Car Air Conditioner -How solve Problems of Your Car AC

Car Air Conditioner

These hot days are now ideally suited for car air conditioner.This is the best time to prove the efficiency of Air Conditioner. In extreme heat, when we start the Air Conditioner in a hot car, we feel something happens only after a few minutes. Before starting the Air Conditioner in a very hot car , it is good to open the windows and keep for sometime. Even after switching on the Air Conditioner if we keep the windows open it will help the hot air to move out of the vehicle. In the beginning put the blower in high position ,and as it gets cold we can move the blower to a lower position.

A good working Air Conditioner’s efficiency reduces in extreme heat, so what about a fault Air Conditioner? Will be very difficult. But if we are careful we can avoid all these problems.

The Commonly Occurred Problems of AC

One:- The main problem with air conditioner is the less amount of refrigerant. The smooth working of an air-conditioned is made possible through the refrigerant. In modern cars, Freon free refrigerants like R-134A is being used. If the refrigerant’s pressure reduces, then also the cooling capacity reduces. We can only check whether it is time to top up. Look through the top glass of the receiver dryer bottle which is fitted with engine bail. If we see bubbles then it means it’s time to fill the refrigerant.

Blockage: A/C system involves a lot of tubes. If there is a block in any one of these, then the cooling capacity reduces. If some small particles of old tubes falls inside or if rust is formed on the tubes, then also cooling reduces. If there is a hindrance in the smooth flow of the refrigerant besides reduction in cooling ,the compressor which is an important part of the A/C system will get spoilt.

Condenser problems: It is common for dust particles to enter into the condenser which is usually kept in front of the radiator. It is better to sometimes clean the condenser with strong air blow or with water.Those condensers which are not cleaned for years can have problems.

 If the fans used for cooling the condensers have problems ,then also there is an issue. If there is a problem with the fan motor , relay or other electrical circuit then also the performance degrades. Some cars have a common fan for both the radiator & condenser. Moisture: If moisture enters the refrigerant, then problems can occur. Moisture will soon become ice and cause blockage in the tubes. If more air also happens to enter, that will also adversely affect the cooling capacity.

My A/C only works for about two months after it gets a freon charge. I would replace the problem part for the hundreds of dollars they want to fix it, but the vehicle has almost 311k...I am afraid to sink too much into it!

Nice tips. I guess that gas problem, leekage or quality of the gas used itself play a major role in addition to what you mentioned. Thanks.

thanks for sharing tips , Quality and Quantity of materials or parts used is main reason for many of the problems mentioned above

I agree with Kevin. The quality of the parts being used seems to be the reason for some of my issues in the past.

That's right, gas problem, leekage or quality of the gas used itself play a major role in addition to what you mentioned. ... Thanks for simply tips but so useful.
