in pcl5 the axial bonds suffer repulsion from the equatorial bonds so they become long and weak but in pf5 the axial and equatorial bonds are of nearly equal length because the repulsion between the bonds tries to make axial bonds longer but fluorine being most electronegative makes the P-F bond shorter as a result axial bonds become nearly equal to equatorial bonds.

i disagree with the answers posted already as far as i know in case of PF5 axial F atoms exchange their positions with equitorial F atoms which is not the case for PCl5 hence in PCl5 due to different repulsions for axial and equitorial Cl atoms their bond length changes while for PF5 as axial and equitorial F atoms exchange their positions frequently so their bond length remains same, similar to the concept of resonance in which we have hybrid structure with all bond lengths same.
