If both heater hoses get hot, there may be a problem with the air dampers in the ductwork.

If both heater hoses do not get hot, the core may be clogged or the water pump is not circulating well.

Brown chunks is not good.
They did not do a good flush if it is still in there.
Is the temopture gauge coming up to normal?
Is it full of coolant?
If you have a strong smell inside do not drive without window down for venlation.
Coolant fumes inside car can be bad on your health.

You need to find a good repair shop and get it checked out.

Tips on findingf a good repair shop.
Check around Ask around
Word of mouth.
Family friends coworkers neighbors business people and delivery people.
Mailmen and parcel delivery people get around and notice a lot of stuff.
Even a good parts house knows what shops are good and not good.
Chamber of commerce and better business bureau and city hall.
If you find a good referral to a repair shop go look them over and talk to them.
Look for a clean looking busy place with nice people running it.
Ask a few questions and ask about their qualifications and training.
Not all places have trained tech/mechanics.
If they do not find a place that does.
Even all dealers do not have all trained techs/mechanics.

Good Luck and let us know how it goes.
