Celebrate National HVAC Technicians Day with Preferred Hood & Duct

air duct cleaningLet’s show some appreciation for the HVAC technicians that help us stay cool through the summer heat by celebrating National HVAC Tech Day, recognized on June 22, 2017.

Many of us are already cranking our central air conditioners to stay cool through this year’s already sweltering summer heat. The luxury of being able to stay in the comfort of our air-conditioned homes wasn’t always around. Heating and cooling systems came into existence during the 1900s, but continue to improve. HVAC technicians help to clean, maintain, repair and replace HVAC systems to improve air quality, energy efficiency and more.

Summer would be a lot less comfortable without them!  Continue reading “Celebrate National HVAC Technicians Day with Preferred Hood & Duct”

Diagnose Rusty Air Ducts in CT with Regular Air Duct Inspections

Closeup of a rusted air duct.Air ducts don’t often make the news (they work best neither seen nor heard), but in a story last month out of Long Island, ducts unfortunately took center stage. Northport V.A. Medical Center in Northport, New York was forced to close all of its operating rooms last May, delaying the surgeries of over 100 veterans, when sand-sized black rust particles were found to be spitting from the aging hospital’s air ducts. The possibility of rust getting into a patient’s open wound during surgery was simply too risky to keep the ORs open, reported doctors.

Coverage of the story rightfully focused on the impact is had on the health and wellbeing of dozens of veterans, but there’s also a lesson to be learned regarding the importance of regular duct inspections and maintenance, especially when rust comes into play.

Rusted Air Ducts: What Causes Them, Why You Don’t Want Them

The primary cause of rust in air ducts is the same as that of rust anywhere else: excess moisture. Depending on where your ducts are located, excess moisture can become a problem due to leaking pipes, a leaky home foundation, leaks in your roof or insulation, and other problems. When your metal ducts come into contact with any of these sources for a prolonged period of time, rust develops. This eventually causes holes to form. (Mold is also a potential problem with excessive moisture.)

Situations like the one at the V.A. hospital cited above are likely a worst case scenario when it comes to rust in air ducts, but any rust has the potential to lead to adverse effects on air quality. In addition, any holes caused by rust are certain to reduce the efficiency of your HVAC systems, leading to increased energy bills and poor performance.

Rust in air ducts can also be indicative of rust or damage to other HVAC equipment, like heat exchangers, boiler tanks, and heating oil tanks, each of which could pose a serious threat to health, safety, and quality of life.

Regular Inspections Can Diagnose Rust in Ducts Before It’s Too Late

A qualified air duct and HVAC inspector will be able to find new rust in ducts, diagnose the problem, and take care of it before vents start spewing black rust. Better yet, inspections could reveal leaks or high-moisture conditions that lead to rust before any even forms.

If rust in air ducts is caught early enough, it can be removed, and the affected ductwork wrapped or insulated in moisture blocking material. This will prevent rust moving forward. Ducts might also need to be patched, repaired, or even outright replaced. If this is the case, the long-term savings will be well worth it.

While we can’t say for sure if the unfortunate situation at the Northport V.A. could have been avoided with a more diligent air duct inspection schedule, we’re more than certain that it remains the best practice for homes and commercial buildings everywhere.

ACCA’s Updated HVAC System Cleanliness Standard Approved by ANSI

air duct cleaningAs with any other industry, HVAC cleaning relies on a strict set of standards. Set by the Air Conditioning Contractors of America, these guidelines for the HVAC cleaning industry are called Restoring the Cleanliness of HVAC Systems standard, or the ACCA 6 QR – 2015.

New guidelines were recently approved by the American National Standards institute (ANSI) for the first time since 2007. The new guidelines have been clarified for language and streamlined for efficiency, with updated references and citations.

According to the updated ANSI/ACCA 6 QR – 2015 standards, the minimum procedures and practices for HVAC cleaning are as follows:

  • Determine when airside surfaces should be cleaned, and when they require repair or replacement;
  • Clean the airside surfaces within HVAC systems;
  • Control the spread of contaminants, which may be released as a result of the HVAC cleaning process;
  • Verify the cleanliness of HVAC systems.

More detailed standards are laid out for different areas of the HVAC industry, including refrigeration system maintenance, system installation, installation verification, residential maintenance, and restoration. More information about ACCA guidelines can be found on their website here.

The ACCA’s Quality Standards are detailed instructions for design, installation, maintenance, and repair, and have been adopted across the board by utilities, government agencies, manufacturers, and HVAC technicians across the country. If you’re looking for HAVC cleaning services, be sure to ask if the company if they’re familiar and compliant with the ACCA’s standards. If they’re not, it’s time to find someone more reputable.
