What Causes a Car to Hesitate When the AC is On?
Before we dive into the solutions, it’s essential to understand the underlying causes of a car hesitating when the AC is turned on. There are several factors that can contribute to this issue, including:
Low Refrigerant Levels
One of the most common causes of a car hesitating when the AC is turned on is low refrigerant levels. Refrigerant is a critical component of the AC system, and when it’s low, the system can struggle to cool the air effectively. This can cause the engine to hesitate or stall, particularly when the AC is turned on.
To diagnose low refrigerant levels, you can check the AC system’s refrigerant level using a gauge or by consulting your vehicle’s repair manual. If the level is low, you may need to recharge the system with refrigerant.
Clogged Air Conditioning Condenser Coils
Another common cause of a car hesitating when the AC is turned on is clogged air conditioning condenser coils. The condenser coils are responsible for dissipating heat from the refrigerant, and when they’re clogged, the system can struggle to cool the air effectively.
To clean the condenser coils, you can use a garden hose to spray them with water. You can also use a soft-bristled brush to gently scrub away any debris or dirt that may be clogging the coils.
Faulty Compressor Clutch
A faulty compressor clutch can also cause a car to hesitate when the AC is turned on. The compressor clutch is responsible for engaging and disengaging the compressor, and when it’s faulty, the system can struggle to cool the air effectively.

To diagnose a faulty compressor clutch, you can listen for any unusual noises or vibrations when the AC is turned on. You can also consult your vehicle’s repair manual for guidance on how to test the clutch.
Low Battery Voltage
Low battery voltage can also cause a car to hesitate when the AC is turned on. This is because the AC system requires a certain level of voltage to operate effectively, and when the battery voltage is low, the system can struggle to cool the air.
To diagnose low battery voltage, you can use a multimeter to check the battery voltage. You can also consult your vehicle’s repair manual for guidance on how to test the battery.
Solutions to a Car Hesitating When the AC is On
Now that we’ve explored the causes of a car hesitating when the AC is turned on, let’s take a look at some solutions to help you troubleshoot and resolve this issue. Here are some tips and techniques to help you get your car running smoothly and efficiently:
Check and Recharge the Refrigerant
If you suspect that low refrigerant levels are causing your car to hesitate when the AC is turned on, you can check the system’s refrigerant level using a gauge or by consulting your vehicle’s repair manual. If the level is low, you may need to recharge the system with refrigerant.
To recharge the system, you’ll need to purchase refrigerant from an auto parts store or a mechanic. Be sure to follow the manufacturer’s instructions for recharging the system, and avoid overcharging the system, as this can cause damage to the AC system.
Clean the Air Conditioning Condenser Coils
If you suspect that clogged air conditioning condenser coils are causing your car to hesitate when the AC is turned on, you can clean the coils using a garden hose and a soft-bristled brush. Be sure to gently scrub away any debris or dirt that may be clogging the coils, and avoid using high-pressure washes or harsh chemicals that can damage the coils.
