Frequently Asked Questions


  • How often should I service my vehicle's AC system?

    We recommend having your air conditioning system inspected annually before summer weather arrives. This preventive maintenance helps identify potential problems before they leave you without cooling during Wisconsin's hottest days.

  • Why is my car's heater blowing cold air?

    Cold air from your heater typically indicates low coolant levels, a faulty thermostat, or heater core problems. Our diagnostic testing quickly identifies the specific cause and provides targeted repair solutions.

  • How much does automotive AC repair cost in West Bend?

    AC repair costs vary depending on the specific problem and required parts. We provide transparent estimates before beginning any work, and our competitive pricing makes quality climate control repair affordable for all budgets.

  • Can you repair AC systems in older vehicles?

    Yes, our experienced technicians service climate control systems in vehicles of all ages. We have access to parts for older vehicles and can often repair systems that other shops might consider unrepairable.

  • How long do AC and heating repairs typically take?

    Most climate control repairs are completed within the same day. Complex repairs requiring special-order parts may take longer, but we'll provide a clear timeline and keep you informed throughout the process.

  • Do you offer emergency AC repair during heat waves?

    While we don't offer emergency AC service, we understand the urgency of climate control problems during extreme weather. We prioritize these repairs and often accommodate same-day service for urgent situations.

    Our comprehensive 5-year/50,000-mile warranty covers parts and labor for all climate control repairs. This industry-leading warranty demonstrates our confidence in our work and provides long-term protection for your investment.

  • Can a failing AC system damage my engine?

    Yes, AC system problems can sometimes affect engine performance, especially if the compressor seizes or refrigerant leaks onto other components. Prompt repair prevents more expensive engine damage.

  • How do I know if my cabin air filter needs replacement?

    Reduced airflow, musty odors, or increased dust in your vehicle often indicate a dirty cabin air filter. We inspect and replace cabin air filters as part of our comprehensive HVAC service.

  • Do you service hybrid and electric vehicle climate control systems?

    Absolutely. Our technicians are trained on the unique HVAC systems found in hybrid and electric vehicles. We have the specialized equipment and knowledge needed to safely service these advanced climate control systems.
