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.

We Test the Capacitor Before We Touch a Wrench

Capacitor and contactor work is electrical, and it should be handled by a licensed HVAC technician with the right meter and the right replacement parts. Pure Plumbing & Air has been repairing AC units across Henderson and the surrounding valley since 2013. Our trucks carry common capacitor and contactor sizes so most jobs are finished in one visit.

We test before we replace. A failed capacitor can be caused by something else in the system, and swapping the part without finding the root cause means another failure soon. Our technicians check voltage, amp draw, and connections so the repair holds. We tell you the cost on the phone before the truck rolls. No surprises at the door. Pure Plan Membership applies discounts on parts.

Licensed HVAC technicians. Nevada contractor licenses #77906 and #88741.
Parts on the truck. Common capacitor sizes (5, 7.5, 10, 35, 40, 45, 55 microfarad) and contactor models stocked for first-visit repairs.
Root cause testing. We check what made the part fail so the repair lasts.
24/7 availability. Capacitor failures often happen in peak heat. We answer the phone.
Henderson climate experience. We know how foothills heat, monsoon storms, and older Sun City Anthem systems affect AC electronics.

Capacitor and Contactor Repair FAQs From Henderson Homeowners

Most capacitors last five to 10 years, but Henderson heat shortens that. Many fail within five to seven years because of the run time and ambient temperatures here.

It depends on the part rating and the unit. We provide a clear estimate before we start. These are among the more affordable AC repairs.

We don’t recommend it. Capacitors store a charge even when the power is off and can deliver a serious shock. The wrong rating can also damage the compressor.

Heat is the main reason. Capacitors are rated for a temperature range, and Henderson summers push them past it. Power surges from monsoon storms also contribute.

Often yes, if the capacitor is the only issue. We test the rest of the system to confirm there isn’t a related problem before we declare the repair complete.

We carry common sizes for residential AC units in the Henderson area. Specialty or oversized capacitors may require a same-week order.

Members get priority scheduling and discounts on repair parts including capacitors and contactors. Preventive checks during membership visits often catch weak capacitors before they fail.

A capacitor stores and releases an electrical charge to start motors. A contactor is an electrical switch that controls when power flows to those motors. The capacitor delivers the energy. The contactor controls the timing. Both can fail and both are common AC repair calls, but they do different jobs and show different symptoms.

Yes. A weak capacitor forces the compressor to draw extra current to start. Over time, this damages the compressor windings and can lead to premature compressor failure. Catching a failing capacitor early is one of the simplest ways to protect the most expensive part of your AC.

Both are quick repairs. A capacitor swap typically takes 15 to 30 minutes once the technician confirms the diagnosis. A contactor swap takes about the same. Most calls finish in under an hour, including testing the system afterward to confirm the repair held.

Customer Testimonials

"We had a water leak and we found Pure Plumbing on the internet with wonderful reviews. I called and now I know why they have great customers reviews. The person who answered the phone was very understanding of our emergency and booked an appointment in the same day. Mike, the technician that came for our issue, was on time, professional and very knowledgeable. He took the time to explain the problem clearly and he fixed it immediately.
