Leak Testing Services in Lake City & Gainesville, FL

Testing your air ducts for leaks is a wise move for any home or business owner. Studies have shown that 75 % of U.S. homes experience air leakage issues that range between 20-40 % of the total airflow. Industry analysts estimate 90 % of buildings in North America experience some level of leakage from their air ducts.

Those statistics suggest it is likely that you are losing conditioned air, as well as the money spent creating it, through leaks in your air vents. How can you be sure? The answer is to allow the certified technicians from Glenn I. Jones Home Services to test for duct leaks in the HVAC system at your home or office in the Lake City and Gainesville, Florida area.

Our crews will use a duct leakage tester, which is a diagnostic tool designed to measure the airtightness of your ductwork. A duct leakage tester consists of a calibrated fan for measuring the air-flow rate and a pressure-sensing device to measure the pressure created by the fan flow. The combination of pressure and fan-flow measurements is used to determine the ductwork's airtightness.

The airtightness of ductwork is useful knowledge when trying to improve the energy efficiency of your HVAC system.

Methods for Conducting a Duct Leakage Test

  • Using only a blower door (not recommended)
  • Using a blower door and pressure pan (for diagnostic purposes only)
  • Using a duct leakage tester and blower door together (most common method)
  • Using a flow hood

Standard Pressure for Leak Testing

For duct leakage testing, the standard pressure used is 25 Pascals, which is close to the operating pressure of a typical duct system. When we measure 120 cubic feet per minute of duct leakage at 25 Pascals (written as 120 cfm25), that number is a pretty good estimate of how much air leaks out of your duct system while it is operating. To minimize those leaks, Glenn I. Jones offers both standard duct sealing and Aeroseal duct sealing options for our customers.

Understanding the Two Types of Air Leaks

There are two types of air leaks, benign and malignant. Malignant leaks are the ones that need immediate attention. They send conditioned air into unconditioned spaces in your building or they suck unconditioned air into the system. Either way, a malignant air leak is a problem. It will either raise your utility bill or decrease the indoor air quality of your home or business.

Benign leaks are the ones that occur inside the conditioned space. They don’t exact an energy penalty.

Each type of leak requires a different test. Because the malignant leaks occur in ducts that are outside the conditioned space, we must perform an “outside leakage test.” The other test is called the “total leakage test.”
