Can You Do An Ac Recharge Yourself
Do you consider yourself to be pretty handy as far as working on cars is concerned? If you do, then you might want totackle an AC recharge on your own. You can pick up a bottle of refrigerant and a recharge kit at most auto part stores and do it yourself if youre so inclined.
To do it, youll want to begin by turning your car on and firing up your AC system to see whether or not your AC compressor engages. As long as it does, that likely means thatyour compressor is working fine and that you just need to add some refrigerant to your car to get the AC system working again. Doing that is often as easy as attaching the recharge hose from your kit and using it to add more refrigerant to your AC system until there is enough of it working its way through the system.
You can have the AC system in your car blowing ice-cold air again in no time by taking these steps. But you should avoid trying to take on an AC recharge if you dont know exactly what youre doing. The last thing you want to do is attempt to save a few bucks on the AC recharge cost and end up doing damage to your AC system or to your car as a whole. Its better to rely on the professionals for help if you need it.
You Might Need An Ac Recharge If:
- You notice the air blowing is not cold or not as cold as it used to be.
- AC Clutch fails to engage. The clutch is controlled by the AC pressure switch, which determines the level of pressure within the system. When the level drops down below a certain level, it fails to engage, making it unable to circulate even the tiniest amount of refrigerant. Refrigerant is essential in the operation of your air conditioner. Refrigerant creates the proper pressures and carries oils that are used to lubricate internal components of the system, protecting elements and preventing overheating
- You spot greasy residue from air conditioning connections or mechanisms and noticeable fluids on the ground. The fluid will continue to leak out until the system is no longer able to function properly.
Since air conditioning systems can develop leaks at any time, theres no specific time or mileage for an evacuation and recharge to be performed on your system. However, you shouldnt wait until your vehicle begins showing signs of AC troubles. Have your vehicles air conditioning system inspected every Spring to ensure everything is functioning well before the heatwave rolls in.
How Do You Know When Your Air
The first sign that your air-con needs regassing is that the air being blown from the vents is not as cool as it used to be, or it doesnt feel any different when the AC is switched off.
If you cant remember the last time the system was regassed, its probably worth doing. Alternatively, many specialists are happy to perform a free check.

Air con will certainly provide the most comfort on a hotday and the driver has the option to control the temperature and the blowers.Having the window down provides just one uncontrollable setting and it can getquite loud and blustery in the cabin the faster you go, the worse it gets.Also, when travelling at speed, the vehicle becomes less aerodynamic andexperiences drag so youll be using more fuel to get to your destination.That said, using the air con comes at a price too. The compressor at the heartof your air conditioning system requires energy in order to circulate cold airaround the vehicle. It gets the energy from the engine so when the airconditioning system is turned on you will also be using more fuel. So foroptimum fuel efficiency, its windows down at low speeds, air con on at highspeeds.

Heres How The Ac System Of A Car Works In Better Detail:
The system uses a special refrigerant gas R134a and is divided into the high-pressure side and the low-pressure side.
Low-pressure R134a refrigerant vapor enters the compressor and gets compressed into high pressure and high-temperature R134a vapor. The vapor that also contains special lubricant oil is circulated into the condenser . As the high temperature and high-pressure vapor travels through the condenser, the heat is released into the much cooler ambient air. While the vapor is cooling down and passing through the condenser tubes, it condenses into a liquid . This high temperature and high-pressure liquid travels through the filter drier and onto the small orifice of the expansion valve. This valve provides a restriction against which the compressor pushes.
When the liquid refrigerant passes through the expansion valve, its pressure lowers and so does its temperature. Now its a low pressure and low-temperature vapor. Next, the refrigerant passes through the evaporator. The hot air of the cabin is being blown through the evaporator, thus cooling the air of the cabin down. Then, the R134a refrigerant is pulled back into the compressor and the cycle begins again.

- Run the system at least once a week. During the winter months, you might not think to run the system, but you want to continue circulating the Freon. Thankfully, the defrost system runs through the air conditioning, so you can turn that on for a few minutes. This simple step can ensure the system is running when the weather turns warm again.
- When you have the air conditioning on, make sure your windows are closed. Having the windows open means that you are pumping air outside. You are also using more fuel to push out the air that isnt being used.
- Have a technician service the system at least once every two years. If you can do it yourself, that works. A little bit of maintenance can help prevent larger problems down the road.

How Long Does Car A/c Gas Last
Air Conditioners outside of the automotive industry can last indefinitely as long as you dont create a leak. The compressor and associated coils are hermetically sealed. The compressor operates inside this sealed system. So if nobody damages it somewhere it wont leak, but when it comes to vehicles its a different story.
Automotive air conditioning overtime will run into problems. The compressor isnt hermetically sealed. So the clutch seals can dry out especially if it hasnt been operated for some time and will leak as a result. Your car air conditioning system is made up of several components such as the compressor, the condenser, the evaporator as wells other intricate parts such as hoses, valves, seals etc all of which lay under your vehicle bonnet and is susceptible to damage.
