What causes air conditioner to stop working?
As the owner of Kevin's Autos, I understand how frustrating it can be when your car's air conditioning system fails, especially during the hot summer months. A malfunctioning air conditioner can make your driving experience uncomfortable and even unbearable. In this article, we will explore the common causes of air conditioner failure in vehicles and what you can do to prevent it.
Common Causes of Air Conditioner Failure
There are several reasons why your car's air conditioning system may stop working. Understanding these causes can help you diagnose the issue and seek the appropriate repairs. Here are some of the most common culprits:
- Refrigerant Leaks: One of the most frequent reasons for air conditioning failure is a refrigerant leak. The refrigerant is essential for cooling the air, and if there is a leak, the system cannot function properly.
- Compressor Issues: The compressor is the heart of the air conditioning system. If it fails, the entire system will stop working. This can be due to electrical issues, wear and tear, or lack of lubrication.
- Clogged Condenser: The condenser is responsible for dissipating heat from the refrigerant. If it becomes clogged with debris or dirt, it can hinder the cooling process.
- Faulty Electrical Components: Electrical issues, such as blown fuses or faulty relays, can prevent the air conditioning system from operating. These components are crucial for the system's functionality.
- Blocked Cabin Air Filter: A dirty or clogged cabin air filter can restrict airflow, making it difficult for the air conditioning system to cool the interior of the vehicle effectively.
Preventive Measures
To avoid air conditioning problems in the future, consider the following preventive measures:
- Regular Maintenance: Schedule regular maintenance checks for your vehicle's air conditioning system. This can help identify potential issues before they become major problems.
- Check for Leaks: Regularly inspect your air conditioning system for any signs of refrigerant leaks. If you notice any, have them repaired immediately.
- Replace Filters: Change your cabin air filter as recommended by your vehicle's manufacturer to ensure proper airflow.
- Use the AC Regularly: Even in cooler months, run your air conditioning system periodically to keep the components lubricated and functioning properly.
By understanding the common causes of air conditioner failure and taking preventive measures, you can keep your vehicle's air conditioning system running smoothly. If you experience any issues, don't hesitate to contact us at Kevin's Autos for professional assistance!
Frequently Asked Questions
Where is the AC reset button located?
In AC systems, the air conditioner reset button is on the outside unit's lower edge, typically close to the ground. Some models have the reset button located behind the service panel, which may require tools to remove. Reset buttons are usually red or yellow with a clear “reset” label.
What is the first thing to check when the AC stops working?
Make sure it has power (check outlet if a window unit, check circuit breaker if hardwired). Check thermostat battery if accessible (some wall units use a battery). Check if filters are clogged. Check outside duct for obstructions.

- 3) Check the Circuit Breaker.
- 4) Check the Indoor Shutoff Switch.
- 5) Check the Outdoor Shutoff Switch.
- 6) Find the AC's Reset Button.

Why did my AC stop working all of a sudden?
Simple Causes for an AC Unit Suddenly Stopping
Here are a few common causes: Circuit Breaker: Your AC unit may stop working if the circuit breaker has tripped. Resetting the circuit breaker might solve the problem. Thermostat Settings: A wrongly set or faulty thermostat can also cause your AC to stop working.
Should I turn off AC if it's not cooling?
When you notice that your air conditioner isn't cooling, your first action should be to turn it off. This might seem counterintuitive—after all, you want your home to be cool. However, continuing to run an AC that isn't effectively cooling can cause further damage to the system.
How do I know if my air conditioner needs Freon?
You might feel warm air flowing through the vents, or you might notice that your AC is weaker than it used to be. If air flow seems fine, but the air coming up isn't cool, then you likely have a refrigerant problem.
How do I know if my AC fuse is blown?
AC Fuse Blown Symptoms
- Strange sounds are coming from your air conditioning unit.
- Your circuit breaker keeps tripping.
- Your unit smells like it is burning or gives off the smell of exhaust.
- Water is leaking from the unit.
- Your system freezes up or only works on the highest setting.
Do all outside AC units have a reset button?
Not all air conditioning units have a reset button, but if yours does, it's typically located on the outdoor unit. Here's how to locate it: Turn Off the Power: Before you search for the reset button, ensure the power to the unit is turned off for safety reasons.
How much does it cost to put freon in an air conditioner?
$200 to $400
Residential Air Conditioner Freon Refill Cost
Most homeowners will pay in the range of $200 to $400 for a refill, depending on the type and size of their HVAC unit. If you own a larger r22 unit, you may have to spend $600 or more. To break this down for you, a 25lbs unit of r410A costs anything between $100 and $175.
How many years does Freon last in a air conditioner?
around 10-15 years
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.
