If its the external hoses - probably not costly of you can do the work yourself. Replace parts and refill the system with coolant, which can be a pain.

If its the heater core, then it could be really expensive if you have to take out the dash to get to the core or its hoses. There may be a back door way to avoid disassembling the dash. Look for some threads where people to reseal re-foam the control flaps without removing the dash unit. These threads usually mention black pieces coming out the vents
