Frequently Asked Questions
What are common signs of air conditioning problems in heavy vehicles?
If your cabin isn’t cooling effectively, blows warm air or has weak airflow, it may indicate issues like low refrigerant, a blocked filter or a failing compressor. Other warning signs include unusual noises when the A/C is running or a musty odour from the vents. These problems often worsen over time and can lead to complete system failure. Early diagnosis and repair can prevent costly downtime and further damage.
How often should heavy vehicle air conditioning be serviced?
Heavy vehicle air conditioning systems should typically be serviced every 12 to 24 months, depending on usage and operating conditions. Regular servicing helps maintain cooling efficiency, prevent compressor failure, check for leaks and ensure filters and refrigerant levels are functioning correctly to keep drivers safe and comfortable.
Can I regas my heavy vehicle air con myself?
While DIY regassing kits exist, it’s not recommended for heavy vehicles. These systems are complex and require proper tools, gauges and refrigerant handling knowledge. Incorrect regassing can lead to system damage or legal issues due to environmental regulations. It’s safer and more effective to have a licensed technician perform the regas.
