$450 to replace home AC capacitor

To the point, our home AC unit was found to have a capacitor out of range by 10%. The quote for $450 to replace it seems on the high side, even considering we live in a city where everything is expensive (Austin). Considering that our AC is working, would it make sense to wait a few months to start getting quotes from other companies? My thought is that we're in the hottest week of the Summer and we could be encountering surge pricing.
