Should I Get an Air Quality Test for My Home?

National Refrigeration explains why having your indoor air quality tested can give you peace of mind or identify pollutants that need to be filtered out of your home.

Indoor air quality is not always a top concern for individuals unless they suffer from asthma or allergies. Yet, according to the EPA, indoor air can be 2-5 times more polluted than outdoor air. Due to this statistic, as well as an increased concern since the pandemic, having your indoor air  quality tested can give you peace of mind or identify pollutants that need to be filtered out of your home. 

There are three types of tests performed when you hire a professional to assess your home’s air quality for pollutants and other irritants. These three tests are:

A biological air quality test measures the levels of irritants such as mold, pollen, dust mites, bacteria, and dander.


This test measures the levels of irritants such as mold, pollen, dust mites, bacteria, and dander. The above mentioned particles can build up over time in ductwork and vents. Your specialist can help you determine the best solution for eliminating these irritants and improving the overall airflow.  A biological air quality test is especially beneficial if you suffer from respiratory ailments such as asthma.

Chemical or Volatile Organic Compounds (VOC):

This test will measure the levels of compounds like formaldehyde, lead and Radon. If your home has any leaks, such as cracks in the foundation, this test will help locate the affected area so you can fix the issue at the source. Chemicals and compounds such as these can lead to a variety of health risks. Some symptoms include irritation to the eyes, nose, and throat; headaches and loss of coordination; nausea; and damage to the liver, kidneys, or central nervous system.

Combustion Pollutant:

This test measures combustion pollutants including carbon dioxide, nitrogen dioxide, fine and ultrafine particles, polycyclic aromatic hydrocarbons, and formaldehyde. Even a tiny amount of these pollutants can be extremely harmful and sometimes fatal.

There are various solutions depending upon your specific indoor air quality needs or issues: 

Make sure your family isn't breathing in harmful bacteria, viruses or other pollutants.

Cold Plasma Generator: 

We recommend Phenomenal Aire’s Cold Plasma Generator. Installed in your ductwork, this device “scrubs” the inside air to reduce floating particles. 

Air Cleaners: 

The quickest and most inexpensive way to improve your air quality and filter out bacteria, viruses, pollen, animal dander and other pollutants. 


Whole-house humidifiers blow moisture directly into ductwork to maintain proper humidity levels during the dry seasons. Helping to alleviate static electricity, dry skin, lips, noses and scratchy throats. Humidifiers are especially useful during the dry winter months. 


Controlling humidity is important for comfort levels but also to prevent damp conditions which can lead to mold growth. Whole-house dehumidifiers can keep your air cool and dry during the hot and humid New England summers. 


Effective ventilators control mold, dampness and exposure to hazardous fumes. 

UV Lamps: 

UV lamps kill organisms that grow on the indoor coils of your cooling system.
