ENERGY WASTE IN
BUILDINGS TODAY
ASHRAE estimates most commercial buildings experience 10-25% air duct leakage. This requires HVAC systems to work more than necessary to keep buildings at comfortable temperatures.
A recent study from the Building Commissioning Association quantified duct leakage as a $2.9B problem.
BUILDINGS ARE BLOWING
ENERGY DOLLARS AWAY!
Increased Fan Energy
Poor Air Quality
Ongoing Operating Costs
The more air that leaks out of your ducts, the harder your fans have to push to reach the desired space. Duct leakage leads to excess ventilation loads, which in turn drastically increases your energy costs.
Leaks in the return duct allow airborne allergens, viruses, and bacteria to be sucked into the duct system. These contaminants are then spread throughout the facility, compromising air quality for other occupants.
Leaky ductwork is the primary cause of ineffective building exhaust, causing problems with uneven and uncomfortable temperatures that can lead to higher energy bills, and added maintenance costs.
INTRODUCING OUR PROVEN
DUCT SEALING PROGRAM
We combine energy advisory services, experienced technicians and award-winning technologies to eliminate duct leakage and unnecessary energy waste.
The Duct Sealing Program provides a cost-effective,
non-disruptive solution to eliminate energy loss, maximize HVAC efficiencies and reduce carbon footprint.
INCREASE VENTILATION. REDUCE ENERGY. OFFSET CARBON.
The Duct Sealing Program allows facilities to significantly increase air volume and exchange rates
by rehabilitating ductwork infrastructure and sealing leaky ducts.
As a result, buildings can significantly improve indoor air quality, eliminate unnecessary energy waste and reduce carbon emissions - without the need for costly mechanical upgrades.

Airtight Ducts. Airtight Returns.
Reduce Energy Costs
Duct Sealing addresses multiple sources of energy waste. For example, by reducing leaks 15%, fan requirements drop by 40% or more. This saves thousands of dollars every month. Duct Sealing increases HVAC fan efficiency and eliminates excess ventilation load to reduce energy costs. It is a verifiable and guaranteed way to offer energy savings with typical payback in two to five years.
Improve Building Ventilation
Leaky ductwork is the primary cause of ineffective building exhaust. In addition to causing problems with uneven and uncomfortable temperatures, this can lead to higher energy costs, and added maintenance costs.
Improve Indoor Air Quality
Leaks in the return duct allow dust and other contaminants to be sucked into the duct system and spread throughout the facility. And exhaust fans can’t remove contaminated air from the building if there are leaks in the ventilation shaft.
Meet Code & Spec
As duct leakage specifications get tighter and tighter, Duct Sealing is specified as a routine component of commercial projects. Duct Sealing offers consistent results and will take you from hoping to knowing that you’ll meet code requirements – the first time
Seal up to 99% of your ducts in 1/3 of the time and HALF the cost vs. any alternative solution available.
