How to Find the Best Smog Testing in Napa Valley CA 


Smog check stations in Napa County CA must be licensed by the State as protection for consumers.  They are not required by law to have liability insurance; however, all emission testing services bearing The Prime Buyer's Report—TOP 10 symbol do have that liability insurance coverage to reimburse you in the event of any damage to your vehicle, in addition to passing all other requirements for Prime Buyer's Report—TOP 10 status such as our survey phone calls to their previous customers verifying high satisfaction, hiring only documented workers, verified license, clean complaint record, and more.


Smog Tests in Napa County CA
Passing the smog test is important because the California DMV requires owners to present a smog certificate, a document detailing emissions test results, within 90 days of renewing vehicle registration.

Another important aspect of emissions testing in Napa County is whether or not the smog check station can, if your vehicle fails to pass a smog test, fix your vehicle so it can pass the smog test. Smog Test Only stations are prohibited by law from performing diagnosis or repairs of any kind. Others known as Test-and-Repair stations are licensed to perform official smog inspections and smog repairs.

As of January 1 2013, the Gold Shield Smog Check Station program has been replaced by STAR stations. Some STAR smog stations are licensed as test-only and others are licensed to do both smog tests and repairs. Your DMV registration renewal notice might state your vehicle requires a smog check at a STAR station, which makes yours a "directed vehicle" because it has been proactively directed to a STAR certified station. Additionally, vehicles that fail an emissions test at very high emission levels are considered "gross polluters" and then must receive certification specifically from a STAR-certified station.

A Guide To Finding Good Smog Test Centers in Napa County CA 

Step 1: Understand the Rules of Smog Testing in Napa County CA
You may think your car drives exactly the same as it did when you last passed a smog check, but driveability doesn't mean your car will pass a smog test. If your vehicle is fairly new, you don't necessarily need to provide a California smog certificate, but if your vehicle is older, it may not pass smog even though it passed last year. If you are aware of any problems or symptoms that could affect your car's ability to pass a smog check, describe those symptoms clearly and accurately to the smog test technician.

Step 2: Ask & Answer Questions of the Smog Test Stations in Napa County.
The smog center should not only ask about the symptoms, but also your history with the vehicle, any previous problems and even driving habits. Select the most appropriate questions from the list below to supplement what you've already learned. Take notes on the answers you receive.

How long have you been doing smog tests in Napa County?
Do you often do smog tests and/or repairs on my particular model/year of car?
If there is a problem passing the smog test, can you fix the problem once you've found it?
Will you contact the DMV to report my vehicle's smog test results?
When doing repairs, do you use original equipment (OEM) parts, other new parts, or used parts?
Will work performed by your shop affect my manufacturer's warranty?
Will you provide a written, itemized estimate for the smog test and smog repairs?
Will you provide a written contract for the smog test and smog repairs?
What process do you go through to price the smog test and work?
What type of warranty on smog testing and for smog work will you provide?
How long should it take to complete the work?
Do you provide loaner cars while my vehicle is being smogged?
If the smog repair work involves a damaged component, what was the failure?

Step 3: The Preliminary Decision Among Good Smog Testing Stations in Napa County CA.
After you've interviewed good smog check stations in Napa County, narrow the field. Remember that a good smog technician should be working with you to help get your vehicle smogged and registered.

Step 4: Final Research on Smog Test Centers in Napa Valley CA.
Make sure you've got all the information you need before deciding. What credentials do the smog centers have? What about the employees? Does the company have a good reputation? Verify licensing, insurance, and other certifications.

Step 5: The Final Decision on The Best Smog Testing Centers in Napa County For You
Call for any final questions, and if your vehicle will be repaired by the smog station, ask the mechanic to provide a written and signed pricing, timing, quality, and warranty agreement.

Tips About Smog Check Stations in Napa Valley CA 

Don't Smog Test Your Vehicle in Poor Condition.
If your vehicle sputters, stalls, or is otherwise running poorly, don't expect to pass the emissions test. Your inspection fee will be money wasted when the vehicle fails inspection. Repairing any obvious problems with your vehicle before the test will greatly improve your chances of passing your smog test.

Warm Up the Engine Before Your Smog Test.
A warmed-up engine will usually produce better emissions testing results. Internal-combustion engines need time to warm up in order to ensure efficient burning of the fuel in the cylinders. An warmed-up engine running at optimum levels will improve your chances of passing a smog test.

Try Over-the-Counter Products Before Taking Your Car to a Smog Center.
Fuel additives can be an ally in improving engine efficiency and lowering smog levels. Additives can clear carbon deposits and intake and exhaust systems helping fuel and air flow more freely and increasing your chances of passing a smog test.

Perform Some Routine Maintenance Prior to Having a Smog Check.
In certain California counties, enhanced inspections require the smog station to run your vehicle on a dynamometer. Make sure your tires are inflated evenly to recommended pressures to ensure top performance in this section. Also, have an oil change before your test so your engine is running at top efficiency.

Find Out if Your Vehicle Actually Needs a Smog Check.
Every time a vehicle is initially registered, and every two years after that, a smog check is required under California law. This applies to vehicles produced after 1976 that are powered by gasoline, propane, natural gas, and ethanol. Vehicles produced in 1975 or before are exempt from California's emissions laws. Vehicles four or six model-years old or newer are not required to perform a smog check until the vehicle is five or seven years old (unless the vehicle is sold or registered for the first time in California). Other exemptions include: Vehicles with diesel engines, vehicles with two-cycle engines, vehicles with engines smaller than 50 cubic inches of displacement, electric vehicles, and motorcycles, as well as hybrids.

Check Up On The Smog Center.
For all smog checks in Napa Valley CA, be sure to check licensing, liability insurances, and any other relevant credentials before you sign. Understand that "Test Only" smog checks are performed at special facilities that are prohibited from performing repairs.


Keep In Touch With Your Smog Center.
When you have the slightest doubt about how a job is going, ask questions. As the tested vehicle's owner, you have the right to know about all aspects of the emissions testing process. Smog technicians can answer many questions about whether a vehicle will pass, and may be able to offer valuable advice on how to improve your vehicle's performance during a smog check.

Exhaust analyzers found in smog check centers include a two-gas type that measures hydrocarbons and carbon monoxide and a four-gas type, which measures oxygen and carbon dioxide.

  • Exhaust Gas Recirculation (EGR) - An emissions-control system that reduces smog by suppressing the production of nitrogen oxides and diluting the air / fuel mixture with exhaust gas so that cylinder combustion temperatures are lowered.

  • Exhaust Manifold - A component, usually made of cast iron, with passages that carry exhaust gases from exhaust ports to the exhaust system header.

  • Exhaust System - A system including tubing, mufflers, and catalytic converters that directs exhaust gases.
