6 Reasons Why Your Car Air Conditioner Is Blowing Hot Air
Winter ended and summer just began, meaning it’s time for your car to get ready for the outside heat by rolling up the windows and turning on the air conditioner. But what if Your Car Air Conditioner Is Blowing Hot Air?
If that’s the case, and you wonder why the car ac is blowing hot air? Then you are at the right place as in this article we will take a look at the 7 reasons why your car’s air conditioner is blowing hot air.
In most cases, your car’s air conditioner may blow hot air due to low refrigerant, a blocked or faulty condenser, broken cooling fans, or some other cause. Check out this article to find out more.
So let’s get into it-
If there is a problem with your car’s air conditioning system, it implies that the parts are not functioning properly and hence the ac is not performing as it should.
That’s why you need to inspect your car’s air conditioning system and correct it if it needs some tweaks.
Take a look at the reasons for this issue.
Among the reasons that cause your vehicle’s air conditioner to blow hot air is a dirty air filter. If you are not maintaining it regularly, then chances are that the filter has collected a lot of dirt and debris which affects the cooling process of your car’s AC system.
If you are smelling musty smells from your car ac or if it’s noisier than before then this usually means the air filter is dirty and you need to repair it. You can either replace them yourself or could take some help from a trusted car repair shop. This is one of the most common Reasons Why Your Car Air Conditioner Is Blowing Hot Air.
Low refrigerant or coolant due to a leak is another reason why your car’s AC is blowing hot air. This issue could be troublesome as you first need to fix the leak before topping up the coolant again.
The primary purpose of refrigerant is it expands and contracts as it removes heat and humidity from the interior. The other A/C parts won’t function correctly without the correct refrigerant levels.
If your AC starts blowing warm air it usually indicates you need to refill your refrigerant immediately as soon as you notice warm air inside your car that is coming from the ac.
If you believe this to be the case, you should seek immediate repair from a reputable mechanic to prevent additional harm.
If there is a problem with your vehicle’s condenser, then that could also cause your car’s AC to blow hot air.
Let’s understand how a faulty condenser can affect AC systems –
The condenser basically is responsible for removing the heat from the refrigerant. As the condenser takes the heat from the coolant to discharge it outward, if it malfunctions the whole process of cooling would suffer resulting in car ac blowing hot air.
Usually, the dirt and debris in the condenser can sometimes block it which prevents cool air from entering the grate that assists in cooling. In such cases, the compressor will not be able to cool the refrigerant. Faulty Condenser is the most common Reasons Why Your Car Air Conditioner Is Blowing Hot Air.
The compressor being one of the most crucial components in your car ac system is responsible for circulating the refrigerant in the first place. If it fails, it can cause your car ac to blow out warm air and you have to go for car ac servicing.
In order for the Compressor to perform well, it needs to be used frequently, so if it isn’t used or has been inactive for a long time, the Compressor can fail to work from the shock.
Hence in order to keep your ac compressor in good shape, you should keep the ac on at least for 15-20 minutes every week especially in winters as most people usually don’t do it.
The other reason why your car’s AC could be blowing warm air is because of some problem with the electrical system.
As all the components in the car ac system depend upon the electrical system, any issue in it be it in the fuses, switches etc, can cause the ac to malfunction.
The problem mostly occurs when there is frayed or faulty wiring that creates a snowball effect causing the air conditioner to blow hot air.
If you’re wondering why your car ac is blowing hot air, don’t forget to check its cooling fans too.
The cooling fans inside the condenser work to reduce the heat from the refrigerant. If these are broken or faulty you can forget about any cooling whatsoever. It is one of the most common Reasons Why Your Car Air Conditioner Is Blowing Hot Air.
If they’re not functioning in the right way, then it could be an issue with the air conditioning unit’s ability to provide cool air. In such cases, you will have warm or hot air entering your car’s cabin instead of cool.
Moreover, the blades should be able to move freely, so make sure no leaves or insects are wedged between them.
