Static Pressure Testing And Mapping Demonstration Youtube Pressure If the ductwork of an hvac system is not designed, installed, and maintained properly, your home may start to have problems in comfort, humidity control, dus. Watch building forensics expert corbett lunsford demonstrate total external static pressure testing and pressure drop testing for a residential furnace and air conditioner. learn to diagnose pressure problems in supply and return ductwork, filters, evaporator coils, and duct sections in just a few m. Center the test ports for neat appearance. stay away from any coils, cap tubes, condensate pans, or circuit boards to avoid damage. in other words, always look before you drill. an hvac technician taking a static pressure measurement. step 2: drill test ports using a 3 8′ drill bit with a metal piercing tip. Utility manometers are your typical standard service manometers; they are designed to measure pressure in inches of water column (“wc, “h2o, or inwc). inches of water column are smaller units of measure than psi, and they’re ideal for static pressure and gas pressure. some utility manometers have one port, and others are dual port manometers.

Commercial testing can have a range of 0 to 10”, although a 0” to 5” scale will do for most systems. you’ll want a minimum accuracy of ±3% with a minimum resolution of .01” water column. larger scale manometers lack the accuracy you need. be sure the manometer has at least two pressure ports, one positive and one negative. Step three: turn the system on with the fan set to deliver the highest required airflow. this is cooling mode for most of the country. step four: measure and record the pressures at these two test sites. step five: add the two pressures together to find the operating total external static pressure of the system.
