The starter turns your engine over, and the alternator keeps the battery charged while you drive. When either one fails, your car stops. EZ Swap LLC tests the full starting and charging system and replaces the part that failed.
We test before we replace, because a dead battery, bad cable or loose ground can mimic a bad starter or alternator.

Starter & Alternator Repair in Phoenix Heat
Heat is hard on the starter and alternator. Both sit near hot engine parts, and high under-hood temperatures shorten their life. A failing alternator can also destroy a new battery by undercharging it, so we test the whole system together.
What Affects the Cost
- Whether the part is new or remanufactured
- Vehicle design, since some are easy to reach and others are not
- Related parts such as belts or cables
- Battery condition, which may need replacement too

Starter & Alternator Repair FAQ
How do I know if my alternator is bad?
Signs are a battery warning light, dim or flickering lights, electrical glitches and a car that dies while driving. A charging output test confirms it.
How do I know if my starter is bad?
A single click, grinding or no crank at all with a good battery usually points to the starter.
How long does alternator replacement take?
Many are done in a few hours, depending on the vehicle.
Do you repair or replace?
Usually replace with a quality unit. We will explain the options and give you a quote first.
Can a bad alternator ruin a battery?
Yes. A weak alternator can leave the battery undercharged, shortening its life.
How long does a starter last?
Many last a decade or more, but heat and frequent starts shorten that. Rideshare vehicles start often, which adds wear.
Do you service my make and model?
Yes. We repair all makes and models. Browse our makes and models pages for common problems and recalls by vehicle.
How do I schedule this service?
Call or text (602) 246-9063 with your vehicle and what you need, and we will get you on the schedule.
How long does a car battery last in Arizona?
Heat shortens battery life, and many Phoenix-area batteries last around three years or less, compared with the longer lifespans often quoted for milder climates. Test your battery before every summer, and replace it proactively if it is near the three-year mark or tests weak.
