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 should homeowners expect for turnaround on capacitor and electrical repairs?

Capacitor and simple electrical repairs are often completed the same day if parts are on the truck. More complex electrical issues or corroded connections may need further work or permits. Describe intermittent starts or buzzing sounds when scheduling. Ask the provider whether trucks carry common capacitors, contactors, and fuses to increase the chance of same-day repair.
