Key Benefits of This Service

You'll bring your vehicle to our shop where we connect manifold gauges to measure refrigerant pressure on both the high and low sides of the system. This tells us whether you're dealing with a leak, a failing compressor, or a blockage in the expansion valve. We also inspect electrical connections, belts, and the condenser for damage or debris buildup that restricts airflow.


Lonewolf Diesel uses factory-approved refrigerants and follows EPA guidelines during every recharge and leak repair. Certified mechanics ensure proper refrigerant levels and airflow performance. We replace worn compressors, repair leaking hoses, and clean condenser fins to restore full cooling capacity. Each repair is tested under load to confirm the system maintains temperature even during idling or low-speed operation.


After repairs, you'll drive away with cold air blowing consistently from every vent. We provide a detailed report of what was repaired, what caused the failure, and how to maintain optimal AC performance going forward. This proactive approach helps you avoid repeat failures and expensive emergency repairs.

What to Expect When You Book

AC problems are common in hot climates, but many drivers wait too long to address them. Here are answers to frequently asked questions about our AC repair services.

Why does my AC blow cold at first, then turn warm?
This usually indicates a refrigerant leak or a failing compressor clutch. As refrigerant levels drop, the system can't maintain pressure, and cooling performance declines over time.
How often should AC systems be serviced?
We recommend annual inspections before summer to check refrigerant levels, test the compressor, and clean the condenser. This prevents breakdowns during peak heat.
Can you repair AC leaks, or does the whole system need replacement?
Most leaks occur at hose connections, the evaporator, or the condenser and can be repaired without replacing the entire system. We use UV dye and electronic leak detectors to pinpoint the exact location.
Do you work on AC systems for diesel trucks and equipment?
Yes, our team is experienced with the larger AC systems found in heavy-duty trucks and equipment operating in extreme temperatures throughout the oilfield environment.
How long does AC repair typically take?
Simple recharges take about an hour. Compressor replacement or leak repairs may require a few hours, depending on the location of the component and accessibility.
