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. If your refrigerant gets too low, there will simply not be enough “coolant” to cool the air as it is passed through your evaporator coil.
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.
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.
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.
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.
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.
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.
Sudden AC Performance Drops: Refrigerant tends to leak gradually over time, while AC compressors can stop working on a dime. While even small refrigerant leaks can cause large AC problems, sudden drops tend to indicate compressor failure.
Too little refrigerant also risks freezing the evaporator coil inside your home. The first problem with a frozen coil is the airflow restriction it causes, preventing air from circulating back out. The second problem is the water it creates once the ice melts, risking further damage around your AC.
If you're in need of a car A/C recharge service, look no further than Firestone Complete Auto Care. We offer an A/C Evacuate and Recharge, where we void the air conditioning system of old refrigerant and then recharge the system with new refrigerant.
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.
With proper maintenance, a car AC compressor can last an average of 10-15 years. Keep in mind that this is a general estimate and can vary based on factors such as the make and model of your car, how often you use the AC, and the quality of maintenance it receives.
Generally speaking, to have a shop properly change an AC compressor and related components, flush, and re-fill the AC system will run between $750 – 1500.00. Depending on the model and cost of the parts in general, this cost could be even higher.
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.
Low pressure in the system can occur when there is not enough refrigerant in the lines. This results in an inefficient cooling process, which can cause warm air to blow instead of cold. Refrigerant leaks could be caused by something as simple as a loose connection or a more serious issue like condenser failure.
Locate the high-pressure service port located near the AC compressor. Securely connect the freon gauge to the high-pressure service port. Start the car and set the air conditioning to the coldest temperature. Run the car for a few minutes and recirculate if necessary.
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.
Freon is contained within your vehicle's AC system, as in completely confined within, so Freon's loss isn't through consumption but through leaks that eventually develop within hoses and connections.
