Brief Answer:
You should definitely consult a pulmonologist.

Detailed Answer:

Hi,

In my opinion, you should definitely consult a pulmonologist.
You are having chronic cough and you are a heavy smoker.
So we need to rule out bronchitis and lung infection for your symptoms.

So consult pulmonologist and get done a clinical examination of the respiratory system, chest x-ray and PFT (Pulmonary Function Test).
A chest x-ray is needed to rule out lung infection.

PFT is a must for the diagnosis of bronchitis.

Please quit smoking as soon as possible.

Hope I have solved your query.
