Why Add Duct Sanitizing to Your Duct Cleaning in Duluth?

Wednesday, July 30th, 2014

Up to 40 pounds of dust is created annually by those living in your home. That’s a lot of dust. And because your air conditioner circulates the indoor air, this dust gets sent through your system and will eventually settle in parts of it. The air filter that comes with your air conditioner will capture part of this dust and dirt, but it won’t get all of it, which is why it’s recommended your ductwork is cleaned every 3-5 years. Sometimes, though, ductwork can provide wonderful environments for biological pollutants like mold, fungus and dust mites to grow and thrive, and cleaning may not be enough to remove them. This is when you may want to consider having your ducts sanitized with your next duct cleaning in Duluth, GA.

What Is the Difference Between Cleaning and Sanitizing?

During a duct cleaning, high-powered vacuums and agitation devices remove dust buildup and attached debris from your system. This kind of cleaning is very thorough, and while it can remove things like mold growth, it does not kill the spores that produce them. With sanitizing, your ductwork is treated with safe chemical sanitizers that can destroy microbial growths and prevent them re-occurring.

What Kind of Chemicals Are Used to Sanitize?

Each company will have a preference for the chemicals they use for sanitizing ductwork, but here are 2 common ones that are EPA approved and used frequently in the industry:

  • EnviroCon – this sanitizer has low toxicity and has a positive safety rating from the EPA. The main purpose of this chemical is to destroy and eliminate problematic organisms such as mold, mildew and bacteria, and it does so by using a chlorine dioxide release process that destroys these kinds of organisms at their origins. It also eliminates any odors caused by growths of these biological pollutants.
  • Microban – this chemical is used to destroy and eliminate most fungi, bacteria, viruses and allergens, and also destroys any odors associated with these pollutants. Microban cannot be purchased in stores and should only be used by trained professionals.

Who Should Consider Duct Sanitizing?

Duct sanitizing is a service to consider when you’ve experienced the following in your ductwork:

  • Mold and/or mildew growth
  • Fungi growth
  • Pests (both insect and animal)

You may also want to consider duct sanitizing if you have general concerns about biological pollutants in your vent work.

Duct Sanitization Is Not a DIY Job

Proper duct sanitization requires professional knowledge of ductwork and duct cleaning, as well as the training to handle professional-grade sanitizing chemicals; as such, it’s best to leave a job like this to a trained expert. Call Cool Air Mechanical today and see if duct sanitizing in Duluth is something to consider with your next duct cleaning.

Tools Used for Duct Cleaning

Tuesday, July 15th, 2014

Here’s a suggestion for cleaning your home’s air ducts: go pull out the vacuum cleaner from the closet that has the long hose. Unscrew the grate from over one of the room vents. Turn on the vacuum cleaner and push the hose down into the duct beyond the vent and move it around for a few minutes while it sucks up the thick clogs of dust, carpet and furniture fibers, pollen, and dander. Put the grate back over the vent, and move onto the next vent and start the process again.

It sounds so simple, doesn’t it? Yes… because it’s too simple, and it doesn’t work. In fact, there’s no “do-it-yourself” solution for cleaning your home’s ductwork. The extent of your ventilation system and the level of contamination that can develop inside it require professionals equipped with specialized tools to handle the job. Fortunately, it’s easy to schedule the work: just call Cool Air Mechanical and talk to our team of experts in duct cleaning in Decatur, GA. We will handle the work with the best tools available and the training to use them.

Professional Duct Cleaning Tools

  • Power vacuums: The vacuums used for duct cleaning are large, industrial strength machines that attach to your forced-air HVAC system to access the network of air ducts. These vacuums are capable of placing an entire ventilation system under “negative pressure” that causes contamination to lift away from the interior surfaces of the ducts. Once the vacuums have altered the pressure inside a ventilation system, they then use powerful suction to remove the majority of particles.
  • Agitation devices: This term covers a large number of rotary brushes and vacuum hose attachments. They are designed to snake deep inside vents on long cables to loosen debris from the walls of ducts (without damaging the duct material) and allow for easier removal. Agitation devices are used to target specific areas of trouble that a power vacuum might not be capable of affecting.
  • Video inspection systems: How can duct cleaners know they need to target certain areas? They use video inspection equipment that can enter the ducts to examine contamination levels and the sources of blockages that are causing airflow troubles. Technicians often use this high-resolution camera equipment to provide “before and after” views to show how effective other cleaning methods have been.

You should schedule regular professional duct cleaning in Decatur, GA (we recommend that most homes have cleaning done every other year) to protect your HVAC system and your indoor air quality. Call our duct cleaning experts at Cool Air Mechanical today for top-level professional services that make use of the finest equipment available.

How Your Ducts Become Dirty

Thursday, June 12th, 2014

How clean are the ducts in your home? If you haven’t scheduled regular professional cleaning for them in two years or more, you might be in for an unpleasant surprise if you reach down inside one of the vents with a handheld mirror to get a view of the interior. No matter how clean a home you try to keep, your ducts will get dirty over time to the point that the dust, dirt, and other debris inside can have a negative impact on your indoor air quality and lower the performance of your heater and air conditioner, even leading to damaging them.

We’ll explain how your ducts get this way to help you understand why regular, professional duct cleaning in Marietta, GA is essential for maintaining clean air and a working HVAC system. To schedule quality ductwork cleaning, contact our air quality specialists at Cool Air Mechanical today.

