Keeping in mind that OP is in AZ, the brake fluid should be in a lot better shape, moisture wise, than other, more humid places. Having said that, brake fluid should be changed periodically. For my daily drivers every 3-4 years seems to be working well. How do I know this? Because the brake pedal feel improves only slightly after the flush.
I would go ahead with the brake fluid flush, maybe go to another place if the price seems too high, and see if you notice any improvement in pedal feel/firmness. If no, or very little improvement is felt, I would extend the next flush by a year or two.
