Top 10 Reasons that your Car AC isn’t Cooling Enough

You are all set for a road trip in the summer weekend; but all of a sudden you realise that your car AC is not working properly in the midst of the highway. Or is the car AC not cooling enough? What’s next?

Surely you can’t afford to get boiled in the heat! The temperature outside is closer to 100 degrees and the heated-up engine goes on blowing heated air inside your vehicle. Moreover, finding a service centre or a mechanic in the midst of almost nowhere is difficult.

Believe me, nothing can be a spoiler than this, for ruining the weekend trip that you’ve been planning for a long time! That’s one of the reasons for which you need to know the factors that can be the probable culprits for affecting your car AC. let’s take a deep insight through some of those, here are 10 reasons that your car AC isn’t cooling enough:

1. Is car AC cooling low? Mould and Mildew Build-up
   

   

   When we tend to keep the car AC On for a long time, small microorganisms can block the AC vents. These bacteria can block the AC vent and affect the cooling procedure. When this happens, no matter how much you try, the vents don’t work properly. It’s one of the reasons for which your car AC is not cooling the cabin properly.

   To avoid one such threat, it’s better to take the car for servicing at least after 5-6 months. A periodic service not only clears the AC duct, but it also evades common dust particles and other microorganisms like bacteria and moulds to grow and propagate on a rapid scale.

   It’s not only a hygienic remedy but also a smart way to maintain the durability of your car Air Conditioner thereby adding longer life span to your car air cooler.

2. Is car AC cooling low? Electric Issues might be the reason
   

   An unwanted short circuit in the electrical unit is another unexpected reason for which your car AC may stop working.

   It’s a common thing in maximum vehicles these days. If you’re living in a climate where the outside temperature tends to go above and beyond 45 degrees, the electrical wires might get hot enough and cause a short circuit in the internal wiring.

   There’s a smart DIY repair work to evade such inconvenience. Analyze the area where the wire has been shot, seal it with an electricity resistant tape and join the other end with the connecting wire. However, you can also take the car to an authorized car repairing workshop to get that done. If your car insurance covers the same then its tie for you to sit back and relax and let the experts do there job.

   At times, it might not be possible for you to diagnose the problem, and if you misplace or dislocate the wire while running a DIY repair work, you may cause more harm to the electrical circuit installed inside. You may have to flood a bulk amount of dollars to meet the repair expenses.

   It’s better if you avoid doing it yourself, as you don’t know how to handle the technical problem and which is the root cause for one such trouble. So consider hiring an authorized car mechanic to repair it before setting out for a long drive.

4. Is car AC cooling low? Condenser Blocked/Broken

   A broken condenser is another genuine cause for which your car AC may not work properly. It’s that particular unit in your car that keeps the refrigerant cool and then flows through the blower by converting the hot air into cool air.

   That air blows through the AC vents which you breathe inside the car. It’s located in front of the grille. If there’s any trouble in it, you can locate the grille and diagnose it easily. If there’s a blockage and there’s some debris or dust found in it the issue may overheat the car. The heated air that constantly blows through the vent inside your vehicle, may damage the condenser if it’s not taken care seriously.

If everything sounds good, the air cooler is working perfectly fine. If not, the blower will not spin at the required speed and you’re going to feel it on your hand palm. That’s when you need a mechanic to fix a technical issue like this up.

   The compressor needs a lot of power and energy to work fully functioning. If the compressor gets weak or worn out by constant usage then there is a noticeable lack of energy in compressor which leads to AC malfunctioning. Week Compressor belts prevent your car from starting it up. Those compressor belts usually drive the power and energy functioning in your vehicle.
