Hi, I just installed my first window air conditioner, GE AMG0LJ. The
window frame is metal and the AC installation
kit is for a wood window frame. does anybody sell AC installation kits
for metal window frames .

BTW, the GE AMG0LJ 6,000BTU is very quite and high efficiency

How about some clarification. In the subject line, you say "Storm Window
Frame" but now you say it is a metal window.

Where I live the storm window sits outside the regular double hung window.
Sometimes the bottom of the storm frame is higher than the sill inside. You
just cut a piece of wood the proper thickness to raise it up equal or
slightly above the storm frame. Cut the wood to length and lay it between
the two windows. Use a 1 x 3 or a 2 x 4 or whatever you need.

If you are talking metal frame inside windows, different story. If it is a
typical double hung, you drill a hole in the frame and use a sheet metal
screw to hold in on top of the AC expander frame.
