Direct Answer: What Poor Indoor Air Quality Usually Means
Poor Indoor Air Quality usually means the HVAC system needs diagnosis at the thermostat, airflow path, electrical controls, refrigerant circuit, ignition sequence or duct system. Homeowners commonly notice dusty house or allergies worse indoors. Common causes include dirty filters, duct contamination, no ventilation. If the symptom is mild and the home is still comfortable, basic filter and thermostat checks can help before scheduling diagnosis.

- Check that the thermostat is set to the intended mode and temperature.
- Replace a visibly dirty filter and confirm supply and return vents are open.
- Write down any error codes, sounds, smells, water, ice or breaker behavior.
- Avoid temporary fixes that hide the symptom before the source is documented.
- Schedule diagnosis if the symptom returns after basic filter and thermostat checks.
