Frequently Asked Questions

Find answers to common questions about our aftertreatment and engine cleaning services

The frequency depends on several factors including driving conditions, vehicle usage, and fuel quality. Typically, we recommend cleaning every 100,000-150,000 miles for highway trucks, and more frequently (every 50,000-75,000 miles) for trucks with stop-and-go city driving. However, if you notice symptoms like reduced power, poor fuel economy, or warning lights, you should have it inspected immediately.

Common symptoms include: DPF warning light on the dashboard, reduced engine power (limp mode), increased fuel consumption, excessive black smoke from the exhaust, frequent regeneration cycles, and difficulty starting. If you experience any of these, contact us for diagnostics.

Our standard DPF cleaning service typically takes 24-48 hours from drop-off to completion. This includes removal, cleaning, testing, and reinstallation. For urgent situations, we offer expedited service options. Contact us to discuss your specific timeline needs.

Yes! We understand that downtime is costly. We offer mobile diagnostic services where our technicians come to your location with portable equipment. For cleaning and replacement services, the DPF typically needs to be removed and brought to our facility. Contact us to discuss mobile service options for your fleet.

We stand behind our work with comprehensive warranties. DPF cleaning services include a 12-month/100,000-mile warranty. Replacement filters come with manufacturer warranties ranging from 1-2 years depending on the brand. All labor is warranted for 90 days. Details are provided with each service.

Costs vary depending on the service needed and your vehicle make/model. Diagnostic services start around $150-200. Cleaning typically ranges from $400-800. Replacement costs depend on filter type (OEM vs. aftermarket) and range from $1,500-3,500 including parts and labor. Contact us for a free, no-obligation quote specific to your truck.

Hydrogen cleaning is an advanced, non-destructive cleaning method that uses hydrogen gas to safely remove carbon, ash, and particulate buildup from DPF filters. The hydrogen reacts with the deposits at a molecular level, breaking them down without damaging the filter substrate. This state-of-the-art technology is more effective than traditional thermal cleaning and extends the life of your filter significantly.

Yes, hydrogen cleaning is extremely safe. Unlike high-temperature thermal regeneration methods that can damage the filter substrate, hydrogen cleaning operates at lower temperatures and is completely chemical-free. It's EPA-approved and non-destructive, meaning there's no risk of thermal stress or material degradation. Your filter emerges cleaner and more durable than before.

Hydrogen cleaning offers several key advantages: (1) More thorough cleaning - removes stubborn ash and carbon buildup that traditional methods miss; (2) Extends filter life - reduces need for premature replacement, saving you money; (3) Safer process - no thermal stress or filter damage; (4) Faster regeneration cycles after cleaning; (5) Better fuel economy restoration; (6) Lower risk of DPF failure post-cleaning. It's the most advanced cleaning technology available today.

Hydrogen cleaning is compatible with virtually all diesel truck DPF systems manufactured in the last 15+ years. Whether you drive a Cummins, Duramax, Powerstroke, or other diesel engine, we can apply hydrogen cleaning technology. During your initial diagnostic, our technicians will determine if hydrogen cleaning is the best solution for your specific vehicle and filter condition.
