During this initial A/C performance check, we’ll look at the state of your 2021 GMC Sierra 3500 HD’s A/C system to evaluate what repairs are necessary (if any). We’ll test overall system performance, check for any leaks, and measure the system pressure. If we think there might be a leak, we'll run a special U/V dye through the system or use a "sniffer." 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 identify points where refrigerant fumes could be escaping the system. If your system has a leak, we can get it fixed.
While your 2021 GMC Sierra 3500 HD’s air conditioner is being serviced, we’ll also do 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. 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. We want you to be comfortable in your car, so we train our technicians to perform 2021 GMC Sierra 3500 HD A/C recharges.
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 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 suggest a leak, a blown fuse, or a damaged compressor clutch. Are you breathing in some “interesting” new odors in your 2021 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 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!
