Purchased system and within a week the drive board failed. HVAC direct will not return you phone calls and they will make excuses after excuse why they can't get a board. Finally I had to call INGRAMS and they actually sell parts for the units they sell. I have never seen such a thing, get your $#*! together hvac direct and get tech support that knows what they are talking about. Your tech support guys are absolutely clueless. Stay away from Mr cool and the stupid parts chasing game they play. I should've known. AT THE END OF THE DAY I PURCHASED ANOTHER UNIT JUST TO TAKE THE PARTS FROM IT DUE TO NON EXISTENT PARTS WITH MR COOL.
