Does evacuating an AC system remove the oil?
To answer the question title, yes, you will have to add oil to the new refrigerant. Failure to do so will shorten the useful life of the A/C compressor's bearings through lack of lubrication. This will invariably lead to premature death of the compressor.
How do you tell if your AC needs recharged?
Signs your air conditioner needs freonAir conditioner is always running but it doesn't cool your home.Vents are blowing warm air.Electric bills are higher than before.There is a buildup of ice on refrigerant line.A hissing or bubbling sound from the refrigerant line.
How long does it take for home AC to get cold after recharge?
A properly functioning central A/C unit should be able to cool a moderate, four-bedroom home by 10 degrees Fahrenheit in three hours. Although the cooling power of your A/C also depends on the power, size, and age of your unit, your home should be noticeable cooler within a few hours.
Can I recharge my home AC myself?
Don't. The U.S. Environmental Protection Agency (EPA) recommends not replacing Freon or refrigerant by yourself for both health and environmental reasons. Only an EPA licensed technician is legally allowed to reclaim Freon.

How does refrigerant work in a gas system?
While in a gas state, the refrigerant passes through the evaporator, capturing heat. The refrigerant then moves through the A/C lines and into the condenser, where the refrigerant cools as heat is released outside of the passenger compartment, and the refrigerant returns to a liquid.
What is evacuation and recharge?
Evacuation and recharge service involves removing the MVAC refrigerant, cleaning it using recycling equipment (to remove impurities), recharging it into the system, and adding new refrigerant to replace the amounts that have leaked out. Evacuation and recharge service allows technicians to add the precise amount of refrigerant recommended by the MVAC manufacturer.
Why do shops charge for refrigerant recycling?
Shops might also charge a refrigerant recycling fee to offset the cost of purchasing or maintaining the specialized equipment that they are required to use to recover and recycle refrigerant. Other shops keep recovered refrigerants to make up for the cost of the recycling equipment.
What is MVAC retrofit?
Retrofitting an MVAC involves converting the system to use an alternative refrigerant. In most cases, chlorofluorocarbon chlorofluorocarbon A compound consisting of chlorine, fluorine, and carbon. CFCs are very stable in the troposphere. They move to the stratosphere and are broken down by strong ultraviolet (UV) light, where they release chlorine atoms that then deplete the ozone layer. CFCs are commonly used as refrigerants, solvents, and foam blowing agents. The most common CFCs are CFC-11, CFC-12, CFC-113, CFC-114, and CFC-115. The ozone depletion potential (ODP) for each CFC is, respectively, 1, 1, 0.8, 1, and 0.6. A table of all ozone-depleting substances (http://www.epa.gov/ozone/science/ods/index.html) shows their ODPs, global warming potentials (GWPs), and CAS numbers. CFCs are numbered according to a standard scheme (http://www.epa.gov/ozone/geninfo/numbers.html). (CFC)-12 MVACs are retrofitted to operate using hydrofluorocarbon hydrofluorocarbon A compound consisting of hydrogen, fluorine, and carbon. The HFCs are a class of replacements for CFCs. Because they do not contain chlorine or bromine, they do not deplete the ozone layer. All HFCs have an ozone depletion potential of 0. Some HFCs have high GWPs. HFCs are numbered according to a standard scheme (http://www.epa.gov/ozone/geninfo/numbers.html). (HFC)-134a. A technician might recommend that you retrofit your system because CFC-12 is an ozone-depleting substance and is being phased out of use. As supplies of CFC-12 diminish, the price of this refrigerant is increasing. It may be more cost-effective to have your system retrofitted rather than to recharge or repair it for continued operation with CFC-12. Learn more about the transition to new MVAC refrigerants.
What is top off on MVAC?
A top off involves adding refrigerant to your MVAC. There is no way for technicians to determine how much refrigerant is in your MVAC system when you arrive at the shop , so they must guess how much refrigerant to charge into the system. They may undercharge or overcharge the system—both of which impair system performance.
Why do motor vehicle air conditioners use refrigerants?
Motor vehicle air conditioners (MVACs) use refrigerants that can contribute to ozone layer depletion, climate change, or both. Stopping refrigerant leaks from MVACs helps protect the environment and improves your system’s cooling performance.
Can a technician detect a refrigerant leak?
Technicians can identify refrigerant leaks most of the time, especially if they are using an electronic leak detector certified under the Society of Automotive Engineers J1627 standard. However, technicians may have difficulty locating small leaks, even if using sophisticated leak detection equipment.
Is topping off more expensive than evacuation?
Topping off is less expensive than evacuation and recharge services. As an alternative to the flat fee, shops might charge separate fees for labor and for the amount of refrigerant charged into the system (e.g., based on recommendations from the MVAC manufacturer).
