If your A/C isn’t cooling, your heat fades at idle, or you suspect a leak, we diagnose the issue and handle radiator and HVAC repairs to get temperatures back where they should be.
Redi Rad Waterloo is seen as a straightforward, professional shop that focuses on solving the actual problem without pushing unnecessary work. When vehicle comfort or cooling system issues show up—like weak cabin heat when stopped, A/C that won’t hold, or a suspected leak—the approach is to diagnose what’s wrong, explain what’s being done and why, and then complete the repair so the system performs as intended.
We handle everything from minor maintenance to complex mechanical repairs.
We troubleshoot cooling and HVAC problems to identify the specific failure—such as a bad A/C hose or heater-core flow issue—before moving forward with repairs.
When it’s relevant, we handle small but important checks and tasks like leak checks and tire rotation as part of taking care of the vehicle.
Options like shuttle pickup and, when nearby, assistance such as a battery boost help make getting service easier.
Signals are derived from aggregated public customer feedback trends.
