Pressure Sealing Systems in Chicago
Commercial Duct Sealing & Duct Leak Repair
Every business owner wants to save as much as possible on fuel costs. What measures have you taken to cut back on energy usage? If you have yet to perform duct pressure testing to detect leaks, put this item at the top of your priority list.
Inadequately sealed ducts waste energy, contribute to poor indoor air quality, and encourage mold and mildew growth when condensation forms as cold and warm air meet. Duct pressure testing is necessary to detect the severity and location of ductwork leaks. Once revealed, it’s possible to close up these leaks with a pressure sealing system.
Murphy & Miller seals and insulates ductwork in commercial and industrial buildings in the Chicago area. If you’re interested in increasing your facility’s energy efficiency, please call us today at 1-312-427-8900 or contact us online.
Inspecting the HVAC System for Duct Leaks & Energy Loss
The first step is to find out if your ductwork is leaking. Unless you have had improvements made in the past, it’s likely that your ducts leak 20 to 30 percent or more of the air passing through them. This amounts to tremendous energy waste for your business! An inspection and duct pressure test reveal a great deal about what’s happening behind the scenes.
To perform a duct pressure test, we first close off the return and supply registers with vent caps or grill masks. Then, we set up a calibrated fan at one of the building’s central return vents to pressurize or depressurize the ductwork. A manometer hooked up to the fan measures the difference in pressure between the fan and an established reference point on the supply end of the air ducts. We use this reading to calculate the percentage of air leaking from the ductwork.
Installing a Ductwork Pressure Sealing System
The leakage points of a typical duct system are located around trunk line seams, supply line entrances, joints between trunk and supply lines, and connection points surrounding the air handler. These and other leaks can be closed up with HVAC gaskets and seals.
While the primary purpose of ductwork pressure sealing is to save energy, it also tackles other common ductwork problems. Here are some of the additional benefits you can expect:
- Improve indoor air quality by blocking the introduction of insulation particles and fumes from unconditioned spaces of the building.
- Discourage mold and mildew growth by preventing condensation inside the ductwork.
- Reduce vibration transmission to limit the noise of operating the HVAC system.
- Retain an air-tight seal despite the natural expansion and contraction of metal ductwork.
