What parts do I need for my AC low-pressure hose replacement?
Refer to your owner's manual to locate the replacement hose part number, or consult your mechanic for assistance in finding the part. To proceed with a hose replacement, here's what you'll need:
- New AC low-pressure hose: This blue AC hose is larger than its red, high-pressure counterpart. Replacement hoses typically vary in price.
You'll also require refrigerant, but its sale is restricted by the EPA to certified technicians. However, most auto shops or dealership service centers typically include refrigerant in your repair bill.
Besides the new hose and refrigerant, mechanics require specialized tools like end wrenches, socket and ratchet sets, vacuum pumps, and attachments for AC lines.
Top options for low-pressure hoses include various manufacturers. You can find these parts for your car from various retailers.
If you're on a tight budget, opting for an aftermarket part might be suitable. It's also a good choice if acquiring an OEM part isn't convenient. However, installing an aftermarket part could potentially void the warranty.
Visit an auto body shop or auto part store to find the necessary replacement part. If the part isn't available at your local shop, they can order it for you, or you can search for it online. Remember to consult your owner's manual to ensure the replacement part matches your vehicle.

How do you replace a low-pressure hose on an air conditioner?
Once the mechanic has diagnosed the problem with your AC system and identified the faulty low-pressure hose, here’s how they’ll replace it with MyMechanic in Malaysia:
- Remove refrigerant from the AC system.
- Remove the AC low-pressure hose
- Verify that the new low-pressure hose matches the old hose.
- Fit the new AC low-pressure hose.
- Recharge the AC system
- Check the vehicle for system leaks
- Test the AC system
What happens if I don’t replace my AC low-pressure hose?
If you persist in attempting to use the AC system with a leaking hose, it will continue to leak refrigerant and may harm other AC components. Additional damage to the system results in increased repair costs, so don’t delay in repairing the AC low-pressure hose!
In certain vehicles, the system combines hot and cold air to offer customized climate control. If the AC malfunctions within these systems, it disrupts the entire temperature regulation.
What is an AC low-pressure hose?
Your car's AC operates through a system of high- and low-pressure hoses connected to the evaporator, AC condenser, dryer, and AC compressor. The low-pressure hose is crucial as it carries refrigerant throughout the system. It's also referred to as a suction side hose.
Here's how refrigerant circulates through the AC system (starting in no particular order): The system pulls in hot air, and the evaporator coil absorbs the heat. The liquid refrigerant in the coil transforms into a gas and moves toward the compressor. It reaches the compressor by traveling through the low-pressure hose.
The compressor compresses the refrigerant gas to increase its pressure. Then, it proceeds to the condenser, where it encounters outside air. The outside air absorbs the heat, reducing the refrigerant's temperature and causing it to revert to a liquid state.
The cold refrigerant liquid returns through the expansion valve and enters the evaporator, initiating the cycle anew.
If the AC low-pressure hose starts to malfunction, your entire AC system could be at risk. Failure to address this issue promptly could lead to significant damage to your air conditioning system.
How do I know if my AC low-pressure hose is bad?
You'll likely notice fairly soon if something is amiss with your car's air conditioning. Here are indications that the AC low-pressure hose may be the culprit:
- The air conditioning isn’t as cold as it should be:If you're still receiving some cool air, albeit not as much as desired, there could be a leak in the low-pressure hose.
- There are crimps or kinks in the hose:Examine the low-pressure hose for any indications of damage. Bends in the hose can obstruct the flow of refrigerant into the compressor.
- The AC doesn’t work at all:The low side transfers refrigerant to the compressor, meaning that if the low-pressure hose is faulty, the system cannot produce cold air.
- Refrigerant leaks on the hose:While leaks from the high-pressure hose are easier to detect, low-pressure hose leaks manifest as a greasy film. Examine the area near the fittings to identify a leaking low-pressure hose.
How often should an AC low-pressure hose be replaced?
AC low-pressure hoses generally have a lifespan of eight to ten years before requiring replacement. As the hose ages, the likelihood of leakage increases.
Can I replace the AC low-pressure hose myself?
Replacing the hose involves more than just swapping out parts. It requires releasing the refrigerant from your car's AC system, and there are EPA regulations to follow for safety. Thus, it's not recommended as a DIY project. It's best to have a mechanic who specializes in AC repair handle the hose replacement.
FAQs
Over time, regular wear and tear can lead to cracking in a low-pressure hose. The refrigerant passing through the hose is corrosive, causing wear to the interior of the hose.
Correct, the low-pressure hoses have a larger diameter, whereas the high-pressure hoses are smaller.
Similarly, for those sensitive to odors or certain chemicals, investing in a charcoal air filter could be beneficial. Charcoal filters excel at absorbing unpleasant odors and gases like sulfur dioxide, contributing to a more comfortable breathing experience for drivers.
Most hose manufacturers typically color-code the low-pressure hoses blue and the high-pressure hoses red.
