Why is it important to clean and maintain your air ducts at home or business?

Each and every modern residential or commercial building has an integrated heating, ventilation and air conditioning system known as HVAC for short. This system uses air ducts for transferring of forced air from one place or another. These components are crucial for its efficiency. They are well designed and well built. The problem with them is that they accumulate large amounts of dust and dirt and often other contaminants which easily get into rooms and reduce the air quality. This and other related issues can be resolved or effectively prevented with cleaning and maintenance.

Air duct cleaning involves the removal of various types of substances from the walls of the ducts This is done with the use of special tools and techniques, which correspond to the design and complexity of the duct system. Maintenance involves thorough inspection. In case of damage, immediate repair is required. In some situations, replacement of the damaged component may be required. This is especially the case when duct insulation has been affected by moisture and mold. The major question is what results the cleaning and maintenance will bring. These include protection from contaminants and reduced costs for the household or business.

Health Benefits

The air which passes through the ducts of the HVAC system can pick up a wide range of particles from any dirt accumulations on the walls of the channels. The most commonly found particles are dust and pollen ones. When these are constantly pumped into the room, they can cause serious health problems including allergies and asthma. They can also make existing respiratory conditions worse. Children, chronically ill people and the elderly are at the highest risk.
Without proper maintenance, mold and other pathogens may grow on the inner duct walls. Mold has an adverse impact on the respiratory system. It poses a high threat of allergies and asthma. Other pathogens of various kinds and especially bacteria may also grow on the walls inside dirt accumulations. These pose a higher risk of various types of medical conditions. Some of the most dangerous contaminants include droppings of pests in case of infestation. These contain a variety of contagious viruses many of which pose a serious health hazard to humans.
With the provision of effective air duct cleaning and maintenance on a regular basis, these issues will be prevented. Everyone inside the building will breathe cleaner air which does not have contaminants coming from the inside of the HVAC system. These solutions are necessary for protecting the health and wellbeing of all people and especially of those who are vulnerable to health problems. When problems are identified timely and dealt with quickly, the potential health risk is reduced to the lowest possible level.
The maintenance of a clean and healthy indoor work environment is the obligation of every business. If this requirement is not kept, the company may run into serious issues and lose money and credibility. On the contrary, a clean and safe HVAC system can help to improve the productivity of workers and the overall business results as employees will be healthier and ask for fewer sick leaves. The single solution can have a major positive impact on the performance of the business.

Energy Savings

The presence of dust, dirt and other contaminants in the HVAC system has a negative impact on its operation. As accumulations build up, they reduce the efficiency of the system. As a result, it has to use a greater amount of energy to operate. Furthermore, in case the air duct insulation is damaged due to the works of moisture and mold, a greater amount of heat will be lost to the surrounding environment. These two factors result in higher energy consumption and higher bills.
You can save energy and money when the air ducts are clean and allow for the optimal functioning of the whole heating, ventilation and air conditioning system. This is an extremely important benefit for both households and businesses. The higher savings are beneficial for any budget. Households will have more money to spend on other things while business can increase their investment and profits. The generated savings can be used for the improvement of the system so that it becomes even more energy-efficient. The money can be invested in any kind of home improvement or commercial building improvement project which will generate further benefits. These can lead to the cozier home environment and better and more productive work environment.

Equipment Savings

In the case of dirt accumulations which bring down the optimal operation of the HVAC system, it has to work much harder to produce the required output in addition to using more energy. When all moving components operate more intensively, this increases the natural rate of wear and tear. The worn-out components have to be replaced more often and this will result in higher costs for keeping the system in optimal working condition.
This problem can be effectively resolved or prevented altogether with regular air duct cleaning and maintenance. When dirt does not speed up the wear and tear of the system components, you will enjoy the more reliable performance from the heating, ventilation and air conditioning units in the building. You will save a great deal on repair. The components will have a longer useful life and this can help to generate considerable savings.
Both households and businesses can save a lot of money. The bigger the HVAC system is, the higher the savings will be. This can have a major positive impact on the budget of households and especially of businesses whose lower costs can help for earning much higher profits. When all systems within a business organization are efficient, this helps for achieving even larger growth.
Overall, the importance of air duct cleaning and maintenance must not be underestimated. This plays a major role in the safety of the indoor environment and can help to improve the health and wellbeing of individuals considerably. It can result in great savings on energy and equipment replacement. The risk of issues due to lack of proper cleaning and maintenance is too serious to be underestimated. It is time to take action and make things right.

