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?

If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.

How does my A/C system get a leak?

A/C system leaks are often due to a combination of age and moisture. Rubber seals and gaskets naturally degrade over time, allowing refrigerant to exit and moisture to enter your S550's A/C system.

Does my S550 A/C use gas?

S550 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.

What can cause the A/C in my S550 to smell like vinegar?

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 does my vehicle have to be moving for my S550’s A/C to work?

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.

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?

S550 A/C Recharge

When we perform an A/C repair on your 2010 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. Next, they will evacuate the system according to Mercedes-Benz's recommendations. 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 all set. Our technicians know how to keep your A/C in tip-top shape with 2010 Mercedes-Benz S550 A/C recharges.

Troubleshooting 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. 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 your A/C system blows cold air first but then it turns warm, this can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. And smelly A/C in a 2010 Mercedes-Benz S550? 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. So, chill out. We're here to help you get the blast back in your S550’s A/C!
