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

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