Just a curiosity question. Seems like every year and a half
to two years I have to have the capacitor replaced on the
outside part of my central AC. Is this normal? I mean, do
capacitors normally wear out this often?

No. My current two machines are over 5 years old and run every day during the
summer with no problems. Likewise in a previous house - 8 years with no problem.
