How to Fix Hot AC in Your Car

During the hot summer months, having a functioning air conditioning system in your car is vital. Unfortunately, sometimes the AC can stop working, leaving you sweating in the heat. If your car’s AC is blowing hot air, it’s likely due to one of these common issues. Here’s how to fix hot AC in your car.

Check the Refrigerant Level

The most common reason for hot AC in your car is a low refrigerant level. Refrigerant is the substance that cools the air in your car’s AC system. If the refrigerant level is low, the AC won’t be able to produce cool air. You can check the refrigerant level using a pressure gauge that can be bought at any auto parts store. If the pressure is too low, you can add more refrigerant.

Clean the Condenser

The condenser is the part of the AC system that releases the heat that’s been absorbed from the air. Over time, the condenser can become dirty and clogged, making it difficult for the system to release heat. You can clean the condenser using a garden hose or a pressure washer. Be sure to turn off the engine and let it cool down before cleaning the condenser.

Check the Compressor

The compressor is the part of the AC system that compresses the refrigerant and sends it through the system. If the compressor isn’t working properly, the AC won’t be able to produce cool air. You can check the compressor by turning on the AC and listening for a clicking sound. If you don’t hear the clicking sound, the compressor may need to be replaced.

Replace the AC Fuse

If your car’s AC is blowing hot air, it may be due to a blown fuse. The AC fuse is located in the fuse box under the dashboard. Check the owner’s manual to locate the fuse box and the AC fuse. If the fuse is blown, replace it with a new one of the same amperage.

Check the AC Belt

The AC belt is what drives the compressor. If the belt is loose or worn, it can cause the compressor to stop working. You can check the AC belt by looking for cracks or signs of wear. If the belt looks worn, it may need to be replaced.

Clean the Air Filter

The air filter is responsible for filtering the air that comes into your car’s AC system. If the air filter is dirty, it can restrict the flow of air and make it difficult for the AC to produce cool air. You can clean the air filter by removing it from the system and washing it with soap and water.

Check the AC Clutch

The AC clutch is what engages and disengages the compressor. If the clutch isn’t working properly, the compressor won’t be able to produce cool air. You can check the AC clutch by turning on the AC and watching the clutch engage and disengage. If the clutch isn’t engaging, it may need to be replaced.

Check the AC Sensor

The AC sensor is what tells the AC system when to turn on and off. If the sensor isn’t working properly, the system won’t be able to produce cool air. You can check the AC sensor using a multimeter. If the sensor isn’t working, it may need to be replaced.

Take Your Car to a Mechanic

If you’ve tried all of these steps and your car’s AC is still blowing hot air, it’s time to take it to a mechanic. A professional mechanic will be able to diagnose the problem and recommend the best course of action. Don’t wait until the heat becomes unbearable. Take your car to a mechanic as soon as possible.

Conclusion

A functioning air conditioning system is essential for staying comfortable during the hot summer months. If your car’s AC is blowing hot air, it’s likely due to one of these common issues. By following these steps, you can fix hot AC in your car and stay cool all summer long.
