Overall rating: 4.6 / 5 from 17 reviews.
I ordered three of these solar vent fans on August 20th and received them the very next day, on August 21st. We installed them on August 25th, and the difference was noticeable almost immediately. The next day, when I got home around 2:30 p.m., I could instantly feel how much cooler my garage was. What really surprised me was the difference throughout the house. Three of my bedrooms are on the opposite end of the house from the AC unit, and I went into each room to see if I could notice a difference. They felt amazing! I honestly couldn't believe it. My son now sits in his room wrapped up because it's actually that comfortable and cool! As of August 29th, we are extremely happy with this purchase. I was impressed with how quickly the fans made a noticeable difference, and I'm very glad we decided to purchase three of them. So far, they have been worth every penny! Coach D
With a change in roofing color from light gray to Dark Charcoal, it made perfect sense to increase our attic ventilation capacity with the combo 55watt solar/120V electric roof fan & vent. The remote controls work great with 6speed levels & thermostatically controlled operation. We love them both!! Steve&Pat
This fan replace an existing fan in my attic. This fan is a lot quieter than the original. This fan has made a difference and my upstairs is cooler in temp.
With the thermostat setting, just set it and forget it!
Great quality solar fan, panel quick responsive to sunlight and the remote control is an extra bonus for the operation. My guess is if the solar panel ages in the long run, DC power will take on the energy for the remaining working life. Highly recommanded for any homeowner who want to regulate attic temperatures.
Works as it should and good quality!
Nicely built solar fan. The installation is a breeze. Quiet and spinning fast. Especially like the smart temperature control feature. It automatically runs above 77 F and stops when the temperature drops below it. The AC backup is brilliant. The AC powers the fan during hot but cloudy or raining days.
Works really good dual solar and plug in!
Works good and really easy to set up, good power with the solar panel
So far is all good they work nicely
GREAT PRODUCT IT WORKS GREAT
Replaced a fan I’ve had for over 20 years, this was much more powerful and I purchased the dual power model as I live in the greater LA area, hot all day and night , I can hear the fan running if I listen for it, but it’s not an issue at all. I would recommend this brand, they shipped it fast and it was properly boxed, solid cardboard. The attic is definitely cooler and i feel like it’s helped cool the living area also by a couple of degrees, I still need to run my ancient AC but hey , I’m in SoCal so that’s totally expected.
Great item!! Thank you!
Install was easy. Instructions were easy to follow. The dual solar/electric fan i purchased is working exactly as described. Moves air very well.
I think it's pretty good though I find it hard to believe it pushes as much air as advertised. I'll take it on faith that does. It works and went up perfectly.
Our upstairs was getting so hot over the summer. We didn't want to go in our room. My husband had me ordered this fan for him to install. Made a huge difference. Would recommend for anyone with a two story house.
The install for this will be happing this week and will be uploading a photo by the 13th.
