There are many issues that can cause indoor air pollution, and pinpointing the specific materials in circulation in your house can be challenging. While you can visually observe problems like dust and mold in some spaces, these materials can move into hidden spaces, allowing them to affect the air you breathe without being easily detected. Additionally, many particles that pollute your air supply are so small that they can't be seen. Gaseous pollutants are equally hidden from view, posing threats of varied levels based on the material in question. Testing your indoor air quality, however, generally requires the assistance of a trained professional.

Assistance from an HVAC Professional

Since tests of indoor air pollution are significantly affected by heating and cooling system, you'll find that one of the most qualified professionals for assessing air quality is your HVAC contractor. Air sampling can be conducted so that lab analysis provides information about specific irritants. In addition to measuring for gases like carbon monoxide and carbon dioxide, a professional will evaluate levels of mold and mildew in your home's air. Additional gases and pollutants may be targeted based on your area.

Home testing kits can be found in some home improvement stores and departments. However, these are very limited, testing only for specific pollutants and their levels. While you might be able to obtain a mold testing kit or another kit that test for limited bacteria strains, you won't obtain a comprehensive analysis of your home's issues. Because of tight home sealing in today's construction, many household products, construction products and industrial materials contribute to the deterioration of your home's air supply. Better value is gained in enlisting the help of a professional to explore all issues affecting your breathable air.

Equipment Influence on Your Air Supply

Your contractor's assistance is also valuable because adjustments can be made as the testing occurs. For example, an elevated carbon monoxide level in the home may be traced to residue that has collected on venting equipment of combustion equipment like your furnace. Adjustments and cleaning may be helpful in restoring the performance of your system. Your service representative can also inspect your home's venting to determine whether there are problems affecting your air quality. Mold inspection in your HVAC coils and ducts can provide additional information about your home's air. Many contractors offer discounted pricing on testing services in connection with planned maintenance agreements.