How a Home’s Ductwork Becomes Dirty

Although a cleaner house will slow down how fast dust and dirt gather inside a ventilation system, no amount of cleanliness can stop the eventual build-up. The reason for this is that the ventilation system is constantly circulating the air inside your home, and any dirt and dust inside the rooms will eventually find their way into the ductwork. Since the ducts are sealed along their length to prevent the loss of air pressure, they are basically dust traps: as dirt and other particles enter the ducts, they become trapped inside with no way to escape (except to get blown back out into your air or dragged into the AC). Dust that you sweep up will fly into the air and into the return vents, joining the rest of the dust. Homes have such effective air sealing on them today to make them more energy efficient that there are few places to which the dust inside your house can escape.

You can ventilate your home with open doors and windows, but this 1) will not reach into and clean out the ducts, and 2) may bring in more foreign particles which will then become trapped in the house and circulated through the ventilation with the rest of the dust.

There is another potential threat to the interior of your ducts: mold. Mold spores can enter the ventilation system and take hold and start to grow in humid weather. If your home suffers from unusually high humidity, this can become a serious issue.

However, you have help available for all these problems: the indoor air quality experts at Cool Air Mechanical. We offer professional duct cleaning and other indoor air quality service in Marietta, GA that will remove this reservoir of dust and dirt from your home. We also remediate mold with UV germicidal lights, and offer dehumidifiers to help reduce the risk of mold growth (and increase your summer comfort). Give us a call today for cleaner ducts.

Mold Testing Question: What Does “Mold” Encompass?

Thursday, May 1st, 2014

Your home needs protection from mold growth to maintain a high level of indoor air quality. Experts can remediate mold through techniques such as fogging and targeting affected material with cleaning, encapsulation, or removal.

However, for proper mold remediation, your home needs to have mold testing (environmental inspection) to determine the cause of the mold growth and the particular types of mold that must be addressed.

What exactly does “mold” encompass? Although you are familiar with the mold that appears on old bread, you probably don’t know much more about what the inspectors will look for. In this post, we’ll go into detail about what mold testing covers and how some mold threatens human health.

Cool Air Mechanical offers mold remediation and mold testing in Atlanta, GA that will keep your home safe and comfortable. Call us today to schedule an environmental inspection.

Mold Inside Homes

Mold is a type of fungus that grows in multicellular filaments. (By contrast, yeast is a fungus that can grow as a single cell.) Not all mold growth poses dangers to humans, but a few common species do: mold testing targets these, although it will seek to eliminate all mold as a precaution.

According to the Center for Disease Control, the most common molds inside homes are Cladosporium, Penicillium, Aspergillus, and Alternaria. The molds that will affect indoor air quality are the ones that produce mycotoxins, which are responsible for the breathing troubles, irritations, allergic symptoms, and unique health problems that molds can trigger inside a home. These are referred to as “toxic molds,” even though the mold itself isn’t toxic; the spores it produces are.

The most problematic mold when it comes to health concerns is Stachybotrys chartarum, which can grow on fiberboard, paper, and within dust and lint. However, the danger level of Stachybotrys chartarum is irrelevant when it comes to mold testing, since, according to the CDC, “[i]t is not necessary… to determine what type of mold you may have. All molds should be treated the same with respect to potential health risks and removal.”

When you schedule mold testing, you target all the molds that might have developed in your house, regardless of their toxicity level. Expert mold testers will find where mold is growing and identify the methods needed to remediate it. Be assured that with professionals on the job, you will have all dangerous molds eliminated, along with the benign ones as well.

Cool Air Mechanical offers many services to improve your indoor air quality, from installing air filters to conducting mold testing, in Atlanta, GA. Call us today to learn how we can make your home a healthier place for your family.

The Importance of Spring Duct Cleaning

Friday, April 4th, 2014

With spring arriving in Georgia, we’ve reached the conclusion of the heating season. Our furnaces and heat pumps will go into hibernation (with maybe a few days return to work) and the air conditioners will start their regular hum keeping homes cool.

We hope you have scheduled maintenance for your AC—it should be done every spring. However, have you also considered having a thorough cleaning of the ductwork your air conditioning system uses to distribute cool air? Right now is an ideal time to schedule duct cleaning in Atlanta, GA. It’s a more important service than many people realize.

At Cool Air Mechanical, we not only keep the air in homes cool with repairs and maintenance on air conditioners, we also keep ductwork free from dust and debris with our specialists in duct cleaning. Call us today to schedule an appointment.

The Importance of Clean Ducts

During the winter, ducts can accumulate debris from the inside of your home. (If you haven’t regularly changed the air filter, the accumulation can be thick indeed.) When your AC comes on for the season to stay, you want the cleanest ducts possible to welcome it. Here are the reasons why:

  • Healthier air: One of the reasons that low indoor air quality plagues many homes today is because they are sealed up tight to help save energy – which prevents fresh air from coming in. Instead, the air circulates through the ducts—and if they’re filled with contamination, it will spread through the air you breathe. Duct cleaning reduces health problems caused by low indoor air quality: you’ll experience fewer colds and flus, as well as a reduction in eye and nose irritation, headaches, nausea, and breathing trouble. If people with allergies live in your home, it’s especially important to maintain a clean ventilation system.
  • AC efficiency: Ductwork is designed to provide as little resistance as possible to the flow of air from a heating or cooling system. Even a thin layer of dust inside ducts creates friction on the airflow and makes the air conditioner work harder than it should. Over a one or two year period, this will severely affect performance and lead to higher utility bills. Duct cleaning will save you money with an AC that has few obstacles to its airflow.
  • Prevent AC repairs: Dust and debris clogging ventilation does more than restrict the airflow. It can damage the system as well. When particles get through to the cabinet of an air conditioning system, it can cause motors to burn out, fan blades to bend, and compressors to malfunction. A good cleaning of the ducts means an air conditioner that will run during the spring with fewer chances of developing malfunctions.

Don’t try to clean ducts on your own. It takes special equipment and training. For duct cleaning in Atlanta, GA, rely on Cool Air Mechanical and our experienced team.
