Our expert says:
It's a good idea to sort out the mold issue in any case, but it might not be the causative factor (or not the only one).
Other possible indoor environmental causes to consider include: dust and dustmites, animal dander, cockroaches, and I'm sure I don't need to mention cigarette smoke.
Outdoor airway irritants can sometimes enter a residence, and these include nearby industrial or traffic air pollutants and pollen.

Keeping your home clean, uncluttered, dust-free and well ventilated, and allowing sunlight in where possible, are good basic measures to reduce indoor pollution.
Keep in mind that commercial cleaning products (and air fresheners) themselves may be contributing to irritation that makes you cough. Always try to use small amounts of these, maintain good ventilation when cleaning and consider switching or supplementing to non-toxic alternatives.
