The heat exhaust hose on our air conditioners is 59 inches in length. We’ve designed it this way as longer hoses don't deposit as much hot air outside and some hot air can stay in your home. To keep your environment as cool as possible, we do not recommend using a longer hose and don’t sell one.
If you would like to purchase and fit your own heat exhaust hose, please contact our customer care team for the diameter of the hose.
