Common questions about Mars OEM replacement parts
Mars capacitors are manufactured to NEMA CP-1 standards with robust metallized polypropylene film dielectric, rated for extended temperature ranges (-40°F to +185°F). Mars tests every capacitor to 110% of rated voltage before shipment. The result is a capacitor that meets or exceeds OEM specifications with a documented service life rating.
Yes. Mars motors are designed as direct-replacement equivalents for OEM condenser fan motors and PSC blower motors used across all major HVAC brands. Mars replacement motors meet or exceed the original OEM electrical specifications and include the same mounting configurations. For best results, match the original motor's HP, voltage, RPM, and frame size.
Mars universal fan blade kits cover the most common OEM blade configurations in 18", 20", 22", 24", and 26" diameters. The adjustable pitch and reversible hub design allows a single Mars kit to replace dozens of different OEM blade configurations. Always verify the blade diameter, pitch angle, hub bore, and rotation direction match your application.
Yes. The Mars Surge Guard and similar voltage spike protection devices help protect HVAC equipment from power surges that can damage control boards and compressors. These are popular upsell items during HVAC tune-ups and replacements.
