🚗 Diagnosing Catalytic Converter Issues the Right Way At Accomplished Auto, we believe in fixing the root of the problem – not just the symptom. One of the most misunderstood parts of your car’s emissions system is the catalytic converter (or "cat" for short). It plays a critical role in cleaning up the exhaust gases before they exit your vehicle. But when a warning light pops up for something like a “catalyst efficiency” code (P0420 or P0430), it doesn’t always mean the catalytic converter itself has failed. In fact, many times it’s doing its job just fine, and something else upstream – like how your engine is running – is causing the problem. That’s why we take the time to test properly, not just replace parts. 🔍 Why a Prop ... 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
