Duct Leakage testing has turned into a necessity in numerous locales and all around USA. The reason for duct leakage testing is to assess how well a home’s duct system can hold air. The thought behind it is that the more air that leaks out of the duct system, the more potential energy loss can happen.
We are here to perform the duct leakage test for your home or building ductwork. A pressure test is performed on the duct system to decide whether the duct system is fulfilling the guidelines of the current building codes.
The requirements were set up by the 2015 IECC energy codes.
Ducts have to be pressure tested to test air leakage by:
Rough-In Test: Total leakage estimated with a pressure differential of 0.1-inch w.g. (25 Pa) across the system, including manufacturer’s air controller installed in place – All registers taped or sealed.
Post-Construction Test: Total leakage estimated with a pressure differential of 0.1-inch w.g. (25 Pa) across the whole system, including producer’s air controller enclosed in place – All registers taped or in any case sealed.
Exemption: Duct air leakage test not needed where ducts and air regulators are inside the building’s thermal envelope.
Ducts are utilized for providing conditioned air to the building. These duct systems are comprised of metal sheets, flexible duct tubing, or duct tube. There are many joints and links in the duct systems that are potential sources of leakages. Leaky ducts might affect the heating or cooling as well as the HVAC system effectiveness in your building.
Inadequately fixed ducts might meddle with the activities of your systems, decrease the quality of air and cause high utility bills. Little leaks that stay invisible can turn out to be enormous and expensive issues in the future. Leaky ducts can increase the heating and cooling bills, lessen the overall performance of the hardware, and may bring down indoor air quality by adding contaminated air to the system. Leaks in air duct systems are viewed as a significant source of wastage of energy. Studies demonstrate that 25% of the home energy loss can be accounted for by duct leakage. Appropriate installation and fixing of the ductwork can lessen leakages and increase energy efficiency as well.

To begin with, you need to decide whether a duct leakage test is required. Duct testing is required when parts of the HVAC system are outside of the conditioned envelope. This incorporates areas like unconditioned lofts, carports, and unfinished plumbing spaces. On the off chance that any supply or return duct is outside, conditioned lines or air units are around there, by IECC 2015 code, a duct leakage test is required. On the off chance that an unfinished plumbing space is covered, no test is required.
A duct leakage test (duct testing) can be performed at rough-in before drywalling or post-development. In both of these cases, the prerequisites are very similar. The system should accomplish a leakage rate of under 4 CFM (cubic feet each moment) per 100 square feet of the home.
Leaking HVAC ducts can affect your utility bills, and they can likewise put pressure on your whole HVAC system. At the point when air ducts are firmly fixed, the conditioned air can successfully go to the right place, guaranteeing that you stay comfortable in your home. At the point when these ducts are loose or broken, your system needs to work twice as hard to condition the air in your house.
Despite the fact that it might take some time, you will most likely start to see that your ducts are defective during the hottest days of summer and late-summer months, as your airflow won’t function as successfully. After you hire duct leakage testing with HERS Test Rater, we will start by doing a full assessment of your present heating and ventilating system. Utilizing a flex tube and other gadgets, we will check how much air is getting away both inside and outside of your house.
Additionally called an “entire home infiltration test,” duct leakage testing is a safe and secure approach to increase your energy proficiency and keep your home cool. When we find any leaks, we will make a speedy move to seal them and secure your system.
Testing the ducts requires fixing all of the openings of a duct system. This incorporates checking all of the supply and return registers. We do this by utilizing big HVAC tape to cover and seal the openings. This process can be time-taking as we attempt to make the ideal seal. Our fan is then fixed to the air controller.
The fan is running to decompress the duct system, too – 25 pascals. The measure of air traveling through our fan is then estimated. The number produced under 25 pascals of pressure is known as CFM@25. This CFM number is the number utilized in the estimation.
Subsequent to performing many tests, we have created a list to help you effectively pass our test.
