Nowadays, air conditioning is a standard feature in most vehicles. Nevertheless, when people take their vehicles for a routine checkup or repair, they prioritize the engine and other vital aspects of the vehicle.  Most car owners often ignore developing issues on the air conditioner of their vehicle and they at times end up paying a huge amount of money to have the AC replaced or fixed.

Most of the things that make an AC stop functioning develop over time and it is therefore not possible to realize sudden issues. Nevertheless, if you are experiencing a more obvious issue like unexpected or loud noises coming from your vehicle’s AC, you should take it to a mechanic as soon as possible. Apart from loud noises, there are other issues to look out for. By learning about car air conditioning Alexandria residents can tell when to take their cars to a technician for AC repairs. Some of the common AC issues include:


The role of an air conditioner is to lower the temperature inside your vehicle. It also cools, cleans and dries the air by forcing out the warmer air inside. If the air conditioner is contaminated by moisture or debris, it will not cool the surroundings. It is important to hire an automotive technician to repair your AC if moisture is trapped in it.

Pungent odours 

Bacteria and fungi among other microorganisms may develop in the air conditioning system, especially if it is not in use for a long time. The damp and dark interior parts of the AC are an ideal breeding ground for them. Pungent smells emanating from your AC is an indication that there are germs in it. If left untreated, these germs can grow rapidly. In order to alleviate this problem, it is important to take your vehicle to an auto technician. He or she will inspect the air conditioning system and flush out the germs to eliminate the bad odor. 

Low level of refrigeration

The refrigerant plays an important role in the AC of your car. As the days go by, the level of refrigerant diminishes. It diminishes by about fifteen per cent every year. This loss tends to be greater in the winter season. When you are not using the AC system, seals may dry out and affect its productivity. This will cause the AC to consume the refrigerant quicker. If you notice a problem with the refrigerant of the AC, you can take it to a professional who repairs car air conditioning systems in Alexandria. He or she can refill the gas in the refrigerant tanks or fix any noticeable leakage. 

Soiled Condenser

The role of the condenser in the AC of your car is to cool the high-pressure refrigerant vapors that exit from the compressor. A condenser can get blocked as a result of dirt, debris or grime thus constricting the air flow, therefore, hindering cooling. To rectify this problem, an auto technician will use a good quality flushing agent, which vaporizes easily without leaving residue in the system. The professional can also replace a worn out condenser. 

The above are just a few of the common problems that you should look out for. It is advisable to hire a licensed and experienced professional who offers AC repair services in Alexandria if you notice any of these issues.
