Why Clean Air Ducts? Answer: Because They Get Dirty!

In addition to normal accumulations of dust and dirt found in all homes with air ducts, there are several other factors that can increase the need for regular HVAC system cleaning:

Pets
• Occupants with allergies or asthma
• Cigarette or cigar smoke
• Water contamination or damage to the home or HVAC system
• Home renovation or remodeling projects

Some occupants are more sensitive to these contaminants than others. Allergy and asthma sufferers, as well as young children and the elderly tend to be more susceptible to the types of poor indoor air quality that air duct cleaning can help address.

Top Benefits of HVAC Cleaning

NADCA’s rule of thumb for consumers is that “if your air ducts look dirty, they probably are,” and that dirty HVAC systems should be inspected by a reputable, certified HVAC professional. Below are some other reasons homeowners choose to have their air ducts cleaned.

Indoor Air Quality

Indoor air quality is one concern that homeowners have when they decide to investigate air duct cleaning. Your heating and cooling system is the lungs of your home. The system takes air in and breathes air out.

Through normal occupation in a home, we generate a great deal of contaminants and air pollutants, such as dander, dust, and chemicals. These contaminants are pulled into the HVAC system and re-circulated 5 to 7 times per day, on average. Over time, this re-circulation causes a build-up of contaminants in the duct work.

While dirty ducts don’t necessarily mean unhealthy air in your home, school or workplace, they may be contributing to larger health issues or harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or some environmental allergies.

Energy Savings

According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating or cooling a home is wasted. Contaminants in the heating and cooling system cause it to work harder and shorten the life of your system. Although filters are used, the heating and cooling system still gets dirty through normal use.

When an HVAC system is clean, it doesn’t have to work as hard to maintain the temperature you desire. As a result, less energy is used, leading to improved cost-effectiveness.

Aeroseal Sparks Trend in NY High-Rise Retrofitting

Sealing from the inside allows engineers to fix ventilation in older buildings where access is limited, resulting in lower energy costs and improved IAQ.

Like most older buildings throughout the United States, the Carlyle Towers in Caldwell, New Jersey suffered from poor ventilation. Leaks in the duct work prevented the huge rooftop fans from effectively drawing air out of the many bathrooms, hallways and living spaces within the 55-year-old multi-family apartment building. Limited access to the duct work made manual duct sealing methods impossible without severe demolition to the building’s walls and ceilings.

Several years ago, the engineers at Steven Winters Associates decided to tackle the problem using a new technology developed by the U.S. Department of Energy that seals leaks from the inside of the duct work. The success of that project has resulted in the technology’s use to solve similar ventilation issues in thousands of apartments throughout the New York City area alone.

In Brief

  • Building: Carlyle Towers apartment building
  • Location: West Caldwell, New Jersey
  • Property Owners: Legow Management
  • Engineering Contractor: Steven Winters Assoc.
  • Goal: Improve ventilation, lower energy costs, improve indoor air quality and HVAC comfort
  • Before Aeroseal: 250 CFM average leakage/shaft
  • After Aeroseal: 15 CFM average leakage/shaft
  • Results: 90% reduction in leakage; $26,000/year energy savings; even room-to-room comfort. 

It took engineers just 4 weeks to Aeroseal all 25 of the building’s individual ventilation shafts. With the leaks sealed and the pressure within the shafts balanced, contractors were able to replace the 25 300-watt roof exhaust fans with 140-watt units. The fan optimization alone resulted in an annual energy savings of $7,000. In addition, the improved HVAC efficiency afforded by the leak-free ductwork decreased gas use by approximately 30% – from an average of 57,000 therms (EC)/year to 41,000 therms (EC)/year for an additional savings of approximately $19,000 annually.

Since the completion of the Carlyle Towers retrofit project, hundreds of similar New York-area multi-family apartments with central ventilation have been similarly retrofitted for higher energy performance.

Testimonials

Soon after the retrofit was completed, we heard from tenants who thanked the building manager for fixing the heat. While we didn’t touch the heating system per se, by sealing the shaft leaks and automating the damper adjustments, the furnace was noticeably more efficient and effective” (David Legow, President, Legow Management).

Aeroseal sealed on average 90% of the duct leakage, and that had a significant impact on the ability to properly balance ventilation and reduced the use of both gas and electricity” (Marc Zuluaga, Vice President, Steven Winters Associates).

Overview of the Cleaning Process

NADCA members are accustomed to handling a variety of projects for commercial and industrial buildings. NADCA’s presence in the commercial HVAC industry is growing steadily as education about our members’ services grows. It is becoming increasingly common for project proposals to specify the presence of an ASCS certified individual on a commercial job.

When hiring a NADCA member, an optimal level of performance should be expected. Technicians are required to adhere to the industry’s standards and guidelines, and inform the client of any obstacles that may prevent doing so. NADCA members are able to able to answer most questions about a particular project, including safety issues and are able to provide proof that the job has been done correctly.  

Through clear, concise communications, air duct cleaning contractors can provide their clients with a better understanding of the work to be undertaken and demonstrate that the project will be well managed. Clients should also clearly define the scope of work they desire and are encouraged to utilize NADCA’s General Specifications for the Cleaning and Restoration of Commercial Heating, Ventilating and Air Conditioning Systems.

HVAC system cleaning projects require a game plan. Project length can vary from a few hours to six months or more. The size and scope of the project are the two key elements that will have an impact on the length of time necessary for completion. The entire duct cleaning project will run smoothest when an in-depth review is first conducted to determine the expectations and desired outcome for both the customer and duct cleaning company. 

  • During cleaning, the entire HVAC system is placed under continuous negative pressure — with a vacuum — to prevent the spread of contaminants.
  • Continuous negative pressure allows very fine particles to be removed from the system as they become airborne, ensuring that these particles are not released into the living space when the system is turned on after cleaning.
  • This negative pressure also serves to extract the loosened contaminants, which are collected and removed from your home.

Often, HVAC system components collect significant amounts of debris and particulate during construction activities within a building. NADCA recommends that newly installed HVAC systems or HVAC systems undergoing renovation be verified clean and protected before the system is permitted to operate.

Dust and Allergies in Your Home

Pollen, dust mites, mold, animal dander and other contaminates are common allergy triggers.  There is not much you can do about pollen or dust outside of your home but when you’re indoors nothing is worse than having that month long runny nose during the fall or mold allergies in the spring.

When you have leaky ductwork in your home you can expect with 100% certainty that these common contaminates are in there with you.

 

Dust and allergies in your home may be caused by Duct Leaks

Do you notice substantial dust in your home?

Ductwork is typically run through attics, crawlspaces, basements or even behind walls.  When you have leaks in your ductwork, they will suck air from these spaces into your living areas.

By sealing your ductwork you can limit the entrance points of your home that allow dust, pollen, or mold into your home and insure a much cleaner & healthier environment.

Homeowners who seal their ductwork with Aeroseal experience less dust and allergies in their homes!
