Two hoses could be faulty or damaged. First, there is a low-pressure side where the refrigerant starts out as a gas and cycles between the compressor and expansion valve. There is also a high-pressure side that converts refrigerant into liquid and carries it from the compressor to the receiver or dryer where it turns into cold cabin air. Each one has different symptoms if it is going bad.

What happens when the high-pressure hose goes bad?

The symptoms of a failing or defective high-pressure air conditioner components include:

  • Your cars air conditioner will not produce cool air. Since the high-pressure side delivers the refrigerant that makes the cool air, this signals that there is a problem.
  • Refrigerant is leaking. If you notice liquid around the clamps and fittings or see evidence of it dripping, you will need to check your high-pressure side.
  • The high-pressure side has physical damage. Since its location is in the engine bay, it can become damaged by heat and friction. If you see loose threading, cracks, or tears, it is time to replace it.
What happens when the low-pressure hose goes bad?

Since the low-pressure side carries gas instead of liquid, diagnosing problems with it requires some additional steps. As with the high-pressure side, a lack of cool air is a symptom of air conditioning problems. But with the low-pressure side, you need to look for these additional signs.

  • First, look for condensation on the low-pressure components. You will not see liquid dripping on the low-pressure side, so finding small cracks and tears may be more difficult. But if you see a greasy or oily residue on the fittings, there is a leak.
  • Second, look for bends, crimps, or kinks in the hose. These imperfections will obstruct the air flow and prevent the gas from the refrigerant from reaching the compressor and the high-pressure side of your air conditioner.
Where are the hoses in the Hyundai Elantra air conditioner located?

Make sure that you are familiar with the components of your cars air conditioning system, including the compressor in the front of the engine, the condenser in front of the radiator, and the evaporator inside of the dash.

  • First, locate the compressor. Under the hood of your car, look for the fan belt that drives the AC compressor. You should see two hard rubber lines attached to the compressor.
  • Next, locate the high-pressure end. This end is the smaller one that leads from the compressor to the condenser in front of your radiator.
  • Finally, locate the low-pressure end. It is the larger one that leads from the inside of the cabin and goes into the compressor.
