Why doesn’t my air conditioner work when my car is idling?

Why does my AC only work when the car is moving?

This is because when you’re driving, air from outside of the car will still pass through the condenser. This helps to cool it down, even without the fan. But since the fan isn’t working, there’s no air to cool down the condenser when you’re stationary. Hence why the AC only blows cool air when the vehicle is moving.

Why does my AC go warm when idling?

Your AC system is low on refrigerant. Since the AC compressor is driven by the engine, it doesn’t pump as much refrigerant when you’re at a stop or driving slowly. If the system is low on refrigerant, it will show up as AC blows warm at idle and blows colder when the engine is running at higher RPMs.

Why is my AC only cold when Im driving?

If the fans don’t come on, the circumstance you have could occur. You might also have a low state of refrigerant charge. Other possibilities are that the compressor clutch is not cycling as intended or that the condenser might be blocked or dirty. And, of course, you could have a combination of these issues.

Why is my car AC cool but not cold?

The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.

Why is my car AC not blowing warm air?

Faulty heater cores and low or contaminated coolant levels often come hand in hand, and both issues may lead to your engine overheating and your heater not blowing hot air.

Why is my AC running but not cooling?

Condenser Unit is Blocked

If your air conditioner is running, but not lowering temperatures inside, one issue could be a blocked or clogged condenser coil. When operating correctly, the condenser fan draws air into the outdoor unit through the condenser coil to pull heat energy out of your home.

How often should you recharge your car AC?

Once every year or two is probably sufficient. Spring is a good time to do this. We advise you to schedule an AC recharge before your unit stops blowing cold air entirely. If you notice that the air coming out of your vents is not quite as brisk, give us a call.
