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.

What signs indicate an electrical problem like a failed capacitor that Raleigh technicians commonly repair?

Immediate failure signs include noisy startups, humming without cooling, and intermittent compressor cycling. Technicians typically test start/run capacitors, contactors, and wiring before replacing parts. Ask whether the provider performs voltage measurements and motor amp draw tests. Proper electrical diagnosis reduces unnecessary part swaps and speeds accurate repair during peak summer demand.
