Why Is My Truck AC Not Blowing Cold Air?

Your heavy-duty truck’s AC may not blow cold air due to low refrigerant, a faulty compressor, a clogged condenser, electrical issues, or a malfunctioning expansion valve. Leaks or sensor failures can also affect cooling. A thorough diagnosis is needed to pinpoint and fix the specific cause.

How Often Should Truck HVAC Systems Be Serviced?

Truck HVAC systems in heavy-duty diesel vehicles should be serviced at least once a year or every 12,000 to 15,000 miles. Regular service includes checking refrigerant levels, inspecting components, cleaning filters, and testing performance to ensure reliable heating and cooling year-round.
