Mobile A/C Service for Trucks and Trailers

We specialize in on-site A/C diagnostics and repairs for a wide range of diesel truck and trailer systems. We work directly at your location, eliminating the need to schedule shop time or take vehicles out of service longer than necessary.

 

Our A/C services include:

● mobile diagnostics for heating and cooling systems

● A/C system repairs for trucks and trailers

● refrigerant charging completed after proper diagnosis

● on‑site service anywhere in Jacksonville or New Brunswick

 

This approach is ideal for fleets, owner-operators, and drivers passing through the province who need dependable A/C service without delays.

A/C Diagnostics – The Starting Point for Proper Repairs

Accurate diagnostics are essential for effective A/C repairs. Just adding refrigerant without identifying the root cause may mean failing to address the actual issue and cause poor performance, repeated breakdowns, or further system damage.

 

We begin every A/C service call with a thorough on-site diagnosis to assess your system performance and identify any issues affecting cooling or heating efficiency.

 

Our diagnostic process focuses on evaluating overall A/C system performance so we can identify why it’s not cooling properly. We check the system operation before conducting repairs so that we may pinpoint any faults that affect reliability. This reduces guesswork, prevents unnecessary effort, and ensures that the right repairs are done the first time.

A/C Repairs for Trucks and Trailers

Once the issue is identified, our technicians complete the necessary A/C system repairs to restore proper operation. We service both truck and trailer A/C systems, addressing a wide range of cooling system faults that impact driver comfort and safety.

 

Our A/C repair services include:

● repairing components affecting A/C performance

● addressing cooling system faults

● restoring proper airflow and temperature control

● ensuring reliable heating and cooling operation

 

Whether the A/C system is underperforming or not functioning at all, you can count on us for practical, dependable repair solutions.

Refrigerant Charging

Refrigerant charging is one of the most requested A/C services and a critical part of maintaining proper system performance. However, charging should only be completed after the system has been properly diagnosed.

 

Priority Diesel provides refrigerant charging as part of complete A/C service, ensuring:

● the system is evaluated before charging

● the correct refrigerant level is restored

● cooling performance meets operational requirements

 

Proper refrigerant charging helps maintain efficient cooling, prevents excessive strain on your A/C components, and supports consistent comfort during long hauls.
