Why the Cooling Power of the AC is reduced in your Car?

Many people found that their AC is not working properly in their summer weekend road trips. They are getting panic when the AC is unable to produce necessary cooling in the midst of the highway. When the outside temperature is high, it heated-up the engine and blows the heated air inside the car.

Due to these reasons, you get boiled in the heat inside your car. But finding a mechanic for fixing the AC of the car in the midst of highway is always seems to be a difficult task. Several reasons are affecting the cooling power of AC. Here are a few of them.

Damaged AC blower

Inconvenient cooling of AC is indicating the damaged AC blower vent in the car. The lifespan of blower vents is 6 to 8 months, so it's always advisable to diagnose it within its specific lifespan. You can easily determine the damaged AC blower of your car by using your hand palms.

For diagnosing it, you can show your palms at the front of the AC vent to feel the airflow speed. If the cooler is working fine, then you will feel the cooling, otherwise consult with a mechanic for fixing the AC blower vents which are not spinning at its required speed.

Broken condenser

The condenser is working in the AC module for keeping the refrigerant cool and convent the hot air into cool air by flowing through the blower. When the AC is not working properly in your car, check the condenser as soon as possible. In an AC, the air blows through the AC vents which are installed in front of the grille.

If the vents are blockage due to the dust and debris, then it will overheat the car and damage the condenser. Neglecting the issues may put sufficient load of the AC engine and eventually affect the air cooler.

Mildew blockage

When you are running the AC of your car for longer, eventually you will notice that the small microorganisms like mildew and mold block the AC vents. Due to these blockages, the cooling procedure is affected poorly and the vents are not working properly.

So, it's always better to service the AC after 5 to 6 months for not only cleaning the AC duct but also prevent the dust particles and microorganisms from growth in it rapidly.

Refrigerant leakage

In the cooling system of the car, the refrigerant keeps the cabin cool. But the leakage of refrigerant is the biggest cause behind the reduction of cooling as well as malfunction the AC system.

The main cause behind the refrigerant leakage is the unexpected accidents in which the AC hose is leaking from the joints when the oil substances gather around it. As a result, the refrigerant is damaged poorly and needs immediate repair for fixing the leakage issues.

Broken AC actuator

Apart from the AC blower vents, the AC actuator also plays an important role in operating the AC efficiently. While running the AC system in the car, many times you will notice that the AC is blown at the maximum and tend to open the air flaps.

If you are neglecting the issues for a long time, then it will likely produce hot air from the outside and slowing down the cooling air produced inside the car. So, diagnose the AC actuator from an authorized car servicing workshop and perform the essential repairing of the AC system.

Electrical problems

Nowadays the electrical problem seems to be the common issue found in most of the cars. It is mostly found in the climate where the outside temperature is higher than normal which can heat the electrical wires and cause a short circuit in its internal wiring.

So, the sudden short circuit in the electrical unit of the car is the other cause behind the reduction of cooling in the AC system. If you are neglecting the issues, then it may have to spend a bulk amount of dollars for bearing the repair or replacement expenses.

Conclusion

When the AC system of your car is not used for a longer time, it will cause numerous problems while running. Make sure that you have properly checked the AC system of the car before you are set up to going for a weekend or holiday trip.
