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!

5 Reasons To Clean Your Carpet & HVAC System

Have you ever thought about how dirty your carpet is? What’s more, have you thought about the bacteria living in your carpet? Are you curious about what’s right under your feet, or swirling in the air around you? If so, read on!

According to 50 Random Facts About…Carpet:

  • The virus that causes the stomach flu can survive on uncleaned carpet for over a month! 
  • Every year, several pounds of soil can accumulate in and under carpet. 
  • Did you know that the 5-second rule is a myth?  Bacteria can live for four WEEKS on carpet. AND thanks to microbial adhesion, germs like salmonella are immediately transferred to food that gets dropped on the floor.
  • All carpet should be professionally cleaned a minimum of every 12 to 18 months. 
  • When properly cleaned and maintained, carpeting may improve the quality of air by trapping allergy-inducing dust and allergens. Most people, though, don’t clean their carpets correctly, which can actually make allergies worse.

You may be wondering, what do these random facts have to do with my HVAC system?

  • Much like the carpet being a place for bacteria to adhere to, an HVAC system is the perfect place for bacteria or allergens that can harm you or your family. How does that affect you? The air you breathe comes right out of your heating and air unit.
  • Have you taken a look at your coils lately to see how clean they are? You are breathing the dirt, debris, hair, dander, particles and bacteria that are present on your coils because the air gets pushed through your coil, into your ductwork, and eventually into your home or building. 
  • Take it a step further – check the bottom of your drain pan. Do you see any build-up? That’s the condensation off of your coil. What you see in the bottom of that pan came from the coil. THAT’S what you and your family are breathing. 
  • If you’re concerned about your carpet holding viruses or bacteria, you should be just as concerned about what your HVAC system is harboring! Professionals suggest having your AC unit maintenanced every year, usually at the beginning of spring.

Last but not least: 

  • When properly cleaned and maintained, clean coils and drip pans will improve the quality of air in your home! But just as with carpet, many people don’t get them cleaned. That results in poor air quality and a shortened life for your HVAC unit.

Think about it! To keep you and your family healthy, it just might help to leave your shoes at the door, get your carpet cleaned and get your HVAC system maintenanced by a licensed HVAC professional. It’s never too early to start!

Tips From The Girls: Behind the Scenes of Your Sanitizer

When cleaning any sort of surface it is important to utilize some sort of sanitizer, otherwise, you leave behind large amounts of contamination consisting of settled – soils and debris. Non-sanitizing can also result to illness causing microorganisms.

Currently, there are three known based sanitizers: Chlorine (Bleach), Quaternary Ammonia (QUAT, QAC), and Iodine.

The common of the three, is the chlorine concentrated sanitizer, as it is usually inexpensive and effective against all bacteria. Quaternary ammonia are more effective on organic materials, and its major advantage is that it leaves behind residual antimicrobial films.

Lastly, you have Iodine Concentrated Sanitizer – which is what we offer here at Controlled Release Technologies. Iodine Sanitizers are fast acting and effective against all bacteria. Concentrated Iodine is nontoxic, non-irritating to skin, stable, and is often used in the Medical Field during surgeries and mainly, for cleaning wounds.

Our Fast Attack (Iodine Concentrated Sanitizer) has a concentration of 35% Iodine, which is a perfect combination, not using enough sanitizing agent will result in inadequate reduction of microorganisms. However, using too much sanitizing agent can be toxic causing further harm.

Any questions? Leave a comment below. I would love to answer your questions and help you further understand the importance and the difference between sanitizers.

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.
