How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my AC low-pressure hose replacement?

Check your owner’s manual to find the replacement hose part number, or ask your mechanic to find the part. To do 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 cost between $150 and $200. 
You’ll also need refrigerant, but the EPA limits its sale to certified technicians. Most auto shops or dealership service centers include refrigerant in your repair bill.
In addition to the new hose and refrigerant, a mechanic uses specialized tools like end wrenches, socket and ratchet sets, vacuum pump, and attachments for AC lines.
Top brands for low-pressure hoses include Four Seasons, UAC, and ACDelco. You can purchase all these parts for your car from retailers such as AutoZone, Amazon, and Advance Auto Parts.
If you’re on a tight budget, an aftermarket part might be the way to go. It’s also a good option if you can’t easily get an OEM part. However, if you install an aftermarket part, you could risk voiding the warranty.
Head to an auto body shop or auto part store like AutoZone or Advance Auto Parts. If your local shop doesn’t have the part in stock, they can order it for you, or you can find it on Amazon. Remember to check your owner’s manual for the replacement part that 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:
  1. Evacuate refrigerant from the AC system
  2. Remove the AC low-pressure hose
  3. Check that the new low-pressure hose matches the old hose
  4. Install the new AC low-pressure hose
  5. Recharge the AC system
  6. Check the vehicle for system leaks
  7. Test the AC system
Good to know: To make their diagnosis, a mechanic uses a manifold gauge to measure the pressure in the low-pressure and high-pressure hoses. Then, they’ll visually examine the entire AC system for refrigerant leaks.

What happens if I don’t replace my AC low-pressure hose?

If you continue to try to use the AC system with a leaking hose, it will keep leaking refrigerant and could damage other AC components. More damage to the system means higher repair bills, so don’t wait to fix the AC low-pressure hose!
In some vehicles, the system blends hot and cold air for custom climate control. If the AC fails in one of these systems, it disrupts the whole temperature system.

What is an AC low-pressure hose?

Your car’s AC works using a system of high- and low-pressure hoses that are connected to the evaporator, AC condenser, dryer, and AC compressor. The low-pressure hose is one of the vital hoses that carries refrigerant throughout the system. It’s also called a suction side hose.
Here’s how refrigerant moves through the AC system (starting in no particular order). The system draws in hot air, and the evaporator coil absorbs the heat. The liquid refrigerant in the coil turns into a gas and heads to the compressor. To get there, it travels through the low pressure hose.
The compressor squeezes the refrigerant gas to raise the refrigerant’s pressure. Then, it moves to the condenser, where it comes into contact with outside air. The outside air absorbs the heat, which lowers the refrigerant temperature and makes it shift back into a liquid. 
The cold refrigerant liquid travels back through the expansion valve and into the evaporator, where the cycle begins again.
If the AC low-pressure hose begins to malfunction, your entire AC system may be in trouble. If left untreated, your air conditioning system could suffer substantial damages.

How do I know if my AC low-pressure hose is bad?

You’ll probably realize pretty quickly that something is wrong with your car’s air conditioning. Here are signs that the AC low-pressure hose is causing the problems:
  • The air conditioning isn’t as cold as it should be: If you’re still getting some cool air, just not as much as you’d like, the low-pressure hose might be leaking.
  • There are crimps or kinks in the hose: Inspect the low-pressure hose for signs of damage. Bends in the hose prevent refrigerant from flowing into the compressor. 
  • The AC doesn’t work at all: The low side moves refrigerant to the compressor, so if the low-pressure hose is bad, the system can’t make cold air.
  • Refrigerant leaks on the hose: While it’s easier to spot leaks from the high-pressure hose, low-pressure hose leaks appear as a greasy film. Look near the fittings to identify a leaking low-pressure hose. 

How often should an AC low-pressure hose be replaced?

AC low-pressure hoses typically last eight to ten years before they need to be replaced. The older the hose is, the more likely it is to leak.
Keep in mind: AC pressure hoses aren’t inspected as part of regular maintenance. If you suspect a problem with your air conditioning system, get the hoses inspected.

Can I replace the AC low-pressure hose myself?

Replacang the hose is a bit more complex than just swapping out parts. Doing the work requires releasing the refrigerant from your car’s AC, and there are EPA regulations about how to do this safely, so it’s not a good DIY project. It’s best to leave the hose replacement to a mechanic who specializes in AC repair.

FAQs

Over time, standard wear and tear can cause a low pressure hose to crack. The refrigerant that passes through the hose is corrosive so it will wear out the inside of the hose.
No, the low-pressure hoses are bigger in diameter, while the high-pressure hoses are smaller.
Most hose manufacturers make the lo- pressure hoses blue and the high-pressure hoses red.
