New Duct Sealant Improves HVAC Systems

Airtek Indoor Air Solutions frequently works with mechanical contractors on large projects to ensure that HVAC leaks are sealed properly. During a major air duct cleaning project a few years ago at the University of California, San Diego, Airtek worked closely with a mechanical contractor as well as a sub-contractor who trailed behind to re-seal the ducts after the cleaning was completed. It became evident that these services go hand-in-hand.

In an effort to offer a more complete service to our customers, Airtek became educated in sealants and their effects on duct systems. In addition to the wide-range of services involving HVAC systems, Airtek now provides customers with this duct sealant service.

Benefits of Duct Sealant

In the average residence, 20-30% of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. The more CSM loss there is, the more work the system has to do in order to perform. As a result, it is difficult to maintain a consistent air temperature and people are paying higher utility/energy bills.

When this occurs in commercial buildings, these problems are intensified. In addition, leaky duct systems can create condensation, which creates moisture and eventually mold. Resealing the ducts can make homes and buildings more comfortable, energy efficient, and safer.  In addition, there can be dramatically improved indoor air quality when systems are purged of long, often unnoticed particulate.

RS-100 is an innovative sealant that is changing the way that ducts are sealed. It is a water-based sealant designed to be internally sprayed in ventilation and air conditioning duct systems.  It is fiber-free, non-flammable, and mold resistant. It allows flexibility so that when there are system vibrations, the seal does not crack and leak. It is engineered to seal joints and seems from the inside of the ducts.

Application

The sealant is applied robotically using a special attachment called a Nikro, which creates a cone shaped spray so that it can shoot into round or square ducts. The cone allows the sealant to go around the perimeter, not just straight ahead, to ensure full coverage and thorough sealing. When joints and seems are painted with RS-100 from the inside, the seams are protected and leaks are prevented.

In an ongoing effort to improve customer satisfaction, Airtek offers both duct cleaning and duct sealing to our customers. The use of RS-100 has proven to be the most effective sealant with long-term results. Recently, Airtek completed projects at Scripps Research and UCSD using RS-100, and have been able to increase efficiency and safety of their systems.

How Commercial Duct Cleaning can Prevent Liabilities and Save Money

Although most air duct systems in buildings cannot be seen with the naked eye, they are an integral part of a structure and employees’ well being. More often than not, employers overlook the need for commercial duct cleaning, and only when they have a problem or complaint do they look into the option for improving their air quality needs. Choosing to maintain your system with a routine commercial duct cleaning process can lead to better employee productivity as well as profitability for the entire company.

Could it be Time to Clean Your Clogged Dryer Vents?

The redundant household chore of doing laundry has been assimilated into our everyday routine. It has developed into one of those day-to-day tasks that become second nature – we do it without even thinking: piles of clothes, washing machine, detergent, start button… dryer, fabric softener, start button… fold, put away, complete. If you pause to ponder a little deeper into the process, however, you will find there are a copious amount of factors that need to be taken more seriously and require more than what seems to be “programmed” into our schedules. The greatest danger: clogged dryer vents. Continue reading

AQMD-Compliance

What to Know About AQMD Compliance

The Federal Clean Air Act sets standards for maximum pollutant levels. Each state has an implementation plan to reach those levels, with different Air Quality Management Districts (AQMD) responsible for pollution levels within a clearly defined geographic area. AQMDs are responsible for the enforcement of control regulations and implementation of creative methods to help cut pollution. Understanding, adhering to, and demonstrating your knowledge of AQMD compliance is critical for all parties involved in your business, from the community your business operates in, to the owners and employees, to your customers. Here’s a look at the ins and outs of AQMD compliance:

 

Public Hearings Allow Input on Proposed Laws

Individuals and corporations concerned about the effect a proposed law will have on their particular situation have the opportunity to comment at a series of public workshops and hearings. Workshops are less formal occasions where the public has a greater opportunity to voice opposition or support of a proposed law. A final public hearing precedes a vote by the AQMD board.

 

Classes Provide Clear Understanding of Compliance Requirements

AQMDs provide compliance classes so company environmental officers can have a complete understanding of how certain laws affect their industry. The classes cover all applicable rules and permit requirements. An AQMD speaker’s bureau also provides experts who will come to your company or civic group and address pre-arranged topics of concern. AQMD’s public information center is a great place to stay on top of proposed new laws and industry trends that will help your business stay ahead of the environmental regulation curve.

 

Follow the Permitting Process

The two most common permits issued by the AQMD are the Permit to Operate (PO) and Permit to Construct (PC). As their names imply, you must get a PC before either installing new equipment or moving existing equipment to a new location. A PO is necessary before you can turn the new equipment on. Application forms and instructions for all permits are available on the AQMD website. You must submit all applicable fees at the time you file the permit for approval.

 

Hearing Board has Authority to Grant Variances

If you can show good reason as to why your company should not have to adhere to a particular regulation, the AQMD Hearing Board has the power to grant a variance. The board is made up of an independent group of industry professionals appointed by AQMD. Along with considering variances, the hearing board also considers abatement orders, appeals from companies denied a permit, and third party appeals. Although the hearing board can grant a variance, it cannot modify rules, review violation notices, or grant a variance from compliance with a public nuisance law.

 

Online Tools Assist in Reporting Process

Some AQMDs have web-based tools that cut down the paperwork involved in reporting emissions, applying for permits and calculating fees. The Facility Information Detail (FIND) tool for the South Coast AQMD provides links to public information about regulated facilities within the district’s boundaries. The Flare Emission Notification System helps refineries and similar facilities report when an event is expected to exceed a particular emission threshold.

 

Advisory Group Membership Provides Insider Knowledge

One of the best ways to stay informed on the workings of a local AQMD is to join one of the many advisory groups that play a major role in the implementation of new rules. The Air Quality Management Plan Advisory Group consists of members from all walks of life, including large and small businesses and government agencies. Attending AQMD public hearings and regular meetings is the best way to become known and receive an appointment to a working group.
