Water in Ductwork, NOT TODAY!

Have you heard the following things listed OVER & OVER again in regards to your HVAC unit?

“No one wants any sort of strain on their HVAC unit. Strain that could cause many problems that are an extra cost to you. Such as:

-Higher energy bill
-Frequent maintenance on your HVAC unit
-HVAC replacement

There are many ways to keep your HVAC unit stress free. Below are just a few basic steps you can take to keep your HVAC system stress free. Very easy stuff, and they each only take a few moments of your time.

-Keep vents clear
-Keep those coils clean
-Change out the air filters regularly”

BUT, one thing that goes unmentioned quite often is the ductwork. Of course it would. Out of sight, out of mind, right?

Did you know, ductwork carries the warmth in the winter and holds the cool air in the summer. Without proper ductwork insulation, the temperature of the air being carried could be lost while transferring from the HVAC unit to the vents in your home. Ductwork can also play a major role in your energy bill. Even the Department of Energy claims so.

So, you see how important ductwork is. What if just a little bit of water entered your ductwork from the HVAC system? It’s just a little water. No biggie, right? Actually, YES! Even the smallest water droplet is a huge deal! To name a few, it can cause the following:

-Rust out metal ductwork
-Breeding ground for mold, mildew, and bacteria
-Decrease Indoor Air Quality greatly
-Water damage
-Degradation & De-lamination

Although, water in the ductwork can cause many problems. Your health alone should be enough reason to want to get your ductwork checked out. Exposure to mold can lead to allergies, infections, rashes, even alzheimer’s. The list just goes on and on.

When water gets in the insulation in your ductwork, those water droplets fly through your airstream. These water droplets create a breeding ground for mold & mildew. Water droplets will wreak havoc on the insulation in the ductwork causing degradation & de-lamination. Not only would this be tearing your insulation apart to later be replaced (more bucks from your pocket) but that delaminated insulation would be freely roaming the air in your home (remember you & your family are breathing this).

Why worry about water in your ductwork causing this step ladder of issues when there is a solution?

For the new home-owner, why not be preventative & go ahead and protect yourself?

Ductile is a coating that protects the HVAC ductwork from degradation and insulation de-lamination. Ductile locks down fiberglass particles that would enter the air stream. Hallelujah!
No stress of your insulation breaking down & no worries about your health. Did you hear that, NO STRESS!

What Are You Leaving Behind?

What are you leaving behind in your HVAC system?

HVAC preventative maintenance plans are all about meeting the needs of the HVAC system, so it can perform effectively and efficiently. In doing this, clients save money by keeping their power bills down and extending the life of the air handling unit.

In most instances, maintenance involves: changing air filters, inspecting and adjusting belts and blowers, cleaning coils and condensate drip pans, checking thermostats, and making sure economizer dampers are working properly.

 Even if you do all that, you could be missing one crucial step, a step that could knock you out of work for a week. Without sanitizing your condenser and evaporative coils, you can easily get sick from contaminants in the air.

What kind of contaminants? We’re talking about mold. Mold spore growth in HVAC systems is a perfect example of why our product, Fast Attack, exists.

Just cleaning the system won’t keep mold from developing. The system must be sanitized to prevent mold spores from growing in the HVAC system, which for mold spores, is an ideal growing environment.

Here’s what one of our many valued clients had to say about our fantastic sanitizing product, Fast Attack:

Technical Corner: Benefits of HVAC Sanitizing

It is common for interiors of air conditioning equipment to develop bacteria and mold growth. These are not only a source for allergens for people, but create other problems as well.

Actually the buildup of microorganisms in air conditioning equipment is much greater than most people recognize. It can be quite significant, and effect not only building occupants but the cash flow of commercial buildings.

Cooling coils require clean coil fin surfaces to cool the air. But they become coated with films of bacteria and fungus. These biofilms insulate cooling coils – it’s like putting a winter coat on in the summer time. Your unit just has to run longer to cool the air.

Of course, longer running of equipment means using more electricity – as much as 40% more according to the ASHRAE Journal.

Since the HVAC system uses about half of all electricity consumed by a commercial building, periodically removing bio films from coils is financially beneficial for the building owner.

In addition to wasting electricity, another unfortunate fact is that fungus and bacteria grow quite well in the dark and damp interior environments of air conditioning equipment. Growth occurs in such quantities that even half-inch drain lines can get completely plugged up with slime, resulting in expensive condensate pan water overflows.

Along with the growth of fungus and bacteria, foul smelling odors are emitted by decaying microorganisms. Moldy smelling units are dirty, biologically contaminated units.

But there is a way out of this.

Using Fast Attack HVAC Sanitizer quarterly can do much to reduce or eliminate these microbes and the decrease of efficiency they cause. It’s easy, and cost-effective to use. You’ll be glad you did.

