Mercedes-Benz S450 A/C Repair

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Your steering wheel feels like it's burning your hands. Sweat soaks the driver's seat. “Who can fix my Mercedes-Benz S450 A/C?” you wonder, as the sun beats through the windshield. Easy — Firestone Complete Auto Care! We’ve got experience with Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2018 Mercedes-Benz A/C systems. Come to your local Firestone Complete Auto Care in your Mercedes-Benz S450

In this A/C performance inspection, we’ll check out the current condition of your 2018 Mercedes-Benz S450 A/C system to determine whether repair work is needed. This check includes a visual inspection, performance test, and pressure and leak test. 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.” What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your Mercedes-Benz S450 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 S450

When we perform an A/C repair on your 2018 Mercedes-Benz S450, 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. The A/C system is recharged with new refrigerant and once the technician tests the cool blast for themselves, 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 S450 A/C recharges.

Other Mercedes-Benz S450 A/C Problems

Warm air isn't the only Mercedes-Benz S450 A/C problem you may 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. 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 2018 Mercedes-Benz S450? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our trained technicians will do what they can to solve your A/C problems. We’re here to help you get back on the road in your S450 — without all the sweat puddles!

Frequently Asked Questions for 2018 Mercedes-Benz S450 A/C Systems

  • How can I make my S450 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 S450 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? Over the years, the rubber seals and gaskets in your S450’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 S450 rely on gas? Your S450’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 can cause the A/C in my S450 to 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 S450 creates a breeding environment for microorganisms.
  • Why does my vehicle have to be moving for my S450’s A/C to work? A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your S450 is moving. You may be low on refrigerant, or the cooling fan could be faulty.
