Air conditioning is essential in modern office buildings, ensuring a comfortable work environment year-round. But for many, prolonged exposure to AC can cause throat irritation, dry airways, and persistent coughing. If you’ve noticed an uptick in coughing complaints among building occupants, your HVAC system could be playing a role. Here’s how to address the problem and create a healthier indoor environment.
Why AC Can Trigger Coughing
Prior to identifying remedies, it is crucial to grasp the underlying causes. “AC-induced coughing” typically stems from multiple contributing elements:
Dry Air: AC units tend to reduce indoor humidity. Low humidity dries out the mucous membranes in the throat and nose, making them more prone to irritation.
Dust and Allergen Circulation: Poor filtration or infrequent maintenance can circulate dust, mold spores, and other irritants.
Cold Air Exposure: Constant exposure to cold airflow, especially directed at the face or neck, can provoke reflex coughing.
Microbial Growth: Damp areas in the HVAC system, especially coils and ducts, can harbor bacteria and fungi, which are then dispersed through the air.
Recognizing these root causes helps facility managers and office operators tackle the issue effectively.
Tip 1: Regulate Indoor Humidity Levels
Maintaining optimal indoor humidity—ideally between 40–60%—can significantly reduce coughing and other respiratory symptoms. If your AC system excessively dehumidifies the air:
Install Commercial Humidifiers: Integrated humidification systems balance moisture levels across entire floors or zones.
Monitor Humidity in Real Time: Use smart sensors to track and adjust humidity based on occupancy and climate conditions.
Upgrade to HVAC Systems with Built-in Humidity Control: Some advanced models offer precise moisture regulation as part of their core functionality.
Tip 2: Upgrade Filtration and Air Purification
Basic filters aren’t always enough to capture the fine particles that cause irritation. Enhance your air quality by:
Using High-Efficiency Filters: MERV 13 or higher filters can trap allergens, fine dust, and microbes more effectively.
Implementing UV-C Technology: UV-C lights integrated into the HVAC system deactivate harmful microorganisms such as bacteria, viruses, and mold spores before they circulate through the air.
Adding Portable Air Purifiers in High-Traffic Areas: For quick relief in trouble zones, HEPA-equipped purifiers offer a direct solution.
Regular maintenance is also key. Filters should be inspected monthly and replaced as recommended by the manufacturer.
Tip 3: Avoid Direct Airflow Exposure
Coughing often increases when occupants sit directly beneath vents or in the path of cold airflow. To prevent this:
Adjust Vent Placement and Angle: Redirect vents to distribute air more evenly throughout the space.
Use Diffusers and Deflectors: These accessories soften airflow and reduce its intensity.
Rotate Seating Arrangements: Periodically review and adjust desk placement to minimize direct exposure.
Comfortable airflow isn’t just about temperature—it’s about direction and consistency.
Tip 4: Schedule Professional Duct Cleaning
Over time, ducts accumulate dust, debris, and biological contaminants. Without proper control, these can lead to indoor air quality issues. Regular duct cleaning:
Reduces Airborne Irritants
Improves HVAC Efficiency
Extends System Lifespan
Partner with certified HVAC professionals who follow NADCA standards to ensure thorough and safe cleaning.
Tip 5: Choose the Right HVAC Partner
