According to WPLN.org, 2024 was Nashville, Tennessee’s hottest year on record. Indeed, the last 10 years have been among the city’s top 20 warmest.

Things could be pretty much the same this year, something you’re likely to feel and experience as you drive around town in your European car.

It could be much worse, though, if your vehicle’s air conditioner fails to regulate and cool the cabin temperature. You’d want to search for “AC repair near me” ASAP in this case, as prolonged driving in a hot environment can put your ride at a higher risk of overheating. It can also put you and your passengers (especially kids and pets) in harm’s way.

To that end, the European vehicle pros at Rennstahl put together this guide. Read on to discover the top signs you need AC repair (and how our auto AC service experts can help). 

1. Weak Airflow

The National Weather Service says that extreme heat is the number one weather-related killer in the United States. It also causes hundreds, even thousands, of heat-related illnesses (HRIs) each year.

Being inside an air-conditioned vehicle is much better than being outdoors at the mercy of the sun’s heat and UV rays. The problem is that if a car’s AC doesn’t work and produces little to no cool air, being inside it can be very dangerous.

As The Columbus Dispatch explains, a car’s temperature can reach 109°F within just 20 minutes during an 80-degree day. Within an hour, it can reach scorching heights of up to 123°F.

If the air from your European vehicle’s air vents isn’t as strong as it should be, it could indicate a problem with the air conditioning system’s ability to circulate air. From a clogged cabin air filter to ductwork problems and faulty blower motors, these are some potential culprits behind this AC problem.

In this case, don’t delay bringing your vehicle to a trustworthy European auto repair shop like Rennstahl. Our factory-trained mechanics are highly knowledgeable, skilled, and experienced in repairing precision-engineered European cars, from Audi to Aston Martin, BMW, Maserati, and Volkswagen, to name a few. We’ve also invested in and are adept at state-of-the-art diagnostic tools that allow us to pinpoint the root of the issue accurately without any guesswork.

2. Insufficient or Poor Cooling

Is your European car’s air conditioning system not producing air as cold as you want it to be? Perhaps it’s even blowing out warm instead of cool air! In this case, your vehicle’s AC system could be experiencing issues affecting various components, such as the:

• Refrigerant
• Condenser or evaporator coils
• Air filter

A refrigerant leak is among the most common reasons for inadequate or poor cooling in vehicle air conditioners.

Just like your home’s air conditioner, your car’s AC relies on refrigerant to absorb heat and moisture from the air. The cold evaporator coils then cool this air down, while the condenser coils release the heat that the refrigerant has absorbed.

A vehicle cooling system with a refrigerant leak won’t be able to cool the air effectively. Problems with the condenser and evaporator coils can also lead to reduced cooling efficiency. Clogged air filters can exacerbate the problem by restricting airflow.

If you notice this symptom, it’s time to partner with a trusted mechanic for specialized European vehicle care, car AC maintenance, or potential repairs.

3. Odd Noises

A car air conditioning system that makes unusual noises warrants a closer inspection from a highly experienced mechanic. An example is if you can hear bubbling or hissing sounds when the compressor runs. In this case, you may have a leaking refrigerant line in your hands.

Other odd noises originating from the AC compressor that could signal air conditioning problems with your European vehicle are:

• Grinding
• Rattling
• Squealing

Don’t wait for those sounds to worsen and result in a full-blown AC system breakdown. If you’re in Nashville, TN, or the surrounding area, rely on our team at Rennstahl to perform our comprehensive vehicle diagnostic process. We’ll use our skills, knowledge, and state-of-the-art equipment to determine and fix what’s wrong with your ride.

4. Foul or Odd Smells

Foul smells from your car’s air conditioning vents can indicate moisture-related bacterial and mold growth or fluid leaks.

If the odor is musty or mildewy (like old bread or cheese or wet socks), it signals mold and bacteria build-up, something that can happen if you don’t use the AC often or haven’t changed its filters for a long time. If it smells like rotten eggs, it could indicate a problem with the fuel system or a leak originating from the catalytic converter.

Have your European car’s air conditioning system checked by the pros here at Rennstahl. We’ll give your ride a thorough inspection and address the root cause of the problem.

5. Water Leaks

As you operate your vehicle’s air conditioning system, it will generate some condensation as it extracts heat and moisture from the air. However, it shouldn’t drip excessively to the point that it creates puddles under the dashboard or around the engine compartment. If it does, it indicates that something is wrong with the condensate drainpipe, forcing the water to back up and leak inside your ride.

Unaddressed, a clogged or disconnected drainpipe can lead to more problems, such as mold growth, poor AC performance, or even AC breakdown. Prevent this from happening by having your European vehicle undergo servicing or repairs.
