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 take a deep breath and ask yourself, “Who can fix my GMC Sierra 3500 HD A/C?” Firestone Complete Auto Care — that’s who! We know our way around GMC vehicles, and our technicians are qualified to diagnose and repair 2012 GMC Sierra 3500 HD A/C systems. Steer your GMC Sierra 3500 HD to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2012 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 refrigerant fumes escaping 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

While your 2012 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. The A/C system is recharged with new refrigerant and once we’ve done a final test on the system ourselves, you’re good to go. Our technicians know how to keep your A/C in tip-top shape with 2012 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. Another common A/C problem is 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 2012 GMC Sierra 3500 HD? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. Don’t sweat it — we’re here to help you chill out again in your Sierra 3500 HD.

Frequently Asked Questions for 2012 GMC Sierra 3500 HD A/C Systems

  • How 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.
  • What’s making my Sierra 3500 HD A/C put out warm 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? To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your Sierra 3500 HD’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Does the A/C in my Sierra 3500 HD rely on gas? 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.
  • My Sierra 3500 HD’s A/C smells like vinegar! What can cause that? 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 3500 HD to produce a vinegary odor.
  • Why won’t my Sierra 3500 HD’s A/C cool the vehicle when the car is stopped? 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.
