Heavy-duty trucks work hard—and so do their cooling systems. Look out for these common warning signs that your AC system is struggling:
- Weak airflow, even at full blast
- Warm air blowing instead of cold
- Musty or moldy smells from the vents
- Water leaking inside the cab
- AC only works while driving
Early detection helps avoid bigger, costlier issues down the road. If you notice any of these symptoms, bring your truck in for a diagnostic check.
At RG Diesel, LLC, we understand the unique demands placed on diesel truck AC systems, especially those used for towing, hauling, or off-road work. Our team delivers expert repairs and routine maintenance tailored to heavy-duty performance.
Diesel trucks run hotter than gas-powered vehicles and often endure long hours on the road. Regular AC service is essential to prevent cracks, leaks, and compressor failure. Whether you’re hauling, off-roading, or commuting, RG Diesel, LLC will keep your cooling system running strong.
How often should I recharge my diesel truck’s AC system?
Only when refrigerant levels drop or cooling performance fades—typically every 2–4 years, depending on usage.
Why is my truck blowing warm air even after a recharge?
You may have a leak, a failing compressor, or a clogged orifice tube. We’ll inspect the system to find the root cause.
Should I service my AC in the winter?
Yes! Running your AC in winter helps keep seals lubricated and prevents compressor wear.
