Capacitor and Contactor Repair, Diagnosed Before Replaced
A capacitor stores the electrical charge that helps start your compressor and fan motor. A contactor acts as the switch that sends power to the system when your thermostat calls for cooling. When either component fails, your AC may hum without starting, blow warm air, or shut off shortly after turning on.
Our HVAC technicians test capacitors with a meter to verify the correct microfarad rating, inspect contactors for burn marks or pitting, and replace failed components with properly matched parts for your system. The ENERGY STAR program from the U.S. Department of Energy notes that electrical component failures are one of the leading causes of air conditioning breakdowns.
Most repairs are completed in a single visit. A weak capacitor commonly tests at 6 percent or more below its rated microfarad value, and Henderson summer temperatures above 105 degrees speed up that wear over time. Our trucks carry the most common capacitor sizes used in residential AC systems across Henderson, allowing most repairs to be completed during the first appointment.

Signs Your Capacitor or Contactor Is Failing
Capacitor and contactor failures show up in a few clear ways. If you notice any of these, the part is likely the cause.
- AC hums but will not start. The compressor is trying to run but the start capacitor cannot deliver the jolt it needs.
- Outdoor unit shuts off after a few minutes. A weak capacitor lets the motor start but fails to keep it running.
- AC blows warm air. If the outdoor fan or compressor cannot run, the system circulates air without cooling it.
- Clicking sound from the outdoor unit. Often a sign the contactor is sticking or arcing.
- AC stopped working after a power surge. Capacitors are sensitive to voltage spikes from monsoon storms or Henderson grid fluctuations.
- Burn marks on the contactor. Visible pitting or charring means the contact points have worn out and need replacement.
If your AC is showing any of these signs, contact us. A capacitor or contactor is a small part with a big effect on whether your system runs.
