iLIVING HYBRID Ready Smart Thermostat Solar Roof Attic Exhaust Fan, 14", 40-Watt, 1150 CFM, Cools up to 2900 Sq.Ft. Coverage Area, Black

I installed the variable speed controller and 14” blade exhaust fan in my attic at the beginning of Dec, which was a much nicer installation as the attic temperature was much cooler than normal as the outside temperature was much lower. Once I had mounted the fan high up on an outside wall that already had a (shutter) vent. I only needed to have a 120vAC outlet to plug in the fan controller. Overall I found the insulation easy and was very pleased with this product quality which has worked flawlessly since, very pleased I purchased this fan.Since the fan was installed I have noticed a big difference in the attic temperature and have saved money on my utility bill because my AC unit is not running as much as it was before the fan was installed.The fan is not too loud either, quieter than I originally thought it would be when the fan is running. However, I did decide to mount the fan on rubber (shock absorber) anti-vibration pads (purchased separately) to help with any vibration, noise from the surrounding wood framing where the fan was mounted.Normally I keep my AC at 72 deg F, so by exhausting the very hot attic air (Max 150 degrees F) that’s in my attic, which transfers heat through the ceiling into living spaces below. My AC doesn't need to come on as early in the day and shuts down sooner in the evening.Overall I am glad I made this decision to install this fan in my attic and very happy with this purchase.

The best fan I could have bought for my attic, I recommend it 100%

Living on the top floor of an old house has always meant dealing with extreme heat in the summer. The space heats up so quickly, and even though we added extra insulation when we moved in, it didn’t completely resolve the issue. The top floor would still become unbearably hot, making it difficult to enjoy the space. After researching solutions, I decided to try this solar-powered attic fan, and I’m so glad I did.Installation was straightforward, and I was pleasantly surprised by how well it works. The fan has improved ventilation in the attic space between the ceiling and roof rafters, which was previously a major source of heat buildup. Since the fan started running, our top floor has stayed significantly cooler, even on the hottest days. The fan’s solar power is a great bonus since it runs efficiently without increasing our energy costs.The difference has been night and day. The temperature on the top floor is much more comfortable now, and the fan works quietly without being intrusive. It has made a huge difference in maintaining a livable temperature throughout the summer, and I’m really happy with the investment. If you're dealing with similar heat issues in an old house or a poorly ventilated attic, this fan is definitely worth considering—it’s a practical and effective solution.

Helps reduce the utility bills

I Put this fan out in my 12×8 green house this spring it works great.The thermostat is right on target with a digital thermometer I have in the green house.

Fit perfectly

The old one was very noisy also broke down stopped working within a year. This new one is very nice and quiet.What our family likes most is that it can adjust the temperature and turn it on and off automatically.

During a complete re-roof job, I had the licensed roofer install two of these fans. One of them leaked from the joint where the upper portion of the assembly joins the base plate. Water damage to my kitchen ceiling resulted (second photo). I called back my roofer, who traced the leak to that seam. He caulked it (first photo) and since then we've had several inches of rain and no more leaks.I've had an ongoing convo with Iliving about this. First, they tried to blame it on "improper installation". When I pointed out that the water intrusion was through the seam in the unit, not from the interface with the roof, they said the leak happened because the seam wasn't caulked. I pointed out to them that the installation manual says nothing about this seam needing to be caulked. They replied that the damage done to my ceiling is not covered under the warranty. They refuse to take any responsibility for anything. These fans work well but if you have an issue, don't expect any help from Iliving.
