To check if your car AC is working properly, start by turning it on and feeling the air coming out of the vents. It should feel cold and refreshing, indicating that the system is cooling the air.
Put a thermometer inside the air vent. Run the A/C on maximum. Have it on recirculate and highest fan speed. The temperature after 10 to 15 minutes should be between 38 to 40 degrees F.
The most likely reason your air-conditioner isn't cooling is the car's air-conditioner is leaking. The car's AC system needs freon to lower the ambient air temperature and creates some needed cold air. Whenever there is a freon leak on your car there is no way to cool the air.
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.
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.
There are a number of reasons why your air conditioner might be running but not cooling. It could be an issue with the thermostat, the compressor, or the evaporator coils. Or, it could simply be clogged with dust and debris, which is preventing it from working properly.
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.
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.
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.
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.
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.
Common Reasons AC Doesn't Run Cold
The most common causes of broken air conditioning leaks or compression issues. If you are feeling cool — but not cold — air, the issue could be a clogged filter, a problem with the cooling fan, signs of radiator trouble, or it could simply mean it's time to recharge your AC.
The good news is that recharging your air conditioning system is a relatively simple process — but it's essential to do this regularly. 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%.
On average, replacing a car AC compressor can range from $500 to $1000, making it a significant investment for many drivers. It's important to compare prices from different auto shops to find the most competitive rates for this essential repair.
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.
In order to maintain your car's air conditioning, it is highly recommended that you have it regassed annually. Regassing involves evacuating the refrigerant gas from your air conditioning, testing for leakages, then re-filling and pressurising the system.
If the refrigeration circuit seems to be working (refrigerant in the system, compressor running and building pressure), but there is still no cooling, the problem might be an obstruction in the orifice tube (located in the high-pressure hose between the condenser in the front of the radiator, and the evaporator located ...
