As you might know, a vacuum pump is a piece of equipment that allows us to vacuum dust, dirt, pollen grains etc. at our homes and offices. Similarly, an automotive ac vacuum pump pulls a vacuum on your car’s ac system. Usually, this equipment is quite simple to use and fairly inexpensive. First, you need to turn off your car’s conditioner as well as the engine. In case of an automotive ac vacuum pump, you don’t connect the pump to the ac system. You connect a refrigerant gauge’s middle port to the low pressure port of the car’s ac system. Once you are all set, you can use the vacuum pump.
There are several uses of an automotive ac vacuum pump. The most important use, however, is removal of air and moisture from your car’s ac system. Now, as you might know, moisture can be fatal to your car’s air conditioning system. This is because when moisture gets mixed with the refrigerants in automobile’s ac system, the mixture becomes very corrosive. The problem is that just like a slow leak in tires, the corrosion caused by the mixture is noticeable only when the damage is already done. An ac vacuum pump takes care of all these problems by creating a vacuum in the car’s air conditioning system. What it does is that the low pressure created due to the vacuuming boils off the moisture, at quite low temperatures. Once the moisture becomes vapor, it is vented out through the air conditioning system.
Now, when you are planning to buy a new automotive ac vacuum pump, there are few important points that one should keep in mind. Usually, there are two types of ac vacuum pumps. One is the heavy ac vacuum pump that is used for heavy vehicles like trucks and other commercial vehicles. The other type is much lighter, easy to carry around and simpler to operate. The problem with an ac vacuum pump built for domestic use is that it usually does not pull as good a vacuum as you would like. It has been seen that the domestic automotive ac vacuum pump is not very efficient in boiling off much moisture from the car’s ac system. Of course, there is no denial that the best and most effective ac vacuum pump is the one you will find being used by your favorite garage’s mechanic. To determine how much air volume the ac vacuum pump can remove from the automobile’s ac system, check the CFM rating on the box of the ac vacuum pump. It is quite obvious that the more air an ac vacuum pump can remove, the faster the work will get done.
Apart from buying the ac vacuum pump in the same traditional way, that is, from retail stores, you can also look at purchasing from online stores. Of course, the online store must be one with high reputation. I usually prefer Amazon. These people have been in this business for a long time; they are also reliable and trustworthy. Moreover, what’s better than saving few dollars through discounts offered by them? You can get ac vacuum pump from several popular brands at Amazon. Few of these brands are Robinair, Mastercool, Interdynamics, FJC, Powerbuilt, and many more. The price ranges anything from eighty five dollars to around three thousand dollars. So, depending upon your requirements and budget, you can choose the best ac vacuum pump for your car. Amazon ensures security of your banking details and their shipment is safe too. These pumps can last few years but from warranty point of view, most of them come with one year manufacturer’s warranty.
While researching about functions, performance and other details of an ac vacuum pump, I came across few issues that some of the customers have reported while giving reviews. However, I must say that the comments are not such that would stop or discourage anyone to buy an ac vacuum pump for his car. For instance, one customer on Amazon reported that sometimes, the oil from his ac vacuum pump leaks. So every time before using the pump, he has to ensure that it has oil. It must be noted that the customer mentioned that he is waiting for all the oil to be used or leaked out, so he can find the leak and fix it. Another customer said that the finishing of his ac vacuum pump appears cheap, but agreed that for the low cost, he got the best value for his money, so you will need to decide what is most important for you.
Overall, buying a good ac vacuum pump for your automobile’s air conditioning system will keep the system well functioning for several years.
