When to Schedule a DOAS Unit Repair / Upgrade
Your Dedicated Outdoor Air System (DOAS) plays a crucial role in maintaining indoor air quality, humidity control, and energy efficiency. Over time, components can wear out or technology may advance—making an upgrade or repair the smart choice. Here are key signs your DOAS system needs attention:
Inconsistent ventilation
If certain areas of your facility feel stale or humid, your DOAS may not be distributing outdoor air effectively—indicating a need for service or recalibration.
Humidity or moisture issues
Excess indoor humidity can lead to mold growth and discomfort. A DOAS upgrade with enhanced dehumidification technology can restore healthy air balance.
Rising energy costs
If energy bills are climbing, your system may be overworking to meet ventilation needs. Upgrading to a high-efficiency DOAS reduces operational costs and energy waste.
Unusual noises or vibrations
Banging or rattling sounds could indicate worn bearings, fan imbalances, or motor issues. Prompt repair prevents costly downtime and extends equipment life.
Outdated or aging equipment
If your DOAS is over 10–15 years old, upgrading to a modern unit can significantly improve airflow control, efficiency, and indoor comfort levels.
Poor indoor air quality
Lingering odors, dust buildup, or occupant complaints may point to a failing filtration or ventilation process—professional DOAS repair can quickly resolve these issues.
