Product review (1 stars): DON'T BUY AIR KING
I would not purchase anything from Air King after my current experience.  We had a smoke damage in our kitchen and the kitchen fan which we had for 15 years with NO problem, needed to be replaced.  Our contractor purchased and installed this fan--my only requirement after reading the horrors of kitchen fans was that it have a FIVE year warranty.  Ten months after install, we were cooking and heard a funny noise and the lights and fan quit working.  The company sent me a few fuse and switches that I changed myself.  When that didn't work, they sent a new fan.  Fast forward two years.  The exact same thing happens--the noise, the new fuse and switch replacements that do nothing.  Only they have NOT respected their warranty and tell me this model with the knobs (instead of rocker switches) only has a one year warranty.  Here is what the insert says verbatim:
All products manufactured by Air King Limited are warranted for one year from the date of purchase against defects in workmanship and/or material. In addition, all ventilating/exhaust fans, heaters, combination fan lights and/or heaters, and range hoods are guaranteed for five years from the date of purchase against defects in workmanship and/or material.
If you don't mind a product that dies within the year and is replaceable...great, buy Air King.  However, if you want something more than disposable appliance and a company that backs it's products, DON'T buy Air King!
