What Is Duct Sanitizing?

Friday, March 20th, 2015

If you worry about the quality of the air in your home, duct cleaning may be a great choice for your family. With duct cleaning, professionals go after the most common contaminants in your ducts which may affect your family’s health. And in some cases, you can get duct sanitizing for further protection against bacteria and viruses. Talk with the experts at Cool Air Mechanical for more information and to schedule complete duct cleaning service in Alpharetta.

What is involved with duct sanitizing?

Duct sanitizing is the very last step in duct cleaning, and it is entirely optional. In some case duct cleaning is already sufficient. Technicians use agitators and high-pressure vacuums to knock debris loose from the lining of the ducts and suck it up. They’ll use professional inspection equipment to make sure the job was completed properly. And finally, some companies ask clients whether they would like duct sanitizing as well.

With duct sanitizing, our technicians use an EPA-approved cleaning agent to further eliminate microbes and other contaminants from the ducts. There are very few products out there approved for this by the Environmental Protection Agency and OSHA–the Occupational Safety and Health Administration, which is why it’s important to choose the right company for this task.

Do I really need duct sanitizing?

The fact is that not every home will require duct sanitizing. We usually recommend this service only to our customers who suffer from asthma, allergies, or severe immune disorders. You may decide to add on duct cleaning at the end of your service for this reason, or you may choose to if the level of dust in your ducts was particularly high. The choice is yours, but keep in mind that this process is safe for your home and for the air you breathe. However, we can only sanitize sheet metal ducts at this point, as there is no approved process for fiber duct board.

When you decide it’s time to schedule duct cleaning in Alpharetta, choose a company who uses the right tools and methods and who gives you the option to add in duct sanitizing. Not every company offers this valuable service, so put your trust in Cool Air Mechanical. Call our highly skilled indoor air quality team today.

Contaminants Sometimes Found in Air Ducts

Wednesday, February 18th, 2015

The first home HVAC system air filters were actually designed to keep particles out of the air handler of the heating and air conditioning equipment. If large particles were to move from the air in your home into the blower fan, it could hinder performance, causing the fan to slow down and potentially jamming the motor. Dust can also clog the burners of a furnace or keep the air conditioning coils from absorbing heat effectively.

Just like the air filter in your car, the air filter in your air conditioning and heating system protects the parts of your unit from damage. But today’s filters serve a second purpose, eliminating unsafe particles from the air that you breathe. Because air cycles frequently through the ducts, it’s important to have some form of defense against pollutants that could aggravate allergies and irritate the lungs.

But a standard air filter doesn’t guarantee that all of the contaminants that could enter the ducts are deterred. In fact, most home air filters are ineffective at removing even the most common home contaminants, such as mold spores, which could then move into the ducts. Many of these contaminants stay dormant in the ducts for a while, infiltrating the home from time to time and irritating household members’ allergies and other respiratory conditions.

The following contaminants may be contained within your duct system. Experts recommend scheduling duct cleaning once a year in some cases, or as often as your technician recommends it.

  • Dust mites: Dust mites thrive in warm, humid areas, and the ductwork may be a perfect location. As one of the most common allergens found in homes, dust mites can irritate those with allergies and may even trigger asthma in children.
  • Pet Dander: You may not have a pet in your home due to your allergies, but what about the homeowners who came before you? Duct cleaning is especially important for people with severe allergies, especially if they seem to act up often.
  • Bacteria: There could be some harmful bacteria present in the ducts that could make family members ill, particularly those with immune disorders.
  • Mold: Finally, mold survives on wet surfaces, like the indoor air handler of your air conditioning system, and could spread to the ducts.

What You Need to Know about Duct Cleaning

Wednesday, January 14th, 2015

Though you may not know it, your home’s air ducts are some of the most important pieces of infrastructure in the entire house. They make central heating and air possible in the first place, and keep the rooms in your home from getting stale by circulating fresh air. They also happen to be among the most commonly neglected parts of your forced air system when it comes to maintenance. Let’s take a look at why it’s so important to have your ducts professionally cleaned.

