Is there anything worse than your car's air conditioner failing during the hot summer months? While you don't need A/C charging and refrigerant to drive your car, you do need it to have a comfortable ride. Knowing more about A/C hoses will ensure that you make the right choice for your car. You'll also learn what to look for when checking the hose. After all, they don't last forever, and the damage is often felt as weaker air.

What is an A/C Refrigerant Hose?
An A/C refrigerant hose, better known as just an A/C hose, is a rubber hose fitted with aluminum attachments at the ends. The rubber is specially designed to withstand high-pressure refrigerant as it flows through and provides you with cool air. The hose serves an essential function. It ensures the refrigerant can properly run through your A/C system to make the ride more comfortable. Any damage, from small tears to full rips, can have major impacts on air quality. Issues often lead to the A/C feeling weaker or warmer than it should.

What is an A/C Recharge Hose?
There are also A/C recharge hoses, which are similar in design and function. The major difference is that recharge hoses are used for recharging the refrigerant when you're running low. Many times, it's not a hose issue that's causing the air to feel warm. It could just be low refrigerant. These hoses are also made from rubber, and they carry the refrigerant from the canister to your car, which gives you the cool air that you need. Most professionals use specialized tools and gauges to ensure the A/C is being recharged to its proper level.

How Does an A/C Refrigerant Hose Work?
The hose is a simple part of the whole A/C system. It carries refrigerant, such as R-134a, between the major points of the A/C system. It's like a vein carrying blood to the heart or brain. Most people want to know about the major components, which would be the compressor, condenser and evaporator. These three work in conjunction to provide you with cool air, and the hose serves as the major highway between them for the refrigerant.

The compressor turns the refrigerant into a high-pressure liquid, which is then passed over to the condenser. It's cooled down here and then passed over to the evaporator, which then sends the air your way to keep you comfortable. All three parts work in perfect harmony to make the air hospitable.



Signs of a Faulty A/C Refrigerant Hose
Hose damage will prevent the A/C from working properly. These are some signs to consider or look for when checking the hose.

If the hose is bent or pinched, then you may simply need to return it to its original position for better performance.

Another one of the signs of a faulty A/C refrigerant hose is that the air doesn't feel as cool as it should. This could also be from low refrigerant.

The most obvious sign would be physical damage to the hose, such as cracks or breaks. A broken hose should be replaced so that it can properly carry refrigerant again.

Leaking is a major sign to watch for. Noticing any leaking refrigerant on the hose means it must be replaced immediately. This can quickly deplete your refrigerant, and it can lead to major issues with the A/C system in general.

If anything feels off with the air, then check the hose first. Not only is this the most common culprit, but it's also the easiest to repair.

What to Do if A/C Stops Working?
Automotive AC systems are closed systems that are subject to harsh weather and damaging road conditions. Your AC has plenty of spots for refrigerant leaks to occur in metal components like the condenser, evaporator, accumulator or drier, as well as in the rubber components; hoses, O-rings, gaskets. An AC leak will lead to warmer air from your vents over time. In most cases this can be fixed with a proven stop leak additive to seal up any leaks.
