奥兰多这个修理价格合理吗？

5年新的TH，平时没有啥修理，今天PM发来这个，也就是运送佛利昂的管道出问题。价格赶上半个空调了！

The lineset that carries freon to the unit is broken and needs to be replaced.  The cost is $2400.  They have to run a new lineset from the outside unit to the air handler.  They usually go through the attic to do this. The unit was down 6 lbs of freon which means it pretty much all leaked out of the system.

远程，也不好亲自去多找几家问价。PM是个大公司，估计懒得给多问几家。
