5 Signs Your Diesel Truck Needs Heating and Cooling Services

There are more than 6.6 million diesel trucks on the road today. If you’re one of those people, you know that you have a car that will be able to get the job done. To keep things going, your diesel truck needs to be in perfect condition. 

A key part of keeping your truck running is your diesel truck AC. A bad AC system can cause problems down the road, like engine trouble.

It can be hard to tell when your truck needs to receive heating and cooling services. Keep reading if you’re trying to figure out if your diesel truck heating and cooling system is working properly. 

1. Smoke Under the Hood 

Smoke under the hood can be a signal for a variety of different truck problems, and diesel truck AC problems are one of them. If you see smoke coming from the hood of your car, stop driving and pull over immediately and get out of your car. 

The job of your AC compressor is to cool down hot areas. When that part is broken, your compressor isn’t able to keep temperatures down. This can lead to smoking from being overheated. 

Another AC problem that smoking under the hood is a sign of is your AC system is empty and in need of oil. The smoking is caused by the AC continuing to run with nothing to fuel it. 

2. Unfamiliar Noises

When you turn on your diesel truck air conditioning, the only thing you should hear is the smooth sound of air flowing out. But if you turn it on and hear rattling, banging, or both, you need to visit heating and cooling services as soon as possible!

The noise could be caused by a part of your AC system needing to be replaced. A damaged piece could be hitting or rubbing against other pieces, possibly causing more damage. 

Your AC unit involves a lot of open piping. Leaves, rocks, sticks, and other debris can build up in your system over time. This debris will bounce around causing possible damage and making that noise until you get it cleaned out. 

3. Bad Smells 

As the air flows from your AC unit into the body of your car, the last thing it should make you want to cover your nose. A stinky car can make driving a chore, and air fresheners can only do so much. If the air smells when it comes out of your diesel truck AC, you need to make repairs. 

The bad smell is usually caused by a dirty filter that needs to be cleaned or replaced. It’s also possible that mold is growing in your AC system. If this is the case, heating and cooling services can give it a thorough cleaning to get it back in peak condition. 

When bad smells build up in the body of your car, you need to be careful. Depending on the source of the smell, it can cause health issues to develop. 

4. No Air Comes Out

Your diesel truck heating and diesel truck air conditioning have a serious job to do: make you feel comfortable in your truck! The last thing you want to happen is driving around all day without a working diesel truck AC system. 

If you turn on your AC unit and nothing comes out, that is a tell-tale sign that you need to visit heating and cooling services. When no air comes out of your vents, there is a problem with the HVAC system in your truck. 

The HVAC system in your truck has a hard time running when there is no refrigerant. Checking refrigerant levels is a quick way to see if that is the source of your problems. 

Your cooling fans could also be damaged. If your cooling fans are damaged, they aren’t able to pull the cold air through the radiator.

The vents themselves could also be clogged. A clog will prevent hot or cold air from traveling throughout your system. The nice thing about clogs is that they can usually be repaired quickly, so you’ll be back on the road in no time! 

5. The Air Temperature is All Wrong

When it’s sweltering outside and you get in your car, the last thing you want is for your AC to not be as cold as it should be. If you turn your AC up all the way and the air comes out cold, but not as cold as it should be, you need to book a visit with heating and cooling services. The same goes for when you turn on your diesel truck heating and the hot air isn’t hot enough. 

A leak in your cooling system is the biggest source for the air temperature not being correct. When your system loses refrigerant, it can be difficult to cool the air to the level you need it. 

Refrigerant can leak both internally and externally. External leaking will usually result in bright green or orange fluid underneath where you parked your car.

Internal leaking can result in refrigerant being burned in the combustion chamber. If this is happening, your exhaust smoke will come out white.
