Car AC Lower Pressure Hose Replacement

What is the AC Low-Pressure Hose all about?

The AC system has many components: compressor, condenser, receiver dryer, evaporator, and hoses. For an AC system to work, it needs a gas or liquid substance, a refrigerant, (R-12 in older cars, R-134a in 1995 and newer cars). Hoses carry the refrigerant throughout the AC system. A car usually has four or more hoses. The AC system hoses are connected to the evaporator, condenser, dryer, and compressor.

Keep in mind:

Due to normal wear and tear, the hoses can crack and leak refrigerants. Because the cracks cannot be sealed, you will need new hoses.

How it’s done:

  • Use the manifold gauge set to measure the pressures.
  • Inspect the AC system for leaks.
  • Remove refrigerant from the system.
  • If an AC hose is leaking, remove and replace the hose(s).
  • Evacuate and recharge the AC system.
  • Check the car for system leaks.
  • Check for proper operation of the AC system.

Our recommendation:

The AC system is a sealed unit. It is not something you will inspect or service unless you notice a change. If you notice a change in the temperature of the air through the AC vents (not as cold as it should be), schedule an inspection.

What common symptoms indicate you may need to replace the AC Low-Pressure Hose?

  • Air conditioning is not as cold as it should be.
  • Air conditioning does not work at all.

How important is this service?

In addition to your comfort, air conditioning systems add value to your vehicle. It would be best if you kept your AC fully operational. In some systems, the hot and cold air are blended to achieve the desired temperature setting. In these cases, when the AC system fails, you will not only NOT get any cold air, but the entire temperature regulation is thrown off.

Mr. Tony provided outstanding service. He communicated clearly from the start, letting me know exactly when he would arrive.

Excellent Service by Tony Da Silva

Tony was assigned to my rescue when my vehicle was not starting in the morning. Initially our appointment was scheduled at 16:30 through our communication during the day we both agreed that he can come at anytime once he has done with his other duties. He arrived an hour early at 15:30. As pro he immediately diagnosed the problem of my vehicle. The problem has been sorted now and the car is able to start smoothly. His level of professionalism and customer oriented is out of this world. Keep up with the good work Tony and Thank you.