How accumulation of pollen in your Air Ducts can become a health hazard?

You have certainly seen pollen inside tree blossoms and flower blooms. This fine powder plays a major role in the reproduction of plants, but it can pose a great threat to humans. Every spring millions of people experience an allergic reaction to it and get sick. The problem can become even more serious when this fine powder gets stuck inside the air ducts of your house. All members of the family will be constantly exposed to this allergen. Find out more about this serious health threat.

The Danger of Pollen

Why is pollen such a great health hazard? The core of the problem does not lie with the natural powder itself, but with the immune system of humans. The immune system of some people perceives pollen as pathogen just like viruses or bacteria. As a result, it creates antibodies which fight the allergen when the person gets in contact with it. The body produces certain chemicals like histamine which produce undesirable symptoms. The main ones include blocked and runny nose, sneezing and watery and swollen eyes. It is possible for the symptoms to be greatly relieved, but the condition cannot be cured at least for now.

A person who suffers from pollen allergy will experience the symptoms only when exposed to the allergen. When pollen gets accumulated inside the air ducts and remains there, the exposure to the allergen can come constant and this can make the person’s condition much worse. It is generally quite easy for the fine powder to get inside the HVAC system during the spring and early summer as it is super light and sticky at the same time. Then when the heaters in the house are used, it is carried into the rooms by the warm air. When the air conditioner is used, it gets forced inside with the cool air. As a result, everyone inside the house is exposed to the allergen at all times.

Children, in particular, are at the highest risk of allergy caused by persistent exposure to pollen. They can experience the most severe allergic reaction and develop asthma as well. The elderly and people who already suffer from the respiratory condition can also experience much more intense allergy symptoms. These health hazards are extremely serious and must not be taken lightly.

Avoiding constant exposure

Since there are no medications for blocking the allergic reaction of the body, the healthcare providers recommend limiting the exposure to pollen as best as possible. The pollen accumulated on the walls of the air ducts can be effectively removed so that everyone in the family will be protected year-round. Air duct cleaning is recommended at least once a year. It can be done more frequently if required. When the procedure is performed properly, not only pollen but also all other allergens and pathogens inside the duct-work will be removed.

Finally, you should know that air duct cleaning is just one of the methods for protection from the health hazards posed by pollen. It is important for all filters in the HVAC system to be changed frequently. All surfaces inside the house must be cleaned regularly.


Why is ther an odor buildup in your Air Vents?

You can feel the bad odor coming from the air vents of your house or office. In some cases, the smell is persistent. In other cases, it comes and goes and its intensity changes over time. Even though the symptoms may vary, they are a sign of a serious problem which must be identified and dealt with quickly. Find out more about the main causes of a foul smell coming from the air ducts and how to resolve them.

Mold and Mildew

If there is a musty smell in the rooms and it does not go away no matter how often you open the windows or use an air spray, then you are most certainly dealing with mold or mildew inside the air vents. Both of these are types of fungus. They can have a variety of colors from white, pink, yellow and green to black. They can be damaging to surfaces and pose serious health hazards. Two conditions must be present for mold and mildew to grow. These are moisture and warmth. When the surface is moist and the temperature is above 65 F, the fungus will begin to grow and spread.

Mold and mildew usually appear in the air vents of buildings in warm and humid climates. However, they can also grow due to structural issues. When there is no proper insulation, for instance, the colder air easily gets into contact with the warmer surface and condensation appears. When moisture is present, the fungus is quick to follow.

In order for the issue to be resolved, the air vents must be properly cleaned. Special chemicals, which are deadly for mold and mildew, but safe for people and animals, have to be used. The cause of moisture must be eliminated as well.

