When it's hot outside, and you're driving, you want cold air blowing from the A/C. If it's blowing warm air, you might need help from an auto mechanic to achieve comfort. Here are reasons why a car's air conditioner does not work properly.

3 Reasons Why a Vehicle Air Conditioner Blows Cool Air

1. Leaking Refrigerant

Your air conditioning system works by removing the interior moisture and hot air, which cools the vehicle's airspace. The refrigerant goes into the condenser, where it becomes a mist. This mist removes the hot air and moisture from inside the car, creating a cool environment.

A car A/C blowing warm air is often due to a refrigerant leak, which doesn't leave enough to do its job. This type of leak does not produce fluid puddles on the ground under your car, like an oil or antifreeze drip. An auto mechanic knows where indications of leakage appear, such as an oily residue around air conditioning hose connections.

2. Failing Compressor  

The compressor of your car's air conditioning system circulates the refrigerant, which takes heat away from the vehicle interior. When the compressor wears out, or suffers damage due to a clog in a filter or valve, it doesn't perform its job effectively. A faulty compressor prevents the refrigerant from circulating through your car properly, resulting in warm air. 

3. Faulty Electrical System

Your car’s electrical system might be causing the warm air problem. The fuses, wires, pressure switches, and relays work together to keep the system operating safely and efficiently. 

If any part becomes defective or reaches the end of its useful life, it might shut down the system intentionally. This response protects the system and vehicle occupants from harm. An experienced auto technician using the right diagnostic equipment can locate and correct the problem.
