This week a repairman replaced the capcitator on my heatpump.He did not have a 55 that he needed so he connected a 50 with a 5(not sure what these numbers mean) and assured me it would be fine.Should I be concerned?My gut tells me I should have told him to drive back to the shop and get a 55.

This has been done many times to save time and money (your money). As long as it is properly installed there should be no problems.
