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.

What’s making my Sierra 2500 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.

How does my A/C system get a leak?

Over the years, the rubber seals and gaskets in your Sierra 2500 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 my Sierra 2500 HD A/C use gas?

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.

What does it mean if the A/C in my Sierra 2500 HD smells like vinegar?

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.

What is causing my Sierra 2500 HD’s A/C to only work when the car is in motion?

Damaged or worn components in your Sierra 2500 HD’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

GMC Sierra 2500 HD A/C Repair

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 2500 HD A/C?” Easy — Firestone Complete Auto Care! We know GMC vehicles, and our trained technicians can identify and repair issues with 2017 GMC A/C systems. Steer your GMC Sierra 2500 HD to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2017 GMC Sierra 2500 HD A/C system to determine whether repair work is needed. This check includes a visual inspection, performance test, and pressure and 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 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 2500 HD

While your 2017 GMC Sierra 2500 HD’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per GMC guidelines. To finish, we’ll add new refrigerant to recharge the A/C system, and once the technician tests the cool blast for themselves, you're ready to get back on the road. We want you to be comfortable in your car, so we train our technicians to perform 2017 GMC Sierra 2500 HD A/C recharges.

Troubleshooting GMC Sierra 2500 HD A/C Problems

Warm air isn't the only GMC Sierra 2500 HD A/C problem you may encounter. Another common A/C problem is weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. 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. And smelly A/C in a 2017 GMC Sierra 2500 HD?

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 2500 HD’s A/C!
