At Harrison Automotive Repair, we help our Louisburg customers' cars run as cleanly and efficiently as they possibly can. We provide a range of emissions testing services to ensure that your car is running and driving its best, as well as complying with all local smog regulations. Should a problem arise with any of your vehicle's emission systems, we provide the parts and expertise to get you back on the road. Harrison Automotive Repair can replace mufflers/catalytic converters, refill diesel exhaust fluid, and make sure the full range of filters in your vehicle's exhaust system are working perfectly.

Regulators understand that older cars simply can't meet modern emissions standards without extensive modifications. For newer cars however, passing a smog test is a requirement of road legality. Call us at 919-831-0208 to learn more about the emissions requirements for your vehicle.

Emissions testing (also known as smog testing) is a vital part of the maintenance of your vehicle. E-tests provide your mechanic with important information about your car's engine and exhaust system. If important components, like your car's catalytic converter aren't working properly, the car isn't running as it was intended to by the manufacturer. Inefficiency costs you extra money in fuel and does unnecessary harm to the planet. Emissions testing can also affect the value of a vehicle you're trying to sell; while you can still sell a car without a valid e-test certification, you'll get more money for one that has passed the test.

There are several reasons that a car may fail its emissions test. There may be a problem with the vehicle's fuel system adding too much fuel to the air-fuel ratio required for proper combustion within the cylinders of the car's engine. This is known as "running rich" and results in the smell of gasoline from fuel passing through the engine and exhaust system without being fully burnt. Causes of this issue range from faulty fuel injectors to issues with the engine's control computer. There may also be problems with oxygen sensors or the vehicle's ignition system. At Harrison Automotive Repair, we use a complete set of diagnostic equipment to determine the problem and fix it quickly, explaining every step of the process to you, our valued patron. Call us at 919-831-0208 or send us an email to arrange a health check for your car's emissions system today!

We have trusted and valued Harrisons with a number of Volvos over the years. We refer to Andy as the "Volvo Whisperer". Andy and his crew have breathed new life into old cars and evaluated ones we were thinking about buying. He has never let us down, has tremendous expertise, and awesome ethics. We (I am speaking for my family, also) give our highest recommendation to Andy and his crew. Once, I presented a car for service and described an unfamiliar noise it was making. Andy verbalized the noice and knew exactly what the problem was and how to fix it. Andy is honest and charges fair prices and has our highest regards.quotes-image
