Why Does My Car Run Slow When the AC Is On?
There are several possible reasons for a car engine to lose power and acceleration when the AC is on. These include a clogged A/C condenser, a bad fuel pressure regulator, a clogged air filter, a faulty AC compressor, and a low coolant level.
It is normal for there to be a brief initial loss of rpm when the AC is turned on, as the AC clutch adds extra strain on the engine. However, the car's computer should adjust the idle speed to compensate for this. If the engine loses over 200 rpm and the idle speed does not rise again, then there may be a problem.
Is the slow performance of your car related to the AC system?
Activating the AC in your car results in a decrease in speed due to a reduction in revolutions per minute (RPM), impacting acceleration. The engine experiences strain from the additional load caused by the AC, leading to a decrease in speed. It is important to note that the AC does indeed impact the power of your car's engine. As previously mentioned, different components of the car utilize energy from the engine in order to function optimally. For example, during highway driving, the acceleration of your car consumes 20 horsepower from the engine.

How does air conditioning affect the engine?
The impact of air conditioning on a car's engine can be observed by monitoring the RPM (revolutions per minute). When the car's AC is switched on, the engine's RPM will increase in a clockwise direction, indicating a rise in activity. This is a direct result of the compressor being activated. The RPM serves as a standard measurement of a car's performance.
Acceleration may be slower when the AC is turned on due to the additional strain placed on the engine. This is supported by factual evidence.
Does AC affect car performance?
When the air conditioning system is on, the engine needs to exert more effort in order to operate the compressor and condenser fan. As a result, the engine has less power available for accelerating the car. This can lead to a slight reduction in acceleration while the air conditioning is running. However, in most cases, this effect is not significant enough to be noticeable by the driver.
According to an article on autocornerd.com, there are seven possible causes for the loss of power and acceleration in a car's engine when the air conditioning is turned on.
Can the AC system put extra strain on the engine and cause sluggishness?
Using the air conditioning (AC) in a car places additional pressure on the engine, affecting its performance. The AC puts strain on the engine, thereby decreasing its power and acceleration. Consequently, the engine needs to produce more power to overcome this strain.
The operation of the AC compressor in the engine compartment actually generates more heat. This is because the engine experiences increased strain from operating the AC compressor, which is driven by the serpentine belt. As a result, the engine generates heat at a higher rate.
The presence of the car's AC system places excess strain on the engine, leading to an increased generation of heat. Consequently, the coolant system has to work harder to remove this excessive heat from the engine.
