Hey Darren, the Coleman-Mach Underbunk # CM82RR has a 2 year warranty that covers it from date of purchase for manufacturer defects. When in auto mode the fan of this does not run all the time. But if you select high or low it will run all the time. What are you looking to install this in?

My current unit is a Dreiha HB9000. Do you have install instructions for the Coleman under bunk unit. Curious about how close the holes are for the floor cutouts compared to the unit that I have. Is there any extended warranty options for purchase with this unit?

@DarrenS We don't have a set of their instructions linked on our site yet but if you Google Coleman Underbunk AC Instructions you'll be able to find a link to them. I do not believe we offer any extended warranty options for this or anything else we carry.
