Overlooked Ductwork Impact on Homes

3 HVAC Issues Associated with Ductwork

Homeowners and contractors often overlook the impact of ductwork on heating, ventilation, and air conditioning (HVAC) issues in homes. People seem to always think the problem has to do with the HVAC equipment (e.g. furnace, AC unit). However, the equipment can be operating fine, and you can still have common HVAC issues such as dust/allergies, hot/cold spots, and high utility bills.
Issue #1: Dust and Allergies Associated with Bad Ductwork

Correctional facility project with Aeroseal

Correctional Facility Energy Savings Achieves $7000/yr with Duct Sealing

When one of the industry’s most respected facility services providers was asked to make energy-efficient upgrades to a correctional facility in Pennsylvania, it had two key issues in mind. First, the services provider knew that the facility would be occupied during renovation, so limiting disruptions and health risks to the occupants was essential. Secondly, working as an ESCO, the company also knew it had to deliver on promised energy savings or face paying the difference out of its own […]


Hilton in Saudi Arabia Saves Energy, Meets Codes with Duct Sealing

When it opens to the public in 2018, the Hilton Riyadh in Saudi Arabia will be one of the top 10 Hilton Hotel properties in the world. Construction began on the massive luxury hotel and residence project back in 2012. The two-building complex has 866 guest rooms as well as four restaurants, including a roof garden cafeteria, a business center, health club with an indoor swimming pool and a 1,750 seat ballroom. The total built up area for the […]


7 Construction Codes Support Tighter Air Ducts, More Rigorous Testing

Earlier this year, we published a blog post about various construction codes being updated with tighter duct leakage standards or more rigorous duct testing. We coined this phenomena, “2018: The Year of the Duct,” to encompass all the codes involved including ASHRAE, Uniform Mechanical Code (UMC), International Energy Conservation Code (IECC), and many regional authorities such as the California Title 24.
More recently, ACHR News echoed 2018 being the “Year of the Duct” highlighting the following codes with increased focus […]

What is Duct Sealing?

What is Duct Sealing? (As Seen at U.S. DOE Energy Exchange)

Not to be confused with ducks or seals (the animal), duct sealing is a way to improve the heating, ventilation, and air conditioning (HVAC) in homes and buildings. It’s a process of sealing visible and invisible air leaks in air duct systems.
Why Duct Sealing Matters
Short answer: Duct sealing makes homes and buildings more comfortable, saves energy, and improves indoor air quality (IAQ).

VA Hospital Meets Codes with Aeroseal Duct Sealing

Just months after opening the doors to its new Veterans House, the VA medical center of Indianapolis, Indiana discovered that the building’s Energy Recovery Ventilation (ERV) system wasn’t working properly. The diagnosis: intake and exhaust ductwork running throughout the building and through the ERV were full of leaks, making it impossible to balance and adjust airflow. Strict government standards require a leakage rate of 10% or less. Pretesting showed a leakage rate that exceeded 45% in some areas. Faced […]

two ways to save energy in school

Two Ways Schools Can Slash HVAC Energy Costs

Heating, ventilation and air conditioning accounts for about 37% of electricity use in U.S. educational facilities, according to U.S. Energy Information Administration data. That makes HVAC systems a prime target when it comes to trying to save money and energy. Two proven ways to accomplish this is through HVAC optimization and duct sealing. Upgrading systems to run at peak efficiency can save thousands of dollars or more on annual energy bills.
HVAC Optimization
Optimization involves finding a way to deliver the […]

ASHRAE Publishes New Standard for Commercial Building Energy Audits

The newly released ASHRAE Standard 211-2018 for Commercial Building Energy Audits establishes consistent practices for conducting and reporting energy audits for commercial buildings. It also defines the procedures required to perform ASHRAE Level 1, 2, and 3 energy audits, provides a common scope of work for those audit levels for use by building owners and others, and establishes standardized industry practices and minimum reporting requirements for results.
The standard was approved by ASHRAE on April 30, 2018. It was also […]