Airborne Pollutants

Believe it or not, the air in the average home is infested with microscopic pollutants and contaminants. Most of these are only minor inconveniences. Pollen, dust, and insect dander often provoke allergy attacks and the like. However, there are nastier things like bacteria, viruses, and mold that are regularly found in a home’s air supply.

These airborne pollutants are most often found in the ductwork of a home, for a number of reasons. The ducts are often out of the way, beyond the reach of a homeowner’s normal cleaning efforts. They are also dark and more susceptible to moisture; an ideal environment for mold growth. The biggest problem is that every time a forced air system is turned on, the ducts serve as a transportation network for these pollutants. They are spread around the house in this fashion, making it more likely that they will have a negative effect on the occupants of the home.

Duct Cleaning

Duct cleaning attempts to address these pollutants by clearing out their ideal environment. A professional will either vacuum out the entire ductwork, or use a set of specially designed brushes to carefully clean out any dust and other debris. After the initial cleaning, any leaks that can let moisture in can be found and sealed. In some cases, a chemical treatment can be applied to kill off any bacteria. Duct cleaning improves your air quality by ensuring that the “lungs” of your home are healthy. The healthier your ducts are, the healthier you will be.

If you haven’t had your ducts cleaned in a while, call Cool Air Mechanical. We provide professional duct cleaning services in the Roswell area.

Signs It’s Time to Schedule Duct Cleaning

Thursday, November 6th, 2014

One often-overlooked, but important, part of your heating system is the ductwork. Ductwork gets just as dusty and dirty as the components in your furnace, and, with time, the buildup of dust and dirt can become significant. While your ductwork doesn’t need to be cleaned annually, it is strongly suggested that it is cleaned every 3-5 years. If your last duct cleaning in Atlanta was more than 5 years ago, you may see the signs that your ductwork has significant dirt and dust build-up. Remember that, for all of your ductwork needs, the trained and certified technicians at Cool Air Mechanical are ready to assist, so call us today.

Signs It’s Time for Duct Cleaning

Here are some of the common signs that your ductwork needs cleaning:

  • Increase in energy bills – when excessive dust and dirt line the inside of your ductwork, they can restrict the air flow in your system. This restriction forces your heating system to work harder; as a result, it uses more energy.
  • Noticeable amounts of dust in your home – is your home getting dustier even though you regularly clean it? The excessive dust from your ductwork has a direct route into your living spaces and can accumulate on furnishings.
  • Increased allergies/cold symptoms – are you seeing a lot of extra sneezing and coughing in your home? The dust and contaminants from your dirty ductwork may be causing irritation for those in your home, particularly the allergy sufferers.
  • Strange odors – do you notice unpleasant smells coming through your vents when the heat comes on? There may be pollutants in your ducts, and unless it is removed and your ductwork cleaned, it will continue to flourish.

Fall is the perfect time for maintenance on your heating system, so why not include duct cleaning? Professional duct cleaning in Atlanta can help improve your energy efficiency and comfort, and keep your indoor air quality high. Call Cool Air Mechanical today and schedule an appointment with one of our experts.

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.

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.

Can I Clean My Air Ducts Myself?

Monday, March 3rd, 2014

Regular cleaning for your home’s network of air ducts is an important part of maintaining the efficiency of your HVAC system, shielding the ductwork from damage, and protecting your indoor air quality. Depending on how much dust, dirt, and other contaminants enter your ducts, you will require cleaning every one or two years. Sometimes you’ll need cleaning done earlier if the ductwork has become heavily congested.

To have duct cleaning in Atlanta, GA done properly, you must hire professionals. We understand that many people have DIY hobbies and enjoy the idea of independence. But when it comes to duct cleaning, you cannot handle the task on your own. The job requires more than a long-handled broom, a few rags, and a bottle of commercial cleaner. Call up duct cleaning specialists, like those at Cool Air Mechanical, to schedule the work.

