4 Factors Affecting Indoor Air Quality Test Prices

Factors Affecting Indoor Air Quality Test Prices

The cost of air quality testing will depend on the following factors:

1. Specific Type of Air Pollutants to Be Tested

The average cost of basic indoor air quality testing is $400. This typically includes testing for common allergens, mold, VOCs, and carbon monoxide. But, expect to pay more if you want to check for specific types of allergens or pollutants that are not covered in the basic service. Also, this might be needed if you have found alarming levels of contaminants using a DIY home air testing kit.

Specific tests can range from $100 to $1,000+ with an average of $300, depending on the type of pollutant. More extensive analyses will cost more due to more samples that need to be taken and analyzed.

Below is a summary of the testing cost per type of air pollutant (not including removal costs):

Type of PollutantAverage Professional Testing Cost
Mold$300 – $1,000+
Radon$150 – $800+
VOCs$200 – $300+ (per sample)
Asbestos$200 – $1,000+
Home Allergens$100 – $200+
Carbon Monoxide$100 – $200+


Basic home inspections can only identify the presence of mold, not its type and location in your home. A more in-depth mold inspection can range from $300 to $1,000+ but most homeowners pay around $700. Not all types of mold are toxic, but certain varieties like Stachybotrys and Aspergillus can cause serious health complications.

So if you smell something musty or are experiencing mold allergy symptoms but can’t find where the source is, have your home inspected for mold. Once the presence of mold has been confirmed, you need to hire a mold remediation company for complete removal. This can cost around $5,000 for average-sized homes.

Radon is rarely found inside homes but can cause even death due to lung cancer when found. Natural radium and uranium decay in soils and rocks can release radon gas and enter your house through cracks, wall cavities, water supplies, and others. Thus, multiple air samples in different areas need to be taken and tested to locate it which can range from $150 to $800+. The average cost is around $500. As for radon mitigation, you need to pay an additional cost of $700 to $1,200+


VOCs, like formaldehyde which is common in homes, can be found in various household items including paint, cleansers, air fresheners, and others. They can evaporate over time and lead to high concentrations in the air in your home which can cause adverse health effects. Testing for VOCs ranges from $200 to $300+ per sample depending on the type of compound being tested.


Asbestos is common in building materials and don’t usually pose a threat when in good condition. Testing is usually done only when suspected materials are damaged or if you are planning to do anything that would disturb the materials like remodeling.

You can’t see or smell asbestos so you may be unaware that you’re already being exposed to it which can lead to various types of cancer diseases. Thus, asbestos testing is necessary which can cost between $200 and $1,000+ (average of $400+). Once asbestos is found in your home, immediate removal is recommended which typically ranges between $1,000 and $3,000+.

Home Allergens

If you or your family is experiencing specific sensitivities, you need to find out what allergen is causing it through a detailed examination. It can be pollen, dust mites, pet dander, vermin waste, and others. Expect to pay around $100 to $200+.

Carbon Monoxide

Professional carbon monoxide testing can cost from $100 to $200+. But, most homeowners usually have carbon monoxide detectors which can range from $20 to $150+, according to Home Advisor, depending on the detector type.

2. Home Air Quality Inspection Costs Based on Home Size

Another major factor affecting indoor air quality testing prices is the size of your home. Larger houses will obviously cost more because of the larger area to be covered and more samples to be collected. Below are the average air quality inspection costs by home size:

Home Size (Sq. Ft.)Average Cost
< 1,000$200 – $300+
1,000 – 2,500$300 – $500+
> 2,500 $500 – $1,000+
Commercial property$1,000 – $3,000+

3. Cost of DIY Home Air Quality Testing Kits

DIY test kits are inexpensive ways for inspecting the air quality in your home initially and can range from $15 to $200+. This depends on what pollutant you are testing:

Type of PollutantAverage DIY Testing Cost
Mold$30 – $50+
Radon$15 – $30+
VOCs$100 – $150+
Asbestos$100 – $130+
Home Allergens$75 – $100+
Carbon Monoxide$40 – $50+
Formaldehyde$100 – $130+

As for full-analysis kits, they can range from $150 to $500.

NOTE: You still need to seek professional help once your DIY test kit comes up positive for proper remediation or removal of the pollutant.

4. Cost of Air Quality Testing in New Homes or Home Purchases

Testing for indoor air in new homes or new purchases typically ranges from $200 to $1,000+. Construction materials in homes, especially when you’re buying an old house, can release toxic contaminants like asbestos. So before you occupy the house, be sure to have it tested first.

Air quality testing involves testing for indoor pollutants where multiple air, surface, dust, paint, and other samples will be taken from areas of concern. This test aims to determine if the pollutants are at safe levels or not, and if further actions are needed for remediation.

Visual inspection will also be done including the use of testing equipment like sensors and moisture meters to measure ventilation levels, humidity, and temperature. Home systems like vents, ducts, and exhaust fans may also be checked.

After sample collection, the samples will be analyzed in an accredited laboratory in which recommendations can be made based on the findings.

How Long Does Home Air Quality Testing Take?

Indoor air quality inspections can take around one to three hours or more, depending on the size of your home and the number of samples needed. However, you can only get a written report of the results after two to 10 days.
