Potential Problems

There are a number of reasons why your car’s AC is not blowing cold air. This is only a shortlist of some potential reasons. Keep reading to find you what you can do.


It Needs Recharging

The most common reason an AC is not blowing cold air is it needs recharging. The refrigerant can actually be recharged by yourself, but if you don’t want to do it you can come to one of our expert professionals and get your cold air blowing again very quickly.

There’s A Freon Leak

Freon is the gas that makes the air cool, and if there’s a leak in the AC system, it will eventually run out. AC systems today are very sensitive and require a very specific amount of freon to work properly. The right way to check for the correct volume of Freon in your AC is with a charging machine. This will remove all freon from the system first, then fill it with the right amount for proper operation. A freon leak can happen very very slowly. So if you add more freon and then don’t have cold air a few weeks later, you may need to check the hoses and replace them.

The AC Compressor May Not Engage

This issue can happen because of a variety of conditions. A failure in the AC compressor can happen when there’s an electrical fault in its circuit or clutch. This can result in freon being low or in the car overheating. Cars today are controlled by computers and the AC system is one of the first things to be turned off by the computer when it senses a problem with the engine. Often, the part that is malfunctioning has to be replaced by a certified technician.

The Blend Air Door Is Stuck

Inside your vehicle’s ventilation system there is a small hatch called the blend air door. When you turn your AC from heat to cold, this door has to change to draw in the cold air. If it doesn’t, it will be drawing heat and blowing it. Again, this needs to be a job for a mechanic.

You Can Feel Cold Air, But It’s Not Flowing

This can mean that the AC fan is no longer working. Fixing it could mean changing a wire or replacing the fan unit. Again, you can’t really do this yourself, it requires removing the dashboard and reaching all of the components. You should have a professional technician take care of it.


Other Problems

Your vehicle’s AC system is very complicated and some easy fixes such as adding freon can be done by you, but there are more difficult problems that only a certified technician can fix. In some cases, a problem can be a sign of more severe issues, but repairing the AC is a very simple job usually, even if a mechanic needs to take care of it.
