Description (2000 words):
Welcome to MK Technical Solutions, your go-to channel for all things HVAC and technical solutions! In this comprehensive video, we tackle one of the most common issues faced in air handling units (AHUs): supply air duct sweating. If you’ve noticed moisture or water dripping from your AHU supply ducts, this video will guide you through the causes, solutions, and prevention techniques to keep your system functioning optimally.

What is Duct Sweating?
Duct sweating, also known as condensation on ductwork, occurs when the air around your ducts is warmer and more humid than the air inside the ducts. This temperature difference causes water droplets to form on the outside of the ducts, which can lead to water damage, mold growth, and reduced efficiency of your HVAC system.
---
Why Does Duct Sweating Happen?
Several factors can cause your AHU supply air ducts to sweat. Let’s go over the most common reasons for this issue:
1. Temperature Differential:
The main cause of sweating is the temperature difference between the cool air inside the duct and the warm, humid air outside. The larger the temperature gap, the more condensation will form on the duct’s surface.
2. High Humidity Levels:
High humidity in the space where the ductwork is located can also contribute to condensation. When moisture-laden air comes into contact with the cool surface of the ducts, condensation occurs.
3. Poor Duct Insulation:
Insufficient or poor-quality insulation on the ducts can lead to sweating. Without proper insulation, warm air can easily reach the cool ducts, accelerating the condensation process.
4. Leaky Ducts:
Ducts that are not properly sealed allow cold air to escape, increasing the likelihood of condensation on their outer surface.
5. Poor Ventilation:
Inadequate ventilation around the ducts can trap warm, humid air, increasing the chances of condensation.
6. Oversized HVAC Systems:
If your HVAC system is too large for the space it serves, it may cool the area too quickly without adequately removing moisture, leaving the ductwork more susceptible to sweating.

Signs of Duct Sweating:
Visible water droplets on the outside of the ducts.
Water stains or damage around the ductwork.
Development of mold or mildew near the duct area.
Increased humidity in the space served by the AHU.
Musty odors, which are often caused by moisture or mold.
---
Problems Caused by Duct Sweating:
If left unchecked, duct sweating can lead to several problems, including:
Water Damage: Moisture can accumulate on ceilings, walls, or floors near the ductwork, causing water damage over time.
Mold Growth: The damp environment created by condensation is an ideal breeding ground for mold and mildew, which can negatively impact indoor air quality.
Reduced System Efficiency: When condensation builds up, your HVAC system may work harder to maintain temperature and humidity levels, leading to higher energy consumption and operational costs.
Health Risks: Mold growth can pose serious health risks, especially for individuals with allergies or respiratory issues.

Solutions to Prevent AHU Supply Air Duct Sweating:
1. Improve Duct Insulation:
The most effective solution to stop duct sweating is to insulate the ducts properly. High-quality insulation materials like fiberglass or foam insulation can reduce the likelihood of condensation by minimizing the temperature differential between the duct surface and the surrounding air.
Consider adding vapor barriers to prevent moisture from coming into contact with the ducts. Vapor barriers block the warm, humid air from reaching the cool surface of the ducts, thereby preventing condensation.
2. Seal Duct Leaks:
Air leaks in your ductwork can allow cool air to escape, further contributing to condensation. Sealing these leaks with mastic sealant or duct tape can help maintain proper airflow and reduce the temperature difference around the ducts.
Be sure to inspect the ductwork regularly for any cracks or loose connections, and seal them as soon as
