Quietcool AFG SMT ES-3.0 Smart Attic Fan for Gable Vents: Smart App Control with thermostat and humidistat
You just want your attic to stop baking your home into an oven. The Quietcool AFG SMT ES-3.0 Smart Attic Fan mounts into a gable vent and pulls hot, humid air out before it soaks into your insulation. Unlike a whole-house fan, this stays in the attic where it belongs, making it ideal for homes without ridge vents or in hot, humid climates.
What sets this apart is the built-in thermostat and humidistat working with the smart app. You set your temperature and humidity thresholds, then the fan runs only when needed—no more guessing or climbing into the attic. The three-speed ECM motor uses as little as 22 watts on low, so it can run all day for pennies. The included 20ft power cord and plug-and-play design mean you don't need an electrician. Anti-vibration pads keep it quiet, so you forget it's there. Your AC will run less, and your home will feel more comfortable without you having to think about it.
