The HVAC Electrical Parts & Accessories category includes the power, protection and control components that keep residential and light-commercial systems running safely and reliably. From line-voltage feeds and disconnects to low-voltage wiring, contactors and capacitors, every part in this section plays a role in starting motors, switching loads and protecting equipment from faults. Stocking the right electrical parts on your truck reduces callbacks and lets you close out more service calls on the first visit.
Here you’ll find whips & disconnects, wiring & connectors, capacitors & hard-start kits, contactors and relays, electrical wiring & connectors, and transformers matched to common HVAC applications. We focus on field-ready components with durable insulation, UV-resistant jackets, clear terminal markings, secure lugs and properly rated enclosures. Whether you’re replacing a failed contactor, upgrading disconnects for code compliance, or rebuilding a condensing unit’s electrical section, this category provides the parts you need to restore safe operation.
When selecting HVAC electrical parts, always confirm voltage, amperage, phase, temperature rating, enclosure type, wire size and local code requirements. Match contactor coil voltage to the control circuit, verify capacitor µF and voltage rating against the motor nameplate, and size disconnects and whips appropriately for the equipment MCA/MOP values. Use the Compare tools on this page to review ratings, dimensions, connector style and mounting options before ordering.
Pro tip: Before replacing any electrical component, document line and load wiring, breaker size, conductor gauge, equipment nameplate data and any visible heat or corrosion. Take clear photos of the existing layout so you can land wires correctly on the new part and verify that the whip, disconnect, contactor, capacitor and transformer are all properly matched to the system.
