Heating coil should be a heater core. You will still have heat even if your core is leaking.
A car can easily servive without heater core. All you have to do is by pass it. This job is easy to do yourself. The only problem you encounter will be no heat.

The only thing in question: two different shops found different problems.
Try to find one more and see what they will tell you.

How did they find that the core is leaking from the starters?
