Air Conditioning
An air conditioning system in a car is a system that cools and dehumidifies the air inside the car. It has five main components: compressor, condenser, evaporator, accumulator/receiver drier, and expansion valve/orifice tube. The compressor squeezes refrigerant gas, which goes to the condenser to be cooled and turned into a liquid. The liquid refrigerant goes to the evaporator, where it removes heat from the air inside the car, making it cooler. Depending on the vehicle design, it will have either an accumulator or receiver drier, but both are designed to remove moisture from the refrigerant and filter the system. The expansion valve controls how much refrigerant flows, and the process starts again. This helps keep you comfortable and cool inside your car on hot days.
Air conditioning parts can wear out or stop working overtime, causing the system to stop working or become less efficient. If you need air conditioning parts to fix your car's A/C system, check out Advance Auto Parts.

If your car's A/C is not blowing cold air, it could be due to several reasons such as a faulty A/C compressor, low refrigerant levels, or an electrical issue.
Here are some common causes:
- Low refrigerant levels: If the refrigerant levels in your A/C system are low, it will not be able to cool the air as effectively or might not cool at all. This could be caused by a leak in the system or normal wear and tear over time.
- Dirty cabin air filter: If the air filter in your A/C system is dirty or clogged, it can restrict airflow and make it harder for the system to cool the air.
- Faulty compressor: The compressor is the heart of the A/C system, and if it's not working properly, the system won't be able to cool the air effectively.
- Clogged condenser: The condenser is responsible for releasing the heat absorbed by the refrigerant, so if it's clogged with leaves or other debris, the system won't be able to cool the air as effectively. Electrical problems: Faulty electrical connections, pressure switches, or electric fan can cause the A/C system to not function properly.
