Why Is My AC Running but Not Cooling in My Truck?

If your truck's AC is running but not providing the cool breeze you need, it's likely due to a refrigerant leak. This leads to improper cooling and can seriously affect your driving comfort. To address this issue, our experts conducted a comprehensive inspection to identify and fix any leaks. 

Why Is My Truck AC Warm at Idle?

Experiencing warm air from your truck's AC when idle can be frustrating. This may indicate a problem with the AC system's high-pressure hose or, in some cases, a malfunctioning AC compressor. Our team will diagnose the issue and perform the necessary repairs, ensuring your AC functions optimally, even at idle.

Truck AC Repair in Plaistow, NH

At Tri-State Diesel Repair, we offer a range of HVAC repairs tailored for heavy-duty trucks:

Refrigerant Recharge: If your AC isn't cooling as it should, a refrigerant recharge might be the solution. Our experts will replenish the refrigerant to the correct level, restoring your AC's cooling performance.

Condenser Replacement: A damaged or clogged condenser can hinder proper cooling. We will replace your truck's condenser with a high-quality replacement to ensure efficient heat transfer and optimal cooling.

Compressor Repair: The AC compressor plays a crucial role in the system's functionality. We provide expert repairs and, if necessary, replacement services to keep your AC running smoothly.
