When it comes to car air conditioning, there are a few things you need to know in order to make sure your compressor is working properly. The first is the compressor’s type. A lot of compressors are made with three types of blades- the blade type, the centrifugal type, and the direct drive type. The blade type compressors are usually more reliable and can last longer than other types. However, they can be more expensive to buy. The centrifugal type compressors are usually less reliable but can last for a longer time than the blade type compressors. They also have a higher speed which makes them better for larger areas or for applications that require high speeds. Direct drive compressors are the best choice if you have a lot of space or if you need high speeds for a specific application. They’re also the most expensive option but they’re usually the most reliable.
