How can I play a clean sounding F chord on guitar?

I've actually been playing for 3 years now, but I can't play an F chord well. The problem is not the first four strings but the high E and B strings sound muted because my finger isn't strong enough to press down. If I really focus on the chord when I'm not playing a song then I would get a sound from all strings, but I usually do quick chord changes that are tricky like from C to F and I can't get a full sound from the chord. This mostly happens with my acoustic guitar, I can do an F chord on my electric guitar like nothing. How can I make my F chords better?
