My heater is quite loud I dont know about you guys but its very loud and doesnt work that well for all that noise. Also when i press the direction of the heat it kinda makes a buzzing sound for a minute. My vents also rattle on speeds 2 and 3 but not 1 or 4 . When i do both directions up / down like almost no heat comes out Weird huh ? Im thinking somethings clogged or something.
