How can I make my S450 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.

What’s making my S450 A/C put out warm air?

An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.

What can cause an A/C system 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 S450’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does running the A/C in my S450 use gasoline?

The air conditioning system in your S450 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.

My S450’s A/C smells like vinegar! What can cause that?

If the air conditioning in your S450 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 vehicle have to be moving for my S450’s A/C to work?

There could be issues with one or more components in the air conditioning or electrical system. Your S450 may have a faulty cooling fan or low refrigerant.

A/C Service for Mercedes-Benz S450

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 wipe your brow and wonder, "Who can fix the A/C in my Mercedes-Benz S450?" Easy — Firestone Complete Auto Care! We know our way around Mercedes-Benz vehicles, and our technicians are qualified to diagnose and repair 2020 Mercedes-Benz S450 A/C systems. Come to your local Firestone Complete Auto Care in your Mercedes-Benz S450

During this initial A/C performance check, we’ll look at the state of your 2020 Mercedes-Benz S450’s A/C system to evaluate what repairs are necessary (if any). This check will include an examination of system pressure, a visual inspection, and a leak test. If we suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. 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 detect any refrigerant fumes that might be leaking out from the system. If your system has a leak, we can get it fixed.

S450 A/C Recharge

While your 2020 Mercedes-Benz S450’s air conditioner is being serviced, 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. 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 ready to get back on the road. Our technicians know how to keep your A/C in tip-top shape with 2020 Mercedes-Benz S450 A/C recharges.

Other Mercedes-Benz S450 A/C Problems

You may think warm air is the only potential Mercedes-Benz S450 A/C problem you’ll have, but you may notice other issues, too. Other common A/C problems include weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. 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 2020 Mercedes-Benz S450? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. 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 S450’s A/C!
