Auto AC Service: 3 Critical Signs Your Vehicle's Air Conditioner Needs Professional Servicing

Posted on: 11 December 2020

Most people never notice the significance of their vehicles' air conditioning systems until they start malfunctioning, leading to uncomfortable drives. A well-functioning air conditioner regulates temperatures in the car according to your needs, which allows you to enjoy comfort when driving. However, it is essential to know how to detect problems affecting your AC and solve them before they escalate. Here are three critical signs your vehicle's AC needs professional servicing:

Constant High Temperatures in the Car

The first obvious sign that your auto's AC is failing is when your car's temperature becomes unbearable. Different factors can make the AC not to cool your vehicle as expected. They include a clogged filter, radiator issues, leaking refrigerant, faulty cooling fans, a clogged or damaged condenser or a defective compressor.

If your car's temperature is high all of a sudden, place your hands near the AC vents to inspect it. If it's blowing hot air, you need to take your vehicle to the nearest auto shop for professional servicing.

Strange Smell From the AC

If you notice a strange musty smell when you turn your AC on, it might be due to mould growth or the presence of bacteria in the vents. Mould thrives in environments with high moisture content. Therefore, if your AC is experiencing leakage, insufficient airflow or condensation, there is a high possibility of mould growth.

Mould is hazardous because it can cause respiratory complications. For this reason, it is advisable to hire an auto AC service before the issue escalates.

Strange Noise From the AC

A failing AC will produce a screeching, rattling, buzzing, hissing or knocking sound. If your air conditioner makes a screeching or squealing sound, the problem stems from the serpentine or drive belt, which provides power for the AC. When the belt is worn-out or cracked, it will cause the AC to produce noise.

A rattling noise is from a damaged AC compressor or failing bearings of the idler pulley. If you hear a buzzing noise, that means your AC is overcharged or the compressor is not functioning correctly. A hissing sound from the air conditioner after turning off your vehicle indicates that your car is equalising pressure. However, you should be alarmed if the noise is continuous. Knocking noises are from loose AC components.

If you want to protect the structural integrity of your car's AC, you must observe regular repair and maintenance. Some of the maintenance practices you need to observe include running it for about ten minutes weekly to maintain gas pressure, cleaning the air filters and recharging it routinely. If the AC is faulty, it is advisable to hire an experienced contractor to examine its condition and offer the necessary solutions.
