7 Reasons Why Your Car AC Not Blowing Cold Air

It’s not at all fun being stuck in your car without air conditioning on a hot summer day, particularly in a vehicle where temperatures can rapidly reach 150 degrees.

In any case, A/C is far more than just a sign of luxury and comfortability; it’s a security issue as well. One of the riskiest spots for somebody to be during a hotness wave is within their vehicle without A/C since temperatures can spike to hazardous levels pretty quick.

So in such a case, if your car’s air conditioner is blowing hot air, here are some common reasons you must check immediately to sort the issue out:

Refrigerant Leak

Why is your car’s air conditioner not blowing cold air? Blowing hot air is frequently the aftereffect of a leakage in the refrigerant gas. Refrigerant is a fluid that flows through your air conditioner’s A/C framework, extending and contracting as it eliminates hot air and dampness from the lodge.

None of the other air conditioner’s parts will work effectively without appropriate refrigerant levels. However, any leak due to an old hose is just like a rusted or penetrated evaporator.

Be that as it may, don’t hope to recognize a refrigerant hole effortlessly. You presumably will not see a puddle of fluid in or under your air conditioner. That is because dissimilar to the engine oil and other indispensable air conditioner liquids, radiator fluid vanishes when presented to the environment. Once in a while, you’ll luck out and notice a greasy buildup at the specific area of the hole.

It is crucial to detect a refrigerant leak, and you can do so by visiting any car garage of mechanic professionals to infuse dye into the system to detect it. When they recognize the wellspring of the hole, they fix and re-energize your car’s air conditioner so it can blow new, chilly air.

Clogged or Broken Condenser

The condenser is the piece of the AC unit that is answerable for transmitting or dispersing the heat from the air and the fluid refrigerant coming from the compressor.

It permits the liquid refrigerant to chill off a little to get back to its original state again and flows back through the unit. However, when this process fails, that is the point where your car’s air conditioner start blowing hot air.

Or, if some flotsam hinders your cooling condenser and jetsam driving out and about, it will not have the option to cool the refrigerant appropriately, and your Car will keep on working with overheated coolant. It will prompt the A/C unit to blow hot air.

When the ventilation openings on the condenser are hindered by the gathering of dirt or road debris, air will not stream uninhibitedly over the copper coil, in this manner driving the part to hold a portion of the warmth, and the outcome is powerless cooling or hot air.

On the off chance that the condenser doesn’t look impeded or obstructed on the investigation, you must check the condition of copper pipes. Assuming there’s any hole on the line that seems compacted, it very well may be obstructing the free-progression of refrigerant through the unit. This may result from a street shot crashing into the line or a mishap that caused a knock on your bumper or guard.

Broken or Faulty Cooling Fans

A common question always arises in everyone’s mind; how to make AC colder in car?. Therefore, your car’s air condition condenser accompanies a couple of cooling fans that assist in disseminating heat from the refrigerant.

Consequently, if your cooling fans are broken, they cannot eliminate heat adequately from the refrigerant. While the air you get from a messed-up fan won’t be just about as hot as a faulty condenser, it is sufficient to make you sweat inside the car.

Additionally, your cooling fan’s sharp edges are not intended to be solid, and they can break whenever hit with garbage driving not too far off. If the cooling is broken, the replacement is the only option that could work well.

Clogged or Dirty Cabin Air Filter

Not every car’s cabin needs to be furnished with an air conditioner. However, the main aim of the air filters is to stop the dust particles or any other dirt from entering the cabin via air. Those that do have them need a perfect, unhampered surface to permit air to travel through openly.

Lodge air filters can catch dust, bugs, leaves, and other different kinds of flotsam and jetsam. And here you must have noticed that the car AC is suddenly blowing hot air. A messy air channel can surely hinder your climate control system’s capacity to cool and, after time, could cause pointless strain on the whole framework.

Bad or Broken Compressor

The compressor is the core of the air conditioning system, and its responsibility is to keep the refrigerant traveling through the unit consistently. On the off chance that this part isn’t working accurately, the radiator fluid will not have the option to arrive at the condenser for cooling.

Compressor issues usually come occasionally when ac is not being used, for example, long winters when A/C isn’t required. Be that as it may, to keep this from occurring, numerous more up-to-date vehicles keep the condenser dynamic all year by enacting it under the thaw-out setting.

So, it is also recommended to keep running AC on the max throttle for 10-15 minutes each half a month, independent of the external temperature.

Car’s Electrical System Problems

If all the parts of an air conditioning unit are working fine, your car might be blowing hot air due to an electrical issue. A broken wire or a blown breaker can forestall a generally solid A/C from working. Diagnosing and amending an electrical issue starts with carrying out a total visual review of your car’s wire box and wiring.

While this arrangement and defensive provisions assist with keeping perilous fires from filling in the electrical framework, it likewise implies that something as straightforward as possible reasons your car AC to quit working.

You’ll have to investigate every one of the wires entering and leaving the AC to check whether any wires are broken or frayed. Likewise, you ought to follow them right to the circuit box to check whether there’s a messed-up intertwine.

Assuming notifying any wire that looks broken or melted, you’ll need to supplant them and potentially change a circuit. It is recommended to use the appropriate test instruments and the vital experience to analyze such issues.

Bad AC Compressor Clutch

There is a good possibility that the AC compressor clutch will remain stable for a long time to come without wearing out on you when you initially get your car. However, on the off chance that it at any point gives out on you and flop totally, it won’t be tough for you to tell.

It would help if you spotted no less than a couple of signs showing inconvenience in a little while. And this could be another reason your car air conditioner is not blowing cold air.
