjustments can be changed to suit the user & particular conditions in your attic. I have a through the roof model in one house & a gable mounted fan in the other & both do a fantastic job! The gable mounted fan is a little easier to install. I think either one of these fans would-be a better choice & do a better job than a crawl space fan! I hope this information has been helpful to you.

If you are worried about cold air going come from the attic fan opening it does not seem to be an issue. Heat rises. If anything warm air would escape to the attic if the louvers were open for some reason. May 5, I live in Michigan and have not turned on my air conditioning other then to make sure it works.Warm days still have cool nights so we set the fan on 2 hours, crack the windows. Makes for some good sleepin'.

I'll try and break the tie. Its an electric fan mounted in a heavy aluminum base (I dont think the pictures do them justice, these things are pretty big) that requires sunlight to shine on one side in order to work. IMO it doesnt really make any more noise than any other fan that moves a similar amount of air, my fridge is way louder. You would wind up with a 12" or so circular hole in the roof that the fan is fastened to the outside of; you would need to put some sort of grill over the inside of it to keep fingers out of the spinning blades. It probably would not amputate a finger but could easily make a nasty cut. Plus its not the prettiest thing on earth to look at. You will also need a substantial source of air into the room otherwise you will be creating a suction. If the two rooms are connected you could swap the wires on the motor of one of them (would require some electronics skilz) and have one suck and the other blow and get a draft through the area. You will also need to provide a way to close it off completely in winter to avoid letting cold in. You could put a switch on it in conjunction with the closing mechanism so it doesnt run when closed. Additionally roof vents (powered or not) are not as insect proof as window screens, the openings are bigger. Might be a consideration for inhabited areas.

I had another fan installed without attic access. However, I have recently learned that the original unit was not ducted correctly, to the outside as i was told, but it exhausts to the attic soffit area, which I'm told will cause frost this winter, and probably mildew and mold, not at all what is wished! So, in that case, yes, attic access will be necessary, but if you already have a fan in the ceiling, and you have a qualified handyman who can do the job, I could be wrong, but it seems that attic access might not be needed, if you are wishing only to switch out your old unit, and to put this one in.

Well, it will circulate the same air in the room. At night when the outside air is a bit cooler, and you put the fan so it sucks air into the room, it will cool it down gradually.

I don't remember hearing a fan. But I have the router in my garage in a cabinet. The temperature says 80 degrees F and the switch has been just fine. During the winter is got to about 20 degrees. Performs great for me!

Not really. Does not impact my house in that way. If anything the fan just helps air circulation in the attic.