Dead Animals

If there is a dead animal inside the air vents, the smell can be quite unpleasant and get more intense when the weather gets warmer. Most often, the animals found inside the ductwork are rodents, but it is also possible for the problem to come from birds and insects. The bad smell is not the only issue. Dangerous pathogens may be spread around the house.

In such cases, the source of the smell must be identified and removed. The air vents must be properly cleaned and disinfected. You must also take measures to prevent the access of animals into the ductwork.

Dangerous Gasses

Less often, the bad odor can come from gasses which have been released into the air ducts. If the heat exchanger of the HVAC system has a leakage, it will release combustion gasses such as carbon monoxide into the air ducts. These gasses can pose a serious health threat. Action for resolving the problem must be taken immediately.

If the structural components and finishes of a building release chemicals in gas form, they can be carried by the HVAC system and their bad smell can come from the air vents. In this case, the dangerous materials must be removed and all surfaces including the walls of the air ducts must be properly cleaned.

When there is a bad odor coming from the air vents, you must take the necessary steps to deal with the problem without delay.

How did bacteria get into your air vent?

We are surrounded by hundreds of thousands of microorganisms which we do not see. Some of them like certain types of bacteria can pose a serious threat to human health. The problem should certainly not be ignored. At the same time, it is not easy to resolve either. One of the main reasons for this is that bacteria can grow and thrive in totally surprising places such as the air vents. They can easily spread from there and pose a constant threat to people and pets in the house. In order to deal with these pathogens, you have to get an idea of how they got there in the first place.

Bacteria Basics

The reality is that bacteria are everywhere. These microorganisms are transferred around by people, animal and plants. They multiply and spread very quickly when they find the right environment. Most thrive in warm and fairly humid places. At the same time, their spores can survive in the harshest of environments for many years. When they find a hospitable environment, they simply begin to divide and spread.

Many bacteria are harmless. In fact, some are present in our body and play a major role in certain processes such as the breakdown and digestion of food. However, there are also ones which can be quite dangerous. Some cause infections of the gastrointestinal tract while others affect the respiratory tract. There are also rarer species which can attack vital bodily organs severely. For all these reasons, proper protection is required.

Transfer and Accumulation

Bacteria can be easily transferred through touch. They can travel in the air as well. Spores, in particular, can be carried by the wind and spread to large areas. Given that the HVAC system constantly circulates air inside the house and many of its components are regularly touched by people, it contains a considerable number of bacteria. The problem can be aggravated further by the presence of vermin in the system. They spread bacteria through their droppings and saliva. The dead bodies of these animals are also sources of dangerous pathogens.
When bacteria get attached to warm and fairly humid sections of the systems, they begin to grow and spread. In many homes, the air vents and the ductwork contain some moisture in addition to being warm. As a result, they make perfect spots for bacterial growth.
The accumulation of bacteria in the air vents increases the risk of infections in the inhabitants of the house. This is because these microorganisms are constantly spread with the circulation of air. Basically, the exposure of everyone in the house to bacteria increases considerably.

Effective protection

It is possible to reduce the growth and spread of bacteria in the air vents through proper cleaning of the entire HVAC system. You have to take appropriate measures to eliminate moisture and to reduce the level of humidity in your house. You must also take measures to prevent pest infestation. It is essential that you focus on keeping the entire home clean and maintaining a high level of personal hygiene.
You need to eliminate any bacteria present in your air vents and do everything necessary to prevent future growth.

Why does dust accumulate in your air vents?

You feel that dust is everywhere around your house. No matter how hard and how frequently you clean it, it keeps building up on surfaces. The issue may be due to dust accumulation in the air vents. When considerable dust deposits are present in the heating, ventilation and air conditioning system, the fine particles are simply circulated around the house and cannot be removed with regular house cleaning. The logical question to ask is how dust got built up inside in the first place.

