1. Remove assembly off vehicle.
2. Deliberately cut the ferrules or crimps, and remove the old ferrule and hose.
3. Install the replacement ferrule first that will hold the new hose in place.

How much does it cost to replace AC in car?

The Best in Auto Repair The average cost for air conditioning refrigerant line replacement is between $540 and $567. Labor costs are estimated between $105 and $132 while parts are priced at $435. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.

Is the high pressure line suction or discharge?

The high side, or discharge line, will be the line connected to the compressor from the bottom or lower position. It will not be wrapped in insulation and will be warm to the touch. This is where freon exits the compressor as a liquid.

Where is the liquid line on an air conditioner?

The liquid line comes out of the compressor and is liquid refrigerant on its way to the evaporator coil where it will pass through a valve which will allow it to expand and turn back into a gas. according to the laws of thermodynamics, this gas will become cold and supply the cooling effect for air conditioning.

Should my AC lines be hot?

A normal temperature would be around 90-to-100F. But if there was a problem (such as an overcharge, a defective outdoor blower, a very dirty outdoor coil, etc.), pressure inside the lines will be higher than normal, and as pressures get higher the temperature of the refrigerant inside gets higher as well.

Should both AC lines be cold?

When the system is operating, the large insulated suction line should be cold to the touch and sweating at any point where there is no insulation. The smaller uninsulated liquid line should be warm to the touch after the system has been operating for 10 or 15 minutes.

Why is my AC line not cold?

There are a couple of reasons for ice buildup in your AC — dirty coils or filters resulting in poor airflow, or a lack of refrigerant. If that doesn’t get the unit blowing cold air again, it could be refrigerant levels are low (see below).
