Does the AC make a car slower?
Unless the car engine is sufficiently big, the energy required to run the AC becomes a significant part of the engine power. Therefore, less power is available to run the car. Hence the slow down.
Why does a car slow down when the air conditioner is on?
The compressor requires 5–10 horsepower to pump the fluid. Say your car has 100 horsepower to get you down the road, when the AC turns on the compressor uses 5–10 horsepower and now your car effectively has less horsepower to get you down the road, which is why you slow down.
Is it better to run an air conditioner at high or low speed?
On high temperature low humidity days running the fan at a higher speed will allow the air to cool down faster and reduces the air conditioner’s ability to dehumidify.
Why does car RPM drop when air conditioner is on?
Cars RPM drops when the AC is turned on because the AC compressor has kicked in. After the interior cools off, the compressor will cycle on and off.
What to do if your air conditioner fan is slow?
You can still hear the compressor running if this is the cause of the slow air conditioner fan.

Why does my air conditioner get cold while driving?
One of the most common causes of the symptom you’re describing is when you have a bad or failing AC high pressure hose. The high pressure hose is designed to increase and decrease AC pressure during different driving conditions, since the AC drive belt will increase in speed as the vehicle accelerates.
On high temperature low humidity days running the fan at a higher speed will allow the air to cool down faster and reduces the air conditioner’s ability to dehumidify.
Why does my AC take so long to cool down?
Solution: Well, you can’t change the weather. But if everything is working correctly in your AC, that means it’s just one of those 1%, super hot days. If your filter looks like the one on the right, it’s dirty and it’s time to replace it. Believe it or not, but even a dirty air filter can prevent your AC from cooling your home.
Why is my AC blower running very slow?
If the bearings are dry, then you need a new blower motor. (unusual) Since you have a heat pump, if it is a higher performance model it may have an electronic blower speed control that is supposed to automatically slow the blower when it is very cold outside to ensure an adequate warm air temp inside.
