Call Ice Cold Air, we’ll live up to the name.
In Florida, we are blasting the AC in our cars practically every day, all year-round. We have a love-hate relationship with the heat.
Fall is a common time for your car’s AC to go out, and we don’t want you to have to deal with the discomfort of not having AC for long – but we’ll be honest, diagnosing AC problems can take time.
Ice Cold Air is here to help with any car AC issues! If you’re experiencing any of the problems below, call us for an appointment to get your car back to cool. We care about our customers – your comfort and your safety.
What Makes Your Car AC Work?
The air conditioning system in your car has several components. These include:
- a compressor that is driven by the engine,
- an expansion valve that regulates the flow of refrigerant. Refrigerant is a fluid that turns into a gas and back to liquid form, flowing throughout the system.
- and two heat exchangers including the evaporator and condenser.
Now, let’s dive into some common AC problems with your car.
Problem: No Cold Air from the AC
This issue is typically caused by a refrigerant leak. Your AC relies heavily on refrigerant to cool the vehicle. Without enough refrigerant, the other pieces of the AC will be non-functional.
A leak can happen at any time, but it is most often caused by a hole in one of the connections. These leaks can be particularly difficult to catch because refrigerant evaporates when exposed to the environment.
Solution: For a refrigerant leak, you need to call a professional. An expert will add a fluorescent leak tracer dye and refrigerant to the system. From there, the technician you’re working with will run the AC and use a blacklight to identify where the leak is coming from to begin repairs.
Problem: No Air Coming from the Vents
This issue isn’t as clear as hot air coming through the vents. A knowledgeable professional needs to eliminate possible causes by checking several components of your air system first.
The things we would be looking for include:
- A blown fuse or bad relay – if the ventilation fuse blows there will be no power to the blower motor. This prevents air from blowing through the vents. A bad relay takes a small electrical current and uses it to regulate a larger current needed to power the ventilation system.
- Damage to the blower motor or blower resistor– the blower motor pushes air through the car. Blower motors that are malfunctioning due to wear or age will prevent air coming through the vents. The blower resistor works with the blower motor to control the level of how much air is produced to flow through the vents based on your preference.
- Blocked air intake– your vehicle has two areas where it intakes air through the ventilation system. If either of these areas is blocked from a clogged filter or with debris, your vents may blow little to no air.
- Damaged belts and hoses – the AC system is equipped with many belts and hoses. Any sort of leak, detachment, or blockage will prevent air from flowing.
Solution: A tech will replace fuses and/or the relay first. If the issue continues, a tech will test the other components related to the ventilation system.
Problem: Air Does Not Get Cold
This problem is typically caused by low refrigerant. If there is not enough refrigerant in the system, the pressure is reduced and it prevents the clutch from triggering the compressor to begin the AC cycle. If there is enough refrigerant, this problem could be caused by a blocked or failed condenser or a failed clutch switch.
Solution: If you’re experiencing this problem, you need to bring your car in to be looked at by a professional to test all of the components to look for blockages, damage, or failure.
Problem: AC Smells Like Mildew
When you turn on your AC and there’s the smell of mildew – that means you have a growth of bacteria in your system. This is common for vehicles that don’t often use the AC, are older, or frequently use the maximum setting. The extra moisture can cause bacteria, mold, fungi, and other growths behind your dashboard that comes through your vents.
Solution: The quickest and easiest way to combat this is to replace your air filter. If the problem persists, let a technician know and they can add an anti-bacterial solution to kill mold and other contaminants in the system.
Problem: Car AC Makes Noise When Turned On
Anytime your car makes a sound that wasn’t there before is usually a bad sign. AC’s are relatively quiet when in use, if you hear rattling, banging, or other unusual sounds – it’s normal to feel anxious about what is causing the issue.
Solution: Bring your car in to Ice Cold Air and we can give it a listen. The problem could be as simple as debris within the system, or it could be a larger sign of failure. Our inspections are fast and easy, and we’ll work with you to solve any issue with your car.
Problem: AC Goes from Cold to Hot
If your AC suddenly goes from cool to hot – that is a big problem. The expansion valve that dispenses the correct amount of refrigerant may have failed. A blocked expansion valve stops the refrigerant from reaching the evaporator and if moisture is present – it will cause the valve to freeze.
Solution: Take in your car to get inspected and tested. A trained technician will be able to find, identify, and solve the problem – whether it’s a blockage or a malfunction.
