A/C Repair Service for Your Mercedes-Benz SL550

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like it's burning your hands. Your skin sticks to the driver’s seat. “Who can fix my Mercedes-Benz SL550 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We’ve got experience with Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2018 Mercedes-Benz A/C systems. Steer your Mercedes-Benz SL550 to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2018 Mercedes-Benz SL550’s 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 any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called a “sniffer.” A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Mercedes-Benz SL550 A/C system to identify points where refrigerant fumes could be escaping the system. If your A/C system has a leak, we’ll find and repair it.

Recharge the A/C in Your SL550

Let's say we repair your 2018 Mercedes-Benz SL550 A/C system. We will also perform an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll use Mercedes-Benz’s specifications to evacuate the system. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you're ready to get back on the road. We want you to be comfortable in your car, so we train our technicians to perform 2018 Mercedes-Benz SL550 A/C recharges.

Common Mercedes-Benz SL550 A/C Problems

Hot air is a common Mercedes-Benz SL550 A/C problem, but it’s not the only issue you might encounter. Another common A/C problem is weak airflow, which could mean you have a compromised seal, mildew or mold buildup, a loose or damaged hose, or a ventilation fan that needs to be replaced. If your A/C system blows cold air first but then it turns warm, this can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. And smelly A/C in a 2018 Mercedes-Benz SL550? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. We’re here to help you get back on the road in your SL550 — without all the sweat puddles!

Frequently Asked Questions for 2018 Mercedes-Benz SL550 A/C Systems

  • Can I make my SL550 air conditioner colder? Park in the shade whenever you can, and use a reflective sunshade in the windshield when you’re parked. If you’re the only one in the car, close all the vents except the ones that point toward you. Give the system the final boost it needs with an A/C performance check and recharge from Firestone Complete Auto Care.
  • Why is my SL550 A/C blowing hot air? If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.
  • What causes A/C system leaks? To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your SL550’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Does the A/C in my SL550 rely on gas?  The air conditioning system in your SL550 does not use gasoline directly as a fuel source, but it does require some power from the engine, which indirectly affects your car's fuel consumption.
  • Why does my SL550 have a vinegary smell coming from the A/C? If the air conditioning in your SL550 smells like vinegar, it could be due to bacteria growth on system components such as the evaporator and heater cores. Bacteria can grow when moisture accumulates on air conditioning system components, providing a breeding ground for microorganisms.
  • Why does my SL550’s A/C only work when the car is moving? Damaged or worn components in your SL550’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.
