What Causes Your Car AC to Blow Hot Air?

“Why is my car AC blowing hot air?” There’s no one answer to that question as the air conditioning system in a vehicle consists of many different components. If any one of them is not functioning properly, the system won’t cool the air as intended. Here’s what to look at if you’re trying to figure out how to fix car AC not blowing cold air:

Compressor

• What It Does: The compressor cycles the refrigerant through your AC system.
• Best Way To Fix It: With so many moving components in a compressor, it’s typically easier to just have the compressor itself replaced.

Refrigerant

• What It Does: Refrigerant is a gas/liquid that cycles through your AC system. Its main job is to absorb heat and turn it into cool air.
• Best Way To Fix It: You’ll want to recharge AC in the car to fix the leaking refrigerant. However, refrigerant usually shouldn’t leak. Before you recharge AC in the car, we recommend you fix the leak first.

Condenser

• What It Does: Refrigerant circulates through the condenser to assist with cooling down your vehicle’s AC.
• Best Way To Fix It: A condenser usually runs into issues when there’s a blockage. Once a blockage has occurred, it’s too late to fix the issue, and you’ll likely need to replace the condenser.

Cooling Fans

• What It Does: Cooling fans will blow the hot air away from your vehicle.
• Best Way To Fix It: Cooling fans either become damaged from road debris or stop working because of a faulty fuse. To fix cooling fans, you’ll need to replace the fuse or replace the cooling fan, depending on the issue.

Electrical System

• What It Does: Many modern vehicles utilize a complicated electrical system to control the HVAC system in your vehicle.
• Best Way To Fix It: If your AC stops working, it’s usually because of damaged wires. Sometimes, you can repair just the damaged wire, or the whole wiring harness has to be replaced.
