Things to Expect with Indoor Air Quality Testing


The air we breathe can dramatically impact our health. Poor air quality can be a source of aggravation for a range of medical conditions including sinus inflammation, asthma, and allergies. It can also have more dire effects on your health if toxic contaminants, such as mold spores, carbon monoxide, and radon gas are present in your indoor atmosphere.

Therefore, it’s advised that you routinely test the quality of air inside your home to ensure that you’re not exposing yourself to potentially dangerous substances. Fortunately, there are many indoor air quality solutions in North Georgia, that can remedy any issues that may be uncovered during testing. If you’ve noticed the effects of poor air quality in your home or business, you should have your indoor air and HVAC system tested. Read on to learn more about what you can expect during indoor air quality testing in Gainesville, GA.

How are Air Quality Tests Conducted?

While each indoor air quality system in North Georgia, may differ slightly in methodology, there are some common standards that are used. One method for testing indoor air quality is to place the home, office, etc. under negative pressure using large fans. That test is also known as a blower door test and is used to find areas in your home or business where external air may be seeping into your home and impacting air quality. The technicians conducting the air quality test also will need to determine how much air is exchanged in your home and at what frequency air exchange occurs. Finally, sensitive instruments are used to sample the air to identify potential contaminants.

What Pollutants Are Air Quality Tests Seeking?

When technicians conduct indoor air quality tests within your home, they are looking for some of the most common contaminants found in the residential environment. Some of them, such as dust, pollen, pet dander, and dust mites, serve as irritants that can cause bouts of allergy symptoms, sinusitis, asthma, watery eyes, and breathing problems for inhabitants. There are other more harmful substances that will be measured as well, such as radon, volatile organic compounds, black mold spores, and carbon monoxide. Detecting those compounds and discovering their sources is important since the effects of exposure to those substances can seriously impact health and may even be fatal.

What Equipment Is Used?

An array of specialized equipment is used to detect the potential contaminants that can infiltrate your home and degrade the air quality. Photoionization detectors, flame ionization detectors, and summa cannisters are used to sample the air for volatile organic compounds. Tedlar bags and airtight syringes also can be used to gather samples of your indoor air so that they can be examined in detail at a testing facility. Handheld electronic meters that measure carbon dioxide levels and humidity may also be used during the testing process.

What Happens Afterward?

Once your indoor air quality test is conducted, your technician will prepare the samples that were collected. Some tests can be done on-site, though in many cases, the samples are sent to an off-site laboratory where they are examined thoroughly using highly sensitive instruments. Results can take a few weeks. When the results are received by your technician, there will be another consultation to help develop an indoor air quality solution in North Georgia, that meets your needs. Those solutions may include upgraded HEPA filters, sealing off areas of air infiltration, cleaning ducts, or adopting other air purifying equipment as part of your home HVAC system.

If you suspect that your indoor air may be suffering from the presence of pollutants, an indoor air quality test is in order. By identifying the contaminants in your home and isolating their sources, you can prevent them from impacting the health of your family in the future.
