A compressor is designed to increase pressure of a vapour (such as air) or a gas, or even a combination of vapours, in order for a machine to work efficiently. The idea is to increase the pressure by reducing the fluid specific volume through a passage of the fluid (or air) through a compressor. Compressors are usually defined as high-pressure and fans are defined as low pressure machines.

Air conditioning system contamination is a controversial subject, mainly when it comes to warranty issues. Warranties on components are declined when there are signs of contamination found in the failed components.
When replacing components on an air conditioning system, it is important to note why the previous system failed. Even though one uses the correct flushing solvent and uses the best equipment to clean a system of any contamination before fitting new components, it is still possible for some contamination to be stuck somewhere in the system. This is also the reason why it is recommended to replace all components when replacing failed components.

It is important to know how much oil one drains out of compressor and how much oil might be left inside it, so that one can determine how much oil to add to the system. Adding to much or too little oil can damage the air conditioning components and result in costly repairs.
A few things to note when draining oil from a compressor:
1) At what ambient was the comp drained at? Hot = more drained oil, Cold = slow/ less oil.

Why should to clean your Car A/C System ?
1.The compressor is wedged by something. There are some bits of aluminum and
dirt in the air condenser or system. The tube of system is narrowed,A/C efficiency can't be working smoothly and  not cold enough.The voice of compressor is getting loud and maybe caused it to waste more oil due to the overload Car A/C Cycle System Model:

Summary: Practical troubleshooting tips for diagnosing and repairing problems with car air conditioning systems. Questions about fixing car A/C’s, answered by me, Dennis, an ASE master auto technician. When I first starting to work on car air conditioning  it was the 1980′s. R12 was the only refrigerant that was used. Most cars took much more refrigerant during that time. Although vehicle’s systems took more refrigerant (Freon) because the capacities

A common question has been; What year did the car manufacturers start using 134A? The answer is 1995. While there are new refrigerants on the horizon for automotive use, the overwhelming majority of car AC systems today use 134A refrigerant. R12 refrigerant was used in cars built in 1994 or prior. Although in the mid nineties the production of R12 was halted, many repair shops recycled R12 for several years.  R12

We'll discuss the refrigeration cycle using this cycle diagram.

Component #1 is the compressor.

It takes refrigerant vapor in from the low pressure side of the circuit, and discharges it at a much higher pressure into the high pressure side of the circuit.

Why customer choose us?

Because we fix it right, the first time.  Oftentimes a simple refrigerant recharge is all it takes to get your system blowing cold air again.  Over-the-counter options are now available for those that prefer to ‘do-it-yourself’.  These alternatives are cheaper than a professional service but do have certain drawbacks.


While most people think of air conditioning as a way to add cool air to the inside of your car, would you be surprised to know that in actuality air conditioning systems actually remove heat from the passenger compartment and the cool air you feel blowing at you is a bi-product of the heat transfer happening inside the air-box behind your dashboard?
