im tall so i need a longer t-tube for my scooter.
First, you need a heating/AC contractor to do an inspection of your houseThis inspection notes all windows and doors in the home plus the direction it facesThese units are not sized by the square footage of the house, but by heat and cooling loss factors determined at the time of the inspectionSince you can't lose what you don't have, go with the heating/cooling system first.
Well, I had The same problem,I switched my friend For his Pro-Model T-TubeBut if you are unable to do that then you can get one from a Po-Go stickBut might have to cut it becuase it could be too long Goto Home Depot- or Lowes and buy some Aluminum pipe and make oneTheres videos on youtube on how to make your own.
