A/C Repair Service for Your GMC Sierra 3500 HD

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like lava. That puddle in the driver’s seat? Sweat. Ugh. “Who can fix my GMC Sierra 3500 HD A/C?” you wonder, as the sun beats through the windshield. Easy — Firestone Complete Auto Care! We know GMC vehicles, and our trained technicians can identify and repair issues with 2018 GMC A/C systems. Bring your GMC Sierra 3500 HD to your local Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 2018 GMC Sierra 3500 HD A/C system to see if repair work is required. 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 GMC Sierra 3500 HD A/C system to detect any refrigerant fumes that might be leaking out from the system. If there's a leak, we'll find it and fix it.

Sierra 3500 HD A/C Recharge

Let's say we repair your 2018 GMC Sierra 3500 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. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per GMC guidelines. Finally, we’ll recharge the A/C system 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 GMC Sierra 3500 HD A/C recharges.

Other GMC Sierra 3500 HD A/C Problems

Warm air isn't the only GMC Sierra 3500 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 you notice that your A/C system’s air is cold at first, then quickly goes warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. Are you breathing in some “interesting” new odors in your 2018 GMC Sierra 3500 HD? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. 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 Sierra 3500 HD’s A/C!

Questions About 2018 GMC Sierra 3500 HD A/C Systems

  • Can I make my Sierra 3500 HD 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 is my Sierra 3500 HD 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.
  • What causes A/C system leaks? 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 Sierra 3500 HD's A/C system.
  •  Does running the A/C in my Sierra 3500 HD use gasoline? Sierra 3500 HD 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 does it mean if the A/C in my Sierra 3500 HD smells like vinegar? If the air conditioning in your Sierra 3500 HD 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 Sierra 3500 HD’s A/C to work? There could be issues with one or more components in the air conditioning or electrical system. Your Sierra 3500 HD may have a faulty cooling fan or low refrigerant.
