Mercedes-Benz S550 A/C Repair

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like it's burning your hands. Your skin sticks to the driver’s seat. You wipe your brow and wonder, "Who can fix the A/C in my Mercedes-Benz S550?" Easy — Firestone Complete Auto Care! We know Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2009 Mercedes-Benz. 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 2009 Mercedes-Benz S550 A/C system to see if repair work is required. This check will include an examination of system pressure, a visual inspection, and a leak test. If we think there might be a leak, we'll run a special U/V dye through the system or use 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 there's a leak, we'll find it and fix it.

Recharge the A/C in Your S550

When we perform an A/C repair on your 2009 Mercedes-Benz S550, we’ll also do an A/C evacuation and recharge. To do this, one of our technicians will remove the refrigerant in your A/C system (if there is even any left to remove). Next, they will evacuate the system according to Mercedes-Benz's recommendations. Finally, we’ll recharge the A/C system with new refrigerant and once we’ve done a final test on the system ourselves, you’re good to go. We want you to be comfortable in your car, so we train our technicians to perform 2009 Mercedes-Benz S550 A/C recharges.

Common Mercedes-Benz S550 A/C Problems

You may think warm air is the only potential Mercedes-Benz S550 A/C problem you’ll have, but you may notice other issues, too. Typical A/C problems also include weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. 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. Are you breathing in some “interesting” new odors in your 2009 Mercedes-Benz S550? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our technicians will work to solve your A/C problems to the best of their ability. So, chill out. We're here to help you get the blast back in your S550’s A/C!

Questions About 2009 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 do I get hot air from my S550 A/C? 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? Over the years, the rubber seals and gaskets in your S550’s A/C system naturally degrade. Moisture can get into the system and cause a malfunction, or parts can simply wear out so that your system no longer seals properly.
  •  Does the A/C in my S550 use 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 S550.
  • Why does my S550 have a vinegary smell coming from the A/C? If the air conditioning in your S550 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 won’t my S550’s A/C cool the vehicle when the car is stopped? Damaged or worn components in your S550’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.
