A Step-by-Step Guide to Cleaning Your Air Handling Unit.

Cleaning your air handling unit (AHU) is essential for maintaining efficient and long-lasting HVAC systems, ensuring optimal indoor air quality and performance. Here, we'll take you through the AHU cleaning process.

Safety Precautions

Before starting, prioritize safety, turn off AHU power, wear necessary personal protective gear (like gloves, safety glasses, and a dust mask), and ensure proper grounding to prevent electrical accidents.

Disconnect Power Sources

As a safety measure, disconnect the power supply to the AHU. It prevents accidental activation during cleaning and protects you from electrical hazards. Depending on your system, this may involve switching off the circuit breaker or shutting down the unit directly.

Access the AHU

To clean your AHU, you need access to its interior components. Open the access doors or panels as per the manufacturer's instructions. Typically, latches or screws secure these doors. Once inside, take note of the layout of the components and their condition.

Remove Debris

Start by clearing out any obvious debris from the AHU. To efficiently gather dust, dirt, and loose particles, use a hoover with a HEPA filter. Pay close attention to the blower assembly, filters, and coils. Make sure to cover all of the accessible locations.

Clean Coils and Fins

Maintain the efficiency of your AHU's heat exchange and AC by cleaning its coils and fins. Use a coil cleaner or a water-detergent mix. Employ a soft brush or fin comb to clear stubborn debris.

Check Filters

Inspect the air filters, and if they are reusable, clean them according to the manufacturer's guidelines. If your filters are disposable, replace them with new ones. Clean filters ensure that the air passing through the AHU is free from contaminants.

Clean Drains and Pans

Drains and condensate pans in the AHU can become clogged, leading to moisture buildup and potential mold growth. To avoid obstructions and guarantee appropriate drainage, clean these parts. If you find mold, use a mold cleaner to eliminate it.

Check Belts and Pulleys

If your AHU uses belts and pulleys to drive the blower, check their condition. Replace worn or damaged belts and ensure pulleys are Properly aligned. Properly functioning belts and pulleys are essential for efficient air circulation.

Inspect Insulation

Inspect the insulation within the AHU for damage or mold growth. Damaged insulation can result in energy loss and decreased efficiency. Replace any damaged sections and clean any mold-infested areas.

Verify Control Settings

Before closing the access doors, ensure that you correctly configure all control settings. Check the thermostat settings, safety interlocks, and any other control mechanisms to guarantee proper system operation.

Final Inspection and Testing

After completing the cleaning and maintenance tasks, perform a final inspection of the AHU. Verify that all components are in their correct positions, all electrical connections are secure and that there are no loose items inside. Reconnect the power supply and perform a test run to ensure the AHU operates smoothly.

Regular Maintenance

Cleaning your AHU is an essential part of regular HVAC maintenance. To keep your system in peak condition, create a maintenance schedule that includes routine cleaning, filter replacements, and professional inspections.
