12.77029 DT Compressor

This thing is basically the heart of your air conditioning system. It takes the refrigerant – that’s the stuff that actually gets cold – and compresses it. Think of squeezing something. When you squeeze it, it gets hotter, then it flows to the condenser where it cools off and becomes a high – pressure liquid. The compressor then sends that liquid to the expansion valve, and the whole cooling cycle starts again. It’s constantly repeating that process to make cold air for your cabin. It’s part of a whole system, obviously, but the compressor is the driving force. It works with the condenser, evaporator, and all the hoses and other components. It’s powered by your engine, usually through a belt. If the compressor isn’t working, none of the other parts can do their job, so you won't get any cold air. It’s a key piece in keeping you comfortable, especially during hot weather. Without a good compressor, your AC is just dead weight. You’ll notice if it’s failing – you’ll get weak airflow, or maybe just warm air blowing. Sometimes you’ll hear some weird noises coming from the engine bay. It's a sealed unit, so it's designed to last a long time, but eventually wear and tear happens. It acts like a shield against the heat, really. Ignoring a failing compressor can also damage other parts of the AC system, so it’s best to get it sorted out when you first see a problem. We carry a good range of these, and you can also find options at places like Fixparts Online, if you want to browse around. DT stands behind its products: Compressor (MPN 12.77029) has a 12-month warranty!
