Indoor air quality is a severely underrated aspect of your home. No matter how clear it looks, impurities may be lurking about. If the air is unclean, it can pose a serious threat to your health. Individuals with preexisting health conditions such as asthma and allergies are at an even greater risk. Fortunately, HVAC systems are a great way to solve the issue of air quality. With the right appliances, you can circulate fresh air throughout your entire home. In this post, we will learn how indoor air quality and HVAC are related.

Air Conditioning

First, it’s important to note that HVAC isn’t strictly a good thing when it comes to indoor air quality. Some devices such as AC units can actually have negative effects. An AC constantly sucks air in and out of the device, stirring up particles that already exist in your home. If you have a pet, strands of hair could float into the air. Dust will be moved around as well. Although it’s not as severe as the debris from a portable fan, be aware that air conditioning can stir up fine particles in your home.

Air Purification

Fortunately, an air purifier is an easy solution to the above problem. An air purifier cleans the air so you can take a deep breath without the worry about contamination. This filtration often takes place in the AC itself. Filters in your AC catch all of these harmful particles and prevent them from reentering the atmosphere. Once the filter is full, you can simply empty it into a trashcan and pop a new filter in.

Alternatively, you can purchase a separate air purifier that gets the job done on its own. The bottom line is that you can’t always rely on basic solutions such as bottles of air fresheners. These aren’t long term solutions in the first place. It’s in your best interest to invest in a quality HVAC device that will free the air of contaminants.


As the name suggests, HVAC is also responsible for ventilation. Even if the air is perfect inside your home, things can get stale over time. Air that hasn’t been properly circulated can begin to smell and flare up your health conditions. Install ventilators and circulators to freshen up the air inside your home. Within a couple of hours, you’ll notice a massive difference in the air quality. This is a particularly tricky topic because you don’t want to open all your windows when the AC is running. Instead, turn to HVAC appliances that will make the air smell better than ever.

Air Movement

On a similar note, you need to consider how air is moving in and out of the building. Even if all your windows and doors are closed, air naturally flows in and out via cracks and soft surfaces. There’s a big difference between air flowing through the crack in your front door and air flowing through a musty basement to reach your living room. HVAC deals with pipes and airways behind the scenes of your home. When there are natural airways for fresh air to enter, you’ll notice a massive improvement in indoor air quality.


Lastly, pollutants are responsible for decreasing indoor air quality. These pollutants can stem from a number of sources. When you run a gas stove for hours on end, fumes can spread from your kitchen to the rest of your home. When you open up a container of alcohol wipes to clean the counter, pollutants enter the air.

Although the majority of these substances are harmless, they still taint the air in one way or another. HVAC appliances such as humidifiers, dehumidifiers, and air purifiers are excellent for getting rid of these pollutants. You might even have alarms installed that will alert your family if there are toxic gases present in the building.
