Usually the only time I open the system is after another compressor dies. I use my AC a lot. A compressor last about 90,000 miles. The orifice tube is always replaced. For less than a buck it is a no brainer. Most of the time there is some gunk on the old one. The accumulator is replaced only if the compressor is replaced.
I did find this filter that I may order and have on hand for the next system purge.

Hopefully the current compressor will last another few years.
The suggestion I like the most is to tie the fan to the brake lights. Now I need to figure out how to tie the brake light switch into a relay that will signal the fan to come on if the compressor is running.
So if the AC compressor is running and the brakes are pressed the fan runs. If either the compressor is not on, or the brakes are not on the fan does not run.
This is my current setup (no pun intended)
