How Your HVAC Is Contributing to Poor Air Quality

Did you know that about 1 in 13 Americans have asthma and that these numbers are increasing every year? Additionally, even more people suffer from allergies that range from seasonal to severe.

Sneezing, coughing, and runny noses are mainly associated with allergies caused by outdoor seasonal triggers. However, people fail to realize that poor indoor air quality can cause coughing, sneezing, watery eyes, dry eyes and throat, fatigue, dizziness, headaches, and upper respiratory congestion. Indoor air quality is not usually a topic that comes up when someone in your house is under the weather however indoor air quality needs to be examined for a healthy life.

According to the Environmental Protection Agency, the quality of the air inside of your home can be up to 10 times more polluted than the outside. You might be wondering how this is possible, well a few of the factors contributing to poor indoor air quality include tobacco smoke, cleaning and hygiene products, air fresheners, furniture, and even your HVAC equipment.

How the HVAC System Impacts Air Quality

When your HVAC unit is working properly, it should bring outside air into the home, filter it and make it cleaner and healthier for your household and then redistribute it at the right temperature throughout your home. However, this does not always happen.

If the HVAC system is not functioning properly or if it has not been maintained properly, unwanted pollutants will get into the home, and these unwanted particles will accumulate in the ductwork and recirculate throughout the home.


Pollutant particles can also enter an HVAC system through the return air supply. Common household pollutants such as dust, pollen, animal dander, skin cells, and hair are pulled through the return registers when the HVAC draws in air. The filter in the HVAC system is responsible for catching these particles.

It is important to change the filters on your system when required. Filters will capture the contaminants and prevent the majority of them from entering back into your air space. They also ensure that those particles won’t clog your system. If the filters are left unchanged, those particles end up in the HVAC equipment, ductwork and eventually back into your living space as a vicious cycle.

Air Ducts and Vents

The same goes for your air ducts and air vents. These are great places for dust, dirt and other allergens to accumulate, especially if you don’t take the time to clean them regularly.

HVAC Maintenance

Investing in routine maintenance for your HVAC system will help safeguard your indoor air quality and prevent contaminants from circulating throughout the home. An HVAC professional will check the components of the system to make sure everything is working in a way that provides the best indoor air quality possible.

A well-maintained system could save you money, provide cleaner air to breathe, increase the comfort in your home all the while boosting occupants health due to better indoor air quality. Don’t let your home contribute to the incredibly high asthma and allergy rates in America, and don’t let your home’s air quality be worse than the air outside. Take the necessary steps to ensure you’re breathing clean and pure air.
