In your vehicle, the automotive air conditioning compressor has the simple task of moving gas between the condenser and the evaporator. However, it is often considered to be the heart of the system and if this belt-driven piece of equipment fails to do its job, the entire system quits functioning as designed.

The automotive air conditioning compressor is typically attached to the engine of your vehicle and is belt driven. One of the primary causes of a failed automotive air conditioning compressor is a loose or broken belt as a loose belt may not operate the compressor properly causing lowered pressure in the system and the gas is not transferred to the system’s other components efficiently. Similar to the air conditioner in your home or office, the vehicle’s system has three main components, the automotive air conditioning compressor, a condenser and an evaporator.

The vehicles closed system contains Freon gas and the automotive air conditioning compressor pressurizes the gas, which converts it to hot, high-pressure gas and forces it into the condenser, which looks similar to the radiator in your car, to dissipate the heat condensing the hot, pressurized gas into a liquid. As it is forced through an expansion valve it evaporates into cold, low-pressure Freon gas.

Air Exchanged Inside The Vehicle

The cold gas, typically around 32-degrees, then is passed through coils in the evaporator inside the vehicle. A fan blowing across the coils sends the chilled air into the vehicle and the gas absorbs heat from inside and sends it back through the automotive air conditioning compressor to start the cycle all over again. Small leaks can cause the unintended escape of gas, which will also cause the system to work inefficiently.

Many times when the vehicle’s air conditioner is in use, there will be water dripping from the condenser’s drain visible under the vehicle, which is perfectly normal. The window air conditioning units in the house will also allow condensed water to drip to the ground and is a natural part of the unit’s operation.

Similar to the home units, if an automotive air conditioning compressor is operated when outside temperatures are below about 60-dedgrees, ice can build up on the coils, which renders the units ability to cool the inside air ineffective. Simply turning the unit off until the ice melts will restore its function. The gas running through the automotive air conditioning compressor usually has a small amount of oil included to help maintain proper lubrication inside the compressor.

Credit card rewards have been around for quite some time now and they are quite popular. There are many to choose from and one of the newest is automotive credit cards. These cards pair automotive manufacturers with a major credit card company. A person earns rewards towards the purchase of their next vehicle or other products from the manufacturer by using their automotive credit card.

Each automotive credit card is different and their reward programs work differently. So if a person does not have their heart set on a particular manufacturer they are best to shop around. There are also cards that now have rewards that work for any manufacturer, which may be best for an indecisive person or someone who is not sure what make of vehicle they would like to buy. Some automotive credit cards do not offer rewards towards vehicle purchases, instead they offer rewards towards the purchase of auto parts and service.

The most important thing for a person to remember about automotive credit cards is that person can not buy a car completely with reward points. The reward points are for a discount only. The discount usually ranges from $1000 to $3000. The vehicles a person can choose from vary as well. Each manufacturer chooses the particular models the rewards can be used towards purchasing. Used cars are usually not included as an eligible vehicle for the use of reward points and the cardholder is required to buy a vehicle that is new or leased.

When choosing an automotive credit card a person really needs to understand the rewards system and how it can be redeemed. They should also not forget this is a credit card and look at fees and interest rates, as well. Choosing a high interest rate card may actually end up costing the person more then they end up saving on their vehicle purchase. It is also important for a person not to get carried away and charge items they normally would not just to earn he points or, again, they could end up spending more than they save.

Automotive credit cards are great for someone who knows what vehicle they wish to purchase. They can then choose the card that suits this need. Automotive credit cards have a limit on how long points earned are good, so a person who does not use their credit card a lot may never see a good benefit. However, if a person is very careful and manages their automotive credit card they can end up saving a nice chunk of money off their next vehicle purchase.
