Here is Why Car AC NOT Blowing Cold Air After Recharge

It’s a nightmare to find your car AC not blowing cool air in burning summers. But, people generally face this issue. Therefore, even if you have recharged the AC of your vehicle, the issue in other car machinery can affect its working too. So, let’s find out why the car AC not blowing cold air after recharge.

Why Is Your Car AC Not Blowing Cold Air After Recharge?

There could be numerous reasons for the improper AC working after you recharge it. You can handle the situation by finding out the most common reasons for this right away!

1. The Compressor is Unable to Connect

Numerous reasons can cause the compressor to not connect with the vehicle AC. It could be an electrical failure in the circuit during charging, overheating the vehicle, or maybe the car AC coolant is just low. 

Today’s latest technology is capable enough to sense any sort of problem in the car. And, when it senses any issue, AC is the first thing to get shut off.  So, make sure that you check the compressor as it could be the reason why the car AC not blowing cold air after recharge.

2. Stuck & Blend Air Door

The blend air door is the reason for drawing hot air to cold air in your car system. This door is located in the ventilation system. The hot air is blown directly from the engine if the blend door isn’t working properly. 

Therefore, you need to take your car to the mechanic whenever you find any fault in the stuck blend door.

3. Leaking Coolant

The latest technology car system is more sensitive than the older ones. The chemical Freon or simply what you can call coolant is the reason why the AC cools hot air quickly. The chemical can run out if there is any leakage in the AC. 

Thus, AC would not work, as there is no Freon in the system. You can handle this situation by using the best maintenance tips

Use a charging machine that will pour coolant and make your AC work properly. If the AC still doesn’t work even after using the charging machine, contact the nearest mechanic.

4. Dirty System

Another reason why the car ac recharged but not cold enough is the ac system is filled with dirt and debris over time.

The evaporator is prone to collecting a lot of dirty things that can lead to tons of issues, including misblown AC. This is why, at the very least, the entire system should be flushed and cleaned once a year. 

Cleaning the A/C is more than merely spraying compressed air into the vents. You must take the car to a professional shop for service. Typically, the technique will entail removing the evaporator from behind the dashboard and cleaning the operable parts. 

The specialists will also inspect the expansion valve, the quantity of oil and refrigerant in the system, and, if necessary, adjust the thermostat.

If you don’t diagnose any of the above issues, the chances are that your car must be having some other problem. The improper or no working AC can signify some serious problems. 

Though you can handle serious issues as well with some DIY solutions, it’s preferable to let a mechanic take care of the internal machinery.

Car AC Not Blowing Cold Air After Recharge: How To Fix (In Detail)

Below are some acts you should perform in detail when your car AC not blowing cold air after recharge.

Examine the refrigerant level. This liquid circulates throughout the AC system. When subjected to high pressure, this liquid condenses into a liquid, but when exposed to low pressure, it evaporates.

Because your car’s air conditioning system is closed, leakage inside the system might result in refrigerant loss. If you have a continual low refrigerant level in your AC system and heated air instead of cold air after recharging, look for and repair any leaks.

Even if your vehicle’s compressor is brand new, consider replacing it. While it is not always obvious that the compressor is the problem, replace it after a competent technician determines that it is the compressor that is impacting the AC’s effectiveness.

Assume our car’s compressor often fails; it is preferable to get it changed rather than cope with the consequences. The compressor replacement might cost between $500 and $800, which includes labor.

A recently replaced and nonfunctional compressor at an authorized repair shop is also promptly replaced and retested.

How Much Does It Cost To Fix Car AC Not Blowing Cold Air After Recharge?

The cost of diagnosing and repairing a car air conditioner that isn’t blowing cold air varies according to the complexity and severity of the problem.

The brand and model of your vehicle will also influence the cost, as more complicated cars need more modern diagnostic equipment and experienced personnel. Before having your car’s A/C system tested, we recommend receiving a price from a reliable repair or auto shop.

The following are the typical expenses for popular A/C automobile repair services:

  • A/C Repair – $350 to $450
  • A/C Recharge – $230 to $290 
  • Compressor Replacement – $1,550 to $1,700

FAQs on Car AC Not Blowing Cold Air After Recharge

1. How long does it take for AC to get cold after recharge?

It doesn’t take so long after recharging for the car air conditioner to blow cold air as normal. Car overall systems are different from one to another, so you can not expect an exact period for all. But the typical recooling time of car AC air is from 2 to 2.5 hours.

In case you have a mobile AC, it will take you an additional 15 to 30 minutes for the cold air to be released. After that period, you can right away feel the cold air blowing through the AC vent. 

The settling down time allows the whole car AC to function properly and distributes the coolant throughout to ensure the smoothest cooling process. 

2. Does over-recharging AC cause it to blow hot air inside?

If your car’s air conditioning system is overcharged, which might harm your compressor system, you should address the matter as quickly as possible.

Overcharging your car’s air conditioning system results in an excess of refrigerant. Excessive refrigerant can result in high pressure and heat, resulting in hot air blowing out of the system.

Furthermore, as extra refrigerant builds inside the compressor, it might cause sub-cooling. Furthermore, flooding the compressor’s mechanical components might cause harm. As a result of several sections of the system failing, overcharging the AC will cause it to spew hot air inside.

3. Why is your car blowing hot air?

A refrigerant leak is frequently the cause of a car A/C spewing hot air. Refrigerant is a liquid that runs through the A/C system of your vehicle, expanding and contracting as it eliminates heat and humidity from the cabin.

Without adequate refrigerant levels, none of the other A/C components will operate properly.

4. What are the symptoms that car ac needs a recharge?

If your car AC needs a recharge, you may notice the following signs:

  • Car blowing warm or hot air through vent instead of cold air
  • Easy-to-spot coolant leaking 
  • Smell comes from car AC vent 
  • Unengaged AC compressor clutch

5. How often does a car AC need to be recharged?

The air conditioning in your automobile should be replenished every two years or so. However, if you detect any indicators that your air conditioner needs to be recharged, you should take your car in as soon as possible. 

Taking care of your car’s air conditioning system is critical for various reasons.

Conclusion

So, whenever your car AC not blowing cold air after recharge, follow the above tips. Or, you can simply take your vehicle to the professionals as they know what exactly to do. Moreover, a timely repair can avoid future issues as well.
