Why Accomplished Auto Charges for Vehicle Diagnostics (and Why It Saves You Money) If you’ve ever seen a parts store offer a “free code scan” when your check engine light comes on, you might wonder: Why does Accomplished Auto charge for diagnostics? It’s a fair question, and the answer comes down to this: today’s cars are incredibly complex, and getting to the true cause of a problem requires the right tools, training, and time. Proper diagnostics not only protect your wallet but also ensure your car is fixed right the first time. Modern Cars Are Rolling Computers Years ago, a mechanic could pop the hood, listen for a noise, and often figure out what was wrong. But today’s vehicles are more like networks on wheels. Modern cars can have 30–50 onboard computers controlling everything from the engi ... read more

Keep Your Car Breathing Easy in Concord, NH: The Importance of a Clean Engine Air Filter Your vehicle’s engine needs a lot of air to run – in fact, it takes about twelve thousand gallons of air to burn a single gallon of gas. All that air has to be clean for efficient combustion, which is why the engine air filter is so crucial. If your air filter is clogged with dirt and dust, it can’t trap any more particles. The excess dust will bypass the filter and get sucked into your engine’s intake and combustion chamber. Burning dirt and pollen inside your engine does no good (and can even cause wear or damage), not to mention it chokes off the air your engine needs. A clogged air filter can hurt your car’s performance and fuel economy – replacing a dirty filter can improve gas mileage by as much as 10%. In short, a clean air filter helps your engine “breathe” properly, run smoo ... read more

NH Budget Bill Eliminates Vehicle Inspections: How does this impact you! The recent passage of New Hampshire's state budget bill has brought a controversial change: the repeal of mandatory vehicle safety inspections. As of January 30, 2026, annual inspections will no longer be required for most vehicles in the state. While some may celebrate this as a step toward reducing red tape, we at Accomplished Auto believe this decision poses serious risks to public safety, financial stability, and environmental health. This shift is not a panacea. It removes a structured, professional safety check and replaces it with a hope that vehicle owners will self-regulate. It also places more responsibility on police officers, who must now identify unsafe vehicles during routine traffic stops, without the specialized tools or knowledge of trained mechanics. It is important to understand that this repeal does not eliminate any of the existing safety or emi ... read more

As the summer heat sets in, there’s nothing more frustrating than turning on your vehicle’s air conditioner and realizing…it’s not blowing cold air. At Accomplished Auto in Concord, NH, we hear this question all the time. The good news? You’re not alone—and we’re here to help. Understanding the A/C System Basics Your vehicle’s air conditioning (A/C) system relies on refrigerant—a gas that circulates through components like the compressor, condenser, and evaporator—to create cool air. But a number of issues can disrupt this system. Let’s break down the most common culprits. 1. Refrigerant Leaks: The Most Common Problem The A/C system must be completely sealed to function correctly. Unfortunately, small leaks in hoses, seals, or couplers can allow refrigerant to escape. Even a pinhole can cause enough loss over time to prevent the system from cooling. Federal law requ ... read more