Reduced filtration

The HVAC system uses a set of filters which capture dust particles and fine debris. These generally do a good job, but their efficiency is reduced with time. As the filters get filled with dust and dirt, their capacity falls down. As a result, a good amount of the particles get deposited inside the air vents. Despite the common misconception, the particles are quite sticky and can form considerably thick and large accumulations fairly quickly. The air which passes through the ductwork blows the particles from the topmost layer into the rooms of the house, but the rest of the accumulation remains. The air which is drawn from the rooms helps for the building up of the deposits.

As a result of this vicious cycle, the accumulations of dust inside the air vents and the ductwork increase over time and the indoor air quality deteriorates. Dust is not only unsightly. It is a powerful allergen. It can cause serious allergies, especially in children. It poses a higher risk of asthma as well. In people who already have an allergy, asthma or another chronic respiratory condition, the exposure to the fine particles can make the symptoms worse. For all of these reasons, the frequent cleaning of the air vents is essential. It will not only give you a cleaner indoor environment. It will help to improve the performance and energy efficiency of the HVAC system as well.

Ductwork Leakages

The other major cause of dust accumulation in the air vents, the presence of leaky duct pipes. Leakages can occur in all sections and for all sorts of reasons. Often, they occur around filters which are not properly sealed. This happens when the filter is too big for the opening and cannot get properly fitted. It is also possible for one or more ducts to have got detached. This can easily happen when the bonding is poor. Deeper scratches and holes of various sizes also lead to leakages.
When leakage is present, the HVAC system sucks air from the environment and circulates it around. Since leakages occur inside walls and in areas which do not get frequent cleaning such as the attic, the system sucks in a lot of dust as well. Then some of it gets circulated around along with the air. A good amount of it gets deposited onto the vents which become a constant source of dust. Again, a vicious cycle occurs. In order for this issue to be eliminated, the ductwork must be properly fixed and then maintained effectively.
It is possible to prevent dust from accumulating in the air vents and posing health risks. Take action straight away.

Can viruses accumulate in your air vent?

You have to know that it is perfectly possible for viruses to accumulate in your air vent. The more serious problem is that they can easily spread to the rest of the house via the heating, ventilation and air conditioning system and affect the people and any pets inside. Find out more about this issue and how you can deal with it.

The major sources

The reality is that all living creatures carry viruses. Some do not get infected with them, however, while others have built immunity against them. Basically, a virus which is completely harmless to one creature can be extremely harmful and even deadly to another. Given all this, everyone in the house plus any pets can spread viruses. Usually, they are transferred through direct contact. However, they can also become airborne and this can make their spreading much easier.

Viruses can also be spread by creatures which are present in your home without your knowledge. These include various types of vermin such as rodents, insects, and birds. They often spread a great variety of pathogens via their droppings. The dead bodies of these animals are also sources of dangerous viruses and bacteria.

Accumulation and spreading

The air vents are fairly warm and many are moist as well due to condensation and other factors. This makes them the perfect places for viruses to survive until they find a host. The good news is that they cannot survive long without a host. The bad news is that they can get spread easily and quickly from these parts of the HVAC system. This is because they are light and easily picked up and carried by air which is circulated through the system. Basically, the viruses can get pumped into the room directly at a high frequency. When they get in contact with your skin or you inhale them, you can get sick.
Traditionally, children and the elderly plus people with reduced immunity have been at the highest risk of viral infections. However, this does not mean that everyone else is safe. These extremely tiny microorganisms can get replicated in the cells in a matter of hours and affect various organs and systems of the body.

Treatment and Prevention

The two main methods for fighting viruses include cleaning and hygiene maintenance. They should cover the HVAC system of the house as well. The air vents, the ductwork and the other elements of the system must be properly cleaned. The ones which have air passing directly through them should receive proper sanitizing, if necessary.
The system components must be maintained in excellent condition so that the access of vermin is effectively blocked. If such creatures are present in the house and in this particular system, you must take all measures to eliminate them and to prevent future infestation. If the problem is serious, you may have to adopt a complete program for protection.
Finally, you should not panic about viruses accumulating in the air vents of your house. When you take him appropriate protective measures, you and your loved ones will be effectively safeguarded.
