Electrical components that keep HVAC systems running

MARS® (Motors & Armatures) supplies a wide range of HVAC motors, capacitors, contactors, relays, and electrical components used daily by service technicians. These parts are designed to restore airflow, control power, and resolve common electrical failures quickly.

When diagnosing no-start conditions, weak airflow, or intermittent operation, electrical components are often the root cause. Replacing a failing capacitor, worn contactor, or incorrect motor with the proper MARS equivalent helps prevent repeat callbacks.

Not sure which part you need? Share the equipment model number, voltage, HP, RPM, or the markings on the existing component and we’ll help you match it correctly.

Fast match checklist
Provide: component type (motor/capacitor/contactor), voltage, HP or µF rating, RPM, phase, and equipment model if available.

MARS HVAC Electrical Components — FAQs

How do I match an HVAC motor?

Match voltage, HP, RPM, frame size, rotation, and mounting style. Providing the old motor label makes matching fastest.

When should a capacitor be replaced?

Replace if the measured µF is outside tolerance, the unit won’t start, or you see bulging or leaking on the capacitor case.

Are MARS parts universal replacements?

Many MARS components are designed as universal or cross-reference replacements, but matching electrical ratings is essential.
