Car Sputters when Ac is On

Ac may be the season of love, but it can also be the season of headaches. If your car is sputtering and not starting when you turn on the AC, chances are your AC unit is not working properly. Here are four common causes and how to fix them.

What to do if your car sputters when you turn on the ac

If your car sputters when you turn on the AC, there are a few things you can do to try and fix the issue.

First, make sure that the AC unit is plugged in and working properly. If the AC unit is not plugged in or is not working, then it may be necessary to replace it.

If the AC unit is working properly, then it may be necessary to clean the AC unit’s filter. To do this, open the hood of your car and remove the air filter. Remove any dirt or dust that may be blocking the air flow through the filter. Once you have cleaned the filter, replace it and reattach it to the air intake tube on the side of your car.

Causes of car sputtering when ac is on

When your car sputters when it’s turned on, there are a few potential causes. Unfortunately, not all of them are easy to fix.

One common culprit is dirty air filters. When the filters can’t catch all the dirt and debris, the engine has to work harder to get the air flowing through it. This can create problems with fuel economy and emissions, as well as with your car’s performance. It’s important to regularly clean your air filters, and to replace them if they start to become worn.

If you’re experiencing sputtering when ac is on, another possibility is a faulty AC compressor. A compressor that’s not working correctly will struggle to produce enough cold air, which can cause your car’s engine to sputter and misfire. If you notice that your AC is starting to give you trouble, it might be worth having it checked out by a mechanic.

How to fix car sputtering when ac is on

If your car sputters and makes a weird noise when the AC is on, there are a few things you can do to fix the problem. One common cause of car sputtering when the AC is turned on is debris blocking the air filter. To clean the air filter, remove the cover and unscrew the filter. Remove any dirt, dust, or anything else that may be blocking the air flow. Once the air filter is cleaned, reinstall it and screw it in place. If debris still causes car sputtering when AC is on, you may need to replace the air filter.


There could be a few things causing your car to sputter when the AC is turned on, and if none of them seem to be the culprit, it might be time for a tune-up. Have your mechanic check all of your emissions sensors and hoses as well as the gas tank and lines in order to rule out any potential issues. In most cases, an exhaust system tune-up will also clear up this issue. If all else fails, have a technician take a look at your AC unit itself.
