Basically what is being said by AJ ( not to put words in his mouth) is let your ear be your guide.
I agree and will add that in New Age often several bars get pedal ( you just hold it down), there may even be a notation to hold the pedal to the end and the end may be four lines away yet. When I play that and if there are seriously clashing chords ( your ear will pick it out) then I let off the pedal and re-apply. Notation in New Age isn't as strict as in Classical music, I think you should feel free to compromise what's written to a fair degree in New Age.. I play a fair amount of both ( classical and new age), they make a nice compliment to one another. In classical it may be more critical as to amount of pedal applied as well ( how deep you push in to the damper pedal), where in New Age it's generally a heavy push on the pedal. New age likes the overtones as long as there is reasonable harmony. It's part of that genre of music it seems. I liken it to holographic viewing or perhaps etherial realism .
If you are playing on a digital piano you can really lay into the pedal on those. An acoustic is different there, you might want to back off a bit and be more aware of the breaks. An acoustic piano can get pretty noisy with overtones much faster than digital it seems.
New Age is fun to play though, it's like going on vacation in the summertime compared with a long winters work. Some pieces have a nice quality sound to them others do not, so I pick carefully !
