Is my car air conditioning failing?

Air Conditioning

Summer is upon us and the temperatures are rising. It’s time to get your motor vehicle air conditioning (MVAC) system serviced and ready for the hot months ahead. Car air conditioning repairs are not always extensive or expensive, and it can make a huge difference in your comfort this summer. The AC experts at your local Southern California Ford Dealers are here to walk you through the most common air conditioning problems, and help you determine how to get the most out of your car’s climate control system.

Your car’s AC system isn’t complicated as it may sound. It is a relatively simple system, that relies on a compressor, refrigerant, and a condenser to cool the air being fanned into your cabin. As long as the AC has a proper refrigerant pressure, a working compressor, and a free-flowing circuit (no clogs), the AC should work well. If your vehicle’s AC isn’t blowing cold air, isn’t blowing any air, or is making strange noises, we are here to help.

The following is a list of the most common car AC issues, and what you can do to fix it.

Compressor Failure

Car AC systems rely on having a low-pressure side and a high-pressure side. Due to the fact the AC system must be pressurized accordingly to work to its full potential, a weak or failing compressor will cause the AC to blow warmer or not blow cold at all. You may also hear loud unusual noises coming from the compressor when the AC system is turned on. The compressor has a clutch inside that makes a clicking noise when its running. If you do not hear this clicking sound, it may be time to get the compressor inspected.

Low Refrigerant

Although your AC is a sealed system, refrigerant can break down or leak and need to be recharged and replaced. Low refrigerant levels or pressures will cause the AC to blow warmer temperatures. Recharging the system brings the AC back up to a proper pressure, with fresh refrigerant, so that it can start blowing cold air into the cabin. It’s critical that this is done by a trained professional, due to the hazardous nature of AC refrigerants.

Refrigerant Leaks

If your AC system is not holding pressure, there’s likely a leak. There may be an issue with a hose, O-ring, a bad fitting, or other system failure. Leaks can usually be traced by detailed inspections. Did you know there’s two types of refrigerant leaks – active and passive. Servicing the AC system in any way when there is a leak is pointless. You must fix all leaks in the system before recharging it. So, replacing components as needed is important.

Other Components

When we refer to the AC refrigerant system, we are only concerned with the components that hold, process, and contain the actual refrigerant. There are other potential issues that the AC can experience beyond refrigerant issues. Other problems can stem from electrical issues, switch failure, vent and blend door problems, and blower motor failure. Typically, problems with these components result in no air flow at all, lack of adjustable airflow, and low air flow.
