Replacing air handler - How to fit when form factors are slightly different??
The best way to make your transition is have a sheet metal shop build it. If your system is over head I would definatly reccomend the use of a canvas joint. The canvas joint's job is to stop vibration of the unit from resinating into duct work and the living space. Keep in mind a good sheet metal shop is not going to be cheap, you are paying for craftsmanship. The cheap way out but not by any means a permanent solution is duct board, its easy, its fast, and it doens't last very long. As for sealing the base to the air handler, the best solution for that is a high quality silicone, it will stay pliable for years and will generally adhere well to the metal surfaces. Hope some of this made sense for you.
