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。
