How can I make my G550 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.

Why do I get hot air from my G550 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 can cause an A/C system leak?

Over the years, the rubber seals and gaskets in your G550’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.

Is my G550 A/C powered by gas?

The air conditioning system in your G550 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.

What can cause the A/C in my G550 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 G550 creates a breeding environment for microorganisms.

Why does my vehicle have to be moving for my G550’s A/C to work?

Damaged or worn components in your G550’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.

We know our way around Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2018 Mercedes-Benz A/C systems. Bring your Mercedes-Benz G550 to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2018 Mercedes-Benz G550 A/C system to evaluate what repairs are necessary (if any). 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" is a machine that's run along parts of your Mercedes-Benz G550 A/C system that can 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 G550

Let's say we repair your 2018 Mercedes-Benz G550 A/C system. We will also perform an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Next, they will evacuate the system according to Mercedes-Benz's recommendations. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you’re all set. Our technicians know how to keep your A/C in tip-top shape with 2018 Mercedes-Benz G550 A/C recharges.

Common Mercedes-Benz G550 A/C Problems

You may think warm air is the only potential Mercedes-Benz G550 A/C problem you’ll have, but you may notice other issues, too. Typical A/C problems also include 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 may suggest a leak, a blown fuse, or a damaged compressor clutch. Are you breathing in some “interesting” new odors in your 2018 Mercedes-Benz G550? 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 G550 — without all the sweat puddles!
