A/C Repair Service for Your GMC Sierra 3500 HD

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like it's burning your hands. That puddle in the driver’s seat? Sweat. Ugh. You wipe your brow and wonder, "Who can fix the A/C in my GMC Sierra 3500 HD?" Firestone Complete Auto Care — that’s who! We’ve got experience with GMC vehicles, and our technicians are qualified to diagnose and repair 2020 GMC Sierra 3500 HD A/C systems. Steer your GMC Sierra 3500 HD to your nearest Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 2020 GMC Sierra 3500 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 think there might be a leak, we'll run a special U/V dye through the system or use a "sniffer." 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 your A/C system has a leak, we’ll find and repair it.

Recharge the A/C in Your Sierra 3500 HD

Let's say we repair your 2020 GMC Sierra 3500 HD 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 GMC's recommendations. Finally, we’ll recharge the A/C system with new refrigerant and once the technician tests the cool blast for themselves, you’re all set. Our technicians are trained to efficiently perform 2020 GMC Sierra 3500 HD A/C recharges.

Other GMC Sierra 3500 HD A/C Problems

You may think warm air is the only potential GMC Sierra 3500 HD A/C problem you’ll have, but you may notice other issues, too. Other common A/C problems 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 you notice that your A/C system’s air is cold at first, then quickly goes warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. Are you breathing in some “interesting” new odors in your 2020 GMC Sierra 3500 HD? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Technicians at Firestone Complete Auto Care are ready to help you address 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!

2020 GMC Sierra 3500 HD A/C System FAQs

  • 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? 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.
  • What can cause an A/C system leak? Over the years, the rubber seals and gaskets in your Sierra 3500 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 the A/C in my Sierra 3500 HD rely on gas? Your Sierra 3500 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 can cause the A/C in my Sierra 3500 HD 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 Sierra 3500 HD creates a breeding environment for microorganisms.
  • What is causing my Sierra 3500 HD’s A/C to only work when the car is in motion? If your A/C only works when the vehicle is moving, there could be a problem with part of your Sierra 3500 HD’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.
