How do I make my SL550 air conditioning 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 SL550 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.

What causes A/C system leaks?

Over the years, the rubber seals and gaskets in your SL550’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 my SL550 A/C run on gas?

SL550 air conditioning systems don’t use gasoline as a direct fuel source. However, they do rely on engine power, which can indirectly affect your vehicle’s gas mileage.

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.

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. Sweat soaks the driver's seat. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz SL550 A/C?” Easy — Firestone Complete Auto Care! We’ve got experience with Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2014 Mercedes-Benz. Steer your Mercedes-Benz SL550 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2014 Mercedes-Benz SL550 A/C system to determine whether repair work is needed. This check includes a visual inspection, performance test, and pressure and 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 SL550 A/C system to detect any refrigerant fumes that might be leaking out from the system. If your system has a leak, we can get it fixed.

A/C Recharge for Mercedes-Benz SL550

While your 2014 Mercedes-Benz SL550’s air conditioner is being serviced, 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). Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Mercedes-Benz guidelines. To finish, we’ll add new refrigerant to recharge the A/C system, 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 2014 Mercedes-Benz SL550 A/C recharges.

Troubleshooting 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 you notice that your A/C system’s air is cold at first, then quickly goes warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2014 Mercedes-Benz SL550? 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 SL550’s A/C!
