One question that many people ask when buying Carrollton Texas Craigslist cars is whether or not the air conditioning system is functioning. Living in Texas, it is absolutely mandatory to own a car that has a functioning air-conditioning system. With the summer temperature highs extending well above the 100s, driving around in a vehicle that does not a working air conditioning system can be hazardous to your health. Each summer, thousands of Texans suffer from heat stroke from prolonged exposure to the hot weather. When buying a used car, having a working air conditioning system is just as important as the engine and transmission. Anyone who has ever had air-conditioning work performed can vouch that it can be quite costly. A new compressor alone will set you back $500 or more. Before purchasing a used car, be sure to thoroughly inspect the air-conditioning system to ensure that it is in fact functioning properly. You do not necessarily have to be an air-conditioning specialist to perform a few basic diagnostics on an air-conditioning system. On almost every vehicle, the entire system consists of a compressor, condenser, evaporator, and a dryer receiver. Refrigerant is circulated through the system by the compressor. The gas then expands and contracts as it circulates through a continuous loop. Often times, leaks develop and system components malfunction. When it comes to purchasing a used car, it is up to you to determine whether or not the vehicle you are about to purchase has a properly functioning air-conditioning system. Don’t make a several hundred dollar mistake. Be sure to thoroughly inspect the air-conditioning system and all of its components before making a purchase.
Inspecting an air-conditioning system is rather simple. From Craigslist cars Columbus South Carolina to cars in Carrollton, the procedure for inspecting the air-conditioning system begins by starting the vehicle and selecting turning on the AC to “max cool”. Observe the temperature that is exiting through the vehicles vents. A great tool to own is a thermometer which can be purchased at your local auto parts store such as Auto Zone. The next thing to do is to look under the vehicles hood at the compressor. If hot air is coming out of the vents and the compressor is not turning than you should install a pressure gauge on the low pressure side. Compare the pressure reading to the manufacturer specifications. If the pressure is within specifications then tried to bypass the low pressure switch to see if the compressor engages. If it does in fact engage, the culprit is likely a low pressure switch. If the system is low on refrigerant, add the necessary refrigerant to the low pressure side. In today’s modern vehicles, most systems take 134a refrigerant. If the vehicle is older and has not been retrofitted, it may require R-12 refrigerant which is quite costly and requires a license to purchase.
When buying a used car in Texas, the last thing you want is a vehicle that does not have air-conditioning. Summer days can be brutal and AC repairs can be very costly. When searching Craigslist cars Carrollton TX, be sure that the vehicle you are about to purchase has a functioning system.
