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.

Helps reduce the utility bills

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.

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.

It was easy to install. Just make sure you use a roofers caulking. I used M1 it's usually what solar installers use for flashing and attachments.

If you buy this product make sure you install right away and do leak test within the Amazon 30 day return as you won't get your money back if there is manufacturer defect. Mine had crack unnoticeable to naked eye. Leaked when water came in directly on top of unit where top of fan was attached to base (not due to installation). Company blamed it on installation and didn't stand by product or warranty. Amazon return has passed because installation was delayed and no rain for a month. Water test around seal didn't leak. Only leaked when water came on at top.
