When it comes to bringing comfort in your car journeys, car ACs play a crucial role that sometimes we don’t even realise. Whether you are going for a short ride or a long drive, if the car’s AC is not working properly, you won’t be able to enjoy your journey. So, if you are struggling with issues like car AC not cooling, you need to call the car AC professional repair. They will help in diagnosing car AC issues and repair your car AC. Also, if your car AC blows hot air and you wonder why is my car AC blowing warm air? It’s time to call for professional repair. This blog will discuss some common car AC problems and why early detection matters. So, let’s begin!
Check These Pointers if Your Car AC is not Cooling
1. Low Refrigerant Level (Gas Leak or Depletion)
The first and most common reason your car AC is not cooling at idle is low refrigerant levels. This primarily happens when car AC leaks gas or a depletion occurs. With time wear and tear happens, and small leaks can get larger in size if not repaired timely. Also, natural evaporation can contribute to lower refrigerant levels. As a result, your car AC keeps blowing hot air. So, if you are witnessing such issues, it would be wise to call for professional help.
2. Clogged Cabin Air Filter
Another essential reason that your car AC is not cooling is the clogged cabin air filter. If you are not following regular maintenance for your car AC, you might end up with a clogged cabin air filter. Over time dust and dirt begin to accumulate over the cabin air filter. This can lead to clogging which interrupts your car’s AC’s cooling capacity. Therefore, if you don’t want to waste money on frequent replacement of the cabin air filter, it would be helpful to follow these car AC maintenance tips.
3. Faulty Compressor or Compressor Clutch
A faulty compressor or compressor clutch is another essential factor that contributes to the car AC not-cooling hazards. When your car’s AC compressor fails, it leads to inefficiency in circulating the refrigerant air throughout the car. Inefficiency in circulating refrigerant air leads to poor AC function and not cooling air inside the car.
4. AC Condenser Blocked or Damaged
Another key reason why your car AC is not cooling properly can be blocked with dirt, road pollutants or a damaged condenser. When your car AC condenser is blocked or gets damaged due to wear and tear, it loses its efficiency in cooling the air. As a result, your car AC fails to cool down the air inside the car.
5. Electrical Issues or Blown Fuses
Electrical issues or blown fuses can also cause your car AC to blow hot air. The underlying wiring problems, faulty relays or blown fuses can interfere with your car AC’s capacity to cool down the air. Early detection and repair can significantly save Car air conditioning repair costs in the future.
6. Cooling Fan Not Working Properly
If your car’s AC is not cooling as it should be, it can happen due to a malfunctioning cooling fan of the AC. A broken radiator fan can reduce heat exchange and impact AC cooling capabilities.
7. AC Evaporator Issues
Not to mention, natural evaporation can often cause obstacles in your normal AC functioning. Also, leaky or frozen evaporator coils can cause weak or no cooling inside the cabin which results in no to low cooling.
8. Thermostat or Temperature Sensor Malfunction
A malfunctioning thermostat or temperature sensor can cause problems in your car AC’s cooling capabilities. Usually, incorrect cabin temperature readings can lead to poor AC regulation and the inability to cool down the cabin air.
9. Internal AC System Leak Detection Failure
Sometimes the internal AC system leak detection system fails to detect tiny leaks in hoses, seals, or O-rings. These nearly invisible leaks are hard to detect but kill the cooling power of your car AC and lead to no or poor cooling.
10. Improper AC Maintenance or Delayed Servicing
Lastly, improper car AC maintenance or delayed AC servicing can lead to poor or reduced performance of your car AC. Therefore, skipping regular car AC servicing in summer can cause poor to no cooling inside the car.
FAQs
Why is my car AC blowing hot air instead of cold?
A leakage in the refrigerant often causes car AC to blow hot air instead of cold.
How can I tell if my car's AC is low on refrigerant?
One can identify a low refrigerant in car AC if the car AC is blowing warm or hot air.
Is it safe to drive with a faulty AC compressor?
If there are car AC compressor problems, it can result in a noisy compressor. Driving with this issue is not problematic in the short term. However, with time, the problem can become severe and costly to repair.
How often should a car AC system be serviced?
Car AC system servicing should be done at least once a year.
What are the signs of a blocked or damaged AC condenser?
One of the most common car AC problems is a damaged or blocked AC condenser. This problem can be identified by loud noise in the condenser, AC not working and high energy bills.
Can a clogged cabin air filter reduce AC cooling?
A dirty or clogged cabin air filter can reduce AC cooling. And one may find their car AC not cold enough.
How much does it cost to fix a car AC that’s not cooling?
Car AC professional repair can vary depending on the agency you choose. Select a repair shop that offers cost-effective repair solutions.
Can electrical issues stop the car AC from working?
The function of your car AC depends on electrical factors such as connection, wires and fuses. A faulty connection can affect the effectiveness of your car's AC.
Why does my AC cool only when driving, not while idling?
Car AC not cooling at idle and only working when driving can be a result of a faulty compressor. Regular professional maintenance of car AC can help you avoid such issues.
Should I refill the AC refrigerant myself or go to a mechanic?
Refilling car AC refrigerant is not an easy task; one can overfill or make other errors. Hiring a professional mechanic is the best option for refilling car AC refrigerant.
