Indoor Air Quality Testing Costs

A professional indoor air quality test costs an average of $436. Homeowners typically spend between $288 and $586 for the service, depending on the size of their space and the type of analysis they need.

Indoor air quality problems are something that you want to take care of as quickly as possible. Homeowners spend a large percentage of their time in their houses. If there are harmful chemicals or indoor pollution swirling around inside, you and your family will be consistently breathing it in.

Indoor pollution can cause health problems such as allergies, chemical sensitivities, respiratory illnesses and even cancer. Getting your air checked is a smart preventative measure and can help you determine the causes of any indoor pollution, and how to fix it. However, the expense of such an assessment may seem hard to predict.

The first step is to find a reputable professional who can explain the process and what’s included. Inspectors are well-versed in the many facets of air quality issues and can accurately pinpoint areas of concern, where you might miss something important if you do it yourself.

Once you’ve done that, there are a couple of factors that will affect the price of your analysis.

Cost of Air Quality Testing for All Pollutants

A basic whole-home test for all pollutants costs an average of $400. The price can vary depending on the size of your house and the extent of your analysis. Some companies will charge up to $1,000 for thorough services. If you’re concerned about testing for something that isn't included in the basic service, you’ll need to factor in the additional cost of testing for that specific pollutant or allergen.

The more extensive your analysis, the higher the price will be as it will require taking and analyzing more samples. More extensive analysis will also add to consultation time when the results come back.

A whole-home service might include sampling for, or detecting:

  • Mold and Bacteria

  • Volatile organic compounds (VOCs)

  • Allergens

  • Asbestos

  • Radon

  • Combustive Elements

Air Quality Test Cost by Home Size

Home Size in Square FeetAverage Cost
< 1,000$200 - $300
1,000 - 2,500$300 - $500
> 2,500 square feet$500 - $1,000
Commercial Property$1,000 - $3,000+

The size of your house will be a major factor in determining your rate. The inspector will not only take samples of the air, but will also determine the causes, which means more area to search and inspect. They will likely take an air sample from each designated space.

Air Test Costs for New Builds or Home Purchases

It could cost $200 to $1,000 to analyze for contaminants in a new or newly purchased property, depending on the size and your concerns. It's especially important to get these services for newly built houses, as new construction materials could be letting off harmful fumes and chemicals.

Cost of Residential Inspections for Specific Pollutants

Testing for a specific pollutant will cost anywhere from $100 to $1,000, and the average price is $300. Specific analyses are useful when you want to check for a certain allergen or chemical, like radon. Homeowners often request such services after finding high levels of one contaminant or another with a DIY kit, or if they’ve noticed something like mold.

If you’re doing a specified analysis, your expense might be lower. The pro will only sample for the pollutant you’re concerned about. They will be able to diagnose the problem quickly if the results clearly indicate that the pollutant is present.

Asbestos Air Testing

Asbestos air testing costs an average of $500 and will range from $200 to $800 depending on the size of your space and extent of sampling required.

Asbestos is a fiber that was used in building materials until it was discovered to be harmful. If disturbed, it can contaminate the air.

Even if you’re already aware of asbestos in your home and you’re planning to remove it, it helps to check the levels before your removal services. Then, after removal, you’ll want to check again to ensure the contamination is gone. Asbestos removal costs $1,000 to $2,600.

Mold Air Test

Testing for mold costs $300 to $1,000 on average. Many spend around $700 for the service.

Mold and bacteria grow in humid environments and many of them are harmless. However, if it turns out that you have toxic mold in your house, you’ll want to have it removed right away. Three of the most dangerous molds are aspergillus, acremonium and stachybotrys. Mold removal costs about $1,000 to $3,300.

VOC Testing Cost

A sampling and assessment for VOCs costs an average of $200 to $300 per sample, but it varies depending on the type of compound you’re looking for. Formaldehyde is a common VOC in residences.

VOCs are compounds used to make things like paint. They evaporate into the air over time. There are safe and unsafe levels for VOCs. Your professional can help you to find adequate solutions to your issue, such as improving your ventilation system or changing some of the products that you use inside.

Radon Inspection

Professional radon testing costs $150 to $800, with most homeowners spending around $500.

Radon is a gas released by uranium decay in soil which can enter the house through cracks and openings in the foundation. The inspector will likely take samples at multiple points to find the source, and they will likely propose solutions like adding ventilation and installing a suction system to remove the radon. Typically, radon removal methods cost $800 to $1,200.

Carbon Monoxide

Detection services for carbon monoxide could be anywhere from $100 to $200. Many homeowners have carbon monoxide detectors in their houses that can perform this service for them. Carbon monoxide detectors cost $15 to $150, depending on the style.

Other Professional Home Allergen Testing

It could cost $100 to $200 to check for specific allergens that you suspect are in your house. There are many allergens that an expert can check for, and you may need to request these services for your specific sensitivities. Common allergens are:

  • Dust mites (Dermatophagoides pteronyssinus)

  • Pollen (ex: Lolium perenne, Betula verrucosa)

  • Pest particles and waste (ex: Ratus norvegicus, Blatella germanica)

  • Pet dander (ex: Felis domesticus, Canis familiaris)

At-Home Air Inspection Kits

You can buy your own at-home testing kit for anywhere from $15 to $200, depending on the kit you need and the size of your space. A DIY kit will keep your overall price at a minimum.

Keep in mind that, if anything comes up positive, you will need to bring in a professional to help you take care of the problem. Inspectors can diagnose problems from the results with more information and will help you figure out a course of action – something an at-home kit can’t do.

DIY vs. Hiring a Professional Air Quality Testing Company

Overall, though you may not look forward to paying for a professional assessment, it can be a lifesaver in more ways than one.

You can’t put a price on ensuring that you’re not making yourself sick just by sitting in your house. If you hire an inspector, they are more likely to catch all potential environmental hazards, so that you can rest assured that the results are accurate.
