A/C Service for 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. Sweat soaks the driver's seat. You wipe your brow and wonder, "Who can fix the A/C in my GMC Sierra 3500 HD?" Easy — Firestone Complete Auto Care! We know GMC vehicles, and our technicians are qualified to diagnose and repair 2017 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 2017 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 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 3500 HD A/C system to detect refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

Recharge the A/C in Your Sierra 3500 HD

While your 2017 GMC Sierra 3500 HD’s air conditioner is being serviced, we’ll also do 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 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 ready to get back on the road. Our technicians know how to keep your A/C in tip-top shape with 2017 GMC Sierra 3500 HD A/C recharges.

Common 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. 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 2017 GMC Sierra 3500 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 technicians will work to solve your A/C problems to the best of their ability. Don’t sweat it — we’re here to help you chill out again in your Sierra 3500 HD.

2017 GMC Sierra 3500 HD A/C System FAQs

  • Can I make my Sierra 3500 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 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 can cause an A/C system leak? 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 my Sierra 3500 HD A/C run 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.
  • Why does my Sierra 3500 HD have a vinegary smell coming from the A/C? Moisture can accumulate on your vehicle’s A/C system components, creating the perfect breeding ground for bacteria. As this bacteria grows, it can cause the air conditioning system in your Sierra 3500 HD to have a vinegar-like smell.
  • Why won’t my Sierra 3500 HD’s A/C cool the vehicle when the car is stopped? A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your Sierra 3500 HD is moving. You may be low on refrigerant, or the cooling fan could be faulty.
