What is an AC high-pressure hose replacement?
Your car’s air conditioning system has a low-pressure side and a high-pressure side. On the low-pressure side, your car’s coolant is a gas, and on the high-pressure side, it’s a liquid. The low and high-pressure hoses are noticeably different in size, with the high-pressure hose being narrower.
An AC high-pressure hose replacement involves removing the line on the high-pressure side and installing a new one. If you think your AC high-pressure hose may have a crack, leak, or clog, a mechanic can take a look at your air conditioning system and replace it if necessary.
How do I know if my car's AC hose is bad?
The air conditioning unit in a car is a sealed system, and most experts will tell you it doesn't need to be serviced or inspected until it stops working properly. To determine whether the hoses are causing the problem, the mechanic will open the system to inspect it.
If your AC is blowing cool but not cold air, or if your AC system fails to lower the thermostat at all, you might have an issue with your high-pressure hose. Refrigerant leaks are accompanied by a slightly sweet chemical smell. Seek medical attention as soon as possible if you feel dizzy, short of breath, nausea, or experience difficulty breathing.
How long do car AC hoses last?
A high-pressure AC hose can last for eight to ten years. Regular maintenance and checks of your AC system can help extend its lifespan. On the other hand, if you neglect to flush the system, or you live in an extremely hot climate, you might need a replacement sooner.
Can I fix an AC leak myself?
A high-pressure AC hose replacement isn’t a good DIY project. It requires specialist equipment to suck the refrigerant from the AC lines and then return it. In addition, refrigerant is flammable, toxic, and corrosive—definitely not something you want to spill on your skin or clothes!
