Indoor Air Quality: Why You Should Have Your Home Tested

December 18, 2023

Most of us never stop to consider how the air in our home differs from the fresh air we breathe when we step outside. While it may be hard to believe, the truth is that the quality of the air inside our homes is often much worse than the air outside of it. 

Even with a high-quality air conditioner and additional filtration systems, monitoring the air quality indoors can be a difficult job that requires insight from a trained and certified professional. Without proper guidance, you can be setting yourself and your family up for a wide range of health issues resulting from poor air quality before you even identify the source of the problem.

In this article, we’ll guide you through everything you need to know about indoor air quality testing so that you can make informed decisions about the well-being of your family, including signs of poor air quality, what to look for in an inspection, and more. 

Signs Of Poor Air Quality In Your Home

One of the most significant issues with monitoring indoor air quality is that it can be difficult for most of us to identify the signs of a problem. However, there are a few symptoms you can look out for that can help you determine if the air quality in your home is becoming a source of concern. 

Musty or Foul Smells

Ever noticed a strange, musky aroma in your home but couldn’t find the source? Your overall air quality could easily be to blame. In many cases, these odors are actually caused by mold and other particles that are lingering in the air, which will need to be addressed by an air quality expert fast. 


Beyond your sense of smell, you can also identify air quality issues by paying attention to other physical symptoms. Headaches, for example, can be an indicator that unseen particles are causing irritation in your home. 


Another physical symptom of poor indoor air quality is coughing, which is usually due to the presence of allergens, mold, and other unwanted particles in the air. This type of cough will be persistent and may not respond to traditional cold and flu remedies. 


The easier it is to breathe, the easier it is to energize our bodies. Without good quality air, you could find yourself becoming lethargic or tired more quickly than before, even if your lifestyle has remained the same. 

Sleep Disturbances

Conversely, you might also find yourself waking up more frequently during the night. This could be a sign that your body is attempting to warn about the presence of harmful particles in the air. 

Itchy Sinuses

When allergens aren’t being filtered out of your home effectively, the result can lead to itchy sinuses, watery eyes, and other common symptoms of an allergic reaction. 

Weakened Immune System

Finally, if you or someone in your family suffers from chronic health issues, poor air quality in your home can cause their symptoms to worsen or even render their treatments ineffective. This can lead to devasting consequences if not handled quickly and appropriately by a trained professional. 

When To Have Your Indoor Air Quality Tested

Of course, even with all of these signs in mind, there may be times when identifying an air quality issue in your home is nearly impossible without the insights from a reliable indoor air quality test. That’s why we recommend having a test performed when any of the following circumstances occur:

After Water Damage

Water damage is a nightmare for any homeowner, whether you’re dealing with minor flooding or a more severe situation. Along with causing substantial damage to your home’s structure, water damage can also leave behind mold and other harmful particles, which greatly impact your indoor air quality. We suggest having your air quality tested anytime you’ve encountered water damage in your home, regardless of how small the damage may appear. 


Preparing your home for the arrival of a newborn is an exciting yet often stressful time. Since infants have naturally more vulnerable immune systems, it’s a good idea to have the air quality in your home tested while you’re expecting, ensuring that Mom and baby can breathe easily. 

Spray Foam Insulation

Using spray foam insulation has many benefits, especially when you’re looking to increase the energy efficiency of your home. Unfortunately, there are some downsides to these types of insulations, particularly when it comes to air quality. Spray foam is known to trap particles in your home rather than allowing them to be filtered back outside. If you know you have this type of insulation on your property, having your home tested regularly is a good idea. 


As we’ve mentioned, poor air quality can be a major health concern for anyone with a weakened immune system. If you’ve recently been hospitalized or undergone surgery, ensuring good air quality in your home can help you recover more effectively and have you feeling like your usual, healthy self again in no time. 

Seasonal Changes

It’s no secret that seasonal allergies vary throughout the year, which is why we suggest having your indoor air quality tested as the seasons change. This can help lessen the impact of outdoor allergens entering your home and reduce the irritations that come with these fluctuations. 

How Does Indoor Air Quality Testing Work?

Now, it’s important to keep in mind that there are a LOT of companies that claim to offer indoor air quality testing services but lack the accreditations and expertise to perform these tests effectively. Before you choose a company for your air quality testing needs, it’s a good idea to familiarize yourself with the key parameters that are required for a comprehensive indoor air quality test. 

Moisture and Mold Screening

First and foremost, moisture and mold are a top contributor to poor air quality in residential homes. Mold produces dangerous spores and can linger in the air when left untreated, which is why mold testing is a crucial component of an air quality test. 

Ultrafine Particulates (PM)

There are many types of fine particles that can impact the air quality in your home, but the most common are PM 2.5 and PM 10. Testing for these specific particles is essential to understanding the overall air quality in any space. 

Volatile Organic Compounds

Volatile organic compounds, or VOC, are particles that are emitted from many everyday household items, including cleaning products, paints, and other furnishings. Typically, these VOCs are filtered out through your ventilation system but still need to be tested to ensure good air quality. 


Formaldehyde is present in a wide range of commercial and residential building materials, and it is relatively harmless at low levels. However, if high levels are present in your home, this can lead to serious health issues for your family. 

Carbon Dioxide

Most of us are well aware that carbon dioxide is highly hazardous at high levels, but in reality, even low levels of this gas can be dangerous in your home. A good indoor air quality test will be able to detect when the carbon dioxide levels in your home have become higher than they should. 

Carbon Monoxide

Similar to carbon dioxide, carbon monoxide is another colorless, odorless gas that is dangerous to humans when inhaled at high levels. In fact, carbon monoxide poisoning can be lethal within a matter of minutes, which is why testing for this substance is critical in your home.

Common allergens can range from outdoor pollen to dander from our furry family members and are usually filtered out through your home’s ventilation system. Unfortunately, these allergens can also build up when your home is not being filtered correctly, causing increased allergic reactions for you and your family. 


Radon is a highly harmful gas that seeps up through the soil and into your home. When radon levels become too high, it can lead to a wide range of health concerns. Testing for radon is an essential aspect of an indoor air quality test, especially if you have family members who already suffer from chronic health issues. 


Electronic magnetic fields, or EMF, occur when radiation from power lines, cell phone towers, and other electronic broadcast centers is transmitted into the area around them. While many air quality testing companies don’t offer EMF analysis, more homeowners are becoming concerned about the health implications of being exposed to these fields, and an increase in EMF testing will become more and more crucial as time goes on.

Noxious Gases

Lastly, noxious gases are a type of gas that is considered to be highly toxic when inhaled. The most common noxious gases include NOx, SO2, H2S, and NH3, and all of these should be included in your indoor air quality test.
