Refrigerant is a working chemical that runs through your car's A/C system in either a gaseous or liquid form. Causes of refrigerant leaks in your vehicle include physical damage, wear and tear over time, and escaping refrigerant even without a leak.
Freon (which is really just a particular brand of refrigerant) lasts forever. It's not like gas in car; it does not get “used up.” You see, your air conditioner's refrigerant system is a “closed/sealed system,” meaning that it does not allow refrigerant to escape in any way.
To answer your question, yes it's absolutely possible to drain refrigerant without a leak.
It's important to note that low refrigerant levels don't always mean a leak. We often receive calls at Watkins Heating & Cooling from customers with low Freon who had their HVAC system installed by other companies.
An AC unit typically cannot lose Freon (or refrigerant) without a leak. Refrigerant is a closed-loop system, and it should remain at a consistent level during normal operation. If the refrigerant level is low, it usually indicates a leak somewhere in the system.
Oftentimes, it's due to a compressor going out, or the motor slowing down, or a refrigerant leak.
It's important to remember that, while refrigerant shouldn't run out, it can. The only reason your air conditioner's refrigerant levels might change is if there is a leak in the copper coils or at connection points. This is a serious problem that will keep the AC system from working properly.
An electronic leak detector is one of the most reliable ways to check for a Freon leak. These detectors are designed to sense the presence of refrigerant in the air where a leak occurs.
If you simply need a top off of refrigerant, you can expect to pay anywhere from $160-$375. If you need a repair for the leak itself, you can anticipate a higher bill. For refrigerant leak detection and air conditioning repair you may pay anywhere from $550 to $1,600.
Most systems need Freon replacement anywhere from once every two to five years from a professional HVAC Contractor. The most significant exception to this rule is when there is a leak in the air conditioning system, which decreases the amount of refrigerant in an AC unit over time.
Many times, this is caused by a Freon leak due to a failed O-ring, seal or hose. Discovering these leaks early is important. Typically, early detection allows for the failing component to be repaired, and your air conditioner will be back to normal.
Our recommendation? Skip the stop-leak products altogether. Whether it's for your AC, power steering, or even tires, temporary fixes like these are rarely worth the risk. Instead, invest in a proper repair that will save you money and headaches in the long run.
Icy Coils. The evaporator coil is an important part of the AC system because it keeps the air cool. When you don't have enough refrigerant, the coils can develop a thin layer of ice. This weakens the system's efficiency and can damage the whole air conditioner.
Generally speaking, a properly maintained air conditioner can expect its refrigerant to last around 10-15 years or longer—depending on usage frequency and environmental wear and tear. To ensure your refrigerant lasts as long as possible, regular maintenance is key.
Yes! For clarity, the freon in the pipes of your AC is under pressure whether the unit is on or off, and the pressure pushes the freon out through the leak even if the unit is off.
Simple Methods
Visual Inspection: Technicians look for hissing sounds, water or ice buildup that can reveal a leak. Soap Bubble Test: By applying soapy water to pipes and connections, it allows you to see any bubbles that form at leak points.
If the system is still under warranty, most repairs are worth it. But if the warranty has expired or is invalid, repairing a leak can be very expensive. Plus, if it's out-of-warranty, chances are the unit has either been neglected or is too old to consider repairing.
Normally, this occurs at the location of the evaporator coil, but is not the only place a leak can stem from. If you lose enough freon from your HVAC system, your air conditioner won't work and will need servicing.

The average cost to recharge the Freon levels in an air conditioner unit ranges between $200 and $600. This number can vary, depending on the city you live in, the HVAC provider you choose, and the refrigerant levels in your air conditioner.
It's just circulated around your air conditioning system to cool your air. A leak in the system is the only way a unit could lose freon. If you believe there may be a leak, it's best to call a professional technician who is trained to determine if your air conditioner needs more freon.
Most ACs nowadays come shipped from the manufacturer with the exact amount of refrigerant that it will need for the duration of its life. So, unlike a car, your AC won't ever need to “fill up” on refrigerant unless something goes wrong with the system.
A Question of Supply and Demand
Therefore, maintenance people and air conditioning system specialists have less supply and are charging more for it. Some businesses have even reported thefts targeting their Freon canisters thanks to its newfound value. After 2020, R-22 won't be produced at all in the United States.
