If you find that some of your family members have fallen ill or are suffering from an extreme case of allergies, this could be a sign of your HVAC system’s air filtration not maintaining the quality of your air correctly. If this is the case, then it is time that you got your air filtration serviced.

What Causes The Indoor Air Quality To Decrease?

The quality of the air inside your home is based on how your indoor environment is reacting to other aspects of your home. There few reasons as to why your indoor air quality can decrease.


Your HVAC system, (Heating, Ventilation, and Air Conditioning), is the soul behind keeping the temperature, humidity, ventilation, and air circulation working within your home. If your HVAC unit loses control of any one of these elements, then the whole system could be thrown off causing the air quality within your home to decrease.

This is why it is extremely important to have your HVAC system undergo regular maintenance to avoid any malfunctions that could affect the quality of your air. But we will get back to that in a bit.

Presence of Contaminates

Your home’s air is reliant on more than just the proper functioning of your HVAC system, but it is also dependent on the cleanliness of your home. As your mother probably said, “cleanliness is next to godliness,” which is the gospel truth concerning your air quality. You see, harmful molecules from dust, mold, and bacteria can get swept up into your air by people, or even a breeze, passing by. When this happens, it sticks in the air, contaminating it, and eventually making its way into you and your family’s lungs. Proper maintenance of your home, such as a weekly dusting, vacuuming, cleaning the walls and furniture, ensuring that there is no damage to roofs, windows, or walls that would allow for leaks, can all help avoid this problem.

Proper Cleaning Of Your Home Filtration System Can Keep Your Air Quality Pristine. 

It isn’t just about cleaning though, you need to make sure that you are taking the right safety protocols when cleaning your home. Chemicals, such as Clorox, do a fantastic job at fighting off dirt but can also harm your body. In order to avoid contaminating your air with these chemicals or the threat of directly breathing them in, it is important that you always make sure that the area that you are cleaning is properly ventilated to ensure that the chemicals have a place to escape instead of becoming wrapped around you. This will help you avoid any negative health effects that can come from breathing them in, such as nausea or dizziness.

Also, no matter how strong your HVAC unit it, it cannot completely control the quality of air in your home when it faced with a serious problem such as a gas or sewage leak. These types of problems are a real cause for concern, as they can put your whole family in danger of becoming ill or causing some major damage to your home and property. If you notice a gas leak or a problem with your sewage line, it is extremely important to get these taken care of right away.

What Are Common Indoor Air Pollutants?

Besides the ones listed earlier, three of the more serious air pollutants are radon, mold, and volatile organic compounds. Here is just a quick rundown of these pollutants.


Radon is a type of radioactive gas that in high doses can lead to major health concerns such as lung cancer. Radon is naturally in the air we breathe when we go outside, and a small amount will not hurt you. But as the saying goes, too much of anything can be harmful. Radon becomes deadly when it gets trapped within your home and the level of it begins to spike. It can get into your home by seeping in through the natural pores in your floor or through cracks in your windows or walls. When this happens, your HVAC system can usually knock it out, but if that is malfunctioning, then it no longer has the power to help filter out the radon, leaving your home in danger.

Mold (Mold Spores)

When mold grows in your home because of a leak in the roof or perhaps a faulty pipe, then the spores can become detached and drift in your air. Small amounts are harmless but if the problem is not taken care of, it can have a huge negative impact on those who have asthma or allergies. It can make people with a weakened immune system sick, and in general, just isn’t good for anyone to be breathing in. This can be handled by ensuring that your roof is properly taken care for and that you do inspections on windows and walls to make sure there are no cracks. Any broken pipes should be taken care of as soon as they are noticed to avoid future problems.

Volatile Organic Compounds

Volatile Organic Compounds are harmful substances that can be found off of paint and certain chemicals. As mentioned before, it is important to make sure that whenever you are doing anything in your home that involves chemicals or paint, that there is proper ventilation to avoid breathing the chemicals in.
