In this episode, we break down the four most critical components of a residential air conditioning system—the parts that must be working properly for your AC to cool efficiently and reliably.

We cover:

The Compressor – the heart of the system and how we verify it’s actually pumping refrigerant

The Condenser Fan Motor – why airflow across the coil matters and what happens when it fails

The Capacitor – what it does, why it fails so often, and how we properly test it

The Contactor – the electrical gatekeeper that tells your system when to turn on and off

We also walk through how a professional technician checks each component, what tools are used, what warning signs homeowners should pay attention to, and how catching issues early can prevent expensive breakdowns.

Whether you’re a homeowner who wants to understand what’s being inspected during a service call—or a newer technician looking to sharpen the fundamentals—this episode gives you a practical, real-world look at AC diagnostics without the fluff.

🎧 Tune in and get confident about what’s actually happening inside your AC system.
