AC components cover the parts that work together to cool the cabin — compressors pressurize refrigerant, condensers and evaporators handle heat exchange, and expansion valves, orifice tubes, and hoses manage flow and pressure through the system. A failing component commonly shows up as warm air from the vents, a compressor that won't engage, a refrigerant leak, or an AC system that blows cold briefly and then fades. Browse replacement compressors, condensers, evaporators, and other AC components for cars, trucks, and SUVs to get cold air blowing again.
