Possible Reasons Why Your Car’s AC Isn’t Blowing Cold Air

Your AC is an essential system for your comfort on the road, so if it’s blowing warm air, it’s a cause for concern. Below are some potential reasons your car’s AC is not blowing cold air.

Refrigerant Leak

Often, when a car’s AC is not blowing cold air, it’s a refrigerant leak causing the issue. Refrigerant expands and contracts while it removes heat and humidity from your car’s interior. All other AC components rely on the proper amount of refrigerant. Contact our certified technicians to locate the source of a refrigerant leak. Once we find the source of the leak, we will quickly fix it so you can continue enjoying cool air during your commute.

Broken Condenser

The condenser in your vehicle keeps your refrigerant cool. If the condenser is malfunctioning, the process will break down. That’s why you’ll feel hot air coming from your AC instead of cool air. The condenser is in the front of your car, between the grille and the radiator, and it requires air to flow through the grate to produce cool air. If the condenser is clogged with dirt, air won’t reach it, and the refrigerant won’t chill the air.

Broken Compressor

Another potential reason the AC is not working in your car is an issue with the compressor, which circulates the refrigerant through the AC. If the compressor isn’t working properly, the antifreeze won’t reach the condenser for cooling. Typically, compressor issues happen after extended periods of non-use, like during the winter when you don’t turn on your air conditioning. 

Electrical Problems

A blown fuse or frayed wiring can cause AC not to work, even if the other AC systems are functioning correctly. Diagnosing and correcting the electrical problem requires a professional, starting with a complete visual inspection of your fuse box, wires, and electrical system.
