Why Isn't My A/C Blowing Cold?

There is perhaps nothing more frustrating than riding around in a hot car on a sweltering day because your air conditioner conked out on you. If you've ever experienced this kind of situation, you know how miserable it can be. If your A/C is not blowing any cold air, it could be due to quite a few different factors; below are some of the most common culprits, as well as some tips to help you get them fixed.
Your air conditioner may need to be recharged
One of the most common reasons why an air conditioning system stops pumping out cold air is because it needs to be recharged. This is one of those routine maintenance items that often goes overlooked, but is immediately noticeable when it has been neglected. While it is possible to recharge your A/C yourself, it is preferable to have a professional handle the job.
Your air compressor may not be functioning properly
If there is any kind of issue with the compressor's circuitry or clutch, the unit will not engage, leaving you without any cool air. In most modern cars, the A/C system is controlled by some type of on-board computer system, which will typically shut the entire A/C system off if any type of engine problem is detected. In order to get everything working properly again, you will more than likely need to have the unit serviced by a qualified auto technician.
You may have a Freon leak
Freon is the refrigerant that actually cools the air blowing from your A/C unit. Over the course of time, small amounts of Freon can leak from your A/C lines, resulting in decreased performance. This will eventually lead to a shortage of Freon in your A/C system, which makes it more difficult to cool the volume of air that is being circulated in the vehicle. Many times a Freon leak will be very slow, which makes it somewhat hard to detect without a professional inspection. If you get your Freon refilled but then begin to lose your cold air within only a couple of weeks, there's a good chance that you have a substantial leak somewhere in your system. In that case, it is a good idea to have all of the hoses and system components of your A/C system inspected and serviced to ensure that no leaks have emerged.
If your A/C system is not blowing any air at all, this could be due to a malfunctioning fan, or a blower motor that has gone bad. No matter what the particular "symptoms" may be, the best move to make would be to have your A/C system serviced by experienced professionals. You can take your vehicle to a local Hogan & Sons Tire and Auto auto shop, and a certified auto technician will take care of the issue and have your cool air flowing again in short order.
