Perhaps the easiest way to identify an issue with your air conditioner is if your vehicle is blowing warm or hot air. If your vehicle is too low on refrigerant, the evaporator core will not reach the optimal temperature for cooling. The air may start out cold, then blow warm. Or, it may never cool down at all.
One of the most obvious signs that your vehicle needs a Freon recharge is that your vehicle will be blowing warm air, even after your vehicle has been running for some time.
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.
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.
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.
What is the average cost of a car AC recharge? The average cost of a car AC recharge can range from $100 to $300, depending on the vehicle and location.
Your vehicle's air-conditioning not working is likely caused by a failing compressor or a freon leak. While these are the most obvious reasons for your air-conditioning not working inside your vehicle, it might be anything as simple as a bad belt or a dirty cabin air filter.
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.
If your system does not have enough refrigerant it is possible that a low refrigerant charge could be the cause. A low a/c system cause one half of your evaporator to work and the other half not to cool. This will cause the air coming out of some ducts to feel cool and the air out of other ducts to feel warm.
If you want the quick and easy answer, you should never run your air conditioner when it's low on refrigerant. Now, stick around to understand what happens if you unknowingly let your AC continue running with this problem.
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.
Warm Air from the Vents
If the compressor is fine, it will push cold air into the cabin of your vehicle. If you begin to notice warm or even hot air coming out of the vents, this is a clear indication that the compressor is not functioning properly.
One of the most obvious symptoms of low Freon levels is if your air conditioner is blowing warm or room temperature air. As we discussed, the air conditioning system in your vehicle operates by circulating this pressurized refrigerant. When the amount drops too low, it eventually affects performance.
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. Here's a breakdown of some of the most common car AC repairs and their average cost.
If the air still isn't cold after adding more Freon then there is probably another leak in the system. This is one of the most common issues for air conditioning problems. The compressor pressurizes the refrigerant and pumps it throughout the AC's necessary components.
Unusual Noises: Strange sounds, such as rattling, buzzing, or hissing when the AC is turned on, can signal problems. These noises might indicate a failing compressor or other damaged components in your AC system. Foul Odors: If turning on your AC emits a bad or musty smell, mold or mildew could be in your system.
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 the loss of refrigerant is a chronic, ongoing issue, have your car's AC system serviced by a professional technician at a dealership or repair shop. Keeping your vehicle in solid working order helps retain its value. By maintaining your vehicle, it helps if you ever need to sell or trade it in for a new one.
For instance, if you find oily-looking stains near the compressor, condenser, or hoses, you likely have a refrigerant leak on your hands. Refrigerants often appear oily. You may also see fluid on the ground underneath your car or in the driveway near where your car was parked.
Summary. A functioning AC compressor is necessary for a vehicle's air conditioning to perform at its best. Although replacing a faulty compressor can be expensive, having a professional perform the job and properly charge the system is always a good idea.
The short answer is: You should turn off your AC unit and unplug it from the power source. If the leak is small, you can try to repair it yourself using a sealant or tape. If the leak is larger, you'll need to call a professional for repairs. Once the leak has been repaired, have your AC unit serviced.
