Why is My Car AC Running But Not Cooling My Car?

The air conditioning in your vehicle seemed to work fine last year. Now that it’s getting warm on the road during summer, it’s time to run the auto air conditioning. But it won’t get cold in the car. 

You could have several problems. There’s no way to tell without an experienced car AC repair technician to diagnose the issue. Mast Service Center Inc. in Etna Green, IN can check the level of the refrigerant, the compressor and other components, and leaks.

Air Conditioning Refrigerant Leaks

The refrigerant in the vehicle is invisible, so you can’t see if it’s leaking. The only way to tell is to check the system with air conditioning gauges to determine if a portion of the refrigerant leaked out. If so, our AC repair techs in Etna Green, IN will add refrigerant mixed with dye to locate leaks.

The aircon could leak in many places, like hoses, dryer or accumulator, expansion. The air conditioning could leak in many places, like hoses, dryer or accumulator, expansion block or orifice tube, evaporator, condenser, or compressor. The dye in the system will leak out in the problem area and leave a green stain on the hose or component.

Malfunctioning AC Components

Just one malfunctioning component in the auto air conditioning is enough to make the system not work. The most common malfunctioning components are the compressor and the orifice tube or expansion block. 

Other components include:

  • High and low-pressure hoses
  • Condenser
  • Compressor
  • Accumulator or dryer
  • Orifice tube or expansion block
  • Evaporator


Whenever AC technicians in Etna Green, IN have to open the system to replace a component, they must also replace the dryer or accumulator as it could become contaminated.

Clogged Air Conditioning Systems

Air conditioning systems can become clogged with old oil, moisture, and debris. The system compresses a liquid refrigerant into a gas, then goes through the system and absorbs the hot air. The dryer or accumulator pulls any moisture out of the refrigerant as it goes through the system.

Debris can get into the system every time someone opens the system. When the compressor malfunctions, it also sends debris through the system, which could cause a clogged system.
