Common HVAC Problems That Worsen Moisture Issues
Humidity problems can often be traced back to maintenance issues or aging equipment. Here are common HVAC-related causes:
- Dirty CoilsDirt and debris block proper heat exchange, limiting your system’s ability to cool and dehumidify air.➤ Have coils professionally cleaned during seasonal maintenance.
- Clogged Air FiltersRestricted airflow reduces efficiency and prevents moisture removal.➤ Replace filters monthly or as recommended—especially during allergy or cooling seasons.
- Low Refrigerant LevelsLow refrigerant means the system can’t cool properly, which also reduces dehumidification.➤ Call a licensed HVAC technician if your system is blowing warm air or running constantly.
- Leaky DuctworkGaps or holes in ductwork can pull humid air from crawlspaces or attics into the system.➤ Sealing ducts can improve both air quality and humidity control.
