Air Team operates an emissions testing station at Bedford Park
Air Team Vehicle Emissions Testing Station is located in Bedford Park and performs state-mandated emissions tests on passenger vehicles. The station tests whether your vehicle meets current pollution standards for nitrogen oxides, particulate matter, and other regulated emissions. If your vehicle passes, you receive a certificate valid for two years; if it fails, the station provides a report showing which systems need repair.
Bedford Park is in Cook County, Illinois, which means your vehicle must pass an Illinois emissions test before you can renew your registration. Air Team is one of several hundred authorized testing stations across the state. The station operates on a walk-in basis during posted hours — you do not need an appointment, though wait times vary by time of day and season.
The test itself takes 10 to 20 minutes and costs a flat fee set by the state, currently around $30 for most vehicles. You will need your vehicle keys, your registration or proof of ownership, and a valid photo ID. Bring your vehicle with a full fuel tank or close to it, because the test requires the engine to be warm and running.

What happens during the emissions test at Air Team
When you arrive, staff will check your registration and vehicle identification number against the state database to confirm your vehicle is due for testing. They will ask you to drive onto the dynamometer — a machine with rollers that measures how much pollution your vehicle produces under simulated driving conditions. The test runs your engine through a series of speeds while sensors measure exhaust output.
During the test, your vehicle must stay within a narrow range of engine speed and load. If your vehicle stalls, surges, or cannot maintain the required conditions, the test fails automatically. This does not mean your emissions are too high; it means the test could not complete. You can return and try again after the problem is fixed.
After the dynamometer portion, a technician performs a visual inspection of your emissions control equipment — the catalytic converter, oxygen sensors, and related components. They check that nothing is missing, disconnected, or obviously damaged. If both the dynamometer test and visual inspection pass, you receive your certificate when ready.
Reasons vehicles fail the emissions test
The most common failure is a malfunctioning oxygen sensor or catalytic converter. These parts regulate how much fuel burns in the engine and how much pollution escapes the exhaust. When they fail, nitrogen oxide and particulate emissions rise above the legal limit. A failing check engine light often indicates one of these problems, though not always.
Vehicles with very high mileage, poor maintenance history, or recent engine problems are more likely to fail. Diesel vehicles and vehicles manufactured before 2000 have different test standards than newer gasoline cars, so do not assume your vehicle will fail just because it is older. The test is designed to catch vehicles that genuinely pollute above the legal threshold, not to fail cars straightforward for age.
If your vehicle fails, the report will specify which pollutants exceeded the limit — usually oxides of nitrogen, carbon monoxide, or hydrocarbons. This information helps a mechanic know which systems to inspect. You can return to Air Team after repairs and retest at no additional charge within a certain window, typically 30 days.
How to prepare your vehicle before testing
Drive your vehicle for at least 20 minutes before arriving at Air Team so the engine reaches normal operating temperature. A cold engine produces different emissions readings than a warm one, and the test requires the engine to be at temperature. If you arrive with a cold engine, staff may ask you to wait or may refuse to test until the engine warms up.
Make sure your fuel tank is at least three-quarters full. The test requires fuel pressure to be stable, and a nearly empty tank can cause pressure fluctuations that make the test fail. Check that your gas cap is tight and not cracked; a loose or damaged cap triggers a visual inspection failure in many cases.
If your check engine light is on, have a mechanic read the code before testing. Some codes indicate emissions control problems that will cause a test failure; others do not. Knowing what the code means lets you decide whether to repair before testing or test first and use the results to guide repairs.
What to bring and what the test costs
Bring your vehicle registration or proof of ownership, a valid photo ID, and your vehicle keys. Air Team staff will record your vehicle identification number and mileage. If you do not have your registration with you, some stations will look up your vehicle in the state system using your driver's license number and vehicle information, but it is faster to bring the registration.
The test fee is set by the Illinois EPA and does not vary between stations. As of 2024, the fee is approximately $30 for most passenger vehicles. Hybrid vehicles and electric vehicles have different testing procedures and may have different fees; call Air Team ahead if you drive one of these to confirm the fee and whether they perform that test.
Payment methods vary by station. Most accept cash and card, but call ahead to confirm. If your vehicle fails and you return for a retest after repairs, you typically pay the full fee again, though some stations offer a reduced retest fee within a short window.
Finding Air Team's location and hours at Bedford Park
Air Team's exact address and hours are listed on the Illinois EPA website under "Authorized Emissions Testing Stations." You can search by ZIP code or station name. The station's hours may vary by season; many testing stations reduce hours in winter or close for holidays. Call ahead to confirm they are open before driving to Bedford Park.
The station operates on a walk-in basis, so you do not need to schedule in advance. However, wait times can be 30 minutes to an hour during peak times, typically late afternoon on weekdays and Saturday mornings. If you want to minimize wait time, arrive early in the morning on a weekday or mid-afternoon on a Tuesday or Wednesday.
If Air Team is closed or has a long wait, other authorized stations operate throughout Cook County. The Illinois EPA website lists all stations with their hours and contact information. You can test at any authorized station; your vehicle does not have to be tested at a specific location.
What to do if your vehicle fails the test
When your vehicle fails, Air Team provides a printed report showing which emissions exceeded the legal limit and by how much. Take this report to a mechanic and explain which pollutants were high. The mechanic can use this information to focus on the most likely problem areas — usually the oxygen sensor, catalytic converter, or fuel injection system.
You have a set period, usually 30 days, to make repairs and return for a retest. Some stations charge a reduced fee for retests within this window; others charge the full fee. Ask Air Team about their retest policy when you receive your failure report.
If repairs are expensive and your vehicle is old, you may want to explore whether your state offers a vehicle repair information program or a vehicle replacement program for low-income drivers. These programs vary by state and are not available everywhere, but they can help offset repair costs. Contact your local air quality agency or your county social services office to ask whether such programs exist in your area.
Frequently Asked Questions
Can I test my vehicle if the check engine light is on?
Yes, you can test with the light on. However, the light usually indicates a problem that will cause a test failure. It is often cheaper to have a mechanic read the code first — many shops do this for free — so you know whether the problem affects emissions before paying for the test.
What if my vehicle stalls or surges during the test?
The test will fail if your vehicle cannot maintain the required engine speed and load. This is not a final result; it means the test could not complete. You can return after the problem is fixed. Common causes are a dirty fuel filter, failing fuel pump, or vacuum leak.
How long is the emissions certificate valid?
An Illinois emissions certificate is valid for two years from the date of issue. You must renew your vehicle registration before the certificate expires, or you cannot legally drive the vehicle. You can test up to 90 days before your current certificate expires and use the new one when ready.
Do I have to test at Air Team, or can I go to another station?
You can test at any authorized Illinois emissions testing station. Air Team is one option, but if their wait time is long or their hours do not work for you, other stations in Cook County perform the same test. Your vehicle does not have to be tested at a specific location.
What if I just bought a used vehicle and do not have a registration yet?
You will need to register the vehicle with the Illinois Secretary of State before you can test it. The registration process requires proof of ownership, proof of insurance, and payment of registration fees. Once you have a registration, you can test at Air Team or any other authorized station.
