Car’s Air Conditioner

Why Your Car’s Air Conditioner Isn’t Cooling Properly – Common Causes Explained

You are driving in the scorching UAE sun and you are about to switch to the sweet cold air rush when your car air conditioner blows hot air. There is nothing more exasperating than a faulty AC in a place where the climate usually gets above 45°C.

When you think your car is getting hot, then you need not worry (literally). It is time to explore the most frequent causes of your car AC cooling problem, and how car AC repair and intelligent car AC maintenance tips will help you restore the coolness of your drives.

Low Refrigerant Levels

Low refrigerant is one of the most common reasons for weak cooling. The refrigerant or gas is the blood to your car air conditioner system, it is the one that absorbs the heat and changes it into cool air.

Leaks may come about as a result of worn out seals, broken hoses or broken connections. When your AC is blowing slightly cool or it takes too long to cool, you need to make sure a technician inspected refrigerant pressure and restored it in case it is low.

Hack: It is always advisable to have the refrigerant replenished by a professional car AC repair agent or centre to whom you present the appropriate gas that fits in your car model.

Clogged Cabin Air Filter

The cabin air filter makes sure that the air in your car is clean and free of dust. Nevertheless, in the dusty areas such as Dubai and Sharjah, it becomes clogged easily.

When it does, the amount of airflow decreases, and your car air conditioner should be overworked, which means low cooling efficiency and increased energy use.

Pro Tip: To keep the air quality and cooling performance at an optimum, change or wash your cabin filter on an average 10,000-15,000 km to ensure both are kept at their best.

Faulty Compressor

The compressor is the core of your AC system that circulates the refrigerant within the system. A bad compressor would imply lack of pressure, lack of circulation and consequently, lack of cooling.

You may hear odd sounds, clicking sound, or no cooling whatsoever. Professional car AC repair service is often necessary in this problem as compressors are complicated and expensive parts.

Pro Tip: Use your AC a couple of minutes each week even in the winter. This is used to keep the compressor lubricated and prevents unexpected breakdowns.

Condenser Issues

The refrigerant gas is compressed then cooled in the condenser. When it is covered by litter at the road, or bugs, or leaves, the heat does not get dissipated, and warm air tends to be blown in through your vents.

In some cases, the leaks or blockages may also be caused by the physical damage of the condenser (by stones or small accidents).

Tip: Every now and then, see how far your radiator grille sticks out at the front and remove any obstructions you can see and wipe them off to allow adequate airflow.

Sensors/Electrical Failures

The car air conditioner system also has several sensors and electrical elements that assist the modern car in functioning effectively. Even a broken fuse or a loose wire or a faulty temperature sensor can discontinue the whole cooling process.

When you are having problems with your AC which includes the AC turning on and off erratically or the AC not turning on at all, then it may not be a mechanical issue but rather an electrical issue.

Pro Tip: Do not undertake home electrical repairs. It is better to ensure that your system is serviced at an approved car AC repair shop in order to eliminate subsequent problems.

Evaporator Coil Problems

The evaporator coil will absorb the heat in the air in your car. Dust, or moisture, or even mold, may accumulate upon its surface over time, and thus lower its efficiency in cooling air.

The vents have a musty odour or the poor flow of air is also a common indicator of a dirty or clogged evaporator coil.

Pro Tip: Clean your evaporator on a regular basis as a car AC service to prevent long-term cooling problems.

Poor Maintenance Habits

The maintenance tips of the car AC are not only good to know, but they are also necessary in the harsh weather in the UAE. Failure to maintain your AC system may cost you a fortune and embarrassing rides.

The following are some of the smart habits that should be sustained to perform optimally:

• Use your AC at least 1 time a week even in cooler seasons.

• Have your AC system checked after every 6-months.

• Small inconveniences such as a sluggish airflow or a poor cooling effect should not be overlooked as they are the precursors of bigger problems.

Final Thoughts

A car air conditioning is not just a comfort factor, but it is a requirement to safe and enjoyable driving in the UAE. It can be a leak of a refrigerant in the car air conditioner or a plugged filter but regardless, it is no fun to deal with at the end of the day when it comes to time, money, and inconvenience.

When you are looking to have a car ac repair or car maintenance, then make sure that you go to a reliable car service centre that focuses on car maintenance and is aware of the peculiarities of UAE roads and climate. Be safe and make your next drive as refreshing as it can be.
