Mr. Freeze - The Auto Air Conditioning Good Guy!

He may have been hellbent on destroying that pesky Batman … but when it gets to summer in the South, especially if you have to commute work and try to arrive looking fresh, you'd be glad to have him in your life! Mr. Freeze would have been infused with some sort of refrigerant -- just like your automotive air conditioning system is. However, your car was most likely not involved in a cryogenics acicident while trying to treat its sick wife! So what is the science of Mr Freeze -- how do refrigerants actually work in your AC system to cool you down?

A refrigerant gas is placed in a sealed system of pipes or tubes, and pressurized with a compressor. The compressor is one of the most common failure points of your AC parts system. The compressor needs to be able to create enough pressure to turn the refrigerant gas into a liquid.

The refrigerant is almost always mixed with a small amount of oil, which helps lubricate the system. There are very specialized oils used in auto air conditioning systems. As the refrigerant is pressurized, it becomes very hot, just as a bike tire does when you pump it up (increasing its pressure). The liquid passes through an expansion valve into a chamber where the pressure is much lower, allowing it to return to a gaseous state.

In returning to a gas, the refrigerant absorbs heat from the air around it. A fan then blows the cooled air into the car, and another fan generally blows air from the hot part of the pipes away from both the car interior and the engine (ideally).

There are quite a few possible failure points in this system. If the compressor doesn't work hard enough to completely condense the refrigerant into a liquid, the air won’t be as cold as it could be. If the expansion valve is leaky, you may get cold air further back in the system. Many auto air conditioning systems also incorporate elements like accumulators, driers, evaporators and condensers, which all have the potential to leave you sweaty and dizzy after the commute to work, if they aren't operating properly.

There is a long list of refrigerant substances used by DuPont, which assigns an R-number to each chemical. The list runs from R10 up to R1250 (with quite a few gaps), and also includes letter designations after some of the names. is currently the most commonly used chemical in automotive air conditioning systems.

Recharging Your Auto Air Conditioning

It's one of those things that an alert handyman can usually save bit of dough on -- recharging the car's automotive air conditioning unit. It isn't as complicated as repairing the compressor, replacing an expansion valve or a condenser -- but if you have just done any of these tasks you'll need to recharge the system. If this is the first time you'll be doing the task, we have some tips and tricks to make it easier for you at DiscountAutoAC-CompressorParts.com.

Do you really need to?

The first thing you need to do is be sure that your system needs recharging. The gas in your auto AC doesn't just run out of oomph. It either leaks out through a compromised part of the system, or has to be purged when a part is repaired or replaced. If you are sure that your refrigerant is the reason your auto air conditioner isn’t blowing cold any more, then fix any leaks before you recharge! Otherwise you'll be doing it all again before you know it.

Check for leaks

Use a manifold gauge set to check for leaks before you begin recharging.

Do you have the right refrigerant?

Do it all properly -- it can be temping to try the canister of R12 left over from your old Mercedes on your wife's little Toyota, but if the Toyota uses R134A refrigerant, the tips won’t fit, and the oil won’t be suitable. Don’t mix refrigerant, and don't use the wrong refrigerant. Guessing which is supposed to be in the auto AC could give you some nasty cold burns, too -- so take it to a mechanic and save yourself the medical bills!

Replacements for R12

The most important thing that you should know, though, is that it is illegal to recharge your own auto AC with R12. The gas is harmful to the ozone layer and has to be dealt with by a licensed professional. However, you can use products like Freeze 12, which are equivalent to R12 in their use of oil, but are not ozone depleting.

Keep checking pressure

Once the lowside pressure is at around 30 psi, the high side pressure can continue to increase to dangerous levels. Keep watching it to avoid damaging your auto compressor or other AC parts.

Get the entire kit with pressure gauge

Don’t just buy a refill canister -- it makes sense to buy the whole kit, rather than trying to piece the other parts together. You probably won’t have the right size tips floating about, and having a kit with a pressure gauge included is very handy for recharging your auto air conditioning.

The heat is on

The Heat is on

Summer is definitely here and so are the high temperatures. How hot is it? Well, you could be in rush hour traffic and temps can exceed 125 degrees outside the car. That is of course before the 100 percent humidity. How can you beat the heat? What are your only resources if you air conditioner in your car goes out? Well, the dealerships are way overpriced; I guess they think the general population can bring them out of debt. How much can you afford to spend in this horrible economy that we live in now? Is the option of a new car not even a choice right now? Well, guess what: you are in the same boat as the rest of us.

The auto air conditioning that the manufacturer installs in our automobiles is very efficient and a blessing everyday we step into that nice 60-degree car after being outside.The only issue is that like our home the air conditioning in the cars are not going to work forever. So if you are like me, then you will understand that as soon as you do not need the air conditioner to go out, it will. Here is the worst part: some cars today that run on 1 belt for everything are dead without the air conditioner spinning.
