  • AC Repair

    What Makes Our AC Repair “Advanced”
    Many repair shops do not actually offer AC repair. They only offer refrigerant top-off. But low refrigerant is not the only possible problem…what then?
    AC repair At Heavy Hitter’s Performance, we offer “advanced” AC repair because we do two things:
    Listen to you describe the problem you’re having with your AC system—e.g., if the air is not cold enough, if the air circulation is low no matter what the fan setting is, etc.
    When necessary, we run advanced AC diagnostics using the Robinaire system.
    We get to the heart of the problem to provide AC repairs that will both restore your comfort in your cabin and ensure your R134a AC system does not present a threat to the environment.

    Warranty-Backed AC Repair
    The technicians at Heavy Hitter’s Performance are experienced and quality-minded. We take the time to do the job right because your satisfaction and our reputation depend on it.
    We back our work with a 12-month/12,000-mile warranty.
  • Custom Tuning

    What Custom Tuning Can Do For Your Vehicle
    Just about any shop can do routine tuning using updated specifications from your vehicle’s manufacturer. But there are limits to what boxed tuning solutions can do. And there are limits to what “the other guys” can do as far as out-of-the-box engine and transmission tuning.

    pulling trailers
    Everyday driving—a balance of power and torque for optimal drivability
    Everyday driving with extra “oomph” when you need it
    Maximum horsepower and speed

    Maximum fuel efficiency
    You tell us what you want to accomplish, we tweak the tuning specifications to make that happen.
