Smog Testing in California: What You Need to Know (And Why Older Cars Need a Special Test)
November 28, 2025
If you live in California, you’ve probably heard about smog tests. The state requires them to help reduce pollution and keep our air clean. But many drivers aren’t sure when they need a smog test, what type of test their car needs, or where to go—especially if they drive an older vehicle.
At Jim Brangham Auto Repair, we make the process simple. And the best part? 👉 We can smog test vehicles older than 1999, which many shops cannot do.
Let’s break it down.
Why California Requires Smog Tests
California has some of the strictest air-quality rules in the country. Smog tests help make sure cars aren’t releasing too much pollution. This keeps the air cleaner for everyone and helps your car run better too.
Most vehicles need a smog check every two years, or when they’re sold to a new owner.
What Makes Older Cars Different?
Cars from 1999 and older need a special type of smog test called a BAR-97 test. This test uses older diagnostic equipment and takes a little more time. Not all auto shops are licensed or equipped to perform this test.
That’s why many drivers with older cars struggle to find a place that can help.
But at Jim Brangham Auto Repair, we are fully certified and equipped to test: ✔ Vehicles from 1999 and older ✔ Cars and trucks that require BAR-97 testing ✔ Most makes and models, including classic vehicles
If your car is older and still running strong, we’re here to keep it road-legal and clean.
What to Expect During Your Smog Test
- When you bring your car to us, here’s what we do:
- Check your vehicle’s emissions system
- Test your tailpipe for pollution levels
- Perform visual and functional checks
- Make sure your car meets California smog standards
The test usually takes 20–30 minutes, and we’ll let you know right away if your car passes or if it needs repairs.
How to Help Your Car Pass
Here are a few quick tips. Make sure your “Check Engine” light is off. Keep up with oil changes and maintenance. Drive your car for at least 15 minutes before the test. Fix any known engine issues ahead of time. These small steps can make a big difference.

Planning a summer road trip? Whether you’re heading out of Cathedral City or just exploring around the Coachella Valley, the last thing you want is car trouble ruining your trip. A little preparation now can save you time, stress, and money later.
Let’s break it down in a simple way. What Does an A/C Compressor Do? The A/C compressor is the heart of your air conditioning system. It pressurizes and circulates refrigerant, which allows your system to remove heat from inside your car and replace it with cool air. When it’s working properly, you get consistent, cold air even on the hottest desert days. Why the California Heat Is Hard on Your A/C System In Cathedral City and the surrounding Coachella Valley, extreme temperatures mean your A/C system is working overtime. That constant use puts extra strain on the compressor and other components. Over time, this can lead to wear, leaks, or complete compressor failure — especially if the system isn’t maintained. Signs Your A/C Compressor May Be Failing Air blowing warm or not as cold as it used to Loud noises when the A/C is turned on A/C clutch not engaging Weak airflow or inconsistent cooling Refrigerant leaks If you notice any of these issues, it’s important to have your system checked before it fails completely — especially during the hottest months. What Causes A/C Compressor Problems? Compressor issues can be caused by: Low refrigerant levels Leaks in the system Electrical problems Worn internal components Lack of regular A/C service Catching these problems early can often prevent a full compressor replacement, which is one of the more expensive A/C repairs. Save Money with Early A/C Service Waiting until your A/C stops working completely can lead to bigger repairs and higher costs. Regular inspections and servicing can help extend the life of your A/C compressor and prevent costly breakdowns. In Cathedral City’s heat, a small issue can quickly turn into a major problem.
