In the scorching heat of summer, life seems impossible without AC. In fact, an air-conditioned car is a must for a long drive these days. Another such case, it can be very irritating when car AC not blowing cold air when idle or not work at all, although it is a common problem. When your car crosses the bench-mark of 100,000 miles travel, problems are bound to arise. But have you ever wondered why is your car ac not cold enough or car AC not blowing cool air when idle? In this article, I have explained deeply about the issue and its solutions.
Why Does My AC Gets Warm At Idle Condition?
There can be multiple reasons for this mishap happening. Basically, your AC does not stops working at all, mostly it just performs below average. Even the finest ones will not work with full efficiency when idle due to the fact that the engine is running slower and thus less coolant is being compressed. The effective cooling of AC is inversely proportional to the outside temperature increase. Below are some of the most prominent reasons behind your car air conditioner blowing warm air:
1. Poor Maintenance
Probably the most common and the most ignored one is lack of proper maintenance and hygiene over a period of time. According to experts, it is a slow killer which can damage your system to beyond repair if left untreated at some point of life( scary, isn’t it?)
2. A Defective Condenser Fan
The first thing you should look for after spotting this issue is checking whether the condenser fan is working properly or not. In case it is damaged, it cannot perform with full strength and power. Make sure the fan is properly connected and fitted properly in the slot.
3. Engine Overheating
An overheated engine is another common reason for blowing not so cool air in idle conditions. If the internals is heated then no matter how good your car Ac is, it is bound to malfunction.
4. Loose fittings
It is common to observe loose ends of various parts in suspension after a few thousand miles of travel. Depending from road to road and model to model, damage may intensify or lighten.
5. Foreign Debris
If you live in a polluted area, finding unwanted debris in most unwanted places must be more than a common issue for you! So make sure to clean your vehicle from time to time., or you may have to regret it later.
6. Out of Coolant
The coolant is the most necessary part of your car AC. When you run out of it, you may observe your car air conditioner blowing warm air.
Fix Car AC Not Blowing Cold Air When Idle
After a long list of problems, let us now head to the solution for car AC not cooling when idle. Although reasons can be many but the solution can be very common mostly, and in some cases, very particular. So let us talk about them elaborately one by one below:
1. Check For Poor Connections
Physically inspect each and every nook and corner of your system for any loose or displaced connections. If any found, repair it using proper kit recently. You may opt for professional help, but that may not suit the budget.
2. Refill Coolants
Make a habit of refilling coolant every 5000 miles travelled or depending on your rate of air conditioning. It will not only serve you with great cooling but also increase your AC’s lifespan.
3. Regular Maintenance
And the winner of the ‘BEST SOLUTION CONTEST OF THE YEAR’ is maintaining it regularly! I am not exaggerating. The secret behind amazing performance lies in how much you stick to your system’s maintenance plan.
4. Replacing old parts
Probably the most ignored one and the most important one too. Most people find it nonsense to replace the worn parts of the vehicle. But what they do not realise is that this habit can cost them exponentially if not repaired on time. Moreover, even a single fault can damage other parts in no time too.
5. Check for Damaged Lids
The fluid leaked due to lack of lid will not only increase your expense on fuel and fluids, it will even seep into nearby parts and corrupt them. In some cases, if that inflammable fluid anyhow reaches near spark plugs, it can prove to be fatal. You need to avoid this at any cost.
6. Avoiding Extreme Temperature
As they say, “One should avoid going to extremes, and should always follow the middle part” Well, it applies here too. Do you know using AC at extreme temperatures can expose your car AC system to huge unwanted pressure? It will not only depilate the cooling but also reduce its life span drastically.
7. Prevent Overheating Of Vehicle
If you notice overheating or fumes coming from the front end of the engine, do not ignore it as in some cases it can even cost you yours and your dear one’s life. Slow down your car, park it to a corner, open the engine front and let it cool for a few seconds. After that diagnose the underlying issue and solve it as quickly as possible.
Although I have mentioned all the necessary steps to be taken for particular problems, the key is to prevent rather than cure. Keep your car AC temperature between 19-27 degrees Celcius and you shoould not have any problem about car ac not cold enough. Use high-quality fluids like grease, lubes, fuel, lubricant, etc for your vehicle. Avoid pocket-pinching habits. Give your car regular checkups. These two play an equally important role in well being of your dear car so do not ignore it.
