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 is my SL550 A/C blowing hot 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.

How does my A/C system get a 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 SL550’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does my SL550 A/C use 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.

What can cause the A/C in my SL550 to smell like vinegar?

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 vehicle have to be moving for my SL550’s A/C to work?

There could be issues with one or more components in the air conditioning or electrical system. Your SL550 may have a faulty cooling fan or low refrigerant.

We know Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2011 Mercedes-Benz. Bring your Mercedes-Benz SL550 to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2011 Mercedes-Benz SL550’s A/C system to determine whether repair work is needed. 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. 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 refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

SL550 A/C Recharge

Let's say we repair your 2011 Mercedes-Benz SL550 A/C system. We will also perform 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. The A/C system is recharged with new refrigerant and once the technician tests the cool blast for themselves, you’re good to go. We want you to be comfortable in your car, so we train our technicians to perform 2011 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 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 2011 Mercedes-Benz SL550? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. Don’t sweat it — we’re here to help you chill out again in your SL550.
