On the other side, a poor working AC may just make your trip challenging with unimaginable pain that you can’t describe. Due to sweaty body or palms with sweat dripping down, it is hard to even comprehend the actual state. Hence, air conditioners are a necessity that act as an important mechanism to give respite from humidity and prickling heat. However, ACs may dysfunction on any specific day as they are also prone to breakdown.

This is where the following post guides and enlightens you about car compressor AC systems:-

The Compressor is the heart of your AC


The Car compressor AC systems comprise an electrical as well as mechanical formation. The air-conditioning unit comprises three parts namely a compressor, a condenser, and an evaporator. The compressor AC is an important, delicate, and highly complex component. It works by giving due pressure to the AC system while ensuring a flowing refrigerant for optimum functioning. Considering the constant on and off cycle, it is more likely to develop snag and hence undergoes proper introspection, and if needed has to be replaced as well. If the compressor fails, the ac can’t run properly too.

No cool air

It can’t be more depressing than to find warm air making its way inside, from your ac. The problem is the result of a refrigerant leak as the components of ac depend on refrigerant for cooling the vehicle. A leak may happen due to a hole in the compressor, condenser, hoses or due to an evaporator that gets ruptured. Contact an automotive technician who will rely on tools to identify the leak and likewise repair and recharge for blowing cool air again.

Go Low

Set the air conditioner to the lowest temperature to enhance its efficiency. Since, it will dry out less air, while directly benefitting you in terms of saving fuel. After all, the AC system is engineered in a manner where the air is cooled to 38 degrees. Now, if you allocate a higher temperature, you indirectly force the system to heat the cool air, as it is going to consume more fuel in the process.

Never pre-cool your car


Your car’s air conditioner operates at the best efficiency while driving. Hence, never make the mistake of pre-cooling your vehicle from before. In order to instantly remove hot air, the moment you sit, you can run the fan in the highest mode and open back windows for a few seconds to force the hot air out.

You ac remains inoperative while Switching it ON

You tried to turn it ON, but the blower throws warm air only. It may be because of the compressor clutch that fails to operate. The clutch is responsible for activating the compressor ac but if it breaks, then it signifies that it can’t receive engine power to generate cool air.

Ensure that the filter is neat and clean

If you have ever experienced reduced air flow, then you should get the cabin air filter checked. In all likelihood, there may be dirt and the filter needs to be changed. If you are confident to replace on your own, then you can save a certain amount. Usually, in current cars that have air conditioners designed in a manner, where the filter is easily accessible behind the glove compartment

AC is too noisy while turning ON


A car that starts to make noise is a sign of impending trouble and the same goes for the air conditioner. Since it generally runs quietly but you are in trouble if that happens. There are a series of apprehensions that comprise the banging or rattling sound due to the possibility of leaves or dust/dirt blocking the unit. Get the component examined by an authorized agent immediately who will enlighten you about the cause and if needed will replace the component(s).

AC soon emits warm air after cooling for sometime

Quite a common complaint that people even try to vent their anger on social media problems or during lunch hour at the office where the air conditioner fails to provide cool air after some time. Even the air conditioner repair centers acknowledge it being a common concern. It may happen due to a clogged expansion valve that blocks the refrigerant from further pushing air into the evaporator. Get it repaired by an authorized technician so as to prevent its repetition.

Water on Floorboards

When constantly using the air conditioner, it’s natural that you tend to get moldy smell. Well, it is due to bacteria building up on the coil of the evaporator. Over time, it creates a slimy film that even clogs the drain line. The excess moisture fails to move out. So, if you find the floor of the vehicle slightly wet, then get it examined at the automotive center for instant introspection.

Frequently Asked Questions


Why Burning smell is coming out from the AC?

If there is a burning smell from any electrical appliance in your house or in your car air conditioner, then be alert. It may be because the wiring of the compressor is either overheated or burnt. A damaged compressor fails to properly function while posing even a greater threat to electrical burns if not timely checked.

What is the speed of car AC compressor?

Usually, it depends on the speed of the car engine, but it is somewhere between 800 to 3,000rp

What is the unit of the compressor?

The compressor is measured in ‘horsepower’ popularly denoted as HP as well as ‘cubic feet per minute of intake air’, in short CFM.


Considering the complex nature of the Car compressor AC system, they need timely service and regular upkeep failure to which they may report warm air, noise or moldy smell, moisture leaks, or improper air conditioning. They need introspection from experts who can advise and rectify the problems for you to take on the normal functioning of your day-to-day affairs.
