That should include replacing the capacitor and contactor every 5-10 years.
I believe that a true drop in replacement for R410a has not been developed because of greed. There is a lot more profit in replacing the system as opposed to replacing the refrigerant.
I plan on keeping my system as long as possible as I think it is probable that new compatible refrigerant will eventually become available.
