But thank goodness I did or possibly could’ve been a fire or electrocution! Quieter than I expected. Smaller fan sizes usually have to make more noise to do the job of a larger fan.A few non electricals may think they can install but become confused with one black, one white and one yellow/green stripe wires inside. Notice in the picture I added, I realized this after reading a few on reviews on here And sure enough mine was one! All around a fair heater for the money took the chill off a two car garage in about 20 minutes, the one thing that got me was how it passed any kind of Quality control?
