All of these can be checked by observing the pressures around the system both before and after the compressor and all the other components. Check your compressor for proper operation, clogs in your system and the proper amount of refrigerant. The refrigerant in your system also needs to be able to flow properly through the system. Check the front of your vehicle for debris, the engine cooling fans for proper operation, and your cabin air filter for debris and dirt. Since there are two components that require air to be moving through them, the evaporator and the condenser, it is possible one or both of these are clogged and not getting the proper air flow.

Getting to the root of the problem can take some time and effort, but we have simplified the process by providing you with the most common A/C problems along with how to resolve these problems once they’re discovered. If your car’s air conditioner isn’t working properly and is blowing hot air then one of these systems isn’t doing its job properly. The dryer is where any moisture is removed from the refrigerant, the refrigerant is filtered to make sure it all enters the compressor as a gas, and the oil for the system is equally distributed through the refrigerant passing through.

There are a few other components in the system like temperature and pressure sensors, hoses and the dryer or accumulator. Now the cold, low-pressure refrigerant can return to the evaporator to cool it and along with it, more air keeping your car comfortable.

The process of liquids and gases getting cold during expansion is a scientific phenomenon you can prove by using an entire can of spray paint in one sitting and seeing how cold the can gets. The expansion valve is a simple device that takes advantage of the fact that quickly expanding liquids and gases get cold. This high pressure, now cooled, refrigerant is then allowed to expand quickly as it passes through an orifice or expansion valve. On most cars the condenser is actually in front of the radiator and gets cooled first to make sure your A/C system gives you consistently cool air. The condenser is cooled by ambient air in the front of your car just like the coolant in the radiator is cooled. This hot refrigerant is then cooled down by running it through the condenser. This is accomplished by first compressing the refrigerant to a high pressure which also heats it up to a high temperature. This warmer refrigerant now needs to be cooled back down so your A/C system can continue to operate. As the cold refrigerant passes through the evaporator it absorbs the heat in the air which warms up the refrigerant. Most cars today use a refrigerant called R-134a which is a special refrigerant designed to work at the temperatures and pressure standard in a car’s A/C system. These coils are cooled by cold refrigerant flowing through them. Most systems are designed to blow very cold air, between 32 and 40 degrees! These cooling coils, called the evaporator, is where the actual cooling of the air happens. This cools down the air before it gets blown out of the ventilation system into your car to keep you comfortable. In technical terms, the cool air is created by blowing air from either outside your car, or from the cabin over cold coils. Instead of actually creating cool air, it instead removes the heat and moisture from the air inside of your car, leaving you with cooler feeling air. Your car’s A/C system is one that operates a little differently than you might think. In this article, we’re going to look at how your Car’s A/C creates the cold air so you can more accurately diagnose what’s going wrong. If your air conditioner blows warm air, it is important that you get it looked at as soon as possible so you can continue driving in cool comfort. When you only get hot air instead of cold air, it can be frustrating and extremely uncomfortable. It’s something that we often take for granted until it’s a hot day and your car’s A/C is not working. The air conditioning system in your car is designed to cool down the air in the cabin of your vehicle to keep you comfortable on a hot day.
