Contactor and Capacitor

Is it impractical to replace the contactor and capacitor on my 8-year old Comfortmaker condensing unit if it's still running?

The unit is operating fine but the contacts on the contactor look burned and pitted.

I'm going to be out of town most of the summer; just trying to avoid a failure to happen while I'm gone.

Neither one is very expensive. There's no reason why you couldn't replace them both, even though they are currently working. However, if you do replace them, I would suggest that you hang onto the capacitor as a spare. If it goes bad over a weekend, it might be nice to have something you can install temporarily to keep the system running until you can get a replacement. Also, it seems like some of the newer capacitors don't last as long as the older ones did. My 24 year old Bryant A/C still has the original capacitors and contactor.
