Why did my AC stop cooling but the fan won't start?

A failed run capacitor or contactor is the single most common cause — both are low-cost parts, and a measured diagnosis confirms which one before anything is replaced. Watch out for a shop that jumps straight to 'your compressor is dead' without testing the cheap electrical parts first.

How much should a capacitor or contactor replacement cost?

The parts are inexpensive; the service call and labor make up most of the bill. An honest shop diagnoses the specific failed component and prices it directly, rather than bundling it into a vague 'electrical repair' or using it as a lead-in to sell a new system.

How can homeowners spot electrical capacitor or contactor problems versus a failing compressor?

Start with basic signs: repeated short cycling, slow or noisy motor starts, or a unit that runs briefly then stops. These suggest capacitor or contactor faults. A qualified technician performs voltage and amp tests to differentiate electrical issues from compressor failure before recommending replacements.
