Mercedes-Benz S550 A/C Repair

Few things are worse than a broken car air conditioner on a hot summer day. Is that a hot stove? Nope, just your steering wheel. Sweat soaks the driver's seat. “Who can fix my Mercedes-Benz S550 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 technicians are qualified to diagnose and repair 2011 Mercedes-Benz S550 A/C systems. Bring your Mercedes-Benz S550 to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2011 Mercedes-Benz S550 A/C system to evaluate what repairs are necessary (if any). 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 S550 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.

S550 A/C Recharge

When we perform an A/C repair on your 2011 Mercedes-Benz S550, 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 after one final test to be sure the system is cooling properly, you’re good to go. Our technicians are trained to efficiently perform 2011 Mercedes-Benz S550 A/C recharges.

Troubleshooting Mercedes-Benz S550 A/C Problems

Hot air is a common Mercedes-Benz S550 A/C problem, but it’s not the only issue you might encounter. Another common A/C problem is weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. An A/C system that starts off blowing cold air but then turns warm may suggest a leak, a blown fuse, or a damaged compressor clutch. And smelly A/C in a 2011 Mercedes-Benz S550? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our trained technicians will do what they can to solve your A/C problems. So, chill out. We're here to help you get the blast back in your S550’s A/C!

Frequently Asked Questions for 2011 Mercedes-Benz S550 A/C Systems

  • How can I make my S550 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.
  • Why is my S550 A/C blowing hot 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? 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 S550’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 S550 use gas? Your S550’s A/C uses some power from the engine to run. So, while your air conditioning system may not directly use gasoline as a fuel source, using the A/C can indirectly affect your vehicle’s fuel efficiency.
  • What does it mean if the A/C in my S550 smells like vinegar? It’s easy for moisture to accumulate in your car’s air conditioning system, which can cause microorganisms like bacteria to grow. In turn, this bacteria growth can cause the A/C in your S550 to produce a vinegary odor.
  • What is causing my S550’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 S550’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.
