Why does my car struggle to accelerate when the AC is on?
by
The reason for this issue is that your air conditioning system is directly tied to your motor—so as you cool off you’re effectively applying some of your horsepower when you set your climate controls to cold air. However, in most cases, this is only 5-6 horsepower.
Your car’s AC will obviously take power from the same source your whole car takes, and that is the engine. The additional pressure of the air conditioning system puts load on the engine.
Does AC cause power loss?
If the AC creates a sudden increase in draw on amps, it can cause a circuit breaker to trip and cut off electricity to the system. Check your home’s electrical panel to see if any breakers have tripped. Reset them, then turn the air conditioner back on.
Bad Belt: One often overlooked cause of a car surging with the AC on is actually a worn compressor belt. If the belt is stretched or worn smooth, it can slip during operation. This places significant strain on the engine and the AC system. Replacing the belt often eliminates the surge, and ensures better AC operation.

What happens when your AC is low on Freon?
A low Freon charge can lead to compressor damage and overall inefficiencies of the air conditioning unit. This problem happens when the low refrigerant causes freezing on the evaporator coils. Eventually, the ice build-up leads to the insulation of the coils and slows the cooling process.
What happens when a fuse blows in a car?
Usually, a blown fuse just causes a minor car electrical problem, like backup lights or interior lights not working, not being able to use your radio, losing a turn signal, or some of your climate control features not functioning properly. In rare cases, though, a blown fuse can mean that your car won’t start.
How do you clean condenser coils?
Check your air conditioner warranty before cleaning.

How much does it cost to recharge car AC?
How much does it cost to recharge the air conditioning in your car? On average, it can cost you anywhere between $150 to $300 if you get it changed professionally. However, if you choose the DIY route, the car AC recharge kit will cost you $40 to 50.
Your car is blowing warm or hot air instead of cold.
Your car is visibly leaking refrigerant.
The A/C clutch is not engaging.
There’s a weird smell coming from your vents.
How do I know if my car AC needs Freon?
One of the most obvious symptoms of low Freon levels is if your air conditioner is blowing warm or room temperature air. As we discussed, the air conditioning system in your vehicle operates by circulating this pressurized refrigerant. When the amount drops too low, it eventually affects performance.
How often should you recharge your car AC?
How often should you recharge your air-con? Most vehicle manufacturers recommend that you service or regas your car’s air conditioning system every 1-2 years.
Can a car lose refrigerant without a leak?
Some loss of refrigerant is normal over time, even without a leak, but it shouldn’t affect the functioning of your AC system.
How do you know if your AC is low on Freon?
Five Signs your AC is Low on Freon
It takes much longer than it should to cool off your home.
Your utility bills are higher than usual.
The air coming out of your vents isn’t cold.
Ice has started to build up on your refrigerant line.
You hear loud or unusual noises coming from your unit.
How long should a car AC last?
What’s The Usual Number of Years? It has been estimated that an A/C compressor can last from eight to ten years. Many drivers will then say that they will not need to change their A/C compressor at all since this number denotes the life of the car.
Here are some signs that your AC compressor is about to fail – or has failed already.
AC not as cold as it should be.
Noises coming from the engine compartment.
Damage evident on the AC compressor.

Can you drive with bad AC compressor?
It’s not a good idea to drive with a broken A/C compressor. While you can sometimes drive your vehicle with a broken A/C compressor without needing expensive repairs, it’s not wise. When these integral parts of your car’s air conditioning system break, that can cause greater damage to your engine and even your health.
What kills an AC compressor?
Loss of refrigerant: This is the #1 way a compressor might die years before its time. The amount of refrigerant in an air conditioner is specially set to work with the compressor. If the AC loses refrigerant through leaks, the imbalance will eventually cause the compressor to overheat.
