Your attic doesn't have to be a forgotten energy drain. The Quietcool AFR SMT ES-2.0 turns it into an active part of your home's climate system. Whether you're fighting summer heat buildup or winter moisture, this smart attic fan automatically adjusts to keep your attic temperature and humidity in check. Using just 24.6 watts on low—less than a standard light bulb—it moves up to 1950 CFM, reducing strain on your AC and lowering your electric bill.
But the real benefit is the peace of mind that comes from a smarter home. The Smart App Control lets you set schedules, adjust speeds, and monitor conditions from anywhere. You get alerts if the fan detects a problem, so you can address issues before they escalate. With its built-in thermostat and humidistat, the fan runs only when needed, extending its lifespan and saving energy. The 20-foot power cord gives you flexibility during installation, and the brushless ECM motor runs whisper-quiet—no more noisy attic fans waking you up at night.
Install it yourself or have a pro do it; either way, the one-piece stamped steel hood and UV-resistant paint ensure it handles the elements. The fire safety shut-off adds an extra layer of protection. This isn't just a fan—it's a smart home upgrade that pays for itself over time.
