    As with most automobiles these days, it's all about how accessible the part is, and if you have the tools to get in there. Excepts for simple repairs, I leave it to the experts these days. I used to really enjoy working on my own stuff.

    Anyway, if it's easy to get to, I can see no pitfalls, other than crud getting into the system. Just be careful.

    I have not worked on automotive AC in quite awhile, but usually they used a flowrater as a metering device, not a TXV. Either way it is not hot hard to change but required a vacuum pump to evacuate the system before recharging.

    I would say it is a process. Replace the valve and dryer. A good evacuation of all air and moisture from the system is very important, following with the proper refrigerant weighed in. Be carefull with the sensing bulb and cap tube on the valve if it has one.

    I would just replace the valve myself to save some $$$. Mechanic thinks it's plugged up or something. He can evacuate the system and refill...etc.

    Honestly if it isn't hard it might just be better to let him do it.