From the Field: What Affective Communication Can Achieve – ACCA

483820_192322967558346_770339834_n
At the end of February I had the pleasure of attending the IE3 show in Orlando, Florida. In the three years I have worked at CRT, this was only the second time I’ve attended this show, and one of only a handful of shows I have been to thus far. However, this show was probably the most enjoyable and informative, and may well prove to be our most successful.

The IE3 Show consisted of members of the Air Conditioning Contractors of America (ACCA), the Indoor Air Quality Association (IAQA), and the Residential Energy Services Network (RESNET). These three groups amounted to over 2500 decision makers attending the three day expo. With 220 exhibitors, this amounted to a very favorable 11:1 ratio. Our primary focus this year was reaching more members of ACCA.

While last year’s show seemed to be focused more on how to stop losing business during a struggling economy, this year’s show had a much more positive atmosphere. Even the attendees were in amazing, optimistic moods open to new ideas and products.

Our booth was constantly busy. Of course, Pancrete, our condensate pan resurfacer, grabbed everyone’s attention; but what was surprising was how many people that don’t necessarily work in units, such as raters and consultants, took an interest in what we offered. People were looking at ways to grow business, for new products and application, and to make the business they already have more profitable through customer interaction.

While many of the seminars in the IAQA and RESNET tracks focused on mold and energy services management, ACCA steered more into business growth and client communication. From the show’s opening session, which focused on building relationships with clients to create results, and continuing through to the learning labs, ACCA’s focus was clear. At least 17 of the 42 seminars dealt with communication, whether through managing employees, handling customer questions, or growing social media.

I was able to attend four sessions, dealing with managing sales, customer service communication, and increasing your social media footprint, and all were expertly presented and well received. These classes discussed managing processes, not people; listening, not simply hearing; spheres of influence and what you can and cannot control; and how much and often social media should be used by your company.

Overall, I came away from the conference not with just amazing leads, but new ways to approach both customers and co-workers. I would definitely recommend anyone in the HVAC industry to attend next year’s show, March 17-20 in Nashville, TN. I hope to see you there.

Product Spotlight: Airing Out Your Dirty Laundry (Socks)

Practically all items inside of buildings contribute to indoor air quality. Everything from carpeting to office equipment release gases and particles known as volatile organic compounds (VOCs). However, the most referenced cause of indoor air quality concerns by tenant and workforce populations is the HVAC system. These concerns are a result of the strength and frequency of undesirable odors being disseminated by HVAC systems.

Contaminated outside air, bacteria and mold are thought to contribute to many health issues. Unfortunately this is quite common, as the interior of HVAC systems provide the perfect growth environment for spores to become active. Along with providing a dark, temperature-controlled area, HVAC systems remove moisture from the atmosphere providing mold spores with water, and remove dirt and debris providing mold spores with food.

Controlled Release Technologies, Inc. (CRT) has developed the following solutions to help buildings maintain positive indoor air quality, and avoid odor problems originating in the HVAC system. By using these products, air handler units can remain clean and sanitized. Additionally, the time between cleanings and the life of the unit itself can be increased, and the chance of poor indoor air quality can be dramatically decreased.

The Dirty Sox Kit is an annual, three-step application process developed by CRT that rids HVAC air handler units of odors by cleaning, sanitizing and protecting the evaporator coil. It is generally applied in the fall or winter months, and in systems where Dirty Sock Syndrome is thought to be present.

Dirty Sock Syndrome is a term coined by industry experts to describe unidentifiable odors which building occupants equate to the smell of dirty laundry or a gym locker room. Dirty Sock Syndrome is believed to be a result of bacterial growth on HVAC evaporator coils. The problem is generally limited to heat pump systems, but may be noticed in other system interiors.

Dirty Sock Syndrome is prevalent in buildings located in hot, humid climates, where there is a constant supply of moist air exasperating the problem. Because a microbial can grow quite rapidly, the emission of odors increases over time.

Follow these steps when applying Dirty Sox Kit:

  1. Apply Instant Powder Kegs coil cleaner to clean the evaporator coil of deposit buildup.
    Instant Powder Kegs is a concentrated cleaning powder, that is mixed with water at the job site, saving users expensive and unnecessary shipping charges. Instant Powder Kegs removes dirt and odor-producing build up that hinder the efficiency of HVAC systems.
  2. Apply Fast Attack to sanitize the coil, and remove any odor-causing algae, fungus, bacteria or mold.
    Fast Attack is an EPA-registered, concentrated antimicrobial that cleans as it sanitizes. Iodine was chosen as the active ingredient, as its effectiveness is well known and widely used in hospitals and laboratories.
  3. Apply First Strike Micro Coat to the coil surface to protect against future buildup of dirt and contamination.
    First Strike Micro Coat provides a clear molecular barrier (less than one micron), that does not inhibit heat transferability. Because First Strike Micro Coat has been extensively evaluated, it performs without maintenance attention for a year or more. This decreases redundant labor costs and coil cleanings, and keeps coils performing at optimal energy usage.
