How your vehicle heating and AC system works
Your vehicle heating and AC system works alongside several engine components to control cabin temperature. Compressors, condensers, heater cores, fans, and drive belts all work together to move air and refrigerant so your car stays cool in July and warm in January. When one part develops a problem, you’ll feel it in your airflow, temperature control, and defrost.
That’s where proper diagnostics come in. We find the source of the problem fast so the right repairs get completed before anything else suffers.
