Three Signs Your Truck's AC Unit Might Be Malfunctioning

Posted on

When it comes to problems with an air conditioner system, there are often a number of warning signs that indicate there is an underlying issue taking place. Being able to recognize these signs in your truck won't just allow you to get your system back in good working order, quicker, but it can sometimes also help you keep your repair costs lower.

Unusual Noises

Aside from the sound of the air forcefully pushing through your vents, your air conditioner shouldn't be producing much noise. If the opposite is true, there are a number of things that could be taking place. Take a knocking or banging noise, for example. This type of sound is often an indication that the compressor is malfunctioning.  

The compressor is the most important part of the system and works similar to a pump, pushing the cooling agent through. Addressing the issue promptly can be the difference between a repair and a costly compressor replacement.

Slightly Warmer Air

Sometimes the AC unit in your truck will produce a flow of air that is cool, but not quite cold. Don't think the system is just taking a few extra moments to heat up if this happens. Fortunately, the fact that the system is still producing air is a good thing, meaning the problem is likely a minor one.

One issue that can cause this is a problem with the cooling fans. If they aren't operating at full speed this can have an effect on how cool the air is. In some cases, a cabin air filter that is excessively dirty can get clogged and prevent the air from getting as cold as normal as well.

Reduced Air Flow

If you adjust the fan setting control on your truck's control panel and you can't seem to get the air to blow out at full speed, this might be an indication that there is a leak in the system somewhere, such as a coolant leak.

Unfortunately, diagnosing a leak isn't always as simple as looking under the carriage of the truck as the leak can sometimes be internal. Until the exact location of the leak is spotted, the issue can't be controlled and you will likely continue to experience a less than satisfactory flow of air.  

If you notice any unusual things taking place with your truck's air conditioner system, make sure you are taking it in for a proper diagnosis (at centers like Color Country Diesel Inc). Many concerns can quickly be resolved with timely attention.
