Our Services
At D&I DPF Cleaning Fresno, we specialize in professional DPF cleaning, DPF repair, emissions system diagnostics, and full diesel truck repair services for owner-operators and fleets throughout California’s Central Valley.
Your Diesel Particulate Filter (DPF) plays a critical role in emissions compliance, engine efficiency, and overall truck performance. Over time, soot and ash accumulate inside the filter, restricting airflow and causing:
Frequent regens
Loss of power
Poor fuel economy
Check engine lights
Engine derate
Advanced DPF Cleaning Technology
We use industry-leading equipment from Filtertherm to ensure thorough, measurable, and repeatable cleaning results.
Our professional cleaning process includes:
Controlled thermal baking to remove carbon buildup
Precision air cleaning to extract ash
Full inspection before and after service
Restoration of proper exhaust flow
This is not a quick blow-out service. Our system is engineered to clean your DPF the way it was designed to be serviced — restoring performance and extending filter life.
DPF CLEANING
Not every DPF issue requires replacement — but when it does, it needs to be done right.
We provide:
DPF diagnostics
DPF removal and installation
DPF replacement (when structurally necessary)
Crack and failure assessments
DOC service and replacement
If your DPF core is melted, cracked, or beyond safe cleaning limits, we offer honest recommendations and high-quality replacement solutions.
DPF REPAIR
Many DPF problems are symptoms of larger emissions system issues. Our experienced technicians diagnose and repair the entire system to prevent repeat failures.
We service and replace:
DEF system components
DOC (Diesel Oxidation Catalysts)
NOx sensors
Pressure sensors
Temperature sensors
EGR-related components
Clamps, gaskets, and exhaust hardware
For emissions parts and components, we trust Redline Emissions Products — known for durability and long-term performance in heavy-duty diesel applications.
We do not cut corners. We install reliable parts designed to keep your truck on the road.
DPF PARTS
While DPF cleaning is a specialty, we provide broader diesel truck repair services to support owner-operators and fleet vehicles.
Our services include:
Emissions system repair
Sensor replacement
DEF diagnostics
Exhaust system service
General diesel repair support
Because we’ve spent over 25 years in the transportation industry, we understand the operational pressures truck owners face daily. Our goal is to fix it right the first time — and get you back on schedule.
TRUCK REPAIRS
Some DPF cleaning services focus on speed alone. We focus on speed and precision.
Our Process
At D&I DPF Cleaning Fresno, we keep the process simple, clear, and built around minimizing downtime. With over 25 years in the transportation industry, we understand that every hour your truck sits is money lost. Here’s exactly how our process works:
-
You contact us by phone or through our website form.
Tell us what your truck is experiencing (check engine light, frequent regens, derate, loss of power, etc.)
Provide basic truck details (make, model, mileage)
Let us know if you're an owner-operator or fleet manager
From there, we’ll either call you back or email you promptly to discuss next steps.
-
When your truck arrives, we perform a complete DPF and emissions system evaluation.
This includes:
Scanning fault codes
Inspecting the DPF for cracks or melting
Checking sensors (NOx, pressure, temperature)
Determining whether cleaning or replacement is needed
Not every DPF needs to be replaced. If it can be professionally restored, we’ll recommend the most cost-effective solution.
You’ll receive a clear estimate and invoice before any work begins.
-
If cleaning is approved, we use advanced equipment from Filtertherm to restore your filter to proper operating condition.
Our professional process includes:
Controlled thermal baking to remove soot and carbon buildup
Precision air cleaning to extract ash
Measured airflow verification
Final inspection before reinstall
This is not a quick blow-out service. It’s a controlled, engineered cleaning process designed for long-term performance.
If replacement parts are required, we use high-quality emissions components from Redline Emissions Products — because we do not cut corners.
-
After cleaning or repair:
The DPF is reinstalled properly
Sensors and components are secured
Fault codes are cleared
System performance is verified
We make sure everything is functioning correctly before your truck leaves our shop.
For fleet clients, we can also coordinate multiple units, structured invoicing, and scheduled maintenance rotations to reduce future downtime.
