A/C Repair Service for Your Mercedes-Benz GLS550

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Is that a hot stove? Nope, just your steering wheel. That puddle in the driver’s seat? Sweat. Ugh. You wipe your brow and wonder, "Who can fix the A/C in my Mercedes-Benz GLS550?" Firestone Complete Auto Care can! We know our way around Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2019 Mercedes-Benz A/C systems. Steer your Mercedes-Benz GLS550 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2019 Mercedes-Benz GLS550 A/C system to see if repair work is required. We’ll test overall system performance, check for any leaks, and measure the system pressure. If we suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. A "sniffer" is a machine that's run along parts of your Mercedes-Benz GLS550 A/C system that can detect refrigerant fumes escaping from the system. If your A/C system has a leak, we’ll find and repair it.

A/C Recharge for Mercedes-Benz GLS550

While your 2019 Mercedes-Benz GLS550’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. Then, they’ll use Mercedes-Benz’s specifications to evacuate the system. To finish, we’ll add new refrigerant to recharge the A/C system, and once the technician tests the cool blast for themselves, you’re all set. Our technicians are trained to efficiently perform 2019 Mercedes-Benz GLS550 A/C recharges.

Other Mercedes-Benz GLS550 A/C Problems

Hot air is a common Mercedes-Benz GLS550 A/C problem, but it’s not the only issue you might encounter. Typical A/C problems also include weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. Are you breathing in some “interesting” new odors in your 2019 Mercedes-Benz GLS550? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. Our trained technicians will do what they can to solve your A/C problems. Don’t sweat it — we’re here to help you chill out again in your GLS550.

2019 Mercedes-Benz GLS550 A/C System FAQs

  • Can I make my GLS550 air conditioner colder? For starters, use a sun-blocking shade in the windshield while you’re parked, or look for a shady parking spot. Closing all the passenger vents in your car can help redirect cold air toward you, cooling you off faster. Still need more chill? Head to Firestone Complete Auto Care for an A/C performance check and recharge.
  • What’s making my GLS550 A/C put out warm air? Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.
  • How does my A/C system get a leak? A/C system leaks are often due to a combination of age and moisture. Rubber seals and gaskets naturally degrade over time, allowing refrigerant to exit and moisture to enter your GLS550's A/C system.
  • Does my GLS550 A/C run on gas? While your vehicle’s A/C system doesn’t directly use fuel, it does draw power from the engine, which can impact the fuel consumption of your GLS550.
  • Why does the A/C in my GLS550 smell like vinegar? If a vinegar-like odor comes from your A/C, bacteria growth could be the culprit. Moisture accumulation in the air conditioning system of your GLS550 creates a breeding environment for microorganisms.
  • What is causing my GLS550’s A/C to only work when the car is in motion? If your A/C only works when the vehicle is moving, there could be a problem with part of your GLS550’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.
