Common Car Air Conditioning Problems to Look Out For

Performance Trucks Auto (4)

When warm temperatures heat up outside, the last thing you want to deal with is a car air conditioning problem. Here are a few common car A/C issues to watch for this summer.

1. Inefficient Car Air Conditioning

When the air conditioning in your vehicle is set on maximum but you are only feeling slightly cool air, there are a few things that you should check. First, look for leaves, dirt or other debris that may be keeping the air from passing over the condenser. Also, look at the cooling fans to see if they are on when the A/C is running. Lastly, check the car’s refrigerant levels to see if you need to top it up.

2. Strange Smells

In the winter, fungi or bacteria can grow in your car air conditioning system while it’s not in use. If you notice strange smells when you begin to use the A/C again, you may need to have your A/C system flushed out completely.

3. Condenser Issues

Your car air conditioning system uses a condenser to cool the refrigerant vapors that leaves the compressor. If the condenser gets blocked by dirt or debris, the air conditioner will be diminished and inefficient. To clean a clogged condenser, you can use a flushing agent through the system. As a last resort, you may need to replace the condenser to get your car air conditioning system running well again.

4. Leaks

One of the most common problems found in a car air conditioning system is leaks. Check around the fittings, the hose manifolds around the compressor and the seals to see if any of these areas are loose.

If you find any of these car air conditioning problems in your car, you may want to take your car to a professional mechanic to get it checked out. In the long run, fixing a small problem can save you a lot of time and money rather than replacing the entire A/C system.

  1. I like what this article mentions about checking the condenser for any issues. I think this could be one of the sources of my AC problems as there seems to be a lack of power. It’s definitely something to keep in mind when taking in the car for a service.

  2. Thanks for this helpful information on common problems with air conditioning. It is time to start running the air conditioner in the cars again, and I noticed some problems with mine after the first use. I noticed that the air was a little bit strange smelling. It is good to know that when it has strange smells it might be coming from bacteria. I will be sure to have it fixed before the heat of summer is here. Thanks for the help!

  3. That’s good to know that air conditioner problems can be due to a bad, or clogged, condenser. The air conditioning in my Chevy hasn’t been working properly for a couple of months now, so I’ll probably have to take it in to an auto mechanic or some kind of service that offers air conditioning repair. Thanks for the information! I’m sure that it will help me get the proper repairs done for my air conditioner.

  4. Thanks for the tips. I had no idea the smell in my a/c was from fungus. I have noticed that it really stinks this year. It is kind of embarrassing when other people are in my car. I will have to go and get it flushed out. No more bad smells for me.

    • I had been noticing a strange smell in my car as well. I hadn’t thought fungus could be an issue, but sure enough that is what it was. I thought it was just my old car smelling bad.

  5. This is some great information, and I appreciate your point that condenser issues can cause problems with your car’s AC. My air conditioner has been having problems, and I think it’s because of blockage in the condenser. I don’t think I’m going to be able to clear it out, so I’ll definitely look into taking my car in to have that replaced. Thanks for the great post!

  6. I had no idea that bacteria could grow in the A/C system during the winter. It’s good to know that that could be a cause of the strange smells. Getting it checked before and after each season may be a good way to prevent against getting gross smells.
