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 capacitor or other electrical component failure in Mount Pleasant homes?

Common signs are intermittent compressor starts, humming noises, and unit failure to power on. Coastal humidity and corrosion raise electrical failure risk. Request a written electrical diagnosis and parts warranty before work begins.
