How do I know if it's the alternator or the battery?

A weak battery and a failing alternator can look similar — dimming lights, slow starts, warning lights. Our mechanics test the charging system on-site to confirm which one is actually causing the problem before any work begins.

How long does alternator repair take?

Most alternator replacements take under an hour in your driveway. You’ll get a text when your mechanic is on the way.

Will you give me a price before you start?

Yes. Pick your year, make and model to get a flat, all-in price before booking — no surprise charges after the work is done.

Honestly thought I was looking at a dead battery or an expensive tow truck nightmare when my battery light popped on and the dashboard lights started dancing. Called Angel Mechanic, and instead of losing my entire afternoon at a shop, they fixed the alternator right in my driveway. Clear explanation, transparent pricing, and zero hassle. Saved my week!
