Scubapro's warranty would give you free parts replacement, but you would always pay for labor anyway. I'm not sure an annual servicing of a BC would entail replacing any parts, if everything looked good--unless of course you were using an Air2 rather than a standard power inflator (if there's a kit for the standard power inflator, I have never seen it--but there might be). Even if you're not the original owner, SOME Scubapro dealers will not charge you for parts on servicings AFTER the first nonwarranty servicing, as long as you bring the gear back for its annual within a year. Always good to have your regs serviced annually, esp if you're diving the NE--and it would be great if all technicians and all servicings were reliable and thorough, but they are not. Make sure your technician has a good track record, esp servicing Scubapro gear.
