What People Say About Us

Unmatched Customer Service: Real Feedback from Satisfied Clients

"We were having an 'issue' with our ac and after a thorough evaluation, the gentleman at Sims kindly informed us there was nothing wrong with the ac except the button was not on. Even though we were the dumb ones, these guys were so nice and honest and didn't speak down to us. They did not even charge us for our mistake. I can't say how much we appreciate their kindness, honesty, time and professionalism."

by Michelle Thaxton

"Anthony and the team were extremely helpful! Had the run around with some other businesses in Killeen and they squared me away in less than a day! Great service, very reasonable pricing, super understanding and helpful."

by Haley

"Highly recommended!!  Did great work on my daughters car diagnosed it and replaced it and found that the part was faulty and replaced it again all in the same day also checked my ac only to tell me it was fine and didn’t need replacing. Most shops would have changed it anyway. Talk about integrity. This is our new shop!!"

Auto Repair FAQs

  • When should you stop putting money into a car?

    You should stop putting money into a car when repair costs exceed its market value. If the car frequently breakdowns or you constantly have to pay for auto repairs, then it's probably time to replace it.

  • How should you shop around for auto repairs?

    If we were shopping around for auto repairs, we would do the following:

    • ask for auto repair shop recommendations from friends and family
    • look at online reviews
    • compare prices and services from multiple auto repair shops
    • visit the shops and ask about warranties

  • Do you accept walk-ins?

    Yes. It's best though to book an appointment online or call us directly to discuss when we can work on your vehicle.
