Stop Duct Leakage with Duct System Pressurization and Sealing
![]() ![]() ![]() ![]() | Duct Pressurization Testing and Sealing for Energy Savings, Health & ComfortEPA tests have shown an average of 30-35% air loss in HVAC duct systems.Duct Leakage and Air LossThe only exacting method of measuring the leakage in a duct system is to pressure test it. This is done by connecting a computerized pressure testing device to the duct system. A large 12" diameter duct and fan are connected to a return inlet of the duct system and the remaining supply and return grilles are taped off. Then the test can begin. The fan pressurizes the entire duct system to a very low pressure and special sensors/probes send the pressure reading to a small hand held computer. Calculating Air Loss from Duct SystemThis small computer automatically calculates the amount of air loss from your duct system in CFM, (or cubic feet per minute). Based on the size or tonnage of your equipment, we can tell what percentage of air loss, if any, from your duct system to unconditioned space. The higher the percentage of air loss, the higher the cost to heat and cool your home. Even if you have new high efficiency equipment this loss negates that efficiency. Leaky ducts not only dramatically increase your gas and electric bill, they lower the capacity of the system by not putting all that conditioned air into your home or office but instead blowing into your attic. The typical home in America has duct leakage of about 25% to 35%.This means a 5 ton capacity system may be trying to cool the home with only 3 tons of air conditioning. This causes the Air Conditioner to work improperly, run forever without cooling the space, never getting to the desired temperature on the hottest days, and adds a high cost to operate. This duct leakage has an even more sinister side effect. It allows dust, dirt, and other attic contaminants into your home for you to breathe. But help is available. Sealing a Duct SystemBy sealing the duct leaks or replacing the duct with new modern high efficiency type the leakage can be brought down to below 5%. This can lower your heating & cooling costs by up to 30%, allowing your system to cool the home on even the hottest days while circulating only clean, dust free, healthier air into the space. Find Out How Much Air Loss is StoppedWant to know how much air loss we have stopped? That's easy and exact by re-testing the system after repairs have been made. In fact, on a new equipment installation this work is a California state requirement, also requiring an independent certified third party rater to test and verify the reduction in air loss. That's how important it is and is the ultimate in quality control to insure an efficient duct system installation. Please contact us to set up a survey, inspection and pressure test of your system.
