Your factory AC system helps keep you comfortable through all sorts of weather conditions. It's responsible for cooling, heating, and ventilating your cabin as you drive. That helps maintain your comfort, no matter the climate.

How Your HVAC System Works

The air conditioning system is composed of four major components. The compressor pressurizes the refrigerant and converts it to hot gas. The condenser then cools that gas to turn it into a liquid. The fluid passes through an expansion valve, where it transforms back into a gas, but at low pressure this time. Lastly, an evaporator uses a fan to cool the gas down quickly. That produces the chilled air that flows through the ducts, out of your air vents, and into the passenger space.

Heating is a much simpler process. Hot coolant gets drawn from the engine into a heater core. A fan blows over the core fins to send warm air into your car, truck, SUV, or van's cabin.

Eventually, though, your AC system can begin to have problems. Seals may have weakened. Hoses can degrade. The compressor may go bad.

How to Spot AC System Problems

Signs of AC system trouble include:

You're unable to maintain a consistent cabin temperature
The cabin atmosphere gets steamy
You detect the syrupy sweet smell of coolant

Genuine Mopar AC System Parts Are Best

If you experience any of these symptoms, check your cabin air filter first. If it's in good condition, inspect your HVAC system. If you find that a part does need to be changed, make sure to replace it with the best one for your vehicle. Authentic AC system parts made by your OEM are the best option for your model, since they were made specifically for it.
