A refrigerant leak can cause a freezer to fail to get cold enough; however, leaks are very uncommon. Also, unlike some automobile air conditioners, it is never necessary to "top off" the refrigerant.

Refrigerant Leaks
If your air conditioner is low on refrigerant, either it was undercharged at installation, or it leaks. If it leaks, simply adding refrigerant is not a solution.
Refrigerant
A chemical that produces a refrigerating effect while expanding and vaporizing. Most residential air conditioning systems contain R-22 refrigerant.
Refrigerant- A substance that remains a gas at low temperatures and pressure and can be used to transfer heat. Freon is an example and is used in air conditioning systems.
Reglaze- To replace a broken window.
refrigerant gases (fluorocarbons) that can also be used as an air barrier, but not vapour barrier.
pony wall (mur bas, m.) A wall consisting of short sections of wood frame sitting on top of a conventional concrete foundation.
Refrigerant: Substance used in a refrigerator or air conditioner that absorbs and releases heat.
Refrigerant gas is compressed. Anything compressed will develop heat. A hot, high-pressure gas comes out of the compressor and into the outside coil.
Refrigerant
Substance used in refrigerating mechanism; it absorbs heat in evaporator by change of state from a liquid to a gas, and releases its heat in a condenser as the substance returns from gaseous state back to a liquid state.
Refrigerant in Group One (R-11.
chemical combination of carbon, chlorine and fluorine.
Carriage - The member which supports the steps or treads of a stair.
The refrigerant commonly used in today's residential air conditioners is R-22. Because of the suspicion that R-22 depletes the ozone layer, manufacturers will be prohibited from producing units with R-22 in 2010.
As the refrigerant passes into the condenser, a refrigerator condenser fan blows air onto the copper tubes. This cools the refrigerant inside, and the excess heat energy is exhausted into the room.
Handling the Refrigerant
The coolant used in most air conditioning systems is a refrigerant called Freon. If the system does not contain the proper amount of Freon, little or no cooling will take place.
FLUOROCARBON REFRIGERANTS
The fluids commonly used in refrigerating and air conditioning equipment to create the cooling effect. These fluids can damage the environment.

HOW IT WORKS
Refrigerant circulates in a closed loop between the evaporator and the condenser, capturing heat from the house and carrying it outside to a fan that blows it away.
He put some more refrigerant in the compressor and now it works fine without the air stoppage. Should I call the guy back to fix the coil or not? Any input would be greatly appreciated.
Check for proper refrigerant levels. Low levels indicate a leak that needs to be found and repaired immediately. Low refrigerant levels can burn out your compressor, resulting in the most costly repair when it comes to A/C, period.
Freon A trade name for a group of nontoxic, nonflammable refrigerants used in air-conditioning systems. Frieze A horizontal trim piece immediately below the cornice soffit.
Ammonia is a great refrigerant but it attacks copper. For this reason, the "coolworks" will use cast iron or steel pipes and fittings. The point? If everything you see is dirty but still painted, chances are that everything's okay.
Homeowners can take care of the basic maintenance of a central air conditioner system but you need a professional to service the compressor and to recharge the refrigerant.
As a result of the Montreal Protocol, a conference that grew out of international concern over the ozone-depleting qualities of CFC chemicals, the EPA is mandating the gradual phaseout of Freon, or R22 refrigerant.
The gas is burned to heat a chemical solution in which the refrigerant has been absorbed. Heating drives off the refrigerant, which is later condensed and evaporates by released pressure and, in turn, picks up heat.
In the heating mode, liquid refrigerant in the outside coils extracts heat from the air and evaporates into a gas. The indoor coils release heat from the refrigerant as it condenses back into a liquid.
Between the two units are two refrigerant gas filled pipes that take the cooled or heated gas to and from the exchanger. The gas inside the pipe is ether cooled or heated depending on the direction of the gas.
A motorized compressor forces refrigerant through two sets of metal coils. In one set, the refrigerant becomes a gas and absorbs heat. In the other set, the gas changes into a liquid and disperses that heat to the room air.
Simply put - a special fluid called a refrigerant circulates between an indoor coil and an outdoor condenser with a compressor. The refrigerant cools and dehumidifies the air, then the air is blown through ducts into the house.
Heat pumps extract heat from either the air or ground and transfer that heat by circulating a refrigerant through a cycle of alternating evaporation and condensation. The cycle can be reversed for cooling.
EVAPORATION COILS-The part of the air conditioning system where the refrigerant returns to gaseous form.
Frequently located in the furnace plenum.
FAILED-Something that no longer functions as designed or intended.
A/C Condenser: The outside fan unit of the Air Conditioning system. It removes the heat from the refrigerant gas and "turns" the gas back into a liquid and pumps the liquid back to the coil in the furnace.
Residential HVAC Term Freon is
a type of refrigerant used in air
conditioning systems.
The part of an air conditioning or heat pump unit that compresses the refrigerant gas so that it can absorb heat.

If your air conditioner runs all the time, but your house still doesn't get cool there may be a problem. The air conditioner isn't low on refrigerant, so it may be the size of your unit that is inadequate to cool your home. read more...
Make sure the door is removed so children cannot be trapped inside older models that have locking doors. Also, make sure that the refrigerant, such as chlorofluorocarbons or CFCs, is properly recycled.
CFC-a chemical compound that consists of chlorine, fluorine and carbon-was commonly used as a refrigerant in air conditioning systems, refrigerators and freezers. That is, until its harmful effects were realized.
The compressor which pumps the refrigerant makes a slight drone sound), you will have hot regions across the refrigerator. This will keep the compressor running always which requires professional attention. Do not attempt to open the inside.
