While the refrigerant in your vehicle can escape even without a leak, it's often not enough to cause significant issues unless you've failed to top up the refrigerant for years. When the lack of refrigerant becomes significant though, it can cause a number of problems, including an overheating driver in the summer sun.
No. Freon is a VERY stable molecule and won't break down over time. The only way it can escape from a cooling system is via a leak of some sort.
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.
If the refrigerant in your vehicle is low, there is likely a leak in the air conditioning system. Topping off the refrigerant may help get your A/C to blow colder temporarily, but the issue will likely return — which is why it's important to schedule an expert A/C diagnostic or service at Firestone Complete Auto Care.
The answer is that Freon should last forever unless you have a leaking system. Contrary to popular belief, units shouldn't need to be recharged every year. Many customers call our office because their AC system isn't working as it should.
Unlike oil changes, you should not need to change or refill your vehicle's AC freon. While trivial amounts of freon can be naturally lost over time, your air conditioner is a sealed system designed to keep freon recirculating—often for the full lifespan of your vehicle.
It's recommended that you recharge the air conditioning in your car every two years, to keep the cooling power at its highest. This keeps the refrigerant loss to around 14%. This means if we are recharging a system that holds 25oz you would only be purchasing 3.5oz of refrigerant.
An AC leak will lead to warmer air from your vents over time. In most cases this can be fixed with a proven stop leak additive to seal up any leaks. When it's time for an AC recharge, turn to AutoZone.
The actual leak repair depends on the component that's leaking. A simple O-ring can cost just a few dollars plus labour, but a new air conditioning line or condenser can cost hundreds of dollars. All-in, you can expect to pay $150 to $1,000 or more for a leak repair.
Common AC leak Locations. Since your AC compressor is mounted to your engine and your engine moves as you accelerate and decelerate, soft refrigerant lines have to be used to carry refrigerant to and from the compressor. These soft lines can often leak at the crimps or where the lines bend.
While it might be tempting to ignore a slight drop in cooling performance, the risks of running your AC system on low refrigerant are simply not worth it. From compressor damage to frozen evaporator coils, the potential for costly repairs grows with every mile you drive without addressing the issue.
Yes. Age eventually takes its toll on an air conditioner, so you could say a refrigerant leak is inevitable.
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.
If you own a brand new vehicle your refrigerant gas will last 3-5 years without you running into any major issues as long as you maintain a yearly car aircon service such as a 24-point diagnosis and Performance Check.
Perform a UV dye test on your air conditioner
Refrigerants are often mixed with a UV dye that will light up if detected under a black light. Thus, if you notice any fluorescent traces of the dye around various AC components, such as the hoses or fittings, it could confirm the presence and location of the leak.
🚨 Is it safe to drive a car with a freon leak? 🤔🚨 No, it's not safe. Over time, the components of the AC system can become worn and damaged, leading to freon leaks.
A professional AC recharge typically ranges from $150 to $300. This cost reflects the expertise required and the equipment used to ensure a proper recharge. On the other hand, a DIY recharge kit costs between $40 and $60. While this is a more affordable option, it requires careful handling to avoid issues.
AC repair costs can vary widely, depending on the cause of the problem and the type of vehicle. On average, car AC repair costs run between about $430 and $520. However, if you need a new compressor, you can expect to spend $1,300 to $2,500 or more.
While O'Reilly Auto Parts cannot recharge your vehicle's air conditioning system for you, we carry the parts, tools, and helpful resources to help you get the job done right.
If there's not enough freon, it won't engage and you won't hear that click. Another more serious symptom of low freon levels is a visible sign of a refrigerant leak. You can tell that it's freon if it looks like thin grease in liquid state.
Most cars hold between 28 and 32 ounces of refrigerant (or about 2—3 12oz cans), however larger vehicles and those with rear A/C will likely hold more. Check your vehicle manual for the system capacity for your specific vehicle.
Refrigerant can leak slowly from your car's air conditioning system over time, but recharging your car's air conditioning system so it once again blows cold air is an easy DIY task and takes just about 15 minutes.
