Prepare Your Trucks for the Heat with HVAC

RoadForce HVAC Trainings and Tips for Trucks

Keeping drivers cool in spring and summer months is just as critical as keeping them warm in cooler seasons. These cabs are your drivers' offices. Keep them comfortable, productive and content by equipping their trucks with reliable HVAC systems. As a result, you’ll keep driver turnover to a minimum and employee satisfaction as high as possible.

The item that receives the most attention is the compressor, which acts as the “pump” of the system. The compressor keeps refrigerant circulating and increases pressure. The most common causes of compressor failures are:

  • Low refrigerant charge
  • Leaks with the system
  • Contamination in the system
  • Lack of lubrication
  • Clutch failure due to system failure
  • Blockage or restriction within the system
  • Insufficient condenser cooling

Compressors are removed from trucks for these main reasons:

Loss of a refrigerant charge
Low pressure refrigerant entering the compressor on the suction side coming from the evaporator provides cooling to the compressor. With a loss of refrigerant, the compressor overheats and runs dry when oil is not returned back into the compressor.

Particles found inside the compressor will cause internal damage to your system. These particles can cause blockage at the condenser, expansion valve or damage to the internal parts of your compressor. Regular replacement of the filter dryer or accumulator maintains a clean system.

Changing the wrong part is a common procedure in repair A/C failures. The system must be properly diagnosed before changing parts and pieces.

Your bottom line can be dependent on how closely your HVAC system is monitored and maintained. Increase uptime and decrease driver turnover by keeping your HVAC system road ready.
