My dog coughs, sneezes, spits brown mucus. Vet says AC. Is it serious?

Pet's info: Dog | Labrador Retriever | Male | neutered | 5 years and 8 months old | 88 lbs

My dog has been coughing/sneezing/reversal coughing for the last 6 months. His veterinarian said it's caused by the AC and that it's nothing to worry about. He spits too much mucosity and mucus are brown (we live in the desert). What can it be?

I doubt the AC is to blame. Cough can be caused by an infection, heart problem or lung condition, it is important to first know the cause before treating it as treatment is different from condition to another. you should request your vet to perform an xray in order to try and find out what is causing this.
