You wipe your brow and wonder, "Who can fix the A/C in my GMC Sierra 2500 HD?" Firestone Complete Auto Care can! We know GMC vehicles, and our qualified technicians can diagnose and service the A/C system in your 2018 GMC. Come to your local Firestone Complete Auto Care in your GMC Sierra 2500 HD

During an A/C performance check, we'll determine the condition of your 2018 GMC Sierra 2500 HD 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 GMC Sierra 2500 HD A/C system to detect any refrigerant fumes that might be leaking out from the system. If your A/C system has a leak, we’ll find and repair it.

Sierra 2500 HD A/C Recharge

Let's say we repair your 2018 GMC Sierra 2500 HD A/C system. We will also perform 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 GMC's recommendations. To finish, we’ll add new refrigerant to recharge the A/C system, 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 2018 GMC Sierra 2500 HD A/C recharges.

Troubleshooting GMC Sierra 2500 HD A/C Problems

Warm air isn't the only GMC Sierra 2500 HD A/C problem you may encounter. 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 your A/C system blows cold air first but then it turns warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2018 GMC Sierra 2500 HD? 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 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 Sierra 2500 HD — without all the sweat puddles!

Questions About 2018 GMC Sierra 2500 HD A/C Systems

  • Can I make my Sierra 2500 HD 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 do I get hot air from my Sierra 2500 HD A/C? 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? Over the years, the rubber seals and gaskets in your Sierra 2500 HD’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 Sierra 2500 HD A/C run on gas? Your Sierra 2500 HD’s A/C uses some power from the engine to run. So, while your air conditioning system may not directly use gasoline as a fuel source, using the A/C can indirectly affect your vehicle’s fuel efficiency.
  • What does it mean if the A/C in my Sierra 2500 HD smells like vinegar? It’s easy for moisture to accumulate in your car’s air conditioning system, which can cause microorganisms like bacteria to grow. In turn, this bacteria growth can cause the A/C in your Sierra 2500 HD to produce a vinegary odor.
  • Why does my Sierra 2500 HD’s A/C only work when the car is moving? Damaged or worn components in your Sierra 2500 HD’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.
  • Where can I get my Sierra 2500 HD’s A/C repaired? Firestone Complete Auto Care has decades of experience inspecting and repairing Sierra 2500 HD air conditioning systems. Schedule an A/C repair appointment at one of our locations near you today.
