1. Pressure Testing: This is the most common method and involves pressurizing the ductwork system and measuring the amount of air leakage. The process typically involves the following steps: Commercial Air Conditioner Repair Emergency Air Conditioner Repair Near Me Hvac Furnace Repair 24 7 Ac Repair

   • Preparation: The HVAC system is turned off, and all registers and vents are sealed.
   • Equipment Setup: A specialized fan, known as a "blower door" for ducts, is connected to the ductwork system. This fan is used to either pressurize or depressurize the duct system.
   • Pressurization/Depressurization: The fan is used to pressurize or depressurize the ductwork system to a specific test pressure, typically 25 Pascals (Pa).
   • Measurement: The amount of air leakage is measured using a flow meter. The flow meter measures the volume of air required to maintain the test pressure.
   • Calculation: The air leakage rate is calculated based on the measured airflow and the surface area of the ductwork system. The result is typically expressed in CFM25 (cubic feet per minute at 25 Pa) or L/s at 75 Pa (liters per second at 75 Pascals).

2. Visual Inspection: This method involves a visual inspection of the ductwork system to identify leaks. While less precise than pressure testing, visual inspection can be a useful preliminary step to identify obvious leaks. The inspection may involve: Commercial Ac Companies Ac Emergency Repair Near Me Ac Heater Repair 24 7 Air Conditioning Repair

   • Visual Examination: A thorough visual inspection of the ductwork system, looking for signs of damage, gaps, cracks, or loose connections.
   • Smoke Testing: In some cases, smoke testing can be used to pinpoint the location of leaks. Smoke is introduced into the ductwork, and the areas where smoke escapes are identified as leaks.
   • Infrared Imaging: Infrared cameras can be used to detect thermal anomalies that may indicate air leaks.
