Bests & Worsts Reviews from Amazon

Having been a heating & air conditioning contractor, I knew the value of attic exhaust fans: a properly sized fan can keep an attic at least 20 degrees cooler than a gravity-ventilated attic. And if your attic is cooler, your house will stay cooler. The problem is that most 120-volt attic exhaust fans are really noisy. The noise from gable-mounted fans isn't too obnoxious, but the noise from roof-mounted fans can drive you up the wall. (The roof membrane acts as a drum and amplifies both the motor vibrations and the 60-cycle hum.) IN CONTRAST, NATURAL LIGHT'S SOLAR OPERATED DC MOTOR IS SO QUIET, YOU HAVE TO GET RIGHT NEXT TO IT TO EVEN HEAR IT! I'm very impressed with this product. It is well made, it has good installation instructions, it comes with an exceptional warranty, and if you need to talk to the manufacturer for any reason, Natural Light is very responsive. The optional thermostat is worthwhile: it prevents the fan from running on a sunny (but cold) winter day.
