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 urgent is a failing capacitor or electrical fault in Chattanooga HVAC systems?

Failing capacitors and electrical faults are urgent because they can stall compressors and create fire risk. In Chattanooga's heavy-use months, prompt electrical diagnosis prevents collateral compressor or contactor damage. Request that estimates separate electrical component costs and include safety test results on completion.