The reason that duct cleaning requires trained professionals is because of the extent of the ductwork in your home and the nature of the contaminants that can get inside it. Most of your ductwork is hidden behind walls and ceilings, making it difficult to access. You can reach parts of it by unscrewing vent covers, but this is hardly enough to provide a thorough cleaning. Professionals use high-powered vacuums with long hoses to reach inside your ducts to places that you can’t on your own.

Professional duct cleaning also requires agitation equipment to remove particles embedded deep into the walls of your ducts. Standard cleaning methods, even powerful vacuums, cannot get out many of these contaminants. Duct cleaners use agitators to first loosen these pollutants. This equipment includes rotary brushes on long cables and special vacuums hooked onto the blower of your HVAC system that puts the entire ductwork under negative pressure. After using the agitation equipment, the duct cleaners can more easily remove the dirt particles and other debris.

Finally, duct cleaners often use special sanitizers on the ducts to remove allergens and pollutants that can cause cold and flu-like symptoms. These sanitizers are designed to avoid leaving lingering chemicals in your air or cause damage to your ducts.

Although you can’t perform a thorough cleaning for your ducts on your own, it’s easy to discover if you need to call for duct cleaners. Unscrew the cover to one of the vents in your house, and then reach inside and use a digital camera with a flash to take a snapshot of the interior. If the image shows heavy clots of dust, it’s time to call for experts in duct cleaning in Atlanta, GA.

Cool Air Mechanical can handle cleaning out your home’s ventilation system. Our duct cleaners use the best equipment available to leave you with ductwork that will keep your air clean and your heater and air conditioner happy.

The Tools Professionals Use for Duct Cleaning

Thursday, February 6th, 2014

You should schedule duct cleaning in Atlanta, GA once or twice a year to make certain your heater and air conditioner have as little resistance to smooth airflow as possible and to ensure that you have high indoor air quality. Because your ducts are sealed along their length to prevent losing air pressure, they can develop a buildup of dust, dirt, pollen, and dander that has no escape except through your vents. In addition to standard pollutants, ducts can harbor bacterial contaminants that can damage the duct material and negatively affect your health. Duct cleaning is vital for taking care of these problems.

Duct cleaning requires trained professionals with advanced tools. Without the equipment listed below, it’s impossible to access all the spaces inside ductwork or to remove the majority of the contaminants. Put this job in the hands of the experts: call Cool Air Mechanical today and schedule the duct cleaning you need.

Common tools for professional duct cleaning

  • High power vacuums – These specialized vacuums have a stronger level of suction than even most commercial vacuum cleaners. They have long hoses capable of reaching far inside ductwork. But most important, they dislodge contaminants from the walls of ducts by placing the ductwork under negative pressure. This makes it much easier for the vacuum to remove contamination.
  • Rotary brushes – To scrub away the most ground-in dirt and loosen then for vacuuming, duct cleaning technicians use motorized rotary brushes on extended lines. The fast-spinning action of the brushes can dislodge most contaminants without causing damage to the interior of the ductwork.
  • Sanitizers – Using vacuums and brushes does the work of removing dust and dirt, but for the job of cleansing out bacteria, viruses, or mold spores that lurk inside your ducts—which are common in the humid climate of Georgia—the duct cleaning technicians will use special sanitizers, which will not reduce the quality of your indoor air. These sanitizers not only eliminate most bacterial contaminants, but they prevent them from recurring. We recommend this service to our customers who have experienced recurring flu-like symptoms or asthma.

Some of these devices are available for purchase on-line (it seems nearly anything is available on-line now), but not only are they prohibitively expensive, they require training to use. It’s must easier for you to contact a specialist in duct cleaning in Atlanta, GA to handle the job.

Cool Air Mechanical has a staff of technicians we selected based on their extensive training. They will arrive at your home with the tools and the knowledge necessary to give you the cleanest ductwork possible.
