How do I make my Sierra 2500 HD air conditioning 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 2500 HD A/C blowing hot air?

Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.

How does my A/C system get a leak?

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 2500 HD’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does running the A/C in my Sierra 2500 HD use gasoline?

While your vehicle’s A/C system doesn’t directly use fuel, it does draw power from the engine, which can impact the fuel consumption of your Sierra 2500 HD.

Why does my Sierra 2500 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 2500 HD to have a vinegar-like smell.

Why does my Sierra 2500 HD’s A/C only work when the car is moving?

There could be issues with one or more components in the air conditioning or electrical system. Your Sierra 2500 HD may have a faulty cooling fan or low refrigerant.

In this A/C performance inspection, we’ll check out the current condition of your 2013 GMC Sierra 2500 HD A/C system to determine whether repair work is needed. This check will include an examination of system pressure, a visual inspection, and a leak test. If any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called a “sniffer.” What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your GMC Sierra 2500 HD A/C system to detect any refrigerant fumes that might be leaking out from the system. If your system has a leak, we can get it fixed.

A/C Recharge for GMC Sierra 2500 HD

Let's say we repair your 2013 GMC Sierra 2500 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. Next, they will evacuate the system according to GMC's recommendations. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you’re good to go. Our technicians are trained to efficiently perform 2013 GMC Sierra 2500 HD A/C recharges.

Troubleshooting GMC Sierra 2500 HD A/C Problems

Hot air is a common GMC Sierra 2500 HD A/C problem, but it’s not the only issue you might encounter. 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 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. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2013 GMC Sierra 2500 HD? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. 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 2500 HD.
