It’s a situation that nobody wants, but likely everybody has faced. You get inside your car, only to feel hot air blowing from the A/C vents. There is nothing worse than a car A/C not blowing cold air. The good news is that there are a few common reasons why this may be happening. 

Here are the top reasons your car’s air conditioning might have stopped working suddenly. 

Low or Leaking Refrigerant

Low or leaking refrigerant is the most common reason you may have hot air blowing from your A/C vents. Refrigerant is responsible for cooling down the air that blows from your vents. If you’re experiencing warm air when you turn on your air conditioning, it could be because of low refrigerant levels. You may have low refrigerant levels due to a leak in your A/C system.

McCullough NAPA Auto Care can perform a refrigerant refresh for your vehicle. We will drain your A/C system of existing refrigerant and refill it with fresh refrigerant afterward. If the system still blows warm air after we flush it, we know it’s not due to a lack of refrigerant.

Broken or Blocked Condenser

The condenser uses airflow to re-cool hot refrigerant that comes through the front of your car. If the condenser gets blocked, your air conditioning system will stop blowing cold air and will blow warm air instead. The condenser is located at the front of the car and can become blocked with leaves or other debris. A broken condenser will need to be replaced. McCullough NAPA Auto Care has experience with installing replacement condensers.

Broken Compressor 

The compressor keeps refrigerant circulating through your A/C system. When a compressor breaks, refrigerant won’t circulate through the system. This will result in warm air blowing through the vents. Compressor issues can occur after long periods of inactivity, so be sure to run your A/C system every so often to keep it in good shape.

Faulty Cooling Fans or Problems with the Electrical System

Fans are necessary to keep your A/C system cool. If they aren’t working, your system won’t cool properly. Likewise, a frayed or blown fuse can prevent an A/C system from working as intended. These issues may be hard to spot for the untrained eye, but the McCullough NAPA team will happily inspect your system to see if this is the cause for your air conditioning system not blowing cold air.
