shop to flush AC system

[MRacer]

I have my 96 for over 14 years now and had never flush the AC system. WA weather has been kind and the AC always blow nice cool (not cold) air when needed. Now that I'm permanently moving to CA where the weather is ~100F, I should probably flush the AC system, huh?

Can someone recommend a shop to do the work in either Seattle/Sacramento area?

Thanks for the help.
