What We Fix

Expert service on Japanese and domestic vehicles. We do not service newer European models (BMW, Mercedes, Jaguar).

Signature Service

AC Repair & Recharge

This shop has been Mableton's AC specialist for 35+ years across two owners. We diagnose and repair everything from refrigerant leaks and compressor failures to evaporator core replacements. If your AC isn't blowing cold, we know exactly why — and we fix it right. No guessing, no parts-cannon approach.

Electrical Diagnostics

Mysterious warning lights, intermittent faults, no-start conditions. Electrical problems are where most shops give up — and where we specialize. We use professional-grade scan tools and real component testing to find the actual fault, not just clear the code.

Preventive Maintenance

Oil changes, fluid flushes, belts, hoses, filters — done right with OEM-grade parts. We won't upsell you. If it doesn't need it, we'll tell you. If it does, we'll show you.

General Repair

Brakes, suspension, cooling systems, exhaust, and more. We service Japanese and domestic vehicles only. If another shop told you they can't figure it out — bring it to us.

Vehicle Compatibility
We specialize in Japanese (Toyota, Honda, Nissan, Subaru, Mazda) and domestic (Ford, Chevy, GMC, Dodge) vehicles. We do not service newer BMW, Mercedes, Jaguar, or other European models.

$150 DIAGNOSTIC FEE

We Charge $150 to Diagnose Your Vehicle.
Here's Why That's Good For You.

A lot of shops pretend to diagnose for free — then charge you for the wrong fix. We do it right the first time, and we charge for the expertise that makes that possible.

We run a full scan — not just a code reader
We test components under real conditions, not assumptions
Accurate diagnosis prevents $1,000+ in wrong repairs
We stand behind our findings — in writing

The $150 fee is non-negotiable and required at booking. It applies toward your repair if you proceed with us.

About JW Auto

The Shop Cobb County Mechanics Trust

This location has been Mableton's AC specialist for over 35 years across two owners. John Wanarski took over in 2008 and built the shop's reputation on one thing: solving problems other shops can't.

Other mechanics send John their hardest diagnostic cases. No upsells. No shortcuts. OEM-grade parts only. When you bring your vehicle here, it gets John's full attention — not a rushed assembly line.

What Our Customers Say

100+ reviews on Google · Mableton, Georgia

John figured out an electrical gremlin that two other shops couldn't identify in three weeks. Had it diagnosed in a day, fixed by the next morning. The $150 diagnostic fee is worth every penny.

Marcus T.March 2024

My AC stopped working in July — worst timing. JW Auto had it diagnosed and recharged same week. Been blowing ice cold ever since. This is my shop now.

Sandra R.January 2024

My mechanic actually referred me here when he couldn't solve a no-start issue on my Tacoma. John found the problem in two hours. Straight shooter, no nonsense.
